    Biotechnology has almost unlimited potential to change our lives in very exciting ways. Many of the chemical reactions that produce these products can be fully optimized by performing them at extremes of temperature, pressure, salinity, and pH for efficient and cost-effective outcomes. Fortunately, there are many organisms (extremophiles) that thrive in extreme environments found in nature and offer an excellent source of replacement enzymes in lieu of mesophilic ones currently used in these processes. In this review, I discuss the current uses and some potential new applications of extremophiles and their products, including enzymes, in biotechnology. PMID:27019700

    Alpha-keto (α-keto) acids are used widely in feeds, food additives, pharmaceuticals, and in chemical synthesis processes. Although most α-keto acids are currently produced by chemical synthesis, their biotechnological production from renewable carbohydrates is a promising new approach. In this mini-review, we first present the different types of α-keto acids as well as their applications; next, we summarize the recent progresses in the biotechnological production of some important α-keto acids; namely, pyruvate, α-ketoglutarate, α-ketoisovalerate, α-ketoisocaproate, phenylpyruvate, α-keto-γ-methylthiobutyrate, and 2,5-diketo-d-gluconate. Finally, we discuss the future prospects as well as favorable directions for the biotechnological production of keto acids that ultimately would be more environment-friendly and simpler compared with the production by chemical synthesis.

    Summary The global demand for crude oil is expected to continue to rise in future while simultaneously oil production is currently reaching its peak. Subsequently, rising oil prices and their negative impacts on economy, together with an increased environmental awareness of our society, directed the focus also on the biotechnological production of fuels. Although a wide variety of such fuels has been suggested, only the production of ethanol and biodiesel has reached a certain economic feasibility and volume, yet. This review focuses on the current state and perspectives of biotechnological production of biodiesel‐like compounds. At present by far most of the produced biodiesel is obtained by chemical transesterification reactions, which cannot meet the demands of a totally ‘green’ fuel production. Therefore, also several biotechnological biodiesel production processes are currently being developed. Biotechnological production can be achieved by purified enzymes in the soluble state, which requires cost‐intensive protein preparation. Alternatively, enzymes could be immobilized on an appropriate matrix, enabling a reuse of the enzyme, although the formation of by‐products may provide difficulties to maintain the enzyme activity. Processes in presence of organic solvents like t‐butanol have been developed, which enhance by‐product solubility and therefore prevent loss of enzyme activity. As another approach the application of whole‐cell catalysis for the production of fatty acid ethyl esters, which is also referred to as ‘microdiesel’, by recombinant microorganisms has recently been suggested.

    In recent years, actions have been undertaken by the Belgian government to promote process innovation and technical diversification. Research programs are initiated and coordinated by the study committee for biotechnology setup within the Institute for Scientific Research in Industry and Agriculture (IRSIA). As a result of this action, the main areas where biotechnological processes are developed or commercially exploited include plant genetics, protein engineering, hybridoma technology, biopesticides, production by genetic engineering of vaccines and drugs, monoclonal detection of human and animal deseases, process reactors for aerobic and anaerobic wastewater treatment, and genetic modification of yeast and bacteria as a base for biomass and energy. Development research also includes new fermentation technologies principally based on immobilization of microorganisms, reactor design, and optimization of unit operations involved in downstream processing. Food, pharmaceutical, and chemical industries are involved in genetic engineering and biotechnology and each of these sectors is overviewed in this paper.

  11. Public perceptions of biotechnology.

    PubMed

    McHughen, Alan

    2007-09-01

    The very term 'Biotechnology' elicits a range of emotions, from wonder and awe to downright fear and hostility. This is especially true among non-scientists, particularly in respect of agricultural and food biotechnology. These emotions indicate just how poorly understood agricultural biotechnology is and the need for accurate, dispassionate information in the public sphere to allow a rational public debate on the actual, as opposed to the perceived, risks and benefits of agricultural biotechnology. This review considers first the current state of public knowledge on agricultural biotechnology, and then explores some of the popular misperceptions and logical inconsistencies in both Europe and North America. I then consider the problem of widespread scientific illiteracy, and the role of the popular media in instilling and perpetuating misperceptions. The impact of inappropriate efforts to provide 'balance' in a news story, and of belief systems and faith also impinges on public scientific illiteracy. Getting away from the abstract, we explore a more concrete example of the contrasting approach to agricultural biotechnology adoption between Europe and North America, in considering divergent approaches to enabling coexistence in farming practices. I then question who benefits from agricultural biotechnology. Is it only the big companies, or is it society at large--and the environment--also deriving some benefit? Finally, a crucial aspect in such a technologically complex issue, ordinary and intelligent non-scientifically trained consumers cannot be expected to learn the intricacies of the technology to enable a personal choice to support or reject biotechnology products. The only reasonable and pragmatic alternative is to place trust in someone to provide honest advice. But who, working in the public interest, is best suited to provide informed and accessible, but objective, advice to wary consumers?

    Modern biotechnology is one of the most important scientific and technological revolutions in the 21st century, with an increasing and measurable impact on society. Development of biotechnology curriculum has become important to high school bioscience classrooms. This study has monitored high school students in Taiwan on their knowledge of and attitudes towards biotechnology for nearly two decades. Not surprisingly, knowledge of biotechnology of current students has increased significantly (p < 0.001) and most students have learned some definitions and examples of biotechnology. There was a positive correlation between biotechnology knowledge and attitudes toward biotechnology for current students who study Advanced Biology (AB). However, for current students who did not study AB, there was a negative correlation.The attitude results showed that students today expressed less favorable opinions toward agricultural biotechnology (p < 0.001) despite studying AB or not. However, there is no significant difference between students today and 18 years ago in opinions towards medical biotechnology. In addition, current students showed a greater concern involving environmental risks than former students. Interestingly, the high school curriculum did affect students' attitudes toward genetically engineered (GE) plants but not GE animals. Our current study also found that the students' attitude towards GE animals was influenced more by their limited knowledge than by their moral belief. On the basis of findings from this study, we suggest that more materials of emerging animal biotechnology should be included in high school curriculum and recommend that high school teachers and university faculty establish a collaborative framework in the near future. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(5):475-491, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

  14. Diatom cultivation and biotechnologically relevant products. Part II: current and putative products.

    PubMed

    Lebeau, T; Robert, J-M

    2003-02-01

    While diatoms are widely present in terms of diversity and abundance in nature, few species are currently used for biotechnologically applications. Most studies have focussed on intracellularly synthesised eicosapentaenoic acid (EPA), a polyunsaturated fatty acid (PUFA) used for pharmaceutical applications. Applications for other intracellular molecules, such as total lipids for biodiesel, amino acids for cosmetic, antibiotics and antiproliferative agents, are at the early stage of development. In addition, the active principle component must be identified amongst the many compounds of biotechnological interest. Biomass from diatom culture may be applied to: (1). aquaculture diets, due to the lipid- and amino-acid-rich cell contents of these microorganisms, and (2). the treatment of water contaminated by phosphorus and nitrogen in aquaculture effluent, or heavy metal (bioremediation). The most original application of microalgal biomass, and specifically diatoms, is the use of silicon derived from frustules in nanotechnology. The competitiveness of biotechnologically relevant products from diatoms will depend on their cost of production. Apart from EPA, which is less expensive when obtained from Phaeodactylum tricornutum than from cod liver, comparative economic studies of other diatom-derived products as well as optimisation of culture conditions are needed. Extraction of intracellular metabolites should be also optimised to reduce production costs, as has already been shown for EPA. Using cell immobilisation techniques, benthic diatoms can be cultivated more efficiently allowing new, biotechnologically relevant products to be investigated.

    Theobroma cacao-The Food of the Gods, provides the raw material for the multibillion dollar chocolate industry and is also the main source of income for about 6 million smallholders around the world. Additionally, cocoa beans have a number of other nonfood uses in the pharmaceutical and cosmetic industries. Specifically, the potential health benefits of cocoa have received increasing attention as it is rich in polyphenols, particularly flavonoids. At present, the demand for cocoa and cocoa-based products in Asia is growing particularly rapidly and chocolate manufacturers are increasing investment in this region. However, in many Asian countries, cocoa production is hampered due to many reasons including technological, political and socio-economic issues. This review provides an overview of the present status of global cocoa production and recent advances in biotechnological applications for cacao improvement, with special emphasis on genetics/genomics, in vitro embryogenesis and genetic transformation. In addition, in order to obtain an insight into the latest innovations in the commercial sector, a survey was conducted on granted patents relating to T. cacao biotechnology. © 2017 The Authors.

    A study was carried out on the construction of indicators in biotechnology in Costa Rica as part of the project "SYMBIOSIS, Cooperative Program for the Construction of Indicators in Biotechnology adapted to Latin American and Caribbean countries, to motivate the application and transference of industrial technologies". The study focused on two units: researchers and research projects developed in Costa Rica, between 1998 and 2002. For researchers, information was collected about indicators related to sex, age, teaching activities, number of projects, academic degree, area of speciality and number of publications. For research projects we obtained information about: speciality, sector of application, duration of projects and number of researchers per project. Very interesting results include the high participation of the women in this area of investigation (54%); the low participation of young researchers (13% younger than 30), and a high proportion of the investigators that are responsible for 4 or more projects (42%). With relation to the specialities of the projects, the majority are in the category Bio-Agro (39%) whereas in Acuaculture only 1% was found. The sectors of application with the most number of projects are: Agriculture and Livestock (37%) and Human Health (35%). The main strengthts and limitatations for the development of biotechnology in Costa Rica are discussed.

  1. Ethical limitations in patenting biotechnological inventions.

    PubMed

    Lugagnani, V

    1999-01-01

    In order to connect ethical considerations with practical limits to patentability, the moral judgement should possibly move from the exploitation of the invention to the nature and/or objectives of Research and Development (R&D) projects which have produced it: in other words, it appears quite reasonable and logical that Society is not rewarding unethical R&D activities by granting intellectual property rights. As far as biotechnology R&D is concerned, ethical guidance can be derived from the 1996 Council of EuropeOs OConvention for the protection of human rights and dignity of the human being with regard to the application of biology and medicineO, whose Chapter V - Scientific research - provides guidelines on: i. protection of persons undergoing research (e.g. informed consent); ii. protection of persons not able to consent to research; iii. research on embryos in vitro. As far as the specific point of patenting biotechnology inventions is concerned, the four exclusions prescribed by Directive 98/44/EC (i.e. human cloning, human germ-line gene therapy, use of human embryos for commercial purposes, unjustified animal suffering for medical purposes) are all we have in Europe in terms of ethical guidance to patentability. In Italy, in particular, we certainly need far more comprehensive legislation, expressing SocietyOs demand to provide ethical control of modern biotechnology. However it is quite difficult to claim that ethical concerns are being raised by currently awarded biotechnology patents related to living organisms and material thereof; they largely deal with the results of genomic R&D, purposely and usefully oriented toward improving health-care and agri-food processes, products and services. ONo patents on lifeOO can be an appealing slogan of militants against modern biotechnology, but it is far too much of an over-simplified abstraction to become the Eleventh Commandment our Society.

    2018-03-01

    The plant Cannabis sativa contains a number of psychoactive chemical compounds, the cannabinoids, which possess a significant pharmaceutical potential. Recently, the usage of Cannabis for medicinal purposes was legalized in many countries. Thus, the study on the influence of different cannabinoids in combination with other Cannabis -derived compounds with respect to the treatment of various diseases becomes increasingly important. Besides the production of distinct cannabinoids in a heterologous host, like tobacco or yeast, transgenic Cannabis plants would be a suitable alternative to modify and therefore optimize the cannabinoid profile. This perspective highlights the current efforts on Cannabis cell culture systems, in vitro propagation, and transformation of the plant and reveals the resulting opportunities concerning biotechnological production of cannabinoids. Furthermore, alternative platform organisms for the heterologous production of cannabinoids, like tobacco, are considered and evaluated. Georg Thieme Verlag KG Stuttgart · New York.

    Fungal habitats include soil, water, and extreme environments. With around 100,000 fungus species already described, it is estimated that 5.1 million fungus species exist on our planet, making fungi one of the largest and most diverse kingdoms of eukaryotes. Fungi show remarkable metabolic features due to a sophisticated genomic network and are important for the production of biotechnological compounds that greatly impact our society in many ways. In this review, we present the current state of knowledge on fungal biodiversity, with special emphasis on filamentous fungi and the most recent discoveries in the field of identification and production of biotechnological compounds. More than 250 fungus species have been studied to produce these biotechnological compounds. This review focuses on three of the branches generally accepted in biotechnological applications, which have been identified by a color code: red, green, and white for pharmaceutical, agricultural, and industrial biotechnology, respectively. We also discuss future prospects for the use of filamentous fungi in biotechnology application.

    The purpose of this review is to survey current, emerging and predicted future biotechnologies which are impacting, or are likely to impact in the future on the life sciences, with a projection for the coming 20 years. This review is intended to discuss current and future technical strategies, and to explore areas of potential growth during the foreseeable future. Information technology approaches have been employed to gather and collate data. Twelve broad categories of biotechnology have been identified which are currently impacting the life sciences and will continue to do so. In some cases, technology areas are being pushed forward by the requirement to deal with contemporary questions such as the need to address the emergence of anti-microbial resistance. In other cases, the biotechnology application is made feasible by advances in allied fields in biophysics (e.g. biosensing) and biochemistry (e.g. bio-imaging). In all cases, the biotechnologies are underpinned by the rapidly advancing fields of information systems, electronic communications and the World Wide Web together with developments in computing power and the capacity to handle extensive biological data. A rationale and narrative is given for the identification of each technology as a growth area. These technologies have been categorized by major applications, and are discussed further. This review highlights: Biotechnology has far-reaching applications which impinge on every aspect of human existence. The applications of biotechnology are currently wide ranging and will become even more diverse in the future. Access to supercomputing facilities and the ability to manipulate large, complex biological datasets, will significantly enhance knowledge and biotechnological development.

    Many archaea colonize extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties, they are a potentially valuable resource in the development of novel biotechnological processes. Despite extensive research, however, there are few existing industrial applications of either archaeal biomass or archaeal enzymes. This review summarizes current knowledge about the biotechnological uses of archaea and archaeal enzymes with special attention to potential applications that are the subject of current experimental evaluation. Topics covered include cultivation methods, recent achievements in genomics, which are of key importance for the development of new biotechnological tools, and the application of wild-type biomasses, engineered microorganisms, enzymes and specific metabolites in particular bioprocesses of industrial interest.

    PubMed Central

    2017-01-01

    ABSTRACT The filamentous fungus Ashbya gossypii has long been considered a paradigm of the White Biotechnology in what concerns riboflavin production. Its industrial relevance led to the development of a significant molecular and in silico modeling toolbox for its manipulation. This, together with the increasing knowledge of its genome and metabolism has helped designing effective metabolic engineering strategies for optimizing riboflavin production, but also for developing new A. gossypii strains for novel biotechnological applications, such as production of recombinant proteins, single cell oils (SCOs), and flavour compounds. With the recent availability of its genome-scale metabolic model, the exploration of the full biotechnological potential of A. gossypii is now in the spotlight. Here, we will discuss some of the challenges that these emerging A. gossypii applications still need to overcome to become economically attractive and will present future perspectives for these and other possible biotechnological applications for A. gossypii.

    2005-12-01

    Biotechnology-derived food crops are currently being developed in Malaysia mainly for disease resistance and improved post harvest quality. The modern biotechnology approach is adopted because of its potential to overcome constraints faced by conventional breeding techniques. Research on the development of biotechnology-derived papaya, pineapple, chili, passion fruit, and citrus is currently under way. Biotechnology-derived papaya developed for resistance to papaya ringspot virus (PRSV) and improved postharvest qualities is at the field evaluation stage. Pineapple developed for resistance to fruit black heart disorder is also being evaluated for proof-of-concept. Other biotechnology-derived food crops are at early stages of gene cloning and transformation. Activities and products involving biotechnology-derived crops will be fully regulated in the near future under the Malaysian Biosafety Law. At present they are governed only by guidelines formulated by the Genetic Modification Advisory Committee (GMAC), Malaysia. Commercialization of biotechnology-derived crops involves steps that require GMAC approval for all field evaluations and food-safety assessments before the products are placed on the market. Public acceptance of the biotechnology product is another important factor for successful commercialization. Understanding of biotechnology is generally low among Malaysians, which may lead to low acceptance of biotechnology-derived products. Initiatives are being taken by local organizations to improve public awareness and acceptance of biotechnology. Future research on plant biotechnology will focus on the development of nutritionally enhanced biotechnology-derived food crops that can provide more benefits to consumers.

    Are science educators providing secondary school students with the background to understand the science behind recent controversies such as the recently introduced compulsory labelling of genetically modified foods? Research from the UK suggests that many secondary school students do not understand the processes or implications of modern biotechnology. The situation in Australia is unclear. In this study, 1116 15-year-old students from eleven Western Australian schools were surveyed to determine their understanding of, and attitude towards, recent advances in modern biotechnology. The results indicate that approximately one third of students have little or no understanding of biotechnology. Many students over-estimate the use of biotechnology in our society by confusing current uses with possible future applications. The results provide a rationale for the inclusion of biotechnology, a cutting edge science, in the school science curriculum

    1985-09-01

    The food processing industry is the oldest and largest industry using biotechnological processes. Further development of food products and processes based on biotechnology depends upon the improvement of existing processes, such as fermentation, immobilized biocatalyst technology, and production of additives and processing aids, as well as the development of new opportunities for food biotechnology. Improvements are needed in the characterization, safety, and quality control of food materials, in processing methods, in waste conversion and utilization processes, and in currently used food microorganism and tissue culture systems. Also needed are fundamental studies of the structure-function relationship of food materials and of the cell physiology and biochemistry of raw materials.

    2017-01-01

    Primordial germ cells (PGCs) generate new individuals through differentiation, maturation and fertilization. This means that the manipulation of PGCs is directly linked to the manipulation of individuals, making PGCs attractive target cells in the animal biotechnology field. A unique biological property of avian PGCs is that they circulate temporarily in the vasculature during early development, and this allows us to access and manipulate avian germ lines. Following the development of a technique for transplantation, PGCs have become central to avian biotechnology, in contrast to the use of embryo manipulation and subsequent transfer to foster mothers, as in mammalian biotechnology. Today, avian PGC transplantation combined with recent advanced manipulation techniques, including cell purification, cryopreservation, depletion, and long-term culture in vitro, have enabled the establishment of genetically modified poultry lines and ex-situ conservation of poultry genetic resources. This chapter introduces the principles, history, and procedures of producing avian germline chimeras by transplantation of PGCs, and the current status of avian germline modification as well as germplasm cryopreservation. Other fundamental avian reproductive technologies are described, including artificial insemination and embryo culture, and perspectives of industrial applications in agriculture and pharmacy are considered, including poultry productivity improvement, egg modification, disease resistance impairment and poultry gene "pharming" as well as gene banking.

    Colombi, A; Maroni, M; Foà, V

    1989-01-01

    Biotechnology has been defined as the application of biological organisms, systems or processes to manufacturing and service industries. In considering health aspects of biotechnological development it must be underlined that the use of microorganisms in traditional industries, such as the production of food, bread, beer and dairy products, has not added significantly to the more usual industrial hazards. The risk factors encountered in the biotechnology industry can be defined as general, i.e., common to other industrial activities, and specific, i.e., depending on the presence of microorganisms and/or their metabolic products. The specific health risks vary according to the type of process, but can be grouped into three main categories: immunological diseases, toxic effects; pathological effects of microorganisms. Allergic immunological diseases such as bronchial asthma, contact dermatitis, oculo-rhinitis and extrinsic allergic alveolitis are by far the most frequent and well known diseases occurring among workers employed on biotechnological production. Toxic effects were observed among workers employed on the production of antibiotics and hormones or single cell proteins, where absorption of endotoxins has been described. Infectious diseases may arise from uncontrolled dissemination of pathogenic microorganisms through aerosols, dusts, aqueous and semisolid sludge effluents from biotechnological plants. The greatest risks occur in the production of antiviral vaccines, in research laboratories and in waste-water treatment plants. Risk of pathogenic effects has also been speculated from exposure to engineered microorganisms in laboratory and environmental or agricultural applications. Safety precautions consisting of protective measures, and effective barriers of containment (both physical and biological) have to be advised according to the hazardous characteristics of the organisms.(ABSTRACT TRUNCATED AT 250 WORDS)

    This study questions the presumed relation between formal schooling and scientific literacy about biotechnologies. Comparing science and nonscience majors' knowledge of and attitudes toward biotechnological applications, conclusions are drawn if their formal learnings improve pupils' understandings of and attitudes toward biotechnology applications. Sample of the study consists of 403 undergraduate and graduate students, 198 nonscience, and 205 science majors. The Biotechnology Knowledge Questionnaire and the Biotechnology Attitude Questionnaire were administered. Descriptive statistics (mean and percentages), t test, and correlations were used to examine the participants' knowledge of biotechnology and attitudes toward biotechnological applications and differences as regards their majors. Although the science majors had higher knowledge and attitude scores than the nonscience majors, it is not possible to say that they have sufficient knowledge of biotechnologies. Besides, the participants' attitudes toward biotechnological applications were not considerably related to their knowledge of biotechnology. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):115-125, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

    Embryo biotechnology has become one of the prominent high businesses worldwide. This technology has evolved through three major changes, that is, traditional embryo transfer (in vivo embryo production by donor superovulation), in vitro embryo production by ovum pick up with in vitro fertilization and notably current cloning technique by somatic cell nuclear transfer and transgenic animal production. Embryo biotechnology has widely been used in dairy and beef cattle industry and commercial bovine embryo transfer has become a large international business. Currently, many developed biotechnologies during the period from early oocyte stage to pre-implantation embryos can be used to create new animal breeds and accelerate genetic progression. Based on recent advances in embryo biotechnologies and authors current studies, this review will focus on a description of the application of this technology to beef cattle improvement and discuss how to use this technology to accelerate beef cattle breeding and production. The main topics of this presentation include the following: (i) how to increase calf production numbers from gametes including sperm and oocyte; (ii) multiple ovulation and embryo transfer breeding schemes; (iii) in vitro fertilization and intracytoplasm sperm injection in bovine; (iv) pronuclear development and transgenic animals; (v) sex selection from sperm and embryos; (vi) cloning and androgenesis; (vii) blastocyst development and embryonic stem cells; (viii) preservation of beef cattle genetic resources; and (ix) conclusions. © 2011 Blackwell Verlag GmbH.

    Zajc, Jožica; Erjavec, Karmen

    2014-08-01

    While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

    Biotechnological methods have become an important tool in pharmaceutical drug research and development. Today approximately 15 % of drug revenues are derived from biopharmaceuticals. The most relevant indications are oncology, metabolic disorders and disorders of the musculoskeletal system. For the future it can be expected that the relevance of biopharmaceuticals will further increase. Currently, the share of substances in preclinical testing that rely on biotechnology is more than 25 % of all substances in preclinical testing. Products for the treatment of cancer, metabolic disorders and infectious diseases are most important. New therapeutic approaches such as RNA interference only play a minor role in current commercial drug research and development with 1.5 % of all biological preclinical substances. Investments in sustainable high technology such as biotechnology are of vital importance for a highly developed country like Germany because of its lack of raw materials. Biotechnology helps the pharmaceutical industry to develop new products, new processes, methods and services and to improve existing ones. Thus, international competitiveness can be strengthened, new jobs can be created and existing jobs preserved.

    New crops are gradually establishing along with cultivation systems to reduce reliance on depleting fossil fuel reserves and sustain better adaptation to climate change. These biological assets could be efficiently exploited as bioenergy feedstocks. Bioenergy crops are versatile renewable sources with the potential to alternatively contribute on a daily basis towards the coverage of modern society's energy demands. Biotechnology may facilitate the breeding of elite energy crop genotypes, better suited for bio-processing and subsequent use that will improve efficiency, further reduce costs, and enhance the environmental benefits of biofuels. Innovative molecular techniques may improve a broad range of important features including biomass yield, product quality and resistance to biotic factors like pests or microbial diseases or environmental cues such as drought, salinity, freezing injury or heat shock. The current review intends to assess the capacity of biotechnological applications to develop a beneficial bioenergy pipeline extending from feedstock development to sustainable biofuel production and provide examples of the current state of the art on future energy crops.

    2013-09-01

    Yeasts are the major producer of biotechnology products worldwide, exceeding production in capacity and economic revenues of other groups of industrial microorganisms. Yeasts have wide-ranging fundamental and industrial importance in scientific, food, medical, and agricultural disciplines (Fig. 1). Saccharomyces is the most important genus of yeast from fundamental and applied perspectives and has been expansively studied. Non-Saccharomyces yeasts (non-conventional yeasts) including members of the Ascomycetes and Basidiomycetes also have substantial current utility and potential applicability in biotechnology. In an earlier mini-review, "Biotechnology of non-Saccharomyces yeasts-the ascomycetes" (Johnson Appl Microb Biotechnol 97: 503-517, 2013), the extensive biotechnological utility and potential of ascomycetous yeasts are described. Ascomycetous yeasts are particularly important in food and ethanol formation, production of single-cell protein, feeds and fodder, heterologous production of proteins and enzymes, and as model and fundamental organisms for the delineation of genes and their function in mammalian and human metabolism and disease processes. In contrast, the roles of basidiomycetous yeasts in biotechnology have mainly been evaluated only in the past few decades and compared to the ascomycetous yeasts and currently have limited industrial utility. From a biotechnology perspective, the basidiomycetous yeasts are known mainly for the production of enzymes used in pharmaceutical and chemical synthesis, for production of certain classes of primary and secondary metabolites such as terpenoids and carotenoids, for aerobic catabolism of complex carbon sources, and for bioremediation of environmental pollutants and xenotoxicants. Notwithstanding, the basidiomycetous yeasts appear to have considerable potential in biotechnology owing to their catabolic utilities, formation of enzymes acting on recalcitrant substrates, and through the production of unique primary

    Extracellular electron transfer (EET) is a type of microbial respiration that enables electron transfer between microbial cells and extracellular solid materials, including naturally-occurring metal compounds and artificial electrodes. Microorganisms harboring EET abilities have received considerable attention for their various biotechnological applications, in addition to their contribution to global energy and material cycles. In this review, current knowledge on microbial EET and its application to diverse biotechnologies, including the bioremediation of toxic metals, recovery of useful metals, biocorrosion, and microbial electrochemical systems (microbial fuel cells and microbial electrosynthesis), were introduced. Two potential biotechnologies based on microbial EET, namely the electrochemical control of microbial metabolism and electrochemical stimulation of microbial symbiotic reactions (electric syntrophy), were also discussed.

    A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, sustainable, and environmentally friendly microbial biocements and biogrouts for the construction ground improvement. The microbial polysaccharides are used as admixtures for cement. Microbially produced biodegradable bioplastics can be used for the temporarily constructions. The bioagents that are used in construction biotechnologies are either pure or enrichment cultures of microorganisms or activated indigenous microorganisms of soil. The applications of microorganisms in the construction processes are bioaggregation, biocementation, bioclogging, and biodesaturation of soil. The biotechnologically produced construction materials and the microbially-mediated construction technologies have a lot of advantages in comparison with the conventional construction materials and processes. Proper practical implementations of construction biotechnologies could give significant economic and environmental benefits.

    Blue biotechnology, in which aquatic environments provide the inspiration for various products such as food additives, aquaculture, biosensors, green chemistry, bioenergy, and pharmaceuticals, holds enormous promise. Large-scale efforts to sequence aquatic genomes and metagenomes, as well as campaigns to isolate new organisms and culture-based screenings, are helping to push the boundaries of known organisms. Mass spectrometry-based proteomics can complement 16S gene sequencing in the effort to discover new organisms of potential relevance to blue biotechnology by facilitating the rapid screening of microbial isolates and by providing in depth profiles of the proteomes and metaproteomes of marine organisms, both model cultivable isolates and, more recently, exotic non-cultivable species and communities. Proteomics has already contributed to blue biotechnology by identifying aquatic proteins with potential applications to food fermentation, the textile industry, and biomedical drug development. In this review, we discuss historical developments in blue biotechnology, the current limitations to the known marine biosphere, and the ways in which mass spectrometry can expand that knowledge. We further speculate about directions that research in blue biotechnology will take given current and near-future technological advancements in mass spectrometry. Copyright © 2014 Elsevier B.V.

    2011-12-01

    Animation has great potential for improving the way people learn. A number of studies in different scientific disciplines have shown that instruction involving computer animations can facilitate the understanding of processes at the molecular level. However, using animation alone does not ensure learning. Students sometimes miss essential features when they watch only animations, mainly due to the cognitive load involved. Moreover, students seem to attribute a great deal of authority to the computer and may develop misconceptions by taking animations of abstract concepts too literally. In this study, we attempted to explore teachers' perceptions concerning the use of animations in the classroom while studying biotechnological methods, as well as the teachers' contribution to the enactment of animations in class. Thirty high-school biotechnology teachers participated in a professional development workshop, aimed at investigating how teachers plan for and support learning with animation while studying biotechnological methods in class. From that sample, two teachers agreed to participate in two case studies aimed at characterizing teachers' contribution to the enactment of animations in class while studying biotechnological methods. Our findings reveal marked teacher contribution in the following three aspects: establishing the "hands-on" point of view, helping students deal with the cognitive load that accompanies the use of animation, and implementing constructivist aspects of knowledge construction while studying using animations.

    Apple (Malus domestica Borkh.), which is a widely cultivated, important economic fruit crop with nutritive and medicinal importance, has emerged as a model horticultural crop in this post-genomic era. Apple cultivation is heavily dependent on climatic condition and is susceptible to several diseases caused by fungi, bacteria, viruses, insects, etc. Extensive research work has been carried out to standardize tissue culture protocols and utilize them in apple improvement. We review the in vitro shoot multiplication, rooting, transformation and regeneration methodologies in apple and tabulate various such protocols for easy reference. The utility and limitation of transgenesis in apple improvement have also been summarized. The concepts of marker-free plants, use of non-antibiotic resistance selectable markers, and cisgenic and intragenic approaches are highlighted. Furthermore, the limitations, current trends and future prospects of tissue culture-mediated biotechnological interventions in apple improvement are discussed.

    Microalgae constitute a diverse group of eukaryotic unicellular organisms that are of interest for pure and applied research. Owing to their natural synthesis of value-added natural products microalgae are emerging as a source of sustainable chemical compounds, proteins and metabolites, including but not limited to those that could replace compounds currently made from fossil fuels. For the model microalga, Chlamydomonas reinhardtii, this has prompted a period of rapid development so that this organism is poised for exploitation as an industrial biotechnology platform. The question now is how best to achieve this? Highly advanced industrial biotechnology systems using bacteria and yeasts were established in a classical metabolic engineering manner over several decades. However, the advent of advanced molecular tools and the rise of synthetic biology provide an opportunity to expedite the development of C. reinhardtii as an industrial biotechnology platform, avoiding the process of incremental improvement. In this review we describe the current status of genetic manipulation of C. reinhardtii for metabolic engineering. We then introduce several concepts that underpin synthetic biology, and show how generic parts are identified and used in a standard manner to achieve predictable outputs. Based on this we suggest that the development of C. reinhardtii as an industrial biotechnology platform can be achieved more efficiently through adoption of a synthetic biology approach. Significance Statement Chlamydomonas reinhardtii offers potential as a host for the production of high value compounds for industrial biotechnology. Synthetic biology provides a mechanism to generate generic, well characterised tools for application in the rational genetic manipulation of organisms: if synthetic biology principles were adopted for manipulation of C. reinhardtii, development of this microalga as an industrial biotechnology platform would be expedited.

    Biotechnology in India has made great progress in the development of infrastructure, manpower, research and development and manufacturing of biological reagents, biodiagnostics, biotherapeutics, therapeutic and, prophylactic vaccines and biodevices. Many of these indigenous biological reagents, biodiagnostics, therapeutic and prophylactic vaccines and biodevices have been commercialized. Commercially when biotechnology revenue has reached $25 billions in the U.S. alone in 2000 excluding the revenues of biotech companies that were acquired by pharmaceutical companies, India has yet to register a measurable success. The conservative nature and craze of the Indian Industry for marketing imported biotechnology products, lack of Government support, almost non-existing national healthcare system and lack of trained managers for marketing biological and new products seem to be the important factors responsible for poor economic development of biotechnology in India. With the liberalization of Indian economy, more and more imported biotechnology products will enter into the Indian market. The conditions of internal development of biotechnology are not likely to improve in the near future and it is destined to grow only very slowly. Even today biotechnology in India may be called to be in its infancy.

    Microalgae constitute a diverse group of eukaryotic unicellular organisms that are of interest for pure and applied research. Owing to their natural synthesis of value-added natural products microalgae are emerging as a source of sustainable chemical compounds, proteins and metabolites, including but not limited to those that could replace compounds currently made from fossil fuels. For the model microalga, Chlamydomonas reinhardtii, this has prompted a period of rapid development so that this organism is poised for exploitation as an industrial biotechnology platform. The question now is how best to achieve this? Highly advanced industrial biotechnology systems using bacteria and yeasts were established in a classical metabolic engineering manner over several decades. However, the advent of advanced molecular tools and the rise of synthetic biology provide an opportunity to expedite the development of C. reinhardtii as an industrial biotechnology platform, avoiding the process of incremental improvement. In this review we describe the current status of genetic manipulation of C. reinhardtii for metabolic engineering. We then introduce several concepts that underpin synthetic biology, and show how generic parts are identified and used in a standard manner to achieve predictable outputs. Based on this we suggest that the development of C. reinhardtii as an industrial biotechnology platform can be achieved more efficiently through adoption of a synthetic biology approach. © 2015 The Authors The Plant Journal published by Society for Experimental Biology and John Wiley & Sons Ltd.

    Xu, Yan; Wang, Dong; Fan, Wen Lai; Mu, Xiao Qing; Chen, Jian

    The earliest industrial biotechnology originated in ancient China and developed into a vibrant industry in traditional Chinese liquor, rice wine, soy sauce, and vinegar. It is now a significant component of the Chinese economy valued annually at about 150 billion RMB. Although the production methods had existed and remained basically unchanged for centuries, modern developments in biotechnology and related fields in the last decades have greatly impacted on these industries and led to numerous technological innovations. In this chapter, the main biochemical processes and related technological innovations in traditional Chinese biotechnology are illustrated with recent advances in functional microbiology, microbial ecology, solid-state fermentation, enzymology, chemistry of impact flavor compounds, and improvements made to relevant traditional industrial facilities. Recent biotechnological advances in making Chinese liquor, rice wine, soy sauce, and vinegar are reviewed.

    This article traces back thirty years of biotechnology research sponsored by the European Union (EU). It outlines the crucial role played by De Nettancourt, Goffeau and Van Hoeck to promote and prepare the first European programme on biotechnology (1982-1986) run by the European Commission. Following this first biotechnology programme, others followed until the current one, part of the seventh Framework Programme for Research, Technological Development and Demonstration (2007-2013) (FP7). Particular attention is given to the statutory role of the European institutions in the design and orientation of the successive biotechnology programmes, compared to the more informal-yet visionary-role of key individuals upstream to any legislative decision. Examples of success stories and of the role of the biotechnology programmes in addressing societal issues and industrial competitiveness are also presented. Finally, an outline of Horizon 2020, the successor of FP7, is described, together with the role of biotechnology in building the bioeconomy. Copyright © 2012 Elsevier B.V. All rights reserved.

    The term biotechnology first appeared in the programs of the Scientific and Technological Research Council of Turkey (TUBITAK) in 1982. The State Planning Organization (SPO) in 1988 defined biotechnology and the scientific fields. Moreover, it put forward an institutional framework and suggested priority areas for research and development. Turkey has been researching and investing in biotechnology for almost four decades. This review covers the development of science and technology policy with its history, consensus and consequences, bio-industries in Turkey, and research activities in biotechnology at Turkish Universities. Details are provided by the research groups in response to a common request for information on their activities and major publications in the field. The information provided has been grouped under thematic topics within the broad theme of biotechnology, and summarized within these topics. Although many aspects of biotechnological research are being pursued in Turkey, it appears that the most common research activities of the field are in fermentation processes, environmental biotechnology, and biomedical engineering.

    Thailand faces a significant burden in terms of treating and managing degenerative and chronic diseases. Moreover, incidences of rare diseases are rising. Many of these-such as diabetes, cancer, and inherited inborn metabolic diseases-have no definite treatments or cure. Meanwhile, advanced health biotechnology has been found, in principle, to be an effective solution for these health problems. Qualitative approaches were employed to analyse the current situation and examine existing public policies related to advanced health biotechnologies in Thailand. The results of this analysis were then used to formulate policy recommendations. Our research revealed that the system in Thailand in relation to advanced health biotechnologies is fragmented, with multiple unaddressed gaps, underfunding of research and development (R&D), and a lack of incentives for the private sector. In addition, there are no clear definitions of advanced health biotechnologies, and coverage pathways are absent. Meanwhile, false advertising and misinformation are prevalent, with no responsible bodies to actively and effectively provide appropriate information and education (I&E). The establishment of a specialised institution to fill the gaps in this area is warranted. The development and implementation of a comprehensive national strategic plan related to advanced health biotechnologies, greater investment in R&D and I&E for all stakeholders, collaboration among agencies, harmonisation of reimbursement across public health schemes, and provision of targeted I&E are specifically recommended.

    Agriculture, industry and medicine are being altered by new biological technologies. Today's students are the citizens who will make decisions about associated ethical issues. They need to have the knowledge that will enable them to make informed choices. Hence biotechnology has an important place in science education. The aims of the research were to: 1. describe the state of biotechnology teaching in NSW; 2. determine whether teachers in NSW do not teach biotechnology because they do not have the necessary knowledge and experience; 3. identify other reasons why NSW teachers choose not to teach biotechnology; 4. describe problems encountered in teaching biotechnology in NSW; 5. suggest ways in which the problems encountered in the teaching of biotechnology can be overcome. Quantitative and qualitative methods were used in a complementary way to investigate these aims. In a sample of teachers surveyed, many reported that they chose not to teach biotechnology because they did not have adequate knowledge and experience. Other obstacles were identified. These were: 1. the difficulty of the subject matter; 2. the lack of practical work; 3. lack of a program for biotechnology in junior science. The results of this trial suggested that a biotechnology unit should be developed in collaboration with the teacher and that time needs to be made available for school based program development.

    Agriculture, industry and medicine are being altered by new biotechnologies. Biotechnology education is important because todays students and citizens will make decisions about the development and application of these new molecular biologies. This article reports an investigation of the teaching of biotechnology in an Australian state, New South Wales (NSW). In NSW few students were electing to answer examination questions related to biotechnology, suggesting that few students were studying the topic. This study looks at why electives relating to biotechnology are chosen or not chosen by students and teachers, with the intention of developing a greater understanding of the requirements for provision of a successful unit of study in this subject. Data was obtained through a survey of secondary science teachers, interviews with teachers and two case studies of the teaching of a biotechnology unit. Teachers reported a range of obstacles to the teaching of biotechnology including the difficulty of the subject matter and a lack of practical work that was suited to the content of the teaching unit. If biotechnology is worth learning in school science, then further research is needed to identify ways to promote the effective teaching of this topic, which teachers regard as important for, and interesting to, students but which most teachers choose not to teach.

    Filamentous fungi are well known for their capability of producing antibiotic natural products. Recent studies have demonstrated the potential of antimicrobials with vast chemodiversity from marine fungi. Development of such natural products into lead compounds requires sustainable supply. Marine biotechnology can significantly contribute to the production of new antibiotics at various levels of the process chain including discovery, production, downstream processing, and lead development. However, the number of biotechnological processes described for large-scale production from marine fungi is far from the sum of the newly-discovered natural antibiotics. Methods and technologies applied in marine fungal biotechnology largely derive from analogous terrestrial processes and rarely reflect the specific demands of the marine fungi. The current developments in metabolic engineering and marine microbiology are not yet transferred into processes, but offer numerous options for improvement of production processes and establishment of new process chains. This review summarises the current state in biotechnological production of marine fungal antibiotics and points out the enormous potential of biotechnology in all stages of the discovery-to-development pipeline. At the same time, the literature survey reveals that more biotechnology transfer and method developments are needed for a sustainable and innovative production of marine fungal antibiotics.

    The second part of the biotechnology awareness study focused on health sciences libraries and how well they are meeting the needs of biotechnologists working in the study's nine medical centers. A survey was conducted over a three-month period to assess the demand for biotechnology-related reference services at nine libraries and the sources the librarians used to answer the questions. Data on monographic and current serial holdings were also collected. At the end of the survey period, librarians were asked for their perceptions about biotechnology research at their institutions and in their geographic areas. Their responses were compared to the responses the scientists at the nine schools gave to the same or similar questions. Results showed few biotechnology-related reference questions were asked of the librarians. The recorded questions dealt with a range of biotechnology subjects. MEDLINE was used to answer 77% of the questions received during the survey period. More detailed notes in MeSH and a guide to online searching for biotechnology topics were suggested by the librarians as ways to improve reference service to this group of researchers. Journal collections were generally strong, with libraries owning from 50% to 87% of the titles on a core list of biotechnology journals compiled for this study. All libraries subscribed to the five titles most often cited by the scientists surveyed. Generally, librarians were unaware of the biotechnology-related research being done on their campuses or in their geographic areas. PMID:1998819

    Dyes are natural and xenobiotic compounds that make the world more beautiful through coloured substances. However, the release of coloured wastewaters represents a serious environmental problem and a public health concern. Colour removal, especially from textile wastewaters, has been a big challenge over the last decades, and up to now there is no single and economically attractive treatment that can effectively decolourise dyes. In the passed years, notable achievements were made in the use of biotechnological applications to textile wastewaters not only for colour removal but also for the complete mineralization of dyes. Different microorganisms such as aerobic and anaerobic bacteria, fungi and actinomycetes have been found to catalyse dye decolourisation. Moreover, promising results were obtained in accelerating dye decolourisation by adding mediating compounds and/or changing process conditions to high temperatures. This paper provides a critical review on the current technologies available for decolourisation of textile wastewaters and it suggests effective and economically attractive alternatives.

Of Kansas; Max Planck Institute for dynamics of Complex Technical Systems; Fraunhofer USA Center for Molecular Biotechnology; US Dep. of Agriculture Animal and Plant Health Inspection Service, etc. In historic literature there are data about inoculation practices in antique China, Persia, India, Byzantium, native Americans, some African population. In modern immunology since the end of XIX century the vaccines were produced at the in vivo platforms - in animals (rabbits, mice, cows). Since 1931 due to E. Goodpasture' elaboration most virus vaccines were and are produced at the in ovo platform. In 1949 J.F. Enders elaborated large-scale polio virus production in the primary culture of monkey kidney cells in vitro. Up to day primary culture of chiken embrio fibroblasts are used to large-scale production of vaccine viruses of measles, mumps, rabies. Since 2000-th in Western countries most part of virus vaccines were began to produced via a cultivation in continuous tumor cell lines. The last technology is the most low cost for large-scale production of vaccines.

    Spermatogonial stem cells (SSCs) are the germ stem cells of the seminiferous epithelium in the testis. Through the process of spermatogenesis, they produce sperm while concomitantly keeping their cellular pool constant through self-renewal. SSC biology offers important applications for animal reproduction and overcoming human disease through regenerative therapies. To this end, several techniques involving SSCs have been developed and will be covered in this article. SSCs convey genetic information to the next generation, a property that can be exploited for gene targeting. Additionally, SSCs can be induced to become embryonic stem cell-like pluripotent cells in vitro. Updates on SSC transplantation techniques with related applications, such as fertility restoration and preservation of endangered species, are also covered on this article. SSC suspensions can be transplanted to the testis of an animal and this has given the basis for SSC functional assays. This procedure has proven technically demanding in large animals and men. In parallel, testis tissue xenografting, another transplantation technique, was developed and resulted in sperm production in testis explants grafted into ectopical locations in foreign species. Since SSC culture holds a pivotal role in SSC biotechnologies, current advances are overviewed. Finally, spermatogenesis in vitro, already demonstrated in mice, offers great promises to cope with reproductive issues in the farm animal industry and human clinical applications.

    Since the 1970s, biotechnology has been a key innovator in drug development. An analysis of FDA-approved therapeutics demonstrates pharmaceutical companies outpace biotechs in terms of new approvals but biotechnology companies are now responsible for earlier-stage activities (patents, INDs or clinical development). The number of biotechnology organizations that contributed to an FDA approval began declining in the 2000s and is at a level not seen since the 1980s. Whereas early biotechnology companies had a decade from first approval until acquisition, the average acquisition of a biotechnology company now occurs months before their first FDA approval. The number of hybrid organizations that arise when pharmaceutical companies acquire biotechnology is likewise declining, raising questions about the sustainability of biotechnology.

    In Aotearoa (New Zealand), the government funded studies on communicating biotechnology to different sectors in the community from 2003 to 2006. Subsequently, a researcher covering the Māori sector performed a content analysis of data gathered in the community. Qualitative analysis methods included examining text from participant interviews, focus groups, government documents, newspapers, Internet sites, and current literature. Content was coded by identifying common themes in the English and the Māori language. Words like genetic modification (GM), genetic engineering (GE), and biotechnology were explained to provide a basic understanding between the communities and researcher. The terminology applied in the research was essential to achieve communication between the researcher and the community. The resultant themes represented seven views to interpret the communities association with biotechnology: purist Māori, religious Māori, anti Māori, pro Māori, no Māori, uncertain Māori, and middle Māori views. The themes are taken from the analysis of data compiled after 3 years of completing different stages of a research project. The views indicate that a common understanding can be achieved in the diverse range of Māori tribal communities providing those communicating biotechnology can identify the view and interpretations communities associate with biotechnology. This knowledge is essential for government agencies, researchers, community practitioners, scientist, and businesses that desire to dialogue with Māori communities in the language of biotechnology.

    This paper tries to yield an economic valuation of biotechnological activities in terms of aggregated production and employment. This valuation goes beyond direct estimation and includes the indirect effects derived from sectorial linkages between biotechnological activities and the rest of economic system. To deal with the proposed target several sources of data have been used, including official data from National Statistical Office (INE) such us national accounts, input-output tables, and innovation surveys, as well as, firms' level balance sheets and income statements and also specific information about research projects compiled by Genoma Spain Foundation. Methodological approach is based on the estimation of a new input-output table which includes the biotechnological activities as a specific branch. This table offers both the direct impact of these activities and the main parameters to obtain the induced effects over the rest of the economic system. According to the most updated available figures, biotechnological activities would have directly generated almost 1,600 millions of euros in 2005, and they would be employed more than 9,000 workers. But if we take into account the full linkages with the rest of the system, the macroeconomic impact of Biotechnological activities would reach around 5,000 millions euros in production terms (0.6% of total GDP) and would be responsible, directly or indirectly, of more than 44,000 employments.

    A workshop entitled "Challenges and Opportunities in Evaluating Protein Allergenicity across Biotechnology Industries" was held at the 51st Annual Meeting of the Society of Toxicology (SOT) in San Francisco, California. The workshop was sponsored by the Biotechnology Specialty Section of SOT and was designed to present the science-based approaches used in biotechnology industries to evaluate and regulate protein allergenicity. A panel of experts from industry and government highlighted the allergenicity testing requirements and research in the agricultural, pharmaceutical/biopharma, and vaccine biotechnology industries and addressed challenges and opportunities for advancing the science of protein allergenicity. The main learning from the workshop was that immunoglobulin E-mediated allergenicity of biotechnology-derived products is difficult to assess without human data. The approaches currently being used to evaluate potential for allergenicity across biotechnology industries are very different and range from bioinformatics, in vitro serology, in vivo animal testing, in vitro and in vivo functional assays, and "biosimilar" assessments (ie, biotherapeutic equivalents to innovator products). The challenge remains with regard to the different or lack of regulatory requirements for allergenicity testing across industries, but the novel approaches being used with bioinformatics and biosimilars may lead to opportunities in the future to collaborate across biotechnology industries.

    The marriage of biotechnology and the pharmaceutical industry (pharma) is predicated on an evolution in technology and product innovation. It has come as a result of advances in both the science and the business practices of the biotechnology sector in the past 30 years. Biotechnology products can be thought of as "intelligent pharmaceuticals," in that they often provide novel mechanisms of action, new approaches to disease control, higher clinical success rates, improved patient care, extended patent protection, and a significant likelihood of reimbursement. Although the first biotechnology product, insulin, was approved just 32 years ago in 1982, today there are more than 200 biotechnology products commercially available. Research has expanded to include more than 900 biotechnology products in clinical trials. Pharma is substantially engaged in both the clinical development of these products and their commercialization.

    The ISS Biotechnology Facility (BTF) platform provides scientists with a unique opportunity to carry out diverse experiments in a microgravity environment for an extended period of time. Although considerable progress has been made in preserving cells on the ISS for long periods of time for later return to Earth, future biotechnology experiments would desirably monitor, process, and analyze cells in a timely way on-orbit. One aspect of our work has been directed towards developing biochemical sensors for pH, glucose, oxygen, and carbon dioxide for perfused bioreactor system developed at Johnson Space Center. Another aspect is the examination and identification of new and advanced commercial biotechnologies that may have applications to on-orbit experiments.

    Biotechnology is a collective term for a large number of manipulations of biological material. Fields of importance in stock-keeping include: (1) manipulation of reproductive processes; (2) genetic manipulation of macro-(farm) animals and micro-organisms and (3) manipulation of metabolism. Fitting in biotechnological findings in breeding-stock farming has repercussions in several fields such as the relationship between producers and the ancillary and processing industries, service industries, consumers and society as a whole. The use of biotechnical findings will also require further automation and adaptation of farm management. Biotechnology opens up a new area and new prospects for farm animal husbandry. These can only be regarded as positive when they take a permanent development of the entire section into account.

    This paper is a commentary to a paper by Anne Solli, Frank Bach and Björn Åkerman on how students at a technical university learn to argue as biotechnologists. Solli and her colleagues report from an ethnographic study performed during the first semester of a 5-year program in biotechnology at a technical university in Sweden. Their study demonstrates how students begin to acquire `the right way' of approaching the controversial issue of producing and consuming genetically modified organisms. In my response I discuss the ethnographic account of this particular educational practice in terms of social and cultural production/reproduction of a biotechnology community and how the participants (students and teaching professors) deal with the dialectic of individual and collective transformation. In the perspective of the biotechnology community, the work done by the teaching professor becomes a way of ensuring the future of the biotechnology community in terms of what values and objectives are held highly in the community of practice.

    Cut flower markets are developing in many countries as the international demand for cut flowers is rapidly growing. Developing new varieties with modified characteristics is an important aim in floriculture. Production of transgenic ornamental plants can shorten the time required in the conventional breeding of a cultivar. Biotechnology tools in combination with conventional breeding methods have been used by cut flower breeders to change flower color, plant architecture, post-harvest traits, and disease resistance. In this review, we describe advances in genetic engineering that have led to the development of new cut flower varieties. Copyright © 2016 Elsevier Inc. All rights reserved.

    Due to the important impact that biotechnology has on current Western societies, well-informed critical citizens are needed. People prepared to make conscious decisions about aspects of biotechnology that relate to their own lives. Teachers play a central role in all education systems. Thus, the biotechnological literacy of preservice teachers is an important consideration as they will become an influential collective as future teachers of the next generation of children. The attitudes toward science (and biotechnology) that teachers have affect their behavior and influence the way they implement their daily practice of science teaching in school. This study analyzes the attitudes and knowledge of Spanish preservice teachers toward biotechnology. We designed a new survey instrument that was completed by 407 university students who were taking official degree programs in preschool and primary education. Our results point out that although they are aware of biotechnology applications, topics concerning the structure of DNA, management of genetic information inside the cell, genetically modified organism technology and the use of microorganisms as biotechnological tools were not correctly answered. According to our attitude analysis, Spanish preservice teachers could be defined as opponents of genetically modified product acquisition, supporters of biotechnology for medical purposes and highly interested in increasing their knowledge about biotechnology and other scientific advances. Our results show a positive correlation between better knowledge and more positive attitudes toward biotechnology. A Spanish preservice teacher with positive attitudes toward biotechnology tends to be a student with a strong biology background who scored good marks in our knowledge test.

    Our education system aims to equip young people with the knowledge, problem-solving skills and values to cope with an increasingly technological society. The aim of this study was to determine the effect of biotechnology education on adolescents’ understanding and attitudes about processes associated with biotechnology. Data were drawn from teacher and student interviews and surveys in the context of innovative Year 10 biotechnology courses conducted in three Western Australian high schools. The results indicate that after completing a biotechnology course students’ understanding increased but their attitudes remained constant with the exception of their views about human uses of gene technology. The findings of this study have ramifications for the design and implementation of biotechnology education courses in high schools.

    2015-01-01

    L-DOPA (3,4-dihydroxyphenyl-L-alanine) has been widely used as a drug for Parkinson's disease caused by deficiency of the neurotransmitter dopamine. Since Monsanto developed the commercial process for L-DOPA synthesis for the first time, most of currently supplied L-DOPA has been produced by the asymmetric method, especially asymmetric hydrogenation. However, the asymmetric synthesis shows critical limitations such as a poor conversion rate and a low enantioselectivity. Accordingly, alternative biotechnological approaches have been researched for overcoming the shortcomings: microbial fermentation using microorganisms with tyrosinase, tyrosine phenol-lyase, or p-hydroxyphenylacetate 3-hydroxylase activity and enzymatic conversion by immobilized tyrosinase. Actually, Ajinomoto Co. Ltd commercialized Erwinia herbicola fermentation to produce L-DOPA from catechol. In addition, the electroenzymatic conversion system was recently introduced as a newly emerging scheme. In this review, we aim to not only overview the biotechnological L-DOPA production methods, but also to briefly compare and analyze their advantages and drawbacks. Furthermore, we suggest the future potential of biotechnological L-DOPA production as an industrial process.

    Advances in understanding plant biology, novel genetic resources, genome modification, and omics technologies generate new solutions for food security and novel biomaterials production under changing environmental conditions. New gene and germplasm candidates that are anticipated to lead to improved crop yields and other plant traits under stress have to pass long development phases based on trial and error using large-scale field evaluation. Therefore, quantitative, objective, and automated screening methods combined with decision-making algorithms are likely to have many advantages, enabling rapid screening of the most promising crop lines at an early stage followed by final mandatory field experiments. The combination of novel molecular tools, screening technologies, and economic evaluation should become the main goal of the plant biotechnological revolution in agriculture.

    For more than three decades the field of biotechnology has had an extraordinary impact on science, health care, law, the regulatory environment, and business. During this time more than 260 novel biotechnology products were approved for over 230 indications. Global sales of these products exceeded $175 billion in 2013 and have helped sustain a vibrant life sciences sector that includes more than 4,600 biotech companies worldwide. In this article we examine the evolution of biotechnology during the past three decades and the profound impact that it has had on health care through four interrelated and interdependent tracks: innovations in science, government activity, business development, and patient care. The future impact of biotechnology is promising, as long as the public and private sectors continue to foster policies and provide funds that lead to scientific breakthroughs; governments continue to offer incentives for private-sector biotech innovation; industry develops business models for cost-effective research and development; and all stakeholders establish policies to ensure that the therapeutic advances that mitigate or cure medical conditions that currently have inadequate or no available therapies are accessible to the public at a reasonable cost.

    Mannans of different structure and composition are renewable bioresources that can be widely found as components of lignocellulosic biomass in softwood and agricultural wastes, as non-starch reserve polysaccharides in endosperms and vacuoles of a wide variety of plants, as well as a major component of yeast cell walls. Enzymatic hydrolysis of mannans using mannanases is essential in the pre-treatment step during the production of second-generation biofuels and for the production of potentially health-promoting manno-oligosaccharides (MOS). In addition, mannan-degrading enzymes can be employed in various biotechnological applications, such as cleansing and food industries. In this review, fundamental knowledge of mannan structures, sources and functions will be summarized. An update on various aspects of mannan-degrading enzymes as well as the current status of their production, and a critical analysis of the potential application of MOS in food and feed industries will be given. Finally, emerging areas of research on mannan biotechnology will be highlighted.

    Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists' public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi-structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non-scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.

    Ice-binding proteins (IBPs), such as antifreeze proteins (AFPs) and ice-nucleating proteins (INPs), have been described in diverse cold-adapted organisms, and their potential applications in biotechnology have been recognized in various fields. Currently, both IBPs are being applied to biotechnological processes, primarily in medicine and the food industry. However, our knowledge regarding the diversity of bacterial IBPs is limited; few studies have purified and characterized AFPs and INPs from bacteria. Phenotypically verified IBPs have been described in members belonging to Gammaproteobacteria, Actinobacteria and Flavobacteriia classes, whereas putative IBPs have been found in Gammaproteobacteria, Alphaproteobacteria and Bacilli classes. Thus, the main goal of this minireview is to summarize the current information on bacterial IBPs and their application in biotechnology, emphasizing the potential application in less explored fields such as agriculture. Investigations have suggested the use of INP-producing bacteria antagonists and AFPs-producing bacteria (or their AFPs) as a very attractive strategy to prevent frost damages in crops. UniProt database analyses of reported IBPs (phenotypically verified) and putative IBPs also show the limited information available on bacterial IBPs and indicate that major studies are required. © FEMS 2016.

    Arsenic (As), a naturally occurring metallic element, is a dreadful health hazard to millions of people across the globe. Arsenic is present in low amount in the environment and originates from anthropogenic impact and geogenic sources. The presence of As in groundwater used for irrigation is a worldwide problem as it affects crop productivity, accumulates to different tissues and contaminates food chain. The consumption of As contaminated water or food products leads to several diseases and even death. Recently, studies have been carried out to explore the biochemical and molecular mechanisms which contribute to As toxicity, accumulation, detoxification and tolerance acquisition in plants. This information has led to the development of the biotechnological tools for developing plants with modulated As tolerance and detoxification to safeguard cellular and genetic integrity as well as to minimize food chain contamination. This review aims to provide current updates about the biochemical and molecular networks involved in As uptake by plants and the recent developments in the area of functional genomics in terms of developing As tolerant and low As accumulating plants.

    Cyanobacteria hold significant potential as industrial biotechnology (IB) platforms for the production of a wide variety of bio-products ranging from biofuels such as hydrogen, alcohols and isoprenoids, to high-value bioactive and recombinant proteins. Underpinning this technology, are the recent advances in cyanobacterial “omics” research, the development of improved genetic engineering tools for key species, and the emerging field of cyanobacterial synthetic biology. These approaches enabled the development of elaborate metabolic engineering programs aimed at creating designer strains tailored for different IB applications. In this review, we provide an overview of the current status of the fields of cyanobacterial omics and genetic engineering with specific focus on the current molecular tools and technologies that have been developed in the past five years. The paper concludes by giving insights on future commercial applications of cyanobacteria and highlights the challenges that need to be addressed in order to make cyanobacterial industrial biotechnology more feasible in the near future.

    Biotechnology uses substances, materials or extracts derived from living cells, employing 22 million Europeans in a € 1.5 Tn endeavour, being the premier global economic growth opportunity this century. Significant advances have been made in red biotechnology using pharmaceutically and medically relevant applications, green biotechnology developing agricultural and environmental tools and white biotechnology serving industrial scale uses, frequently as process feedstocks. Red biotechnology has delivered dramatic improvements in controlling human disease, from antibiotics to overcome bacterial infections to anti-HIV/AIDS pharmaceuticals such as azidothymidine (AZT), anti-malarial compounds and novel vaccines saving millions of lives. Green biotechnology has dramatically increased food production through Agrobacterium and biolistic genetic modifications for the development of 'Golden Rice', pathogen resistant crops expressing crystal toxin genes, drought resistance and cold tolerance to extend growth range. The burgeoning area of white biotechnology has delivered bio-plastics, low temperature enzyme detergents and a host of feedstock materials for industrial processes such as modified starches, without which our everyday lives would be much more complex. Biotechnological applications can bridge these categories, by modifying energy crops properties, or analysing circulating nucleic acid elements, bringing benefits for all, through increased food production, supporting climate change adaptation and the low carbon economy, or novel diagnostics impacting on personalized medicine and genetic disease. Cross-cutting technologies such as PCR, novel sequencing tools, bioinformatics, transcriptomics and epigenetics are in the vanguard of biotechnological progress leading to an ever-increasing breadth of applications. Biotechnology will deliver solutions to unimagined problems, providing food security, health and well-being to mankind for centuries to come. Copyright © 2013

    Rigorous application of a simple definition of what constitutes opposition to agricultural biotechnology readily encompasses a wide array of key players in national and international systems of food production, distribution and governance. Even though the sum of political and financial benefits of opposing agricultural biotechnology appears vastly to outweigh the benefits which accrue to providers of agricultural biotechnology, technology providers actually benefit from this opposition. If these barriers to biotechnology were removed, subsistence farmers still would not represent a lucrative market for improved seed. The sum of all interests involved ensures that subsistence farmers are systematically denied access to agricultural biotechnology. Copyright © 2010 Elsevier B.V. All rights reserved.

    The application of biotechnology is a potential tool for mitigating the present and future fooding and clothing demands in developing countries like India. The commercialization of biotechnological products might benefiting the poor`s in developing countries are unlikely to be developed. Biotechnology has the potential to provide a wide range of products and the existing production skills in the industrial, pharmaceuticals and the agricultural sector. Ownership of the intellectual property rights is the key factors in determining the success of any technological invention, which was introduced in the market. It provides the means for technological progress to continue of the industry of the country. The new plans, animal varieties, new methods of treatments, new crops producing food articles as such are the inventions of biotechnology. Biotechnology is the result of the application of human intelligence and knowledge to the biological processes. Most of the tools of biotechnology have been developed, by companies, governments, research in- stitutes and universities in developed nations. These human intellectual efforts deserve protection. India is a developing country with advance biotechnology based segments of pharmaceutical and agricultural industries. The Trade Related Intellectual Property Rights (TRIPS) is not likely to have a significant impact on incentives for innovation creation in the biotechnology sectors. In the recent years, the world has seen the biotechnology sector as one of greatest investment area through the Patent Law and will giving huge profit in future. The Research and Development in the field of biotechnology should be encouraged for explor- ing new tools and improve the biological systems for interest of the common people. Priority should be given to generation, evaluation, protection and effective commercial utilization of tangible products of intellectual property in agriculture and pharmaceuticals.

While GM foods, foods derived from biotechnology, are popular with growers and producers, they are still a matter of some concern among consumers. In fact, our recent surveys showed that Japanese consumers had become uneasy about the potential health risks of genetically modified foods. Many Japanese consumers have only vague ideas about the actual health risks, and they appear to be making decisions simply by rejecting GM food because of non-informed doubts. Although the debate about GM foods has increased in the mass media and scientific journals, few articles concerning direct studies on the potential toxicity or adverse health effects of GM foods have appeared. The roles of relevant international regulatory bodies in ensuring that GM crops and food are safe are therefore have summarized. Finally, the current debate on use of GM crops in agriculture and future trends for development of GM foods with enriched nutrients, better functionality, and medicinal ingredients, which will be of direct benefit to the consumer, are covered.

    Abstract Increasing global population, urbanization and industrialization are increasing the rate of conversion of arable land into wasteland. Supplying food to an ever-increasing population is one of the biggest challenges that agriculturalists and plant scientists are currently confronting. Environmental stresses make this situation even graver. Despite the induction of several tolerance mechanisms, sensitive plants often fail to survive under environmental extremes. New technological approaches are imperative. Conventional breeding methods have a limited potential to improve plant genomes against environmental stress. Recently, genetic engineering has contributed enormously to the development of genetically modified varieties of different crops such as cotton, maize, rice, canola and soybean. The identification of stress-responsive genes and their subsequent introgression or overexpression within sensitive crop species are now being widely carried out by plant scientists. Engineering of important tolerance pathways, like antioxidant enzymes, osmolyte accumulation, membrane-localized transporters for efficient compartmentation of deleterious ions and accumulation of essential elements and resistance against pests or pathogens is also an area that has been intensively researched. In this review, the role of biotechnology and its successes, prospects and challenges in developing stress-tolerant crop cultivars are discussed. PMID:28775828

  18. Re-Framing Biotechnology Regulation.

    PubMed

    Peck, Alison

    Biotechnology is about to spill the banks of federal regulation. New genetic engineering techniques like CRISPR-Cas9 promise revolutionary breakthroughs in medicine, agriculture, and public health—but those techniques would not be regulated under the terms of the Coordinated Framework for Regulation of Biotechnology. This revolutionary moment in biotechnology offers an opportunity to correct the flaws in the framework, which was hastily patched together at the advent of the technology. The framework has never captured all relevant technologies, has never satisfied the public that risk is being effectively managed, and has never been accessible to small companies and publicly-funded labs that increasingly are positioned to make radical, life-saving innovations. This Article offers a proposal for new legislation that would reshape biotechnology regulation to better meet these goals. Key reforms include tying regulation to risk rather than technology category; consolidating agency review; capturing distinct regulatory expertise through inter-agency consultations; creating a clearinghouse to help guide applicants and disseminate information; setting up more comprehensive monitoring of environmental effects; and providing federal leadership to fill key data gaps and address socio-economic impacts.

    This article reviews biotechnology legislation in the 50 states for 11 policy areas spanning 1990-2010, an era of immense growth in biotechnology, genetic knowledge, and significant policy development. Policies regarding health insurance, life insurance, long-term care insurance, DNA data bank collection, biotech research protection, biotech promotion and support, employment discrimination, genetic counselor licensing, human cloning, and genetic privacy each represent major policy responses arising from biotechnology and coinciding with key areas of state regulation (insurance, criminal justice, economic development, labor law, health and safety, privacy, and property rights). This analysis seeks to answer three questions regarding biotechnology legislation at the state level: who is acting (policy adoption), when is policy adopted (policy timing), and what is policy doing (policy content). Theoretical concerns examine state ideology (conservative or liberal), policy type (economic or moral), and the role of external events (federal law, news events, etc.) on state policy adoption. Findings suggest ideological patterns in adoption, timing, and content of biotech policy. Findings also suggest economic policies tend to be more uniform in content than moral policies, and findings also document a clear link between federal policy development, external events, and state policy response.

  20. An updated view on horseradish peroxidases: recombinant production and biotechnological applications.

    Horseradish peroxidase has been the subject of scientific research for centuries. It has been used exhaustively as reporter enzyme in diagnostics and histochemistry and still plays a major role in these applications. Numerous studies have been conducted on the role of horseradish peroxidase in the plant and its catalytic mechanism. However, little progress has been made in its recombinant production. Until now, commercial preparations of horseradish peroxidase are still isolated from plant roots. These preparations are commonly mixtures of various isoenzymes of which only a small fraction has been described so far. The composition of isoenzymes in these mixed isolates is subjected to uncontrollable environmental conditions. Nowadays, horseradish peroxidase regains interest due to its broad applicability in the fields of medicine, life sciences, and biotechnology in cancer therapy, biosensor systems, bioremediation, and biocatalysis. These medically and commercially relevant applications, the recent discovery of new natural isoenzymes with different biochemical properties, as well as the challenges in recombinant production render this enzyme particularly interesting for future biotechnological solutions. Therefore, we reviewed previous studies as well as current developments with biotechnological emphasis on new applications and the major remaining biotechnological challenge-the efficient recombinant production of horseradish peroxidase enzymes.

    Johnson, D Barrie

    2013-11-01

    Metal mining faces a number of significant economic and environmental challenges in the twenty-first century for which established and emerging biotechnologies may, at least in part, provide the answers. Bioprocessing of mineral ores and concentrates is already used in variously engineered formats to extract base (e.g., copper, cobalt, and nickel) and precious (gold and silver) metals in mines throughout the world, though it remains a niche technology. However, current projections of an increasing future need to use low-grade primary metal ores, to reprocess mine wastes, and to develop in situ leaching technologies to extract metals from deep-buried ore bodies, all of which are economically more amenable to bioprocessing than conventional approaches (e.g., pyrometallurgy), would suggest that biomining will become more extensively utilized in the future. Recent research has also shown that bioleaching could be used to process a far wider range of metal ores (e.g., oxidized ores) than has previously been the case. Biotechnologies are also being developed to control mine-related pollution, including securing mine wastes (rocks and tailings) by using "ecological engineering" approaches, and also to remediate and recover metals from waste waters, such as acid mine drainage. This article reviews the current status of biotechnologies within the mining sector and considers how these may be developed and applied in future years.

    The eight Millennium Development Goals (MDGs) are international development targets for the year 2015 that aim to achieve relative improvements in the standards of health, socioeconomic status and education in the world's poorest countries. Many of the challenges addressed by the MDGs reflect the direct or indirect consequences of subsistence agriculture in the developing world, and hence, plant biotechnology has an important role to play in helping to achieve MDG targets. In this opinion article, we discuss each of the MDGs in turn, provide examples to show how plant biotechnology may be able to accelerate progress towards the stated MDG objectives, and offer our opinion on the likelihood of such technology being implemented. In combination with other strategies, plant biotechnology can make a contribution towards sustainable development in the future although the extent to which progress can be made in today's political climate depends on how we deal with current barriers to adoption.

    With the advent of a new era of astrobiology missions in the exploration of the solar system and the search for evidence of life elsewhere, we present a new approach to this goal, the integration of biotechnology. We have reviewed the current list of biotechnology techniques, which are applicable to miniaturization, automatization and integration into a combined flight platform. Amongst the techniques reviewed are- The uses of antibodies- Fluorescent detection strategies- Protein and DNA chip technology- Surface plasmon resonance and its relation to other techniques- Micro electronic machining (MEMS where applicable to biologicalsystems)- nanotechnology (e.g. molecular motors)- Lab-on-a-chip technology (including PCR)- Mass spectrometry (i.e. MALDI-TOF)- Fluid handling and extraction technologies- Chemical Force Microscopy (CFM)- Raman Spectroscopy We have begun to integrate this knowledge into a single flight instrument approach for the sole purpose of combining several mutually confirming tests for life, organic and/or microbial contamination, as well as prebiotic and abiotic organic chemicals. We will present several innovative designs for new instrumentation including pro- engineering design drawings of a protein chip reader for space flight and fluid handling strategies. We will also review the use of suitable extraction methodologies for use on different solar system bodies.

    Johnson, Eric A

    2013-01-01

    Saccharomyces cerevisiae and several other yeast species are among the most important groups of biotechnological organisms. S. cerevisiae and closely related ascomycetous yeasts are the major producer of biotechnology products worldwide, exceeding other groups of industrial microorganisms in productivity and economic revenues. Traditional industrial attributes of the S. cerevisiae group include their primary roles in food fermentations such as beers, cider, wines, sake, distilled spirits, bakery products, cheese, sausages, and other fermented foods. Other long-standing industrial processes involving S. cerevisae yeasts are production of fuel ethanol, single-cell protein (SCP), feeds and fodder, industrial enzymes, and small molecular weight metabolites. More recently, non-Saccharomyces yeasts (non-conventional yeasts) have been utilized as industrial organisms for a variety of biotechnological roles. Non-Saccharomyces yeasts are increasingly being used as hosts for expression of proteins, biocatalysts and multi-enzyme pathways for the synthesis of fine chemicals and small molecular weight compounds of medicinal and nutritional importance. Non-Saccharomyces yeasts also have important roles in agriculture as agents of biocontrol, bioremediation, and as indicators of environmental quality. Several of these products and processes have reached commercial utility, while others are in advanced development. The objective of this mini-review is to describe processes currently used by industry and those in developmental stages and close to commercialization primarily from non-Saccharomyces yeasts with an emphasis on new opportunities. The utility of S. cerevisiae in heterologous production of selected products is also described.

    : The last decades witnessed a strong growth in several areas of biotechnology, especially in fields related to health, as well as in industrial biotechnology. Advances in molecular engineering now enable biotechnologists to design more efficient pathways in order to convert a larger spectrum of renewable resources into industrially used biofuels and chemicals as well as into new pharmaceuticals and therapeutic proteins. In addition material sciences advanced significantly making it more and more possible to integrate biology and engineering. One of the key questions currently is how to develop new ways of engineering biological systems to cope with the complexity and limitations given by the cell. The options to integrate biology with classical engineering advanced cell free technologies in the recent years significantly. Cell free protein production using cellular extracts is now a well-established universal technology for production of proteins derived from many organisms even at the milligram scale. Among other applications it has the potential to supply the demand for a multitude of enzymes and enzyme variants facilitating in vitro metabolic engineering. This review will briefly address the recent achievements and limitations of cell free conversions. Especially, the requirements for reactor systems in cell free biotechnology, a currently underdeveloped field, are reviewed and some perspectives are given on how material sciences and biotechnology might be able to advance these new developments in the future.

    A plenary discussion session on 'Biotechnology education and training programs' at the Xth International Conference on The global Impacts of Applied Microbiology in 1995 gave an opportunity to identify current priorities for biotechnology in developing countries. The discussion focused on three major areas: the nature of the skills required; education and training for the various categories of staff; the role of the scientific community in informing the decision makers about biotechnology and its prospects. Comparable discussions are taking place in Europe and elsewhere in the industrialized world. They are exemplified by developments arising from a White Paper on 'Growth, Competitiveness, Employment' published by the European Commission in 1993 which included a reinforcement of the work of the European Initiative for Biotechnology Education (EIBE) for teachers in schools. There are also widespread anxieties about the effects of deficiencies in the amount of attention being given to microbiology in undergraduate courses.

    The intent of this project was to expand Northern Virginia Community College's capability to offer training to support the Biotechnology Industry in the northern Virginia region. The general goal of this project was to create a College Biotechnology Program; specific goals of the project were to a) design curricula/courses to prepare students to become entry-level lab technicians, b) redesign and equip lab space to better suit the needs of the program, c) develop partnerships with the local industry through outreach and the formation on an advisory board, d) recruit students into the program, and e) provide instructional support for localmore » high school teachers. At the end of the grant period, NOVA has successfully created two new curricula in biotechnology: an Associate of Applied Science (A.A.S.) in Biotechnology (initiated in Fall 2008) and a Career Studies Certificate for Biotechnology Lab Technicians (to be initiated in Fall 2010). These curricula were designed with advice from an external advisory committee which is comprised of representatives from industry, transfer institutions and high school administrators. To date, almost all courses have been designed and piloted; the equipment needed for the courses and the initial supplies were paid for by the grant as was the re-modeling of some lab space to be used for the biotech courses. In order to market the program, the NOVA Biotech Program has also established relationships with the local high schools. Presentations were given at several local high schools and on-site workshops were held for high school students and teachers. As a result, close to 1000 students have attended program open houses, presentations within the high schools, or workshops held in the summer. Over 100 teachers have received information and/or training in biotechnology. These outreach efforts as well as high quality curricula have started to attract a number of students to the program – for example, there are currently 70

    Lignocellulosic biomass is an important feedstock for a potential future bio-based economy. Owing to its compact structure, suitable decomposition technologies will be necessary to make it accessible for biotechnological conversion. While chemical and enzymatic hydrolysis are currently established methods, a promising alternative is provided by fast pyrolysis. The main resulting product thereof, referred to as pyrolysis oil, is an energy-rich and easily transportable liquid. Many of the identified constituents of pyrolysis oil, however, have previously been reported to display adverse effects on microbial growth. In this Opinion we discuss relevant biological, biotechnological, and technological challenges that need to be addressed to establish pyrolysis oil as a reliable microbial feedstock for a bio-based economy of the future.

    Termites have many unique evolutionary adaptations associated with their eusocial lifestyles. Recent omics research has created a wealth of new information in numerous areas of termite biology (e.g., caste polyphenism, lignocellulose digestion, and microbial symbiosis) with wide-ranging applications in diverse biotechnological niches. Termite biotechnology falls into two categories: (a) termite-targeted biotechnology for pest management purposes, and (b) termite-modeled biotechnology for use in various industrial applications. The first category includes several candidate termiticidal modes of action such as RNA interference, digestive inhibition, pathogen enhancement, antimicrobials, endocrine disruption, and primer pheromone mimicry. In the second category, termite digestomes are deep resources for host and symbiont lignocellulases and other enzymes with applications in a variety of biomass, industrial, and processing applications. Moving forward, one of the most important approaches for accelerating advances in both termite-targeted and termite-modeled biotechnology will be to consider host and symbiont together as a single functional unit.

    2014-06-01

    Most highly controlled and specific applications of microorganisms in biotechnology involve pure cultures. Maintaining single strain cultures is important for industry as contaminants can reduce productivity and lead to longer "down-times" during sterilisation. However, microbes working together provide distinct advantages over pure cultures. They can undertake more metabolically complex tasks, improve efficiency and even expand applications to open systems. By combining rapidly advancing technologies with ecological theory, the use of microbial ecosystems in biotechnology will inevitably increase. This review provides insight into the use of synthetic microbial communities in biotechnology by applying the engineering paradigm of measure, model, manipulate and manufacture, and illustrate the emerging wider potential of the synthetic ecology field. Systems to improve biofuel production using microalgae are also discussed.

    2011-12-20

    This review is based on a study commissioned by the European Commission on the evaluation of scientific, technical and institutional challenges, priorities and bottlenecks for biotechnologies and regional harmonisation of biosafety in Africa. Biotechnology was considered within four domains: agricultural biotechnologies ('Green'), industrial biotechnologies and biotechnologies for environmental remediation ('White'), biotechnologies in aquaculture ('Blue') and biotechnologies for healthcare ('Red'). An important consideration was the decline in partnerships between the EU and developing countries because of the original public antipathy to some green biotechnologies, particularly genetically modified organisms (GMOs) and food from GM crops in Europe. The study focus reported here was West Africa (Ghana, Senegal, Mali and Burkina Faso). The overall conclusion was that whereas high-quality research was proceeding in the countries visited, funding is not sustained and there is little evidence of practical application of biotechnology and benefit to farmers and the wider community. Research and development that was being carried out on genetically modified crop varieties was concentrating on improving food security and therefore unlikely to have significant impact on EU markets and consumers. However, there is much non-controversial green biotechnology such as molecular diagnostics for plant and animal disease and marker-assisted selection for breeding that has great potential application. Regarding white biotechnology, it is currently occupying only a very small industrial niche in West Africa, basically in the sole sector of the production of liquid biofuels (i.e., bio-ethanol) from indigenous and locally planted biomass (very often non-food crops). The presence of diffused small-scale fish production is the basis to develop and apply new (Blue) aquaculture technologies and, where the research conditions and the production sector can permit, to increase this type of

  5. Opportunities for biotechnology and policy regarding mycotoxin issues in international trade.

    PubMed

    Kendra, David F; Dyer, Rex B

    2007-10-20

    Despite being introduced more than a decade ago, agricultural biotechnology still remains framed in controversy impacting both the global economy and international regulations. Controversies surrounding agricultural biotechnology produced crops and foods commonly focus on human and environmental safety, intellectual property rights, consumer choice, ethics, food security, poverty reduction and environmental conservation. Originally, some consumers were reluctant to accept the first generation agricultural biotechnology products because they appeared to primarily benefit agricultural producers; however, it is clear from continued evaluations that these technologies also improved both the safety and wholesomeness of food and helped improve the environment. Plants engineered to resist insect pests and tolerate less toxic pesticides resulted in improved yields thereby enabling farmers to produce more food per acre while reducing the need for herbicides, pesticides, and water and tilling. An indirect benefit of reduced pest damage in transgenic corn expressing genes to control insect pests is lower levels of mycotoxins, most notably those caused by the genus Fusarium. Mycotoxins are an important regulatory issue globally because of their toxic and carcinogenic potential to humans and animals. Complicating this issue is the fact that toxicological databases for mycotoxins are relatively incomplete compared to other food contaminants. Current debates about agricultural biotechnology and mycotoxins reveal significant differences in perception of associated risks and benefits. When faced with uncertainty, regulators tend to set limits as low as possible. Additionally, some regulators invoke the "Precautionary Principle" when limited information is available or disputes over interpretation exist for possible contaminants, including mycotoxins. A major concern regarding use of the "Precautionary Principle" is the appearance that regulators can justify setting any limit on the

  11. Improving value assessment of high-risk, high-reward biotechnology research: the role of 'thick tails'.

    PubMed

    Casault, Sébastien; Groen, Aard J; Linton, Jonathan D

    2014-03-25

    This paper presents work toward improving the efficacy of financial models that describe the unique nature of biotechnology firms. We show that using a 'thick tailed' power law distribution to describe the behavior of the value of biotechnology R&D used in a Real Options Pricing model is significantly more accurate than the traditionally used Gaussian approach. A study of 287 North-American biotechnology firms gives insights into common problems faced by investors, managers and other stakeholders when using traditional techniques to calculate the commercial value of R&D. This is important because specific quantitative tools to assess the value of high-risk, high-reward R&D do not currently exist. This often leads to an undervaluation of biotechnology R&D and R&D intensive biotechnology firms. For example, the widely used Net Present Value (NPV) method assumes a fixed risk ignoring management flexibility and the changing environment. However, Real Options Pricing models assume that commercial returns from R&D investments are described by a normal random walk. A normal random walk model eliminates the possibility of drastic changes to the marketplace resulting from the introduction of revolutionary products and/or services. It is possible to better understand and manage biotechnology research projects and portfolios using a model that more accurately considers large non-Gaussian price fluctuations with thick tails, which recognize the unusually large risks and opportunities associated with Biotechnology R&D. Our empirical data show that opportunity overcompensates for the downside risk making biotechnology R&D statistically more valuable than other Gaussian options investments, which may otherwise appear to offer a similar combination of risk and return.

    Biotechnology is a controversial subject that involves a range of scientific principles from basic tissue culture to genetic manipulation. Proponents include private sector capitalists, public sector researchers, and developing nation governments. Opponents include environmental organizations and social organizations involved in protecting the rights of developing nations. Biotechnology is being presented as the next step after the Green Revolution and the only way that the people of the developing world will be able to feed themselves in the next half century. Research by industrialized nations world wide total an estimated $11 billion with 66% being contributed by the private sector. Biotechnology represents somewhat of a dilemma. Since the majority of the work is being done by the private sector the interests of shareholders and profit are greater done by the private sector the interests of shareholders and profit are greater than that of public welfare or safety. The Consultative Group on International Agricultural Research (CGIAR) is one public sector group that is concerned about this problem. The countries of the developing world fall into 2 categories in relation to use of biotechnology: (1) those that have the potential to adapt imported biotechnologies to local conditions; (2) those that have little or no applied research capacity to effectively use biotechnologies. Currently only Brazil, China, India, and Thailand belong in the 1st category, all other developing countries fall into the 2nd. CGIAR believes it can help in 2 ways: (1) it can provide a bridge for needed information and germplasm between developed and developing countries; (2) it can help to ensure that the agricultural needs of developing countries are not lost. In 1990 CGIAR's plant and animal biotechnology research totaled $14.5 million which was less than 5% of the total CGIAR budget. Networking and institutions building are areas that CGIAR focuses on in an attempt to increase its affect

    Chloroplast genomes defied the laws of Mendelian inheritance at the dawn of plant genetics, and continue to defy the mainstream approach to biotechnology, leading the field in an environmentally friendly direction. Recent success in engineering the chloroplast genome for resistance to herbicides, insects, disease and drought, and for production of biopharmaceuticals, has opened the door to a new era in biotechnology. The successful engineering of tomato chromoplasts for high-level transgene expression in fruits, coupled to hyper-expression of vaccine antigens, and the use of plant-derived antibiotic-free selectable markers, augur well for oral delivery of edible vaccines and biopharmaceuticals that are currently beyond the reach of those who need them most.

    The history of transgenesis is marked by milestones such as the development of cellular transdifferentiation, recombinant DNA, genetic modification of target cells, and finally, the generation of simpler genetically modified organisms (e.g. bacteria and mice). The first transgenic fish was developed in 1984, and since then, continuing technological advancements to improve gene transfer have led to more rapid, accurate, and efficient generation of transgenic animals. Among the established methods are microinjection, electroporation, lipofection, viral vectors, and gene targeting. Here, we review the history of animal transgenesis, with an emphasis on fish, in conjunction with major developments in genetic engineering over the past few decades. Importantly, spermatogonial stem cell modification and transplantation are two common techniques capable of revolutionizing the generation of transgenic fish. Furthermore, we discuss recent progress and future biotechnological prospects of fish transgenesis, which has strong applications for the aquaculture industry. Indeed, some transgenic fish are already available in the current market, validating continued efforts to improve economically important species with biotechnological advancements. Copyright © 2017.

    TerAvest, Michaela A; Ajo-Franklin, Caroline M

    2016-04-01

    Extracellular electron transfer pathways allow certain bacteria to transfer energy between intracellular chemical energy stores and extracellular solids through redox reactions. Microorganisms containing these pathways, exoelectrogens, are a critical part of microbial electrochemical technologies that aim to impact applications in bioenergy, biosensing, and biocomputing. However, there are not yet any examples of economically viable microbial electrochemical technologies due to the limitations of naturally occurring exoelectrogens. Here we first briefly summarize recent discoveries in understanding extracellular electron transfer pathways, then review in-depth the creation of customized and novel exoelectrogens for biotechnological applications. We analyze engineering efforts to increase current production in native exoelectrogens, which reveals that modulating certain processes within extracellular electron transfer are more effective than others. We also review efforts to create new exoelectrogens and highlight common challenges in this work. Lastly, we summarize work utilizing engineered exoelectrogens for biotechnological applications and the key obstacles to their future development. Fueled by the development of genetic tools, these approaches will continue to expand and genetically modified organisms will continue to improve the outlook for microbial electrochemical technologies. © 2015 Wiley Periodicals, Inc.

    Hydrostatic pressure is a well-known physical parameter which is now considered an important variable of life, since organisms have the ability to adapt to pressure changes, by the development of resistance against this variable. In the past decades a huge interest in high hydrostatic pressure (HHP) technology is increasingly emerging among food and biosciences researchers. Microbial specific stress responses to HHP are currently being investigated, through the evaluation of pressure effects on biomolecules, cell structure, metabolic behavior, growth and viability. The knowledge development in this field allows a better comprehension of pressure resistance mechanisms acquired at sub-lethal pressures. In addition, new applications of HHP could arise from these studies, particularly in what concerns to biotechnology. For instance, the modulation of microbial metabolic pathways, as a response to different pressure conditions, may lead to the production of novel compounds with potential biotechnological and industrial applications. Considering pressure as an extreme life condition, this review intends to present the main findings so far reported in the scientific literature, focusing on microorganisms with the ability to withstand and to grow in high pressure conditions, whether they have innated or acquired resistance, and show the potential of the application of HHP technology for microbial biotechnology. © 2013.

    Spiders and scorpions are notorious for their fearful dispositions and their ability to inject venom into prey and predators, causing symptoms such as necrosis, paralysis, and excruciating pain. Information on venom composition and the toxins present in these species is growing due to an interest in using bioactive toxins from spiders and scorpions for drug discovery purposes and for solving crystal structures of membrane-embedded receptors. Additionally, the identification and isolation of a myriad of spider and scorpion toxins has allowed research within next generation antivenoms to progress at an increasingly faster pace. In this review, the current knowledge of spider and scorpion venoms is presented, followed by a discussion of all published biotechnological efforts within development of spider and scorpion antitoxins based on small molecules, antibodies and fragments thereof, and next generation immunization strategies. The increasing number of discovery and development efforts within this field may point towards an upcoming transition from serum-based antivenoms towards therapeutic solutions based on modern biotechnology.

    High-quality research in the field of marine biotechnology is one of the key-factors for successful innovation in exploiting the vast diversity of marine life. However, fascinating scientific research with promising results and claims on promising potential applications (e.g. for pharmaceuticals, nutritional supplements, (feed-)products for aquaculture and bioremediation solutions) is not the only factor to realise the commercial applications of marine biotechnology. What else is needed to exploit the promising potential of marine biotechnology and to create new industrial possibilities? In the study project 'Ocean Farming-Sustainable exploitation of marine organisms', we explore the possibilities of marine organisms to fulfill needs, such as safe and healthy food, industrial (raw) materials and renewable energy in a sustainable way. One of the three design groups is envisioning the future of strong land-based 'marine' market chains. Marine biotechnology is one of the foci of attention in this design group. This article provides a model of future-oriented thinking in which a variety of experts actively participate.

    Traditionally, biotechnology design has focused on the manufacture of chemicals and biologics. Still, a majority of biotechnology products that appear on the market today is the result of mechanical-electric (mechatronic) construction. For these, the biological components play decisive roles in the design solution; the biological entities are either integral parts of the design, or are transformed by the mechatronic system. This article explains how the development and production engineering design principles used for typical mechanical products can be adapted to the demands of biotechnology products, and how electronics, mechanics and biology can be integrated more successfully. We discuss three emerging areas of biotechnology in which mechatronic design principles can apply: stem cell manufacture, artificial organs, and bioreactors. Copyright 2010 Elsevier Ltd.

    The diversity and complexity of biotechnological applications are constantly increasing, with ever expanding ranges of production hosts, cultivation conditions and measurement tasks. Consequently, many analytical and cultivation systems for biotechnology and bioprocess engineering, such as microfluidic devices or bioreactors, are tailor-made to precisely satisfy the requirements of specific measurements or cultivation tasks. Additive manufacturing (AM) technologies offer the possibility of fabricating tailor-made 3D laboratory equipment directly from CAD designs with previously inaccessible levels of freedom in terms of structural complexity. This review discusses the historical background of these technologies, their most promising current implementations and the associated workflows, fabrication processes and material specifications, together with some of the major challenges associated with using AM in biotechnology/bioprocess engineering. To illustrate the great potential of AM, selected examples in microfluidic devices, 3D-bioprinting/biofabrication and bioprocess engineering are highlighted. Copyright © 2017 Elsevier B.V.

  5. Biotechnology and Consumer Decision-Making.

    PubMed

    Sax, Joanna K

    Society is facing major challenges in climate change, health care and overall quality of life. Scientific advances to address these areas continue to grow, with overwhelming evidence that the application of highly tested forms of biotechnology is safe and effective. Despite scientific consensus in these areas, consumers appear reluctant to support their use. Research that helps to understand consumer decision-making and the public’s resistance to biotechnologies such as vaccines, fluoridated water programs and genetically engineered food, will provide great social value. This article is forward-thinking in that it suggests that important research in behavioral decision-making, specifically affect and ambiguity, can be used to help consumers make informed choices about major applications of biotechnology. This article highlights some of the most controversial examples: vaccinations, genetically engineered food, rbST treated dairy cows, fluoridated water, and embryonic stem cell research. In many of these areas, consumers perceive the risks as high, but the experts calculate the risks as low. Four major thematic approaches are proposed to create a roadmap for policymakers to consider for policy design and implementation in controversial areas of biotechnology. This article articulates future directions for studies that implement decision-making research to allow consumers to appropriately assign risk to their options and make informed decisions.

    Tissue-engineered constructs made of biotechnology-derived materials have been preferred due to their chemical and physical composition, which offers both high versatility and a support to enclose/ incorporate relevant signaling molecules and/or genes known to therapeutically induce tissue repair. Herein, a critical overview of the impact of different biotechnology-derived materials, scaffolds, and recombinant signaling molecules over the behavior of cells, another element of tissue engineered constructs, as well its regulatory role in tissue regeneration and disease progression is given. Additionally, these tissue-engineered constructs evolved to three-dimensional (3D) tissue-like models that, as an advancement of two-dimensional standard culture methods, are expected to be a valuable tool in the field of drug discovery and pharmaceutical research. Despite the improved design and conception of current proposed 3D tissue-like models, advanced control systems to enable and accelerate streamlining and automation of the numerous labor-intensive steps intrinsic to the development of tissue-engineered constructs are still to be achieved. In this sense, this review intends to present the biotechnology- derived materials that are being explored in the field of tissue engineering to generate 3D tissue-analogues and briefly highlight their foremost breakthroughs in tissue regeneration and drug discovery. It also aims to reinforce that the crosstalk between tissue engineering and pharmaceutical biotechnology has been fostering the outcomes of tissue engineering approaches through the use of biotechnology-derived signaling molecules. Gene delivery/therapy is also discussed as a forefront area that represents another cross point between tissue engineering and pharmaceutical biotechnology, in which nucleic acids can be considered a "super pharmaceutical" to drive biological responses, including tissue regeneration.

    2002-01-01

    From its inception, biotechnology has been a uniquely international enterprise. An American and an Englishman working together elucidated the structure of DNA almost 50 years ago; more recently, the Human Genome Project linked researchers around the world, from the Baylor College of Medicine in Houston to the Beijing Human Genome Center. Today our industry's researchers hail from African villages and Manhattan high rises; from Munich and Melbourne; from London, Ontario, and London, England; from Scotland and Nova Scotia--New Scotland; from Calcutta and Calgary. But in the beginning, the infrastructure that supported these efforts--intellectual property, venture capital, streamlined technology transfer--was less widely dispersed and the world's brightest biotech researchers clustered in only half a dozen scientific Meccas. Previous technological revolutions have spread around the world. Following in their footsteps, biotechnology's global diaspora seems inevitable, especially since governments are promoting it. But as our science and business emigrate from early strongholds in the United States, Canada and Europe across oceans and borders and into new cultures, international tensions over biotechnology continue to grow. In just the last few years, controversies have rolled over R&D spending priorities, genetic patents, bioprospecting, transgenic agriculture and drug pricing. My premise today is that our industry needs to formulate its first foreign policy, one which is cognizant of the miserable judgments and mistakes of other industries--and avoids them.

    The International Space Station (ISS) will support several facilities dedicated to scientific research. One such facility, the Biotechnology Facility (BTF), is sponsored by the Microgravity Sciences and Applications Division (MSAD) and developed at NASA's Johnson Space Center. The BTF is scheduled for delivery to the ISS via Space Shuttle in April 2005. The purpose of the BTF is to provide: (1) the support structure and integration capabilities for the individual modules in which biotechnology experiments will be performed, (2) the capability for human-tended, repetitive, long-duration biotechnology experiments, and (3) opportunities to perform repetitive experiments in a short period by allowing continuous access to microgravity. The MSAD has identified cell culture and tissue engineering, protein crystal growth, and fundamentals of biotechnology as areas that contain promising opportunities for significant advancements through low-gravity experiments. The focus of this coordinated ground- and space-based research program is the use of the low-gravity environment of space to conduct fundamental investigations leading to major advances in the understanding of basic and applied biotechnology. Results from planned investigations can be used in applications ranging from rational drug design and testing, cancer diagnosis and treatments and tissue engineering leading to replacement tissues.

    Almost from the outset, most large companies saw the 'new biotechnology' not as a new business but as a set of very powerful techniques that, in time, would radically improve the understanding of biological systems. This new knowledge was generally seen by them as enhancing the process of invention and not as a substitute for tried and tested ways of meeting clearly identified targets. As the knowledge base grows, so the big-company response to biotechnology becomes more positive. Within ICI, biotechnology is now integrated into five bio-businesses (Pharmaceuticals, Agrochemicals, Seeds, Diagnostics and Biological Products). Within the Central Toxicology Laboratory it also contributes to the understanding of the mechanisms of toxic action of chemicals as part of assessing risk. ICI has entered two of these businesses (Seeds and Diagnostics) because it sees biotechnology making a major contribution to the profitability of each.

    2001-06-01

    The biotechnology patent debates have revealed deep moral concerns about basic genetics research, R&D and specific biotechnological products, concerns that are seldom taken into consideration in Technology Assessment. In this paper important moral concerns are examined which appear at the various stages of development of a specific genetic product: a predictive genetic test. The purpose is to illustrate the need for a more contextual approach in technology assessment, which integrates the various forms of interaction between bio-technology and society or societal segments. Such an approach will generate greater insight in the moral issues at all stages of a product's life-cycle and this will facilitate decision-making on the 'morality' of a specific biotechnological product.

This paucity of information begs the question of what constitutes a bioethical approach (i.e., respect for individuals or autonomy; beneficence, nonmaleficence, and justice) to marine biotechnology and aquaculture, and whether it is one that is appropriate for consideration. Currently, thoughtful discussion on the bioethical implications of use, development, and commercialization of marine organisms or their products, as well as potential environmental effects, defaults to human biomedicine as a model. One must question the validity of using human bioethical principlism moral norms for appropriating a responsible marine biotechnology and aquaculture ethic. When considering potential impacts within these disciplines, deference must be given to differing value systems in order to find common ground to advance knowledge and avoid emotive impasses that can hinder the science and its application. The import of bioethical considerations when conducting research and/or production is discussed. This discussion is directed toward applying bioethical principles toward technology used for food, biomedical development (e.g., biopharming), or as model species for advancement of knowledge for human diseases.

  6. Adaptive laboratory evolution -- principles and applications for biotechnology.

    PubMed

    Dragosits, Martin; Mattanovich, Diethard

    2013-07-01

    Adaptive laboratory evolution is a frequent method in biological studies to gain insights into the basic mechanisms of molecular evolution and adaptive changes that accumulate in microbial populations during long term selection under specified growth conditions. Although regularly performed for more than 25 years, the advent of transcript and cheap next-generation sequencing technologies has resulted in many recent studies, which successfully applied this technique in order to engineer microbial cells for biotechnological applications. Adaptive laboratory evolution has some major benefits as compared with classical genetic engineering but also some inherent limitations. However, recent studies show how some of the limitations may be overcome in order to successfully incorporate adaptive laboratory evolution in microbial cell factory design. Over the last two decades important insights into nutrient and stress metabolism of relevant model species were acquired, whereas some other aspects such as niche-specific differences of non-conventional cell factories are not completely understood. Altogether the current status and its future perspectives highlight the importance and potential of adaptive laboratory evolution as approach in biotechnological engineering.

    The joint EU-US Task Force on Environmental Biotechnology held a workshop entitled, 'A Celebration of a Decade of Environmental Biotechnology Exchange Activities' on October 17, 2005 in Brussels, Belgium. This was a fitting venue since Brussels was where the EU-US transatlantic initiative originated. The workshop brought together former trainees who are currently active in the field of environmental biotechnology in order to (1) assess the impact of the past training activities; (2) to promote further collaborations; and (3) to highlight working group and task force activities in this field. Presentations by the early career scientists filled the meeting day (seemore » Appendix I and II for meeting agenda and abstract book, respectively). Task Force members chaired the various sessions. An additional poster session provided an opportunity for more intensive scientific exchange. The day culminated with a formal dinner and gathering of all participants. Agencies supporting the activities included DOE, USDA and NSF. Funds received from the DOE were exhausted and USDA and NSF allowed the Task Force to use unexpended monies (via no cost extensions) to facilitate future fellowship exchange activities. Over the past ten years, there has been a high level of sensitivity for working collaboratively with European colleagues. This philosophy simply pervades each and every activity of the EU-US Task Force. Realistically, this means that there is a careful balance between the US and EU participation in all functions. The Brussels 'Celebration' workshop was no exception. The organizers anticipated funding more former U.S. trainees than actually attended the workshop and raised the necessary funds to accomplish this goal. However, the number of U.S. attendees needed to be tempered since the financial resources for our EU counterparts proved more difficult to obtain. In order to maintain the scholarly and political balance on the program of events, fewer U.S. attendees were

    2009-12-01

    Electron-shuttling compounds (electron shuttles [ESs], or redox mediators) are essential components in intracellular electron transfer, while microbes also utilize self-produced and naturally present ESs for extracellular electron transfer. These compounds assist in microbial energy metabolism by facilitating electron transfer between microbes, from electron-donating substances to microbes, and/or from microbes to electron-accepting substances. Artificially supplemented ESs can create new routes of electron flow in the microbial energy metabolism, thereby opening up new possibilities for the application of microbes to biotechnology processes. Typical examples of such processes include halogenated-organics bioremediation, azo-dye decolorization, and microbial fuel cells. Herein we suggest that ESs can be applied widely to create new microbial biotechnology processes.

    Biotechnology has an increasingly extensive use for military purposes. With the upcoming age of biotechnology, military operations are depending more on biotechnical methods. Judging from the evolving law of the theory of command, the command of biotechnology is feasible and inevitable. The report discusses some basic characteristics of modern theories of command, as well as the mature possibility of the command theory of military biotechnology. The evolution of the command theory is closely associated with the development of military medicine. This theory is expected to achieve successes in wars in an ultramicro, nonlethal, reversible, and merciful way and will play an important role in biotechnological identification and orientation, defense and attack, and the maintenance of fighting powers and biological monitoring. The command of military biotechnology has not become a part of the virtual military power yet, but it is an exigent strategic task to construct and perfect this theory.

    2007-01-01

    The aim of this paper is to stimulate debate on the agency (principal-agent) in health-related biotechnology research. It attempts to answer the following questions: What is health-related biotechnology and biotechnology research? What is an agency? What factors are likely to undermine the principal's capacity to exercise informed consent? When might the principal-agency problem arise? How could the agency in biotechnology transfer be strengthened in Sub-Saharan Africa (SSA)? The transfer of health-related biotechnology to SSA ought to be preceded by research to ascertain the effectiveness of such technologies on population health. In that process, the national ethical review committee (REC), as an agent of every human research subject (principal), ought to ensure that international principles (e.g. beneficence, non-malfeasance, autonomy, justice, dignity, truthfulness and honesty) for human experimentation are observed by biotechnology researchers in order to satisfy moral, ethical and legal requirements. The key factors that undermine principals' sovereignty in exercising their right to informed consent to participate in biotechnology trials are discussed. The paper ends with a list of activities that can strengthen the agency, e.g. legislative requirement that all health-related biotechnology transfer should be preceded by rigorous evaluation; continuous update of the agents knowledge of the contents of the international ethical guidelines; and education of potential and actual principals on their human rights; among others.

    Knowledge and technology transfer to African institutes is an important objective to help achieve the United Nations Millennium Development Goals. Plant biotechnology in particular enables innovative advances in agriculture and industry, offering new prospects to promote the integration and dissemination of improved crops and their derivatives from developing countries into local markets and the global economy. There is also the need to broaden our knowledge and understanding of cassava as a staple food crop. Cassava (Manihot esculenta Crantz) is a vital source of calories for approximately 500 million people living in developing countries. Unfortunately, it is subject to numerous biotic and abiotic stresses that impact on production, consumption, marketability and also local and country economics. To date, improvements to cassava have been led via conventional plant breeding programmes, but with advances in molecular-assisted breeding and plant biotechnology new tools are being developed to hasten the generation of improved farmer-preferred cultivars. In this review, we report on the current constraints to cassava production and knowledge acquisition in Africa, including a case study discussing the opportunities and challenges of a technology transfer programme established between the Mikocheni Agricultural Research Institute in Tanzania and Europe-based researchers. The establishment of cassava biotechnology platform(s) should promote research capabilities in African institutions and allow scientists autonomy to adapt cassava to suit local agro-ecosystems, ultimately serving to develop a sustainable biotechnology infrastructure in African countries.

    PubMed

    Otero, José Manuel; Panagiotou, Gianni; Olsson, Lisbeth

    2007-01-01

    Industrial biotechnology is the conversion of biomass via biocatalysis, microbial fermentation, or cell culture to produce chemicals, materials, and/or energy. Industrial biotechnology processes aim to be cost-competitive, environmentally favorable, and self-sustaining compared to their petrochemical equivalents. Common to all processes for the production of energy, commodity, added value, or fine chemicals is that raw materials comprise the most significant cost fraction, particularly as operating efficiencies increase through practice and improving technologies. Today, crude petroleum represents the dominant raw material for the energy and chemical sectors worldwide. Within the last 5 years petroleum prices, stability, and supply have increased, decreased, and been threatened, respectively, driving a renewed interest across academic, government, and corporate centers to utilize biomass as an alternative raw material. Specifically, bio-based ethanol as an alternative biofuel has emerged as the single largest biotechnology commodity, with close to 46 billion L produced worldwide in 2005. Bioethanol is a leading example of how systems biology tools have significantly enhanced metabolic engineering, inverse metabolic engineering, and protein and enzyme engineering strategies. This enhancement stems from method development for measurement, analysis, and data integration of functional genomics, including the transcriptome, proteome, metabolome, and fluxome. This review will show that future industrial biotechnology process development will benefit tremendously from the precedent set by bioethanol - that enabling technologies (e.g., systems biology tools) coupled with favorable economic and socio-political driving forces do yield profitable, sustainable, and environmentally responsible processes. Biofuel will continue to be the keystone of any industrial biotechnology-based economy whereby biorefineries leverage common raw materials and unit operations to integrate

    Biotechnology is the latest in a series of technological innovations that have revolutionized such fields as agriculture and the health sciences. However, along with the benefits of biotechnology are concerns. For biotechnology's potential to be realized, it must be accepted on public and governmental levels. Although many studies focus on adult consumer attitudes, it will be the students of today who will be the consumers and leaders of tomorrow. Therefore, this study focused on the knowledge, attitudes, and perceptions of college students regarding biotechnology. More than 3,000 undergraduate students were surveyed from a variety of undergraduate courses at Texas A&M University in College Station, Texas during the 1997-1998 academic year. Information sought included students' knowledge regarding recent applications of biotechnology, demographic information, and their agreement or disagreement with statements regarding different aspects and applications of biotechnology. This study found that despite a low awareness or knowledge of biotechnology, students were accepting of specific applications or products of biotechnology. Those applications or products viewed as beneficial without involving animals had the highest acceptance levels. A majority of the students identified mass media as their major source of biotechnology while also indicating a high level of distrust of the media. Students also indicated that biotechnology information is needed and that such information is appropriate for high school students. Relationships between knowledge and attitudes were also investigated. A greater knowledge level correlated with a more favorable view of biotechnology. In addition, relationships between demographic variables such as gender and race were investigated. Individuals who identified themselves as scientists were found more accepting of biotechnology while females in general were found less accepting. Females majoring in education were found to be the least

    Apocarotenoids are natural compounds derived from the oxidative cleavage of carotenoids. Particularly, C13-apocarotenoids are volatile compounds that contribute to the aromas of different flowers and fruits and are highly valued by the Flavor and Fragrance industry. So far, the chemical synthesis of these terpenoids has dominated the industry. Nonetheless, the increasing consumer demand for more natural and sustainable processes raises an interesting opportunity for bio-production alternatives. In this regard, enzymatic biocatalysis and metabolically engineered microorganisms emerge as attractive biotechnological options. The present review summarizes promising bioengineering approaches with regard to chemical production methods for the synthesis of two families of C13-apocarotenoids: ionones/dihydroionones and damascones/damascenone. We discuss each method and its applicability, with a thorough comparative analysis for ionones, focusing on the production process, regulatory aspects, and sustainability.

    Background Reproductive technologies have been extensively debated in the literature. As well, feminist economists, environmentalists, and agriculturalists have generated substantial debate and literature on gender. However, the implications for women of health biotechnologies have received relatively less attention. Surprisingly, while gender based frameworks have been proposed in the context of public health policy, practice, health research, and epidemiological research, we could identify no systematic framework for gender analysis of health biotechnology in the developing world. Discussion We propose sex and gender considerations at five critical stages of health biotechnology research and development: priority setting; technology design; clinical trials; commercialization, and health services delivery. Summary Applying a systematic sex and gender framework to five key process stages of health biotechnology research and development could be a first step towards unlocking the opportunities of this promising science for women in the developing world.

    Strategies for biotechnology must take account of opportunities for research, innovation and business growth. At a regional level, public-private collaborations provide potential for such growth and the creation of centres of excellence. By considering recent progress in areas such as genomics, healthcare diagnostics, synthetic biology, gene editing and bio-digital technologies, opportunities for smart, strategic and specialised investment are discussed. These opportunities often involve convergent or disruptive technologies, combining for example elements of pharma-science, molecular biology, bioinformatics and novel device development to enhance biotechnology and the life sciences. Analytical applications use novel devices in mobile health, predictive diagnostics and stratified medicine. Synthetic biology provides opportunities for new product development and increased efficiency for existing processes. Successful centres of excellence should promote public-private business partnerships, clustering and global collaborations based on excellence, smart strategies and innovation if they are to remain sustainable in the longer term.

  17. Modelling abstraction licensing strategies ahead of the UK's water abstraction licensing reform

    Within England and Wales, river water abstractions are licensed and regulated by the Environment Agency (EA), who uses compliance with the Environmental Flow Indicator (EFI) to ascertain where abstraction may cause undesirable effects on river habitats and species. The EFI is a percentage deviation from natural flow represented using a flow duration curve. The allowable percentage deviation changes with different flows, and also changes depending on an assessment of the sensitivity of the river to changes in flow (Table 1). Within UK abstraction licensing, resource availability is expressed as a surplus or deficit of water resources in relation to the EFI, and utilises the concept of 'hands-off-flows' (HOFs) at the specified flow statistics detailed in Table 1. Use of a HOF system enables abstraction to cease at set flows, but also enables abstraction to occur at periods of time when more water is available. Compliance at low flows (Q95) is used by the EA to determine the hydrological classification and compliance with the Water Framework Directive (WFD) for identifying waterbodies where flow may be causing or contributing to a failure in good ecological status (GES; Table 2). This compliance assessment shows where the scenario flows are below the EFI and by how much, to help target measures for further investigation and assessment. Currently, the EA is reviewing the EFI methodology in order to assess whether or not it can be used within the reformed water abstraction licensing system which is being planned by the Department for Environment, Food and Rural Affairs (DEFRA) to ensure the licensing system is resilient to the challenges of climate change and population growth, while allowing abstractors to meet their water needs efficiently, and better protect the environment. In order to assess the robustness of the EFI, a simple model has been created which allows a number of abstraction, flow and licensing scenarios to be run to determine WFD compliance using the

    During the 40th Annual Meeting of The Toxicology Forum, the current and potential future science, regulations, and politics of agricultural biotechnology were presented and discussed. The meeting session described herein focused on the technology of RNA interference (RNAi) in agriculture. The general process by which RNAi works, currently registered RNAi-based plant traits, example RNAi-based traits in development, potential use of double stranded RNA (dsRNA) as topically applied pesticide active ingredients, research related to the safety of RNAi, biological barriers to ingested dsRNA, recent regulatory RNAi science reviews, and regulatory considerations related to the use of RNAi in agriculture were discussed. Participants generally agreed that the current regulatory framework is robust and appropriate for evaluating the safety of RNAi employed in agricultural biotechnology and were also supportive of the use of RNAi to develop improved crop traits. However, as with any emerging technology, the potential range of future products, potential future regulatory frameworks, and public acceptance of the technology will continue to evolve. As such, continuing dialogue was encouraged to promote education of consumers and science-based regulations. Copyright © 2015 Elsevier Inc. All rights reserved.

  20. Recent Advances in Marine Enzymes for Biotechnological Processes.

    PubMed

    Lima, R N; Porto, A L M

    In the last decade, new trends in the food and pharmaceutical industries have increased concern for the quality and safety of products. The use of biocatalytic processes using marine enzymes has become an important and useful natural product for biotechnological applications. Bioprocesses using biocatalysts like marine enzymes (fungi, bacteria, plants, animals, algae, etc.) offer hyperthermostability, salt tolerance, barophilicity, cold adaptability, chemoselectivity, regioselectivity, and stereoselectivity. Currently, enzymatic methods are used to produce a large variety of products that humans consume, and the specific nature of the enzymes including processing under mild pH and temperature conditions result in fewer unwanted side-effects and by-products. This offers high selectivity in industrial processes. The marine habitat has been become increasingly studied because it represents a huge source potential biocatalysts. Enzymes include oxidoreductases, hydrolases, transferases, isomerases, ligases, and lyases that can be used in food and pharmaceutical applications. Finally, recent advances in biotechnological processes using enzymes of marine organisms (bacterial, fungi, algal, and sponges) are described and also our work on marine organisms from South America, especially marine-derived fungi and bacteria involved in biotransformations and biodegradation of organic compounds. © 2016 Elsevier Inc.

    Cassava is an important subsistence crop grown only in the tropics, and represents a major source of calories for many people in developing countries. Improvements in the areas of resistance to insects and viral diseases, enhanced nutritional qualities, reduced cyanogenic content and modified starch characteristics are urgently needed. Traditional breeding is hampered by the nature of the crop, which has a high degree of heterozygosity, irregular flowering, and poor seed set. Biotechnology has the potential to enhance crop improvement efforts, and genetic engineering techniques for cassava have thus been developed over the past decade. Selectable and scorable markers are critical to efficient transformation technology, and must be evaluated for biosafety, as well as efficiency and cost-effectiveness. In order to facilitate research planning and regulatory submission, the literature on biosafety aspects of the selectable and scorable markers currently used in cassava biotechnology is surveyed. The source, mode of action and current use of each marker gene is described. The potential for toxicity, allergenicity, pleiotropic effects, horizontal gene transfer, and the impact of these on food or feed safety and environmental safety is evaluated. Based on extensive information, the selectable marker genes nptII, hpt, bar/pat, and manA, and the scorable marker gene uidA, all have little risk in terms of biosafety. These appear to represent the safest options for use in cassava biotechnology available at this time.

    During the last half century, biotechnology has contributed to the development of many important new and useful products that have improved our quality of life. To a large extent, these contributions are attributable to advances in cellular and molecular biology that can be traced to the discovery of DNA. What began as a science involved with manipulations of whole organisms has transcended into an ability to influence organisms at the cellular and molecular levels with greater speed, flexibility and precision than ever before. This has produced significantly improved pharmaceutical, textile, diagnostic, and environmental products, to name just a few. Early in this new century, biotechnology research is expected to literally explode with exciting new and promising opportunities. More importantly, biotechnology research in the low gravity environment of space is expected to play a significant part in this biotechnology revolution by expediting the discovery of important new medical, agricultural and environmental products. .

  3. Adaptive laboratory evolution – principles and applications for biotechnology

    PubMed Central

    2013-01-01

    Adaptive laboratory evolution is a frequent method in biological studies to gain insights into the basic mechanisms of molecular evolution and adaptive changes that accumulate in microbial populations during long term selection under specified growth conditions. Although regularly performed for more than 25 years, the advent of transcript and cheap next-generation sequencing technologies has resulted in many recent studies, which successfully applied this technique in order to engineer microbial cells for biotechnological applications. Adaptive laboratory evolution has some major benefits as compared with classical genetic engineering but also some inherent limitations. However, recent studies show how some of the limitations may be overcome in order to successfully incorporate adaptive laboratory evolution in microbial cell factory design. Over the last two decades important insights into nutrient and stress metabolism of relevant model species were acquired, whereas some other aspects such as niche-specific differences of non-conventional cell factories are not completely understood. Altogether the current status and its future perspectives highlight the importance and potential of adaptive laboratory evolution as approach in biotechnological engineering. PMID:23815749

    Concerns about food allergy and its societal growth are intertwined with the growing advances in plant biotechnology. The knowledge of plant genes and protein structures provides the key foundation to understanding biochemical processes that produce food allergy. Biotechnology offers the prospect of producing low-allergen or allergen null plants that could mitigate the allergic response. Modified low-IgE binding variants of allergens could be used as a vaccine to build immunotolerance in sensitive individuals. The potential to introduce new allergens into the food supply by biotechnology products is a regulatory concern. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Pathogenic bacteria have evolved sophisticated strategies to overcome host defences, to interact with the immune system and to interfere with essential host systems. We coin the term 'patho-biotechnology' to describe the exploitation of these valuable traits in biotechnology, medicine and food. This approach shows promise for the development of novel vaccine and drug delivery systems, as well as for the design of more technologically robust and effective probiotic cultures with improved biotechnological and clinical applications. The genetic tractability of Listeria monocytogenes, the availability of the complete genome sequence of this intracellular pathogen, its ability to cope with stress, and its ability to traverse the gastrointestinal tract and induce a strong cellular immune response make L. monocytogenes an ideal model organism for demonstrating the patho-biotechnology concept.

    The biology of planktotrophic larvae of Concholepas concholepas is the main bottleneck towards developing biotechnologies to rear this muricid. Data concerning planktonic larvae development, diets and environmental signals triggering larval settlement and recruitment is scarce. We have begun the study of the molecular and cell biology of embryos, larvae and recruits having as a final goal, the development of appropriate biotechnologies to rear this gastropod. First, an inverse ratio between BuChE and AChE enzyme activities was established. This ratio may be a precise developmental marker for this species. Second, for the first time a phosphoinositide related regulatory pathway is reported in a muricid, opening a new approach to the biotechnological management of larvae. Third, the relation between sulfate in sea water and larval motility was studied. Concentrations below 125 microM sulfate decreases larval motility. The sulfate is incorporated in proteoglycans which participate in different developmental phenomena. Lastly, a genomic Concholepas concholepas DNA sequence, similar to that of a human growth hormone probe was detected. This is very interesting since growth factors are key molecules during development, growth and are involved in food conversion rates in fish and also, in a variety of marine invertebrates.

    Dendrimers, commonly referred to as polymeric trees, offer endless opportunities for biotechnological and biomedical applications. By controlling the type, length, and molecular weight of the core, branches and end groups, respectively, the chemical functionality and topology of dendrimeric archetypes can be customized which further can be applied to achieve required solubility, biodegradability, diagnosis and other applications. Given the physicochemical variability of the dendrimers and their hybrids, this review attempts to discuss a full spectrum of recent advances and strides made by these "perfectly designed structures". An extensive biotech/biomimicry application profiling of dendrimers is provided with focus on complex archetypical designs such as protein biomimicry (angiogenic inhibitors, regenerative hydroxyapatite and collagen) and biotechnology applications. In terms of biotechnological advances, dendrimers have provided distinctive advantages in the fields of biocatalysis, microbicides, artificial lights, mitochondrial function modulation, vaccines, tissue regeneration and repair, antigen carriers and even biosensors. In addition, this review provides overview of the extensive chemo-functionalization opportunities available with dendrimers which makes them a perfect candidate for forming drug conjugates, protein hybrids, bio mimics, lipidic derivatives, metal deposits and nanoconjugates thereby making them the most multifunctional platforms for diverse biotechnological applications.

    Homologous recombination, a central concept in biology, is defined as the exchange of DNA strands between two similar or identical nucleotide sequences. Unfortunately, undergraduate students majoring in biotechnology often experience difficulties in understanding the molecular basis of homologous recombination. In this study, we developed and implemented a 12-week laboratory course for biotechnology undergraduates in which gene targeting in Streptococcus suis was used to facilitate their understanding of the basic concept and process of homologous recombination. Students worked in teams of two to select a gene of interest to create a knockout mutant using methods that relied on homologous recombination. By integrating abstract knowledge and practice in the process of scientific research, students gained hands-on experience in molecular biology techniques while learning about the principle and process of homologous recombination. The learning outcomes and survey-based assessment demonstrated that students substantially enhanced their understanding of how homologous recombination could be used to study gene function. Overall, the course was very effective for helping biotechnology undergraduates learn the theory and application of homologous recombination, while also yielding positive effects in developing confidence and scientific skills for future work in research. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):329-335, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

    The success of biotechnological research, development and marketing depends to a large extent on the international transfer of information and on the ability to organise biotechnology information into knowledge. To increase the efficiency of information-based approaches, an information strategy has been developed and consists of the following stages: definition of the problem, its structure and sub-problems; acquisition of data by targeted processing of computer-supported bibliographic, numeric, textual and graphic databases; analysis of data and building of specialized in-house information systems; information processing for structuring data into systems, recognition of trends and patterns of knowledge, particularly by information synthesis using the concept of information density; design of research hypotheses; testing hypotheses in the laboratory and/or pilot plant; repeated evaluation and optimization of hypotheses by information methods and testing them by further laboratory work. The information approaches are illustrated by examples from the university-industry joint projects in biotechnology, biochemistry and agriculture.

  12. Applications of Protein Hydrolysates in Biotechnology

    Pasupuleti, Vijai K.; Holmes, Chris; Demain, Arnold L.

    By definition, protein hydrolysates are the products that are obtained after the hydrolysis of proteins and this can be achieved by enzymes, acid or alkali. This broad definition encompasses all the products of protein hydrolysis - peptides, amino acids and minerals present in the protein and acid/alkali used to adjust pH (Pasupuleti 2006). Protein hydrolysates contain variable side chains depending on the enzymes used. These side chains could be carboxyl, amino, imidazole, sulfhydryl, etc. and they may exert specific physiological roles in animal, microbial, insect and plant cells. This introductory chapter reviews the applications of protein hydrolysates in biotechnology. The word biotechnology is so broad and for the purpose of this book, we define it as a set of technologies such as cell culture technology, bioprocessing technology that includes fermentations, genetic engineering technology, microbiology, and so on. This chapter provides introduction and leads to other chapters on manufacturing and applications of protein hydrolysates in biotechnology.

    Summary The bulk of the Earth's biosphere is cold (e.g. 90% of the ocean's waters are ≤ 5°C), sustaining a broad diversity of microbial life. The permanently cold environments vary from the deep ocean to alpine reaches and to polar regions. Commensurate with the extent and diversity of the ecosystems that harbour psychrophilic life, the functional capacity of the microorganisms that inhabitat the cold biosphere are equally diverse. As a result, indigenous psychrophilic microorganisms provide an enormous natural resource of enzymes that function effectively in the cold, and these cold‐adapted enzymes have been targeted for their biotechnological potential. In this review we describe the main properties of enzymes from psychrophiles and describe some of their known biotechnological applications and ways to potentially improve their value for biotechnology. The review also covers the use of metagenomics for enzyme screening, the development of psychrophilic gene expression systems and the use of enzymes for cleaning. PMID:21733127

    1994-05-01

    This abstract describes a three-dimensional (3D) finite element solution of a test model that has been reported in the literature. The model is a basis for calculating the current redistribution effects in the end windings of turbogenerators. The aim of the study is to see whether the analytical results of the test model can be found using a general purpose finite element package, thus indicating that the finite element model is accurate enough to treat real end winding problems. The real end winding problems cannot be solved analytically, as the geometry is far too complicated. The model consists of a polyphase coil set, containing 44 individual coils. This set generates a two pole mmf distribution on a cylindrical surface. The rotating field causes eddy currents to flow in the inner massive and conducting rotor. In the analytical solution a perfect sinusoidal mmf distribution is put forward. The finite element model contains 85824 tetrahedra and 16451 nodes. A complex single scalar potential representation is used in the nonconducting parts. The computation time required was 3 h and 42 min. The flux plots show that the field distribution is acceptable. Furthermore, the induced currents are calculated and compared with the values found from the analytical solution. The distribution of the eddy currents is very close to the distribution of the analytical solution. The most important results are the losses, both local and global. The value of the overall losses is less than 2% away from those of the analytical solution. Also the local distribution of the losses is at any given point less than 7% away from the analytical solution. The deviations of the results are acceptable and are partially due to the fact that the sinusoidal mmf distribution was not modeled perfectly in the finite element method.

    Biotechnology-derived products represent a class of increasingly numerous drugs. One of their major characteristics is extreme diversity, which requires specific approaches for the preclinical evaluation of their safety. The selection of relevant animal species is not easy, as most of these products are human-specific. Thus, only one species will often be used, i.e. primates. As most of these products are large molecules, they can be directly immunogenic. When they are human-specific, no animal model is available to predict the risk. Many biotechnology-derived products have an expected influence on the immune system. This must be taken into account in the preclinical strategy of immunotoxicity evaluation that is now required for every new drug. As conventional toxicity testing is generally limited, safety pharmacology studies should include more than the core battery of assays required by current guidelines in order to complement missing data as much as possible. Because of these particularities, a comprehensive investigation of metabolism and pharmacokinetics is not usually needed. Some products can cross-react with cellular components not intended as therapeutic targets. It is, therefore, essential to rule out the risk of possible cross-reactions that can result in adverse effects. Finally, viral safety is a crucial component of the preclinical safety evaluation of these products. Overall, biotechnology-derived products raise specific issues because of their innovative and original characteristics, and it is difficult to address all these issues if not by using a case-by-case approach.

    The Space Biotechnology and Commercial Applications grant was funded by NASA's Kennedy Space Center in FY 2002 to provide dedicated biotechnology and agricultural research focused on the regeneration of space flight environments with direct parallels in Earth-based applications for solving problems in the environment, advances in agricultural science, and other human support issues amenable to targeted biotechnology solutions. This grant had three project areas, each with multiple tasks. They are: 1) Space Agriculture and Biotechnology Research and Education, 2) Integrated Smart Nanosensors for Space Biotechnology Applications, and 3) Commercial Applications. The Space Agriculture and Biotechnology Research and Education (SABRE) Center emphasized the fundamental biology of organisms involved in space flight applications, including those involved in advanced life support environments because of their critical role in the long-term exploration of space. The SABRE Center supports research at the University of Florida and at the Space Life Sciences Laboratory (SLSL) at the Kennedy Space Center. The Integrated Smart Nanosensors for Space Biotechnology Applications component focused on developing and applying sensor technologies to space environments and agricultural systems. The research activities in nanosensors were coordinated with the SABRE portions of this grant and with the research sponsored by the NASA Environmental Systems Commercial Space Technology Center located in the Department of Environmental Engineering Sciences. Initial sensor efforts have focused on air and water quality monitoring essential to humans for living and working permanently in space, an important goal identified in NASA's strategic plan. The closed environment of a spacecraft or planetary base accentuates cause and effect relationships and environmental impacts. The limited available air and water resources emphasize the need for reuse, recycling, and system monitoring. It is essential to

    The abilities of acidophilic chemolithotrophic bacteria and archaea to accelerate the oxidative dissolution of sulfide minerals have been harnessed in the development and application of a biotechnology for extracting metals from sulfidic ores and concentrates. Biomining is currently used primarily to leach copper sulfides and as an oxidative pretreatment for refractory gold ores, though it is also used to recover other base metals, such as cobalt, nickel and zinc. Recent developments have included using acidophiles to process electronic wastes, to extract metals from oxidized ores, and to selectively recover metals from process waters and waste streams. This review describes the microorganisms and mechanisms involved in commercial biomining operations, how the technology has developed over the past 50 years, and discusses the challenges and opportunities for mineral biotechnologies in the 21st century.

    Polyols such as mannitol, erythritol, sorbitol, and xylitol are naturally found in fruits and vegetables and are produced by certain bacteria, fungi, yeasts, and algae. These sugar alcohols are widely used in food and pharmaceutical industries and in medicine because of their interesting physicochemical properties. In the food industry, polyols are employed as natural sweeteners applicable in light and diabetic food products. In the last decade, biotechnological production of polyols by lactic acid bacteria (LAB) has been investigated as an alternative to their current industrial production. While heterofermentative LAB may naturally produce mannitol and erythritol under certain culture conditions, sorbitol and xylitol have been only synthesized through metabolic engineering processes. This review deals with the spontaneous formation of mannitol and erythritol in fermented foods and their biotechnological production by heterofermentative LAB and briefly presented the metabolic engineering processes applied for polyol formation.

  3. Safe and Sound? Scientists’ Understandings of Public Engagement in Emerging Biotechnologies

    2015-01-01

    Science communication is a widely debated issue, particularly in the field of biotechnology. However, the views on the interface between science and society held by scientists who work in the field of emerging biotechnologies are currently insufficiently explored. Therefore filling this gap is one of the urgent desiderata in the further development of a dialogue-oriented model of science-public interaction. Against this background, this article addresses two main questions: (1) How do the persons who work in the field of science perceive the public and its involvement in science? (2) What preferred modes of communication are stressed by those scientists? This research is based on a set of interviews with full professors from the field of biotechnology with a special focus on synthetic biology. The results show that scientists perceive the public as holding a primarily risk-focused view of science. On the one hand, different forms of science communication are thereby either seen as a chance to improve the public acceptance of science in general and one field of research in particular. On the other hand, the exchange with the public is seen as a duty because the whole of society is affected by scientific innovation. Yet, some of the stakeholders’ views discussed here conflict with debates on public engagement in technological innovation. PMID:26660160

    The analysis of patent activity is one methodology used for technological monitoring. In this paper, the activity of biotechnology-related patents in Brazil were analyzed through 30 International Patent Classification (IPC) codes published by the Organization for Economic Cooperation and Development (OECD). We developed a program to analyse the dynamics of the major patent applicants, countries and IPC codes extracted from the Brazilian Patent Office (INPI) database. We also identified Brazilian patent applicants who tried to expand protection abroad via the Patent Cooperation Treaty (PCT). We had access to all patents published online at the INPI from 1975 to July 2010, including 9,791 biotechnology patent applications in Brazil, and 163 PCTs published online at World Intellectual Property Organization (WIPO) from 1997 to December 2010. To our knowledge, there are no other online reports of biotechnology patents previous to the years analyzed here. Most of the biotechnology patents filed in the INPI (10.9%) concerned measuring or testing processes involving nucleic acids. The second and third places belonged to patents involving agro-technologies (recombinant DNA technology for plant cells and new flowering plants, i.e. angiosperms, or processes for obtaining them, and reproduction of flowering plants by tissue culture techniques). The majority of patents (87.2%) were filed by nonresidents, with USA being responsible for 51.7% of all biotechnology patents deposited in Brazil. Analyzing the resident applicants per region, we found a hub in the southeast region of Brazil. Among the resident applicants for biotechnology patents filed in the INPI, 43.5% were from São Paulo, 18.3% were from Rio de Janeiro, and 9.7% were from Minas Gerais. Pfizer, Novartis, and Sanofi were the largest applicants in Brazil, with 339, 288, and 245 biotechnology patents filed, respectively. For residents, the largest applicant was the governmental institution FIOCRUZ (Oswaldo Cruz

    This paper contributes in two ways to the aims of this special issue on abstraction. The first is to show that there are compelling reasons motivating the use of abstraction in the purely computational realm of artificial intelligence. The second is to contribute to the overall discussion of the nature of abstraction by providing examples of the abstraction processes currently used in artificial intelligence. Although each type of abstraction is specific to a somewhat narrow context, it is hoped that collectively they illustrate the richness and variety of abstraction in its fullest sense.

  8. Rational selection of alternative, environmentally compatible surfactants for biotechnological production of pharmaceuticals--a step toward green biotechnology.

    The biotechnological production of pharmaceutical active substances needs ancillary substances. Surfactants are used at the end of the cell culture as a protection against potential viral or bacterial contamination and to lyse the producing cells for isolation and purification of the products. To find a replacement for a surfactant that had raised environmental concern, environmentally relevant data for potential alternatives were searched for in the literature. Significant data gaps were filled with additional tests: biodegradability, algal growth inhibition, acute daphnid immobilization and chronic daphnid reproduction toxicity, acute fish toxicity, and activated sludge respiration inhibition. The results were used to model removal in the wastewater treatment plants (WWTPs) serving 3 biotechnological production sites in the Roche Group. Predicted environmental concentrations (PECs) were calculated using realistic amounts of surfactants and site-specific wastewater fluxes, modeled removals for the WWTPs and dilution factors by the respective receiving waters. Predicted no-effect concentrations (PNECs) were derived for WWTPs and for both fresh and marine receiving waters as the treated wastewater of 1 production site is discharged into a coastal water. This resulted in a spreadsheet showing PECs, PNECs, and PEC ÷ PNEC risk characterization ratios for the WWTPs and receiving waters for all investigated surfactants and all 3 sites. This spreadsheet now serves as a selection support for the biotechnological developers. This risk-based prioritization of surfactants is a step toward green biotechnological production. © 2014 SETAC.

    This paper describes the microgravity biotechnology experiments carried out on the Shuttle/Mir program. Four experiments investigated the growth of protein crystals, and three investigated cellular growth. Many hundreds of protein samples were processed using four different techniques. The objective of these experiments was to determine optimum conditions for the growth of very high quality single crystals to be used for structure determination. The Biotechnology System (BTS) was used to process the three cell growth investigations. The samples processed by these experiments were: bovine chondrocytes, human renal epithelial cells, and human breast cancer cells and endothelial cells. The objective was to determine the unique properties of cell aggregates produced in the microgravity environment.

  10. Biotechnological Applications of Microbial (Per)chlorate Reduction.

    While the microbial degradation of a chloroxyanion-based herbicide was first observed nearly ninety years ago, only recently have researchers elucidated the underlying mechanisms of perchlorate and chlorate [collectively, (per)chlorate] respiration. Although the obvious application of these metabolisms lies in the bioremediation and attenuation of (per)chlorate in contaminated environments, a diversity of alternative and innovative biotechnological applications has been proposed based on the unique metabolic abilities of dissimilatory (per)chlorate-reducing bacteria (DPRB). This is fueled in part by the unique ability of these organisms to generate molecular oxygen as a transient intermediate of the central pathway of (per)chlorate respiration. This ability, along with other novel aspects of the metabolism, have resulted in a wide and disparate range of potential biotechnological applications being proposed, including enzymatic perchlorate detection; gas gangrene therapy; enhanced xenobiotic bioremediation; oil reservoir bio-souring control; chemostat hygiene control; aeration enhancement in industrial bioreactors; and, biogenic oxygen production for planetary exploration. While previous reviews focus on the fundamental science of microbial (per)chlorate reduction (for example see Youngblut et al., 2016), here, we provide an overview of the emerging biotechnological applications of (per)chlorate respiration and the underlying organisms and enzymes to environmental and biotechnological industries.

    2000-10-01

    I also recommend the book to the readers of this Journal to provide a base for discussing these issues with the biology majors you teach and with your colleagues in molecular biology. Schacter clarified many technical and practical issues for me, such as the potential usefulness of generating embryos by somatic cell nuclear transfer and the difference between this process and true cloning. I particularly appreciated the measured evaluation of the current products of genetic engineering--Bt corn, bovine growth hormone, testing for BRCA-1 and -2, and forensic use of DNA fingerprinting. Schacter has not succumbed to the temptation to exaggerate either the success or the dangers of biotechnology, but has pointed out the strengths and weaknesses of the methods as part of her commitment to provide readers with the technical base to make their own judgments if and when the situation arises. The book should provide a welcome antidote to both the hype and the panic surrounding advances in biotechnology.

  15. Biotechnology regulation: is policy transfer an appropriate answer?

    PubMed

    Cárdenas-Gómez, Olga Carolina; Létourneau, Lyne

    2010-01-01

    In the world of biotechnology regulation, one often encounters the suggestion that the legislation of other countries should be consulted. Known as "policy transfer" in the field of public policy analysis, the purpose of such a recommendation is for policymakers to use the experiences of other States as a basis for developing appropriate regulatory frameworks in a timely manner. This paper examines whether policy transfer is relevant as an instrument for biotechnology regulation, and if it is, to what extent. Our analysis uses the example of Assisted Reproductive Technologies (ART), and unfolds according to the following argumentative steps. We will begin by discussing policy transfer as a recognized feature of policymaking in the literature pertaining to public policy analysis. We will then introduce a distinction between the technical dimension of policymaking and its political component. We will refer to "morality policy" as an illustration of policymaking directed toward its political component. We will show that, in the case of morality policy, States have moved away from a policy transfer approach. We will then establish that ART qualifies as morality policy, suggesting that policy transfer is most likely not the optimal policymaking tool for dealing with biotechnology regulation. Moving beyond the issue of ART in order to expand our reasoning to biotechnology regulation as a whole, we will conclude that, although the experiences of other States may be useful, policy transfer does not suffice in terms of informing policymaking in the case of biotechnology advances.

    Aqueous two-phase system (ATPS) has been suggested as a promising separation tool in the biotechnological industry. This liquid-liquid extraction technique represents an interesting advance in downstream processing due to several advantages such as simplicity, rapid separation, efficiency, economy, flexibility and biocompatibility. Up to date, a range of biotechnological products have been successfully recovered from different sources with high yield using ATPS-based strategy. In view of the important potential contribution of the ATPS in downstream processing, this review article aims to provide latest information about the application of ATPS in the recovery of various biotechnological products in the past 7 years (2010-2017). Apart from that, the challenges as well as the possible future work and outlook of the ATPS-based recovery method have also been presented in this review article.

    As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

    Aboard the International Space Station (ISS), the Tissue Culture Medium (TCM) is the bioreactor vessel in which cell cultures are grown. With its two syringe ports, it is much like a bag used to administer intravenous fluid, except it allows gas exchange needed for life. The TCM contains cell culture medium, and when frozen cells are flown to the ISS, they are thawed and introduced to the TCM through the syringe ports. In the Cellular Biotechnology Operations Support System-Fluid Dynamics Investigation (CBOSS-FDI) experiment, several mixing procedures are being assessed to determine which method achieves the most uniform mixing of growing cells and culture medium.

    In the last few years, there has been an intense interest in using microalgal lipids in food, chemical and pharmaceutical industries and cosmetology, while a noteworthy research has been performed focusing on all aspects of microalgal lipid production. This includes basic research on the pathways of solar energy conversion and on lipid biosynthesis and catabolism, and applied research dealing with the various biological and technical bottlenecks of the lipid production process. In here, we review the current knowledge in microalgal lipids with respect to their metabolism and various biotechnological applications, and we discuss potential future perspectives. The committing step in fatty acid biosynthesis is the carboxylation of acetyl-CoA to form malonyl-CoA that is then introduced in the fatty acid synthesis cycle leading to the formation of palmitic and stearic acids. Oleic acid may also be synthesized after stearic acid desaturation while further conversions of the fatty acids (i.e. desaturations, elongations) occur after their esterification with structural lipids of both plastids and the endoplasmic reticulum. The aliphatic chains are also used as building blocks for structuring storage acylglycerols via the Kennedy pathway. Current research, aiming to enhance lipogenesis in the microalgal cell, is focusing on over-expressing key-enzymes involved in the earlier steps of the pathway of fatty acid synthesis. A complementary plan would be the repression of lipid catabolism by down-regulating acylglycerol hydrolysis and/or β-oxidation. The tendency of oleaginous microalgae to synthesize, apart from lipids, significant amounts of other energy-rich compounds such as sugars, in processes competitive to lipogenesis, deserves attention since the lipid yield may be considerably increased by blocking competitive metabolic pathways. The majority of microalgal production occurs in outdoor cultivation and for this reason biotechnological applications face some difficulties

    The biotechnology/materials interaction dates back 3.5 billion years, yet today offers novel challenges for human creativity. The materials cycle practiced by microorganisms is compared to that recently practiced by humans. The processes of the biotechnology materials cycle are biogenesis, bioleaching, biofouling, biocorrosion, biodeterioration, and bioaccumulation. Each process is examined for mechanisms, scale of effect, and opportunity for creative human intervention or utilization. More than 50 of our metallic elements are bio-processed in nature. A like number of biogenic materials have been identified, with some at production rates of trillions of kg per annum (p.a.). Microorganisms can substitute for energy, capital, and labor. Over the eons, microorganisms have gained special attributes that now offer creative humans a new era of partnership in materials processing.

  5. Controversial medical and agri-food biotechnology: a cultivation analysis.

    2002-04-01

    Whether biotechnology is one or several developments is not clear. Once distinctions are required, the question is: Which one prevails? When the good, the bad, and the ugly settle, where do they fall? Evaluation implies distinction, and representation drives attitude. The controversies over biotechnology are fertile ground on which to study these issues. The imports of genetically modified (GM) soya into Europe in 1996-97 and the cloning of Dolly the sheep from adult cells in 1997 changed the symbolic environment for genetic engineering. The ensuing public controversies came to focus mainly on field trials of GM crops and food labeling. This paper will explore the relationship between quality press coverage and public perception, in particular the cultivation of the contrast between "desirable" biomedical (RED) and "undesirable" agri-food (GREEN) biotechnology in Britain. The argument draws on a systematic analysis of the British press coverage of biotechnology from 1973 to 1999 and analysis of public perceptions in 1996 and 1999. The paper concludes that the debate over GM crops and food ingredients fostered the RED-GREEN contrast among the newspaper-reading public, thereby shielding RED biotechnology from public controversy, and ushered in a realignment of the regulatory framework in 2000.

    Basic research has provided a much better understanding of the genetic networks and regulatory hierarchies in plants. To meet the challenges of agriculture, we must be able to rapidly translate this knowledge into generating improved plants. Therefore, in this Review, we discuss advanced tools that are currently available for use in plant biotechnology to produce new products in plants and to generate plants with new functions. These tools include synthetic promoters, 'tunable' transcription factors, genome-editing tools and site-specific recombinases. We also review some tools with the potential to enable crop improvement, such as methods for the assembly and synthesis of large DNA molecules, plant transformation with linked multigenes and plant artificial chromosomes. These genetic technologies should be integrated to realize their potential for applications to pressing agricultural and environmental problems.

    Reproductive biotechnology has manifold applications and includes a great innovation potential in livestock. Due to the global changes the new findings and techniques can aid to meet the future challenges. The use of biotechnology in animal production can guarantee enough high quality food for the whole population. Genetic resources of animals can be preserved via sperm and embryo banking. Early diagnosis of hereditary defects, generation of offspring with predetermined sex and the avoidance of animal transports for breeding employing shipment of frozen embryos will improve animal welfare. A special application is the use of animal models for human assisted reproductive technologies. Therefore, not only in Germany research related to the methodologies in reproductive biotechnology and their improvement need to be supported.

    Agriculture faces many challenges to maximize yields while it is required to operate in an environmentally sustainable manner. In the present study, we analyze the major agricultural challenges identified by European farmers (primarily related to biotic stresses) in 13 countries, namely Belgium, Bulgaria, the Czech Republic, France, Germany, Hungary, Italy, Portugal, Romania, Spain, Sweden, UK and Turkey, for nine major crops (barley, beet, grapevine, maize, oilseed rape, olive, potato, sunflower and wheat). Most biotic stresses (BSs) are related to fungi or insects, but viral diseases, bacterial diseases and even parasitic plants have an important impact on yield and harvest quality. We examine how these challenges have been addressed by public and private research sectors, using either conventional breeding, marker-assisted selection, transgenesis, cisgenesis, RNAi technology or mutagenesis. Both national surveys and scientific literature analysis followed by text mining were employed to evaluate genetic engineering (GE) and non-GE approaches. This is the first report of text mining of the scientific literature on plant breeding and agricultural biotechnology research. For the nine major crops in Europe, 128 BS challenges were identified with 40% of these addressed neither in the scientific literature nor in recent European public research programs. We found evidence that the private sector was addressing only a few of these "neglected" challenges. Consequently, there are considerable gaps between farmer's needs and current breeding and biotechnology research. We also provide evidence that the current political situation in certain European countries is an impediment to GE research in order to address these agricultural challenges in the future. This study should also contribute to the decision-making process on future pertinent international consortia to fill the identified research gaps.

    A key aspect of marine environments is elevated pressure; for example, ∼70% of the ocean is at a pressure of at least 38MPa. Many types of Bacteria and Archaea reside under these high pressures, which drive oceanic biogeochemical cycles and catalyze reactions among rocks, sediments and fluids. Most marine prokaryotes are classified as piezotolerant or as (obligate)-piezophiles with few cultivated relatives. The biochemistry and physiology of these organisms are largely unknown. Recently, high-pressure cultivation technology has been combined with omics and DNA recombination methodologies to examine the physiology of piezophilic marine microorganisms. We are now beginning to understand the adaptive mechanisms of these organisms, along with their ecological functions and evolutionary processes. This knowledge is leading to the further development of high-pressure-based biotechnology. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Fenning, Trevor M; Gershenzon, Jonathan

    2002-07-01

    Wood is almost as important to humanity as food, and the natural forests from which most of it is harvested from are of enormous environmental value. However, these slow-growing forests are unable to meet current demand, resulting in the loss and degradation of forest. Plantation forests have the potential to supply the bulk of humanity's wood needs on a long-term basis, and so reduce to acceptable limits the harvest pressures on natural forests. However, if they are to be successful, plantation forests must have a far higher yield of timber than their natural counterparts, on much shorter rotation times. To achieve this in reasonable time, biotechnology must be applied to the tree-improvement process, for which large increases in public and private capital investment are needed. However, additional obstacles exist in the form of opposition to plantations, some forest ecocertification schemes, and concerns about aspects of forest biotechnology, especially genetic engineering. It is the intention of this article to explain, in detail, why plantation forests are needed to sustainably meet the world's demand for wood, why they are not being developed fast enough, and why the application of biotechnology to tree improvement is essential to speeding up this process.

A deeper exploration of the biodiversity richness and ecophysiological properties of microalgae is crucial for enhancing their use for applicative purposes. After describing the actual biotechnological use of microalgae, we consider the multiple faces of taxonomical, morphological, functional and ecophysiological biodiversity of these organisms, and investigate how these properties could better serve the biotechnological field. Lastly, we propose new approaches to enhancing microalgal growth, photosynthesis, and synthesis of valuable products used in biotechnological fields, mainly focusing on culture conditions, especially light manipulations and genetic modifications.

  1. Considerations for conducting research in agricultural biotechnology.

    2003-06-01

    Science has shown its increased vulnerability because of two recent high-profile articles published in major journals on corn produced through biotechnology: a laboratory report suggesting profound consequences to monarch butterfly populations due to Bt corn pollen and a report suggesting transgenic introgression into Mexican maize. While both studies have been widely regarded as having flawed methodology, publishing these studies has created great consternation in the scientific community, regulatory agencies and the general public. There are roles and responsibilities of scientists, scientific journals, the public media, public agencies, and those who oppose or advocate a specific technology, and serious consequences when those roles and responsibilities go awry. Modern communication may exacerbate the flow of misinformation and easily lead to a decline in public confidence about biotechnology and science. However, common sense tells us that scientific inquiry and the publication and reporting of results should be performed with high standards of ethical behavior, regardless of one's personal perspective on agricultural biotechnology.

    The Center for Global Security Research at Lawrence Livermore National Laboratory convened a workshop on August 19, 2016 to consider “Independent Biotechnology: The Innovation-­Regulation Dilemma”. The topic was motivated by the observation that non-­government funded biotechnology research and development activities have grown and diversified tremendously over the past decade. This sector encompasses a broad range of actors and activities: individuals with private laboratories, community “hackerspaces,” biotechnology incubators, and individual startups. Motivations and aspirations are diverse and include such things as personal curiosity, community education, the invention of new products or services, and even the realization of certain economic, political, ormore » social goals. One driving force is the “democratization” of ever more powerful biological technologies, allowing individual citizens and groups access to capabilities that have traditionally only been available to researchers in universities, research institutes, national laboratories, and large commercial concerns. Another is the rise of alternative financing mechanisms such as “crowdsourcing,” which ostensibly provide greater freedom to innovate, and greater public visibility, but entail looser management oversight and transparency.« less

  3. Microbial ecology to manage processes in environmental biotechnology.

    PubMed

    2006-06-01

    Microbial ecology and environmental biotechnology are inherently tied to each other. The concepts and tools of microbial ecology are the basis for managing processes in environmental biotechnology; and these processes provide interesting ecosystems to advance the concepts and tools of microbial ecology. Revolutionary advancements in molecular tools to understand the structure and function of microbial communities are bolstering the power of microbial ecology. A push from advances in modern materials along with a pull from a societal need to become more sustainable is enabling environmental biotechnology to create novel processes. How do these two fields work together? Five principles illuminate the way: (i) aim for big benefits; (ii) develop and apply more powerful tools to understand microbial communities; (iii) follow the electrons; (iv) retain slow-growing biomass; and (v) integrate, integrate, integrate.

    Lysaght, Tamra; Rosenberger, Philip J., III; Kerridge, Ian

    2006-08-01

    In recent years, ethics has become part of most tertiary biotechnology curricula. There is, however, considerable variation in the extent and manner of ethics education provided to students in different institutions. In addition, the perceived need that students and employers have regarding ethics education, and the aims and expected outcomes of ethics education, are rarely made clear. This research reports the findings of a questionnaire administered to 375 undergraduate biotechnology students from 19 Australian universities to determine their attitudes towards the teaching of ethics. The results suggest that undergraduate biotechnology students generally regard ethics education to be important and that ethics should be included in undergraduate biotechnology curricula. Students tended, however, to emphasize the professional and industrial side of ethics and not to recognize the personal effects of morals and behaviour. We provide suggestions for rethinking how ethics should be taught.

    Owing to peculiar properties of nanobody, including nanoscale size, robust structure, stable and soluble behaviors in aqueous solution, reversible refolding, high affinity and specificity for only one cognate target, superior cryptic cleft accessibility, and deep tissue penetration, as well as a sustainable source, it has been an ideal research tool for the development of sophisticated nanobiotechnologies. Currently, the nanobody has been evolved into versatile research and application tool kits for diverse biomedical and biotechnology applications. Various nanobody-derived formats, including the nanobody itself, the radionuclide or fluorescent-labeled nanobodies, nanobody homo- or heteromultimers, nanobody-coated nanoparticles, and nanobody-displayed bacteriophages, have been successfully demonstrated as powerful nanobiotechnological tool kits for basic biomedical research, targeting drug delivery and therapy, disease diagnosis, bioimaging, and agricultural and plant protection. These applications indicate a special advantage of these nanobody-derived technologies, already surpassing the "me-too" products of other equivalent binders, such as the full-length antibodies, single-chain variable fragments, antigen-binding fragments, targeting peptides, and DNA-based aptamers. In this review, we summarize the current state of the art in nanobody research, focusing on the nanobody structural features, nanobody production approach, nanobody-derived nanobiotechnology tool kits, and the potentially diverse applications in biomedicine and biotechnology. The future trends, challenges, and limitations of the nanobody-derived nanobiotechnology tool kits are also discussed.

    The recent growth of biotechnology requires a wide range of expertise within the industry. Education is the primary platform for students to gain information and knowledge on biotechnology. In Malaysia where biotechnology is relatively new, education programs and courses must be tailored to meet the demands of the industry. A combination of theoretical knowledge as well as practical and industrial training is essential to ensure graduates are prepared for their career in the fields of biotechnology. Results from this study show that university students lack literacy on biotechnology information and access to facilities provided by the universities. This may be a significant contributing factor to the lack of knowledge and information amongst graduates. Furthermore comparative analysis on the biotechnology program in Malaysian universities with that of other countries show the need to restructure the program by offering more specialized courses as well as soft skills and business subjects. This is to meet the demands of the related professionals as well as the various branches that exist in the biotechnology industry. © 2015 The International Union of Biochemistry and Molecular Biology.

    NASA is working with its international partners to develop space vehicles and facilities that will give researchers the opportunity to conduct scientific investigations in space. As part of this activity, NASA's Biotechnology Cell Science Program (BCSP) at the Johnson Space Center (JSC) is developing a world-class biotechnology laboratory facility for the International Space Station (ISS). This report describes the BCSP, including the role of the BTS. We identify the purpose and objectives of the BTS and a detailed description of BTS facility design and operational concept, BTS facility and experiment-specific hardware, and scientific investigations conducted in the facility. We identify the objectives, methods, and results of risk mitigation investigations of the effects of microgravity and cosmic radiation on the BTS data acquisition and control system. These results may apply to many other space experiments that use commercial, terrestrial-based data acquisition technology. Another focal point is a description of the end-to-end process of integrating and operating biotechnology experiments on a variety of space vehicles. The identification of lessons learned that can be applied to future biotechnology experiments is an overall theme of the report. We include a brief summary of the science results, but this is not the focus of the report. The report provides some discussion on the successful 130-day tissue engineering experiment performed in BTS on Mir and describes a seminal gene array investigation that identified a set of unique genes that are activated in space.

    Since 1990s Malaysia aspired to make biotechnology and bioeconomy as her engines of economic growth to utlise the abundance of natural resources and biodiversity. The public sector plays an integral role in developing the sector and various incentives are in place for the private sector to be actively involved and to forge collaboration with the public sector. The country launched its National Biotechnology Policy in 2005 and later launched its National Bioeconomy Programme in 2010 to become the first country in South East Asia and second in Asia after China to have such an initiative. Malaysia is also very proactive in its biosafety law and regulations and has most of the related legal instrument in place. A lot of success has been recorded since the inception of the National Biotechnology Policy in terms of job creation, contribution to GDP through biobusinesses and investment from foreign companies, but the sector is not spared from challenges too. Due to the nature of the discipline that is multidisciplinary and that requires huge amount of investment, expertise and political will, there are a lot of barriers before the country emerges as a bioeconomy player. This paper discusses the public policies, initiatives and funding mechanisms in place in Malaysia that drive its research, development and commercialisation in the area of biotechnology and bioeconomy. The authors also discuss the challenges faced in Malaysia in implementing the policies. Copyright © 2017 Elsevier B.V. All rights reserved.

  14. How Japanese students reason about agricultural biotechnology.

    2004-10-01

    Many have claimed that education of the ethical issues raised by biotechnology is essential in universities, but there is little knowledge of its effectiveness. The focus of this paper is to investigate how university students assess the information given in class to make their own value judgments and decisions relating to issues of agricultural biotechnology, especially over genetically modified organisms (GMOs). Analysis of homework reports related with agricultural biotechnology after identification of key concepts and ideas in each student report is presented. The ideas were sorted into different categories. The ideas were compared with those in the reading materials using the same categories. These categories included: concern about affects on humans, affects on the environment, developing countries and starvation, trust in industry, responsibility of scientists, risk perception, media influence, need for (international) organizations or third parties, and information dissemination. What was consistent through the different years was that more than half of the students took a "neutral" position. A report was scored as "neutral" when the report included both the positive and negative side of an issue, or when the student could not make a definite decision about the use of GMOs and GM food. While it may be more difficult to defend a strong ''for" or "against" position, some students used logical arguments successfully in doing so. Sample comments are presented to depict how Japanese students see agricultural technology, and how they value its application, with comparisons to the general social attitudes towards biotechnology.

    In order to valorize novel biotechnology innovations, there is a need to evaluate ex-ante their market potential. A case in point is biofortification, i.e. the enhancement of the micronutrient content of staple crops through conventional or genetic breeding techniques. In a recent article in Nature Biotechnology, for example, De Steur et al. (2010) demonstrated the large potential consumer health benefits of folate biofortified rice as a means to reduce folate deficiency and Neural-Tube Defects. By focusing on a Chinese high-risk region of Neural-Tube Defects, the current study defines the potential cost-effectiveness of this genetically modified crop where the need to improve folate intake levels is highest. Building on the Disability-Adjusted Life Years (DALY) approach, both the potential health impacts and costs of its implementation are measured and benchmarked against similar innovations. The results show that this transgenic crop could be a highly cost-effective product innovation (US$ 120.34 - US$ 40.1 per DALY saved) to alleviate the large health burden of folate deficiency and reduce the prevalence of neural-tube birth defects. When compared with other biofortified crops and target regions, folate biofortified rice in China has a relatively high health impact and moderate cost-effectiveness. This research further supports the need for, and importance of ex-ante evaluation studies in order to adequately market and, thus, valorize biotechnology innovations. Although the cost-effectiveness analysis enables to illustrate the market potential of innovative agricultural biotechnology research, further research is required to address policy issues on transgenic biofortification, such as biosafety regulatory requirements.

    This mini review describes novel, biotechnology-based, ways of producing the monoterpene limonene. Limonene is applied in relatively highly priced products, such as fragrances, and also has applications with lower value but large production volume, such as biomaterials. Limonene is currently produced as a side product from the citrus juice industry, but the availability and quality are fluctuating and may be insufficient for novel bulk applications. Therefore, complementary microbial production of limonene would be interesting. Since limonene can be derivatized to high-value compounds, microbial platforms also have a great potential beyond just producing limonene. In this review, we discuss the ins and outs of microbial limonene production in comparison with plant-based and chemical production. Achievements and specific challenges for microbial production of limonene are discussed, especially in the light of bulk applications such as biomaterials.

    Bioligninolysis involves living organisms and/or their products in degradation of lignin, which is highly resistant, plant-originated polymer having three-dimensional network of dimethoxylated (syringyl), monomethoxylated (guaiacyl), and non-methoxylated (p-hydroxyphenyl) phenylpropanoid and acetylated units. As a major repository of aromatic chemical structures on earth, lignin bears paramount significance for its removal owing to potential application of bioligninolytic systems in industrial production. Early reports illustrating the discovery and cloning of ligninolytic biocatalysts in fungi was truly a landmark in the field of enzymatic delignification. However, the enzymology for bacterial delignification is hitherto poorly understood. Moreover, the lignin-degrading bacterial genes are still unknown and need further exploration. This review deals with the current knowledge about ligninolytic enzyme families produced by fungi and bacteria, their mechanisms of action, and genetic regulation and reservations, which render them attractive candidates in biotechnological applications.

    2015-01-01

    Biomass derived from marine microalgae and macroalgae is globally recognized as a source of valuable chemical constituents with applications in the agri-horticultural sector (including animal feeds and health and plant stimulants), as human food and food ingredients as well as in the nutraceutical, cosmeceutical, and pharmaceutical industries. Algal biomass supply of sufficient quality and quantity however remains a concern with increasing environmental pressures conflicting with the growing demand. Recent attempts in supplying consistent, safe and environmentally acceptable biomass through cultivation of (macro- and micro-) algal biomass have concentrated on characterizing natural variability in bioactives, and optimizing cultivated materials through strain selection and hybridization, as well as breeding and, more recently, genetic improvements of biomass. Biotechnological tools including metabolomics, transcriptomics, and genomics have recently been extended to algae but, in comparison to microbial or plant biomass, still remain underdeveloped. Current progress in algal biotechnology is driven by an increased demand for new sources of biomass due to several global challenges, new discoveries and technologies available as well as an increased global awareness of the many applications of algae. Algal diversity and complexity provides significant potential provided that shortages in suitable and safe biomass can be met, and consumer demands are matched by commercial investment in product development.

    2015-06-01

    Selenium (Se) is not only a strategic element in high-tech electronics and an essential trace element in living organisms, but also a potential toxin with low threshold concentrations. Environmental biotechnological applications using bacterial biomineralization have the potential not only to remove selenium from contaminated waters, but also to sequester it in a reusable form. Selenium biomineralization has been observed in phylogenetically diverse microorganisms isolated from pristine and contaminated environments, yet it is one of the most poorly understood biogeochemical processes. Microbial respiration of selenium is unique because the microbial cells are presented with both soluble (SeO(4)(2-) and SeO(3)(2-)) and insoluble (Se(0)) forms of selenium as terminal electron acceptor. Here, we highlight selenium biomineralization and the potential biotechnological uses for it in bioremediation and wastewater treatment. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Photosynthetic protists, also called microalgae, have been systematically studied for more than a century. However, only recently broad biotechnological applications have fostered a novel wave of research on their potentialities as sustainable resources of renewable energy as well as valuable industrial and agro-food products. At the recent VII European Congress of Protistology held in Seville, three outstanding examples of different research strategies on microalgae with biotechnological implications were presented, which suggested that integrative approaches will produce very significant advances in this field in the next future. In any case, intense research and the application of systems biology and genetic engineering techniques are absolutely essential to reach the full potential of microalgae as cell-factories of bio-based products and, therefore, could contribute significantly to solve the problems of biosustainability and energy shortage.

    2012-01-01

    In recent years, the land area under agriculture has declined as also has the rate of growth in agricultural productivity while the demand for food continues to escalate. The world population now stands at 7 billion and is expected to reach 9 billion in 2045. A broad range of agricultural genetic diversity needs to be available and utilized in order to feed this growing population. Climate change is an added threat to biodiversity that will significantly impact genetic resources for food and agriculture (GRFA) and food production. There is no simple, all-encompassing solution to the challenges of increasing productivity while conserving genetic diversity. Sustainable management of GRFA requires a multipronged approach, and as outlined in the paper, biotechnologies can provide powerful tools for the management of GRFA. These tools vary in complexity from those that are relatively simple to those that are more sophisticated. Further, advances in biotechnologies are occurring at a rapid pace and provide novel opportunities for more effective and efficient management of GRFA. Biotechnology applications must be integrated with ongoing conventional breeding and development programs in order to succeed. Additionally, the generation, adaptation, and adoption of biotechnologies require a consistent level of financial and human resources and appropriate policies need to be in place. These issues were also recognized by Member States at the FAO international technical conference on Agricultural Biotechnologies for Developing Countries (ABDC-10), which took place in March 2010 in Mexico. At the end of the conference, the Member States reached a number of key conclusions, agreeing, inter alia, that developing countries should significantly increase sustained investments in capacity building and the development and use of biotechnologies to maintain the natural resource base; that effective and enabling national biotechnology policies and science-based regulatory frameworks can

    Undoubtedly, biotechnology has a tremendous impact on our daily lives. As a result of this and in parallel to the advancement of knowledge in this field of applied research, consumer awareness of the potential benefits and risks of this technology has steadily increased, leading to a thorough investigation of the public perception of biotechnology in the past years. Indeed, it has become clear that it is in the general interest of science and especially of applied research to inform the public of its advances. A promising next step is to strengthen biotechnology communication in scholastic institutions. In this paper, we investigate the perception of biotechnology in a specific target group, namely high-school students in the 16-20-year-old age range. We conducted a questionnaire-based survey on a total of 1410 students in six European countries to investigate students' perception, concern, scientific knowledge, and awareness. Our data revealed some unexpected patterns of acceptance and concern about biotechnology. Knowledge analysis indicated that pupils lack specific knowledge about biotechnological applications and their interest in biotechnology appeared to be linked to knowledge. Analysis of specific questions about teaching practices at schools suggests that a better targeted choice in media as vehicles for information together with selected speakers could be instrumental in increasing students' interest in science and more specifically in biotechnology.

    2017-01-01

    Abstract Apple is a fruit crop cultivated worldwide. Apple orchards are exposed to a diverse set of environmental and biological factors that affect the productivity and sustainability of the culture. Many of the efforts and costs for apple production rely on reducing the incidence of fungal diseases, and one of the main diseases is apple scab caused by the fungus Venturia inaequalis. The economic impact of scab on apple productivity has guided many breeding programs to search for cultivars resistant to apple scab. Introgression from wild relatives has been successful to some extent, and genetic engineering for resistant cultivars has even been employed. This review presents the techniques used to the present time to obtain pathogen-resistant apple cultivars and introduces new biotechnological approaches based on plant plasmids that show promising results for delivering genetic traits with a short-term perspective.

For that possibility to synthesize various kind of nanoparticles (NPs) and the ever-increasing ability to control their size as well as structure, to improve surface characteristics and binding NPs with other desired curing agents has played an important role. In this paper, a brief sketch of various kinds of nanomaterials and their biomedical applications is given. Despite claims of bio-nanotechnology about to touch all areas of medical science, information pertaining to the role of nanotechnology for the betterment of reproductive healthcare is indeed limited. Therefore, the various achievements of nano-biotechnology for healthcare in general have been illustrated while giving special insight into the role of nano-biotechnology for the future of reproductive healthcare betterment as well as current achievements of nanoscience and nanotechnology in this arena.

    Given the increasing commercial and clinical relevance of probiotic cultures, improving their stress tolerance profile and ability to overcome the physiochemical defences of the host is an important biological goal. Pathogenic bacteria have evolved sophisticated strategies to overcome host defences, interact with the immune system and interfere with essential host systems. We coin the term 'patho-biotechnology' to describe the exploitation of these valuable traits in biotechnology and biomedicine. This approach shows promise for the design of more technologically robust and effective probiotic cultures with improved biotechnological and clinical applications as well as the development of novel vaccine and drug delivery platforms.

    Both the United States and New Zealand are doing research in forest biotechnology and much of the interest is in speedy propagation from seed to mature tree. A number of propagation techniques are discussed, such as tissue culture, the culture of tissue from mature trees and somatic embryo genesis. Much of the tissue culture work has been done on radiata pine. Field testing results are considered. The aims and the advantages of forest biotechnology are discussed under the following headings. 1) Disease resistance: research is being carried out on a loblolly pine which would be resistant to fusiform rust. 2)more » Animal feed: some trees have been discovered to have lower lignin content and similar cellulose and hemicellulose to alfalfa. 3) Specialty chemicals: terpenes, in the tree resin, could be turned into hormones, drugs and other chemicals: the genetic system for the overall biosynthesis of terpenes has been studied. 4) Herbicide resistance. The resistance to glyphosate in poplars is being studied. In conclusion, further research into forest species, using molecular biology is considered essential.« less

    The impact of biotechnologies on peoples' everyday lives continuously increases. Measuring young peoples' attitudes toward biotechnologies is therefore very important and its results are useful not only for science curriculum developers and policy makers, but also for producers and distributors of genetically modified products. Despite of substantial number of instruments which focused on measuring student attitudes toward biotechnology, a majority of them were not rigorously validated. This study deals with the development and validation of an attitude questionnaire toward biotechnology. Detailed information on development and validation process of the instrument is provided. Data gathered from 326 university students provided evidence for the validity and reliability of the new instrument which consists of 28 attitude items on a five point likert type scale. It is believed that the instrument will serve as a valuable tool for both instructors and researchers in science education to assess students' biotechnology attitudes.

  1. Utilization of protein-rich residues in biotechnological processes.

    2016-03-01

    A drawback of biotechnological processes, where microorganisms convert biomass constituents, such as starch, cellulose, hemicelluloses, lipids, and proteins, into wanted products, is the economic feasibility. Particularly the cost of nitrogen sources in biotechnological processes can make up a large fraction of total process expenses. To further develop the bioeconomy, it is of considerable interest to substitute cost-intensive by inexpensive nitrogen sources. The aim of this mini-review was to provide a comprehensive insight of utilization methods of protein-rich residues, such as fish waste, green biomass, hairs, and food waste. The methods described include (i) production of enzymes, (ii) recovery of bioactive compounds, and/or (iii) usage as nitrogen source for microorganisms in biotechnological processes. In this aspect, the utilization of protein-rich residues, which are conventionally considered as waste, allows the development of value-adding processes for the production of bioactive compounds, biomolecules, chemicals, and materials.

    With the world-wide increase of patients with renal failure, the development of functional renal replacement therapies have gained significant interest and novel technologies are rapidly evolving. Currently used renal replacement therapies insufficiently remove accumulating waste products, resulting in the uremic syndrome. A more preferred treatment option is kidney transplantation, but the shortage of donor organs and the increasing number of patients waiting for a transplant warrant the development of novel technologies. The bioartificial kidney (BAK) is such promising biotechnological approach to replace essential renal functions together with the active secretion of waste products. The development of the BAK requires a multidisciplinary approach and evolves at the intersection of regenerative medicine and renal replacement therapy. Here we provide a concise review embracing a compact historical overview of bioartificial kidney development and highlighting the current state-of-the-art, including implementation of living-membranes and the relevance of extracellular matrices. We focus further on the choice of relevant renal epithelial cell lines versus the use of stem cells and co-cultures that need to be implemented in a suitable device. Moreover, the future of the BAK in regenerative nephrology is discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

  3. Understanding public perceptions of biotechnology through the "Integrative Worldview Framework".

    Biotechnological innovations prompt a range of societal responses that demand understanding. Research has shown such responses are shaped by individuals' cultural worldviews. We aim to demonstrate how the Integrative Worldview Framework (IWF) can be used for analyzing perceptions of biotechnology, by reviewing (1) research on public perceptions of biotechnology and (2) analyses of the stakeholder-debate on the bio-based economy, using the Integrative Worldview Framework (IWF) as analytical lens. This framework operationalizes the concept of worldview and distinguishes between traditional, modern, and postmodern worldviews, among others. Applied to these literatures, this framework illuminates how these worldviews underlie major societal responses, thereby providing a unifying understanding of the literature on perceptions of biotechnology. We conclude the IWF has relevance for informing research on perceptions of socio-technical changes, generating insight into the paradigmatic gaps in social science, and facilitating reflexive and inclusive policy-making and debates on these timely issues. © The Author(s) 2015.

    The PHAR-IN (" Competences for industrial pharmacy practice in biotechnology ") looked at whether there is a difference in how industrial employees and academics rank competences for practice in the biotechnological industry. A small expert panel consisting of the authors of this paper produced a biotechnology competence framework by drawing up an initial list of competences then ranking them in importance using a three-stage Delphi process. The framework was next evaluated and validated by a large expert panel of academics ( n = 37) and industrial employees ( n = 154). Results show that priorities for industrial employees and academics were similar. The competences for biotechnology practice that received the highest scores were mainly in: "Research and Development", '"Upstream" and "Downstream" Processing', "Product development and formulation", "Aseptic processing", "Analytical methodology", "Product stability", and "Regulation". The main area of disagreement was in the category "Ethics and drug safety" where academics ranked competences higher than did industrial employees.

    Computational fluid dynamics (CFD) is well established as a tool of choice for solving problems that involve one or more of the following phenomena: flow of fluids, heat transfer,mass transfer, and chemical reaction. Unit operations that are commonly utilized in biotechnology processes are often complex and as such would greatly benefit from application of CFD. The thirst for deeper process and product understanding that has arisen out of initiatives such as quality by design provides further impetus toward usefulness of CFD for problems that may otherwise require extensive experimentation. Not surprisingly, there has been increasing interest in applying CFD toward a variety of applications in biotechnology processing in the last decade. In this article, we will review applications in the major unit operations involved with processing of biotechnology products. These include fermentation,centrifugation, chromatography, ultrafiltration, microfiltration, and freeze drying. We feel that the future applications of CFD in biotechnology processing will focus on establishing CFD as a tool of choice for providing process understanding that can be then used to guide more efficient and effective experimentation. This article puts special emphasis on the work done in the last 10 years. © 2011 American Institute of Chemical Engineers

    Global meat and milk consumption is exponentially increasing due to population growth, urbanization and changes in lifestyle in the developing world. This is an excellent opportunity for developing countries to improve the livestock sector by using technological advances. Biotechnology is one of the avenues for improved production in the "Livestock revolution". Biotechnology developments applied to livestock health, nutrition, breeding and reproduction are improving with a reasonable pace in developing countries. Simple bio-techniques such as artificial insemination have been well implemented in many parts of the developing world. However, advanced technologies including transgenic plant vaccines, marker assisted selection, solid state fermentation for the production of fibrolytic enzymes, transgenic fodders, embryo transfer and animal cloning are confined largely to research organizations. Some developing countries such as Taiwan, China and Brazil have considered the commercialization of biotechnology in the livestock sector. Organized livestock production systems, proper record management, capacity building, objective oriented research to improve farmer's income, collaborations with the developed world, knowledge of the sociology of an area and research on new methods to educate farmers and policy makers need to be improved for the creation and implementation of biotechnology advances in the livestock sector in the developing world.

    2007-06-01

    Gluconic acid (GA) is a multifunctional carbonic acid regarded as a bulk chemical in the food, feed, beverage, textile, pharmaceutical, and construction industries. The favored production process is submerged fermentation by Aspergillus niger utilizing glucose as a major carbohydrate source, which accompanied product yield of 98%. However, use of GA and its derivatives is currently restricted because of high prices: about US$ 1.20-8.50/kg. Advancements in biotechnology such as screening of microorganisms, immobilization techniques, and modifications in fermentation process for continuous fermentation, including genetic engineering programmes, could lead to cost-effective production of GA. Among alternative carbohydrate sources, sugarcane molasses, grape must show highest GA yield of 95.8%, and banana must may assist reducing the overall cost of GA production. These methodologies would open new markets and increase applications of GA.

    Biotechnological processes are promising alternatives to petrochemical routes for overcoming the challenges of resource depletion in the future in a sustainable way. The strategies of white biotechnology allow the utilization of inexpensive and renewable resources for the production of a broad range of bio-based compounds. Renewable resources, such as agricultural residues or residues from food production, are produced in large amounts have been shown to be promising carbon and/or nitrogen sources. This chapter focuses on the biotechnological production of lactic acid, acrylic acid, succinic acid, muconic acid, and lactobionic acid from renewable residues, these products being used as monomers for bio-based material and/or as food supplements. These five acids have high economic values and the potential to overcome the "valley of death" between laboratory/pilot scale and commercial/industrial scale. This chapter also provides an overview of the production strategies, including microbial strain development, used to convert renewable resources into value-added products.

    Agriculture plays an important role in the national economy of Pakistan, where most of the rapidly increasing population resides in rural areas and depends on agriculture for subsistence. Biotechnology has considerable potential for promoting the efficiency of crop improvement, food production, and poverty reduction. Use of modern biotechnology started in Pakistan since 1985. Currently, there are 29 biotech centers/institutes in the country. However, few centers have appropriate physical facilities and trained manpower to develop genetically modified (GM) crops. Most of the activities have been on rice and cotton, which are among the top 5 crops of Pakistan. Biotic (virus/bacterial/insect) and abiotic (salt) resistant and quality (male sterility) genes have already been incorporated in some crop plants. Despite acquiring capacity to produce transgenic plants, no GM crops, either produced locally or imported, have been released in the country. Pakistan is signatory to the World Trade Organization, Convention on Biological Diversity, and Cartagena protocols. Several legislations under the Agreement on Trade-Related Aspects of Intellectual Property Rights have been promulgated in the country. National Biosafety Guidelines have been promulgated in April 2005. The Plant Breeders Rights Act, Amendment in Seed Act-1976, and Geographical Indication for Goods are still passing through discussion, evaluation, and analysis phases. Meanwhile, an illegal GM crop (cotton) has already sneaked into farmer's field. Concerted and coordinated efforts are needed among various ministries for implementation of regulation and capacity building for import/export and local handling of GM crops. Pakistan could easily benefit from the experience of Asian countries, especially China and India, where conditions are similar and the agriculture sector is almost like that of Pakistan. Thus, the exchange of information and experiences is important among these nations.

    South Asia, once considered as a laggard, has grown at about 6% on average over the past two decades and the current growth outlook is much brighter. However, this growth is not always well distributed and the challenges of institutionalising policies and mechanisms to ensure inclusive growth are now being seriously considered by these countries governments. The targets set by south Asian countries are primarily based on the investments in infrastructural sector with an objective to generate educated and skilled human resources. The other most important inclusive growth area is the core public services; Agriculture, Health, and Energy, which are increasingly becoming technology driven. Biotechnology has been increasingly seen now to be an area of technology that holds the greatest new potential to address problems arising from low productivity, overburdened health systems, high-cost unsustainable energy supplies and the need for developing new materials for industrial and environmental applications. This article attempts to highlight perspectives on some of the emerging areas of biotechnology that have good potential for economic development in the context of south Asia, as well as discuss briefly some of UNESCO's initiatives in biotechnology for that region.

    2012-01-01

    Debate about the potential risks of genetically modified organisms (GMOs) to the environment or human health spurred attention to biosafety. Biosafety is associated with the safe use of GMOs and, more generally, with the introduction of non-indigenous species into natural or managed ecosystems. Biosafety regulation--the policies and procedures adopted to ensure the environmentally safe application of modern biotechnology--has been extensively discussed at various national and international forums. Much of the discussion has focused on developing guidelines, appropriate legal frameworks and, at the international level, a legally binding international biosafety protocol--the Cartagena Protocol on Biosafety. The Protocol is one among various international instruments and treaties that regulate specific aspects relevant to agricultural biotechnology. The present article presents the main international instruments relevant to biosafety regulation, and their key provisions. While international agreements and standards provide important guidance, they leave significant room for interpretation, and flexibility for countries implementing them. Implementation of biosafety at the national level has proven to be a major challenge, particularly in developing countries, and consequently the actual functioning of the international regulatory framework for biotechnology is still in a state of flux.

  8. A new window of opportunity to reject process-based biotechnology regulation

    PubMed Central

    Marchant, Gary E; Stevens, Yvonne A

    2015-01-01

    ABSTRACT. The question of whether biotechnology regulation should be based on the process or the product has long been debated, with different jurisdictions adopting different approaches. The European Union has adopted a process-based approach, Canada has adopted a product-based approach, and the United States has implemented a hybrid system. With the recent proliferation of new methods of genetic modification, such as gene editing, process-based regulatory systems, which are premised on a binary system of transgenic and conventional approaches, will become increasingly obsolete and unsustainable. To avoid unreasonable, unfair and arbitrary results, nations that have adopted process-based approaches will need to migrate to a product-based approach that considers the novelty and risks of the individual trait, rather than the process by which that trait was produced. This commentary suggests some approaches for the design of such a product-based approach. PMID:26930116

    Barley (Hordeum vulgare L.) is one of the founder crops of agriculture, and today it is the fourth most important cereal grain worldwide. Barley is used as malt in brewing and distilling industry, as an additive for animal feed, and as a component of various food and bread for human consumption. Progress in stable genetic transformation of barley ensures a potential for improvement of its agronomic performance or use of barley in various biotechnological and industrial applications. Recently, barley grain has been successfully used in molecular farming as a promising bioreactor adapted for production of human therapeutic proteins or animal vaccines. In addition to development of reliable transformation technologies, an extensive amount of various barley genetic resources and tools such as sequence data, microarrays, genetic maps, and databases has been generated. Current status on barley transformation technologies including gene transfer techniques, targets, and progeny stabilization, recent trials for improvement of agricultural traits and performance of barley, especially in relation to increased biotic and abiotic stress tolerance, and potential use of barley grain as a protein production platform have been reviewed in this study. Overall, barley represents a promising tool for both agricultural and biotechnological transgenic approaches, and is considered an ancient but rediscovered crop as a model industrial platform for molecular farming. © 2013 Elsevier Inc.

    2015-01-01

    Archaea are an understudied domain of life often found in “extreme” environments in terms of temperature, salinity, and a range of other factors. Archaeal proteins, such as a wide range of enzymes, have adapted to function under these extreme conditions, providing biotechnology with interesting activities to exploit. In addition to producing structural and enzymatic proteins, archaea also produce a range of small peptide molecules (such as archaeocins) and other novel secondary metabolites such as those putatively involved in cell communication (acyl homoserine lactones), which can be exploited for biotechnological purposes. Due to the wide array of metabolites produced there is a great deal of biotechnological potential from antimicrobials such as diketopiperazines and archaeocins, as well as roles in the cosmetics and food industry. In this review we will discuss the diversity of small molecules, both peptide and nonpeptide, produced by archaea and their potential biotechnological applications. PMID:26504428

    PubMed

    Hansson, Sven Ove

    2016-08-01

    Precautionary measures to protect human health and the environment should be science based. This implies that they should be directed at a potential danger for which there is credible scientific evidence (although that evidence need not be conclusive). Furthermore, protective measures should be updated as relevant science advances. This means that decisionmakers should be prepared to strengthen the precautionary measures if the danger turns out to be greater than initially suspected, and to reduce or lift them, should the danger prove to be smaller. Most current legislation on agricultural biotechnology has not been scientifically updated. Therefore, it reflects outdated criteria for identifying products that can cause problems. Modern knowledge in genetics, plant biology, and ecology has provided us with much better criteria that risk analysts can use to identify the potentially problematic breeding projects at which precautionary measures should be directed. Legislation on agricultural biotechnology should be scientifically updated. Furthermore, legislators should learn from this example that regulations based on the current state of science need to have inbuilt mechanisms for revisions and adjustments in response to future developments in science. © 2016 Society for Risk Analysis.

    2016-01-01

    ABSTRACT Regulatory policies governing the safety of genetic engineering (rDNA) and the resulting products (GMOs) have been contentious and divisive, especially in agricultural applications of the technologies. These tensions led to vastly different approaches to safety regulation in different jurisdictions, even though the intent of regulations—to assure public and environmental safety—are common worldwide, and even though the international scientific communities agree on the basic principles of risk assessment and risk management. So great are the political divisions that jurisdictions cannot even agree on the appropriate triggers for regulatory capture, whether product or process. This paper reviews the historical policy and scientific implications of agricultural biotechnology regulatory approaches taken by the European Union, USA and Canada, using their respective statutes and regulations, and then critically assesses the scientific underpinnings of each.

    Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced

    Due to its valuable benefits and potential risks, there is a progressing debate among opponents and proponents of biotechnology in recent decades. Previous studies have shown that lack of knowledge about biotechnology remains the concern about genetically modified organisms/food (GMO/GMF). This study assessed levels of educational awareness perceptions and attitudes of United Arab Emirates University (UAEU) students towards biotechnology. An electronic survey including literacy, environmental, social, and economic domains associated with biotechnology was administered to obtain data from undergraduate students in different colleges of the university. Responses from students (n = 1,104) were gathered and statistically analyzed. Results indicated that educational awareness in biotechnology literacy and environmental domains were significantly different according to the enrolled college and the academic achievement of the student. In general, a poor overall performance of our students' understanding was concluded. Aware groups most likely accepted accurate biotechnology information delivered by reliable sources from internet or lectures; they grasped their knowledge from surrounding people as a secondary source. Since UAEU students have several concept misunderstandings of biotechnology and its ethics, our results suggest that awareness plays a crucial role in forming a "clear-cut" opinion about this technology. Because education can shape public attitudes toward biotechnology, priorities on university curricula and teaching strategies should be extensively given, and therefore, improve in respect to this topic. Ultimately, this promotes the students' perception in understanding the new technology. © 2015 The International Union of Biochemistry and Molecular Biology.

    One of the challenges of the Biotechnology industry is keeping up to date with the rapid pace of change and that much of the information, which students learn in their undergraduate studies, will be out of date in a few years. It is therefore crucial that Biotechnology students have the skills to access the relevant information for their studies and critically evaluate the vast volume of information and its sources. By developing information literacy skills, which are part of lifelong learning, Biotechnology graduates are better prepared for their careers. Students also need to understand the issues related to the use of information such as social, political, ethical, and legal implications. This paper will outline the embedding of information literacy skills within the Biotechnology degree at the University of South Australia. Examples of specific activities and their link to assessment will be discussed. Copyright © 2007 International Union of Biochemistry and Molecular Biology, Inc.

  20. Putting concerns about nature in context: the case of agricultural biotechnology.

    PubMed

    Kaebnick, Gregory E

    2007-01-01

    Concerns about nature are playing increasingly prominent roles in a variety of social debates, including medical biotechnology, environmental protection, and agricultural biotechnology. These concerns are often simply rejected as incoherent: critics argue that there is no good account for how natural states of affairs can have moral value, and that the concept of "nature" is too multifarious and vague to be deployed in moral argument anyway. When these concerns are defended, they are frequently formulated as strong claims that make implausible ontological commitments and that ignore the linkages between these different debates. Agricultural biotechnology provides an especially challenging case study for evaluating concerns about nature. I offer a qualified defense that recognizes these concerns as conceptually linked, attends to social context at appropriate points, and overcomes the charges of incoherence. This defense supports a restrained treatment of concerns about nature in public policy: public policy can neither endorse nor dismiss them. In the case of agricultural biotechnology, this stance probably mandates some form of labeling.

  1. Reengineering the retail/ambulatory pharmacy for provision of biotechnology pharmaceutical services.

    PubMed

    Schneider, P J

    1998-07-01

    Biotechnology products offer both problems and opportunities for pharmacists. On one hand, they are expensive to purchase and keep on inventory. Typical compensation for outpatient prescriptions does not offset the cost of maintaining the inventory, or providing the education and training that patients often need to use biotechnology products properly. On the other hand, there are issues related to proper storage, preparation, and administration for which pharmacists are well prepared to address. Pharmacists are also convenient, trusted, and provide service at relatively low cost. Examples of special services that pharmacists can provide to improve the use of biotechnology products include patient education, injection clinics, provision of medical supplies, and predrawing syringes for patients. Patients are often sent to many providers for these services, resulting in inconvenience and fragmentation of care. If new compensation methods can be established to support more comprehensive pharmacy services, the use of biotechnology products by patients will improve.

    Cyanobacteria are considered to be a rich source of novel metabolites of a great importance from a biotechnological and industrial point of view. Some cyanobacterial secondary metabolites (CSMs), exhibit toxic effects on living organisms. A diverse range of these cyanotoxins may have ecological roles as allelochemicals, and could be employed for the commercial development of compounds with applications such as algaecides, herbicides and insecticides. Recently, cyanobacteria have become an attractive source of innovative classes of pharmacologically active compounds showing interesting and exciting biological activities ranging from antibiotics, immunosuppressant, and anticancer, antiviral, antiinflammatory to proteinase-inhibiting agents. A different but not less interesting property of these microorganisms is their capacity of overcoming the toxicity of ultraviolet radiation (UVR) by means of UV-absorbing/screening compounds, such as mycosporine-like amino acids (MAAs) and scytonemin. These last two compounds are true 'multipurpose' secondary metabolites and considered to be natural photoprotectants. In this sense, they may be biotechnologically exploited by the cosmetic industry. Overall CSMs are striking targets in biotechnology and biomedical research, because of their potential applications in agriculture, industry, and especially in pharmaceuticals.

    The order Halanaerobiales contains a number of well-studied halophiles that possess great potential for biotechnological applications. The unique halophilic adaptations that these organisms utilize, such as salting-in mechanisms to increase their intercellular concentration of KCl, combined with their ability to ferment simple sugars, provides an excellent platform for biotechnological development over a wide range of salt levels and possible other extreme conditions, such as alkaline conditions. From fermented foods to oil reservoirs, members of Halanaerobiales are found in many environments. The environmental conditions many of these organisms grow are similar to industrially important processes, such as alkaline pre-treated biomass stocks,more » treatment of crude glycerol from biodiesel production, salty fermented foods, as well as bioremediation of contaminants under extreme conditions of salinity and in some cases, alkalinity. From salt stable enzymes to waste fermentations, bioremediation options, bioenergy, and microbially enhanced oil recovery (MEOR), Halanaerobiales can provide a wide spectrum of environmentally friendly solutions to current problems.« less

    Opinion in Africa over the use of genetically modified crops for food has been divided, honed by more than a decade of arguments in Europe and elsewhere. Fortunately, the perceived image of a passive Africa in this game is changing rapidly with clear positions on how to harness modern biotechnology. This article examines the status of biosafety regulation across Africa, pertinent challenges and the extent to which regulation fosters or constrains the development of agricultural biotechnology.

    PubMed

    Scheitz, Cornelia Johanna Franziska; Peck, Lawrence J; Groban, Eli S

    2018-01-16

    There is a digital revolution taking place and biotechnology companies are slow to adapt. Many pharmaceutical, biotechnology, and industrial bio-production companies believe that software must be developed and maintained in-house and that data are more secure on internal servers than on the cloud. In fact, most companies in this space continue to employ large IT and software teams and acquire computational infrastructure in the form of in-house servers. This is due to a fear of the cloud not sufficiently protecting in-house resources and the belief that their software is valuable IP. Over the next decade, the ability to quickly adapt to changing market conditions, with agile software teams, will quickly become a compelling competitive advantage. Biotechnology companies that do not adopt the new regime may lose on key business metrics such as return on invested capital, revenue, profitability, and eventually market share.

  6. Search and Discovery Strategies for Biotechnology: the Paradigm Shift

    Bull, Alan T.; Ward, Alan C.; Goodfellow, Michael

    2000-01-01

    Profound changes are occurring in the strategies that biotechnology-based industries are deploying in the search for exploitable biology and to discover new products and develop new or improved processes. The advances that have been made in the past decade in areas such as combinatorial chemistry, combinatorial biosynthesis, metabolic pathway engineering, gene shuffling, and directed evolution of proteins have caused some companies to consider withdrawing from natural product screening. In this review we examine the paradigm shift from traditional biology to bioinformatics that is revolutionizing exploitable biology. We conclude that the reinvigorated means of detecting novel organisms, novel chemical structures, and novel biocatalytic activities will ensure that natural products will continue to be a primary resource for biotechnology. The paradigm shift has been driven by a convergence of complementary technologies, exemplified by DNA sequencing and amplification, genome sequencing and annotation, proteome analysis, and phenotypic inventorying, resulting in the establishment of huge databases that can be mined in order to generate useful knowledge such as the identity and characterization of organisms and the identity of biotechnology targets. Concurrently there have been major advances in understanding the extent of microbial diversity, how uncultured organisms might be grown, and how expression of the metabolic potential of microorganisms can be maximized. The integration of information from complementary databases presents a significant challenge. Such integration should facilitate answers to complex questions involving sequence, biochemical, physiological, taxonomic, and ecological information of the sort posed in exploitable biology. The paradigm shift which we discuss is not absolute in the sense that it will replace established microbiology; rather, it reinforces our view that innovative microbiology is essential for releasing the potential of microbial

    Hyperforin is a major active constituent of Hypericum perforatum (St. John's wort). It has amazing pharmacological activities, such as antidepressant properties, but it is labile and difficult to synthesize. Its sensitivity and lipophilicity are challenges for processing and formulation. Its chemical complexity provokes approaches of biotechnological production and modification. Dedifferentiated H. perforatum cell cultures lack appropriate storage sites and hence appreciable hyperforin levels. Shoot cultures are capable of forming hyperforin but less suitable for biomass up-scaling in bioreactors. Roots commonly lack hyperforin but a recently established adventitious root line has been demonstrated to produce hyperforin and derivatives at promising levels. The roots also contained lupulones, the typical constituents of hop (Humulus lupulus). Although shear-sensitive, these root cultures provide a potential production platform for both individual compounds and extracts with novel combinations of constituents and pharmacological activities. Besides in vitro cultivation techniques, the reconstruction of hyperforin biosynthesis in microorganisms is a promising alternative for biotechnological production. The biosynthetic pathway is under study, with omics-technologies being increasingly implemented. These biotechnological approaches may not only yield hyperforin at reasonable productivity but also allow for modifications of its chemical structure and pharmacological profile.

    Cellulase (CEL) presently constitutes a major group of industrial enzyme based on its diverse ranges of utilization. Apart from such current and well-established applications-as in cotton processing, paper recycling, detergent formulation, juice extraction, and animal feed additives-their uses in agricultural biotechnology and bioenergy have been exploited. Supplementation of CELs to accelerate decomposition of plant residues in soil results in improved soil fertility. So far, applying CELs/antagonistic cellulolytic fungi to crops has shown to promote plant growth performance, including enhanced seed germination and protective effects. Their actions are believed mainly to trigger plant defense mechanisms and/or to act as biocontrol agents that mediate disease suppression. However, the exact interaction between the enzymes/fungi and plants has not been clearly elucidated. Under mild conditions, removal of plant cell wall polysaccharides by CELs for protoplast preparation results in reduced protoplast damage and increased viability and yields. CELs have recently shown great potential in enzyme aid extraction of bioactive compounds from plant materials before selective extraction through enhancing release of target molecules, especially those associated with the wall matrix. To date, attempts have been made to formulate CEL preparation for cellulosic-based bioethanol production. The high cost of CELs has created a bottleneck, resulting in an uneconomic production process. The utilization of low-cost carbohydrates, strain improvement, and gene manipulations has been alternatively aimed at reducing the cost of CEL production. In this review, we focus on and discuss current knowledge of CELs and their applications in agriculture, biotechnology, and bioenergy.

    PubMed

    2016-06-01

    Dehydration of yeast cells causes them to enter a state of anhydrobiosis in which their metabolism is temporarily and reversibly suspended. This unique state among organisms is currently used in the production of active dry yeasts, mainly used in baking and winemaking. In recent decades non-conventional applications of yeast dehydration have been proposed for various modern biotechnologies. This mini-review briefly summarises current information on the application of dry yeasts in traditional and innovative fields. It has been shown that dry yeast preparations can be used for the efficient protection, purification and bioremediation of the environment from heavy metals. The high sorption activity of dehydrated yeasts can be used as an interesting tool in winemaking due to their effects on quality and taste. Dry yeasts are also used in agricultural animal feed. Another interesting application of yeast dehydration is as an additional stage in new methods for the stable immobilisation of microorganisms, especially in cases when biotechnologically important strains have no affinity with the carrier. Such immobilisation methods also provide a new approach for the successful conservation of yeast strains that are very sensitive to dehydration. In addition, the application of dehydration procedures opens up new possibilities for the use of yeast as a model system. Separate sections of this review also discuss possible uses of dry yeasts in biocontrol, bioprotection and biotransformations, in analytical methods as well as in some other areas.

The new wave of genomic tools and products (e.g., CRISPR, gene drives, RNAi, synthetic biology, and genetically modified [GM] insects and fish), provide a particularly useful opportunity to reflect on and revise agricultural biotechnology governance. In response, we present five essential features to advance more socially responsible forms of governance. In presenting these, we hope to stimulate further debate and action towards improved forms of governance, particularly as these new genomic tools and products continue to emerge. PMID:27144921

    Some fundamental biotechnologies hold unprecedented potential to eradicate many incurable diseases. However, in absence of regulations, the power of patent makes the future use of some important biotechnology in few institution's hands. The excessive patents restrict researcher access to the fundamental technologies. It generates concerns and complaints of deteriorating the public health and social welfare. Furthermore, intellectual curiosities, funding, respect among colleagues etc., rather than patents, are the real motivations driving a major ground-breaking discoveries in biotechnology. These phenomena reveal that some biotechnology patents are alienated from the purpose of patent system. Therefore, it is necessary to take some approaches to stop over-patenting these fundamental biotechnology inventions. This article proposes a model regulatory framework for controlling biotechnology patent alienating from the purpose of patent system.

    Unique financial challenges faced by biotechnology companies developing therapeutics have contributed to the creation of a highly sensitive market, where stock prices are capable of great fluctuation. The potential for significant financial reward and the nature of the scientific review process make this industry susceptible to illegal share trading on nonpublic information. We examined stock prices of biotechnology products before and after announcement of Phase III clinical trial and Food and Drug Administration (FDA) Advisory Panel results for indirect evidence of insider trading. Biotechnology stock prices were recorded for 98 products undergoing Phase III clinical trials and 49 products undergoing FDA Advisory Panel review between 1990 and 1998. Prices were recorded for 120 consecutive trading days before and after public announcement of these two events. We compared the average change in stock price of successful products ('winners') with unsuccessful products ('losers') before the public announcement of results for both critical events. The difference between average stock price change from 120 to 3 days before public announcement of results of Phase III clinical trial winners (+27%) and losers (-4%) was highly significant (P = 0.0007). A similar but non-significant difference was observed between the average stock price of winning (+27%) and losing products (+13%) before FDA Advisory Panel review announcements (P = 0.25). Our results provide indirect evidence that insider trading may be common in the biotechnology industry. Clinical investigators may wish to consider this issue before participating in any equity position in the biotechnology industry, especially if they are going to perform research for those companies.

    Current research is demonstrating that model-checking and other forms of automated finite-state verification can be effective for checking properties of software systems. Due to the exponential costs associated with model-checking, multiple forms of abstraction are often necessary to obtain system models that are tractable for automated checking. The Bandera Tool Set provides multiple forms of automated support for compiling concurrent Java software systems to models that can be supplied to several different model-checking tools. In this paper, we describe the foundations of Bandera's data abstraction mechanism which is used to reduce the cardinality (and the program's state-space) of data domains in software to be model-checked. From a technical standpoint, the form of data abstraction used in Bandera is simple, and it is based on classical presentations of abstract interpretation. We describe the mechanisms that Bandera provides for declaring abstractions, for attaching abstractions to programs, and for generating abstracted programs and properties. The contributions of this work are the design and implementation of various forms of tool support required for effective application of data abstraction to software components written in a programming language like Java which has a rich set of linguistic features.

    2016-01-01

    The biotechnology segment of the overall biopharma industry has existed for only about 40–45 years, as a driver of new product development. This driving force was initiated with the FDA approval of recombinant human insulin in 1982, originating from the Genentech company. The pharma industry in the early years of 1970s and 1980s engaged with biotechnology companies only to a small extent with their in-licensing of a few recombinant molecules, led by Roche, Eli Lilly, and Johnson and Johnson. However, subsequently and dramatically over the last 25 years, biotechnology has become a primary driver of product and technology innovation and has become a cornerstone in new product development by all biopharma companies. This review demonstrates these evolutionary changes regarding approved products, product pipelines, novelty of the products, FDA approval rates, product sales, financial R&D investments in biotechnology, partnerships, mergers and acquisitions, and patent issues. We now have about 300 biotechnology products approved in USA covering 16 medical disciplines and about 250 indications, with the engagement of 25 pharma companies, along with their biotechnology company innovators and partners. The biotechnology pipeline involves over 1000 molecules in clinical trials, including over 300 molecules associated with the top 10 pharma companies. Product approval rates by the FDA for biotechnology products are over double the rate for drugs. Yes, the R&D paradigm has changed with biotechnology now as one of the major focuses for new product development with novel molecules by the whole biopharma industry.

The goal is to develop procedures that are both convenient for the flight crew and are optimal in providing uniform and reproducible mixing of all components, including cells. The average bead density in a well mixed TCM will be uniform, with no bubbles, and it will be measured using the absorption of light.

    The aim of this article is to review how yeast has contributed to contemporary biotechnology and to seek underlying principles relevant to its future exploitation for human benefit. Recent advances in systems biology combined with new knowledge of genome diversity promise to make yeast the eukaryotic workhorse of choice for production of everything from probiotics and pharmaceuticals to fuels and chemicals. The ability to engineer new capabilities through introduction of controlled diversity based on a complete understanding of genome complexity and metabolic flux is key. Here, we briefly summarise the history that has led to these apparently simple organisms being employed in such a broad range of commercial applications. Subsequently, we discuss the likely consequences of current yeast research for the future of biotechnological innovation.

  6. Complex mediascapes, complex realities: critically engaging with biotechnology debates in Ghana

    PubMed Central

    2018-01-01

    ABSTRACT The recent increase in research and commercialization of genetically modified (GM) crops in Africa has resulted in considerable and understandable interest from farmers, scholars, and practitioners. However, messy situations are often hard to critically engage in from afar, and the recent article published by Braimah et al. [(2017). Debated agronomy: Public discourse and the future of biotechnology policy in Ghana. Global Bioethics. doi:10.1080/11287462.2016.1261604] presents certain claims that further obfuscate – rather than clarify – an already complex landscape. In this commentary I first seek to clarify particular details of the Ghanaian “GMO” (as GM crops are colloquially called in Ghana) story with particular focus on certain actors and their stances. Next, I highlight some methodological shortcomings of Debated Agronomy and correct certain dubious quotations and claims. Finally, I suggest a more ethnographically and discourse-focused methodology to gain much needed insight into how Ghanaians are actively molding, contesting, and questioning GM discourse, funding, and use.

    Parte, S; Sirisha, V L; D'Souza, J S

    Diversity is the hallmark of all life forms that inhabit the soil, air, water, and land. All these habitats pose their unique inherent challenges so as to breed the "fittest" creatures. Similarly, the biodiversity from the marine ecosystem has evolved unique properties due to challenging environment. These challenges include permafrost regions to hydrothermal vents, oceanic trenches to abyssal plains, fluctuating saline conditions, pH, temperature, light, atmospheric pressure, and the availability of nutrients. Oceans occupy 75% of the earth's surface and harbor most ancient and diverse forms of organisms (algae, bacteria, fungi, sponges, etc.), serving as an excellent source of natural bioactive molecules, novel therapeutic compounds, and enzymes. In this chapter, we introduce enzyme technology, its current state of the art, unique enzyme properties, and the biocatalytic potential of marine algal, bacterial, fungal, and sponge enzymes that have indeed boosted the Marine Biotechnology Industry. Researchers began exploring marine enzymes, and today they are preferred over the chemical catalysts for biotechnological applications and functions, encompassing various sectors, namely, domestic, industrial, commercial, and healthcare. Next, we summarize the plausible pros and cons: the challenges encountered in the process of discovery of the potent compounds and bioactive metabolites such as biocatalysts/enzymes of biomedical, therapeutic, biotechnological, and industrial significance. The field of Marine Enzyme Technology has recently assumed importance, and if it receives further boost, it could successfully substitute other chemical sources of enzymes useful for industrial and commercial purposes and may prove as a beneficial and ecofriendly option. With appropriate directions and encouragement, marine enzyme technology can sustain the rising demand for enzyme production while maintaining the ecological balance, provided any undesired exploitation of the marine

    1998-01-01

    Abstracts of scientific papers and posters that are presented at annual scientific meetings of professional societies are part of the broader category of conference literature. They are an important avenue for the dissemination of current data. While timely and succinct, these abstracts present problems such as an abbreviated peer review and incomplete bibliographic access. METHODS: Seventy societies of health sciences professionals were surveyed about the publication of abstracts from their annual meetings. Nineteen frequently cited journals also were contacted about their policies on the citation of meeting abstracts. Ten databases were searched for the presence of meetings abstracts. RESULTS: Ninety percent of the seventy societies publish their abstracts, with nearly half appearing in the society's journal. Seventy-seven percent of the societies supply meeting attendees with a copy of each abstract, and 43% make their abstracts available in an electronic format. Most of the journals surveyed allow meeting abstracts to be cited. Bibliographic access to these abstracts does not appear to be widespread. CONCLUSIONS: Meeting abstracts play an important role in the dissemination of scientific knowledge. Bibliographic access to meeting abstracts is very limited. The trend toward making meeting abstracts available via the Internet has the potential to give a broader audience access to the information they contain. PMID:9549015

    2011-07-01

    This study examined preservice teachers' understanding of biotechnology and its related processes. A sample comprised 88 elementary education preservice teachers at a large university in the Midwest of the USA. A total of 60 and 28 of the participants were enrolled in introductory and advanced science methods courses, respectively. Most participants had taken two integrated science courses at the college level. Data were collected using a questionnaire, which had open-ended items and which required participants to write the definitions and examples of the following terms: biotechnology, genetic engineering, cloning and genetically modified foods. The results indicate that preservice teachers had limited understanding of biotechnology and its related processes. The majority of the preservice teachers provided poor definitions, explanations, and examples of biotechnology, genetic engineering and genetically modified foods. Surprisingly, however, a moderate number of preservice teachers correctly defined cloning and provided correct examples of cloning. Implications for science teacher education, science curriculum, as well as recommendations for further research are discussed. Copyright © 2011 Wiley Periodicals, Inc.

  16. Regulation of animal biotechnology: research needs.

    2007-09-01

    Livestock that result from biotechnology have been a part of agricultural science for over 30 years but have not entered the market place as food or fiber. Two biotechnologies are at the forefront as challenges to the world's systems for regulating the market place: animal clones and transgenic animals. Both technologies have come before the Food and Drug Administration in the United States and it appears that action is imminent for clones. The FDA has asserted principles for evaluation of clones and asserts that "... remaining hazard(s) from cloning are likely to be subtle in nature." The science-based principles recognize that in some areas related to developmental biology and gene expression in clones, additional scientific information would be useful. The role of science then is to use the genomic tools that we have available to answer questions about epigenetic regulation of development and reprogramming of genes to the state found in germ cells. Transgenics pose additional challenges to regulators. If the transgenics are produced using cloning from modified cells then the additional scientific information needed will be related to the effects of insertion and expression of the transgenes. Other approaches such as retrovirally vectored transgenesis will elicit additional questions. These questions will be challenging because the science will have to be related to the expression and function of each gene or class of genes. For the promises of animal biotechnology to be fulfilled, scientists will have to resolve many questions for regulators and the public but tools to answer those questions are rapidly becoming available.

  17. Biotechnology entrepreneurship and ethics: principles, paradigms, and products.

    Kuszler, Patricia C

    2006-09-01

    Biotechnology, whether in the context of new drugs derived from DNA and genetic technology, genetically modified food, or biologics making use of living cells, raises ethical concerns at a variety of different levels. At the research level, there is concern that the very nature of research is being subverted, rather than enhanced, by entrepreneurship. This area of ethical concern has intensified in the United States as a result of the conflicts of interests resulting from the growing alliance between University academia and private industry in the research enterprise. As we travel down the research path into development of a drug or technology, ethical questions arise with respect to protecting human subjects and society from danger and exploitation by researchers. As development gives way to marketing and dissemination of a new product, government regulators are pressed to get drugs and biologics through the regulatory pipeline into the market faster, walking an ethical tightrope between speed and safety. As new biotechnology products enter the market place, doctors and patients traverse yet another tightrope, that between unknown risk and the promise of benefit. And finally, patent protection is increasingly viewed as a unethical culprit in keeping prices high and depriving the global poor from lifesaving drugs and biologics. Bioethics has, to date, been largely a creation of Western research and medicine. As such it is wholly inadequate to respond to the cascade of ethical issues that flow from a vibrant biotechnology industry. And if biotechnology is in its infancy, as most believe, it is crucial that scientists, entrepreneurs and governments engage in dialogue about the ethical and societal questions raised on the road of scientific progress.

  18. Plant biotechnology patents: applications in agriculture and medicine.

    PubMed

    Hefferon, Kathleen

    2010-06-01

    Recent advances in agricultural biotechnology have enabled the field of plant biology to move forward in great leaps and bounds. In particular, recent breakthroughs in molecular biology, plant genomics and crop science have brought about a paradigm shift of thought regarding the manner by which plants can be utilized both in agriculture and in medicine. Besides the more well known improvements in agronomic traits of crops such as disease resistance and drought tolerance, plants can now be associated with topics as diverse as biofuel production, phytoremediation, the improvement of nutritional qualities in edible plants, the identification of compounds for medicinal purposes in plants and the use of plants as therapeutic protein production platforms. This diversification of plant science has been accompanied by the great abundance of new patents issued in these fields and, as many of these inventions approach commercial realization, the subsequent increase in agriculturally-based industries. While this review chapter is written primarily for plant scientists who have great interest in the new directions being taken with respect to applications in agricultural biotechnology, those in other disciplines, such as medical researchers, environmental scientists and engineers, may find significant value in reading this article as well. The review attempts to provide an overview of the most recent patents issued for plant biotechnology with respect to both agriculture and medicine. The chapter concludes with the proposal that the combined driving forces of climate change, as well as the ever increasing needs for clean energy and food security will play a pivotal role in leading the direction for applied plant biotechnology research in the future.

  19. Plastid biotechnology for crop production: present status and future perspectives

    2012-01-01

    The world population is expected to reach an estimated 9.2 billion by 2050. Therefore, food production globally has to increase by 70% in order to feed the world, while total arable land, which has reached its maximal utilization, may even decrease. Moreover, climate change adds yet another challenge to global food security. In order to feed the world in 2050, biotechnological advances in modern agriculture are essential. Plant genetic engineering, which has created a new wave of global crop production after the first green revolution, will continue to play an important role in modern agriculture to meet these challenges. Plastid genetic engineering, with several unique advantages including transgene containment, has made significant progress in the last two decades in various biotechnology applications including development of crops with high levels of resistance to insects, bacterial, fungal and viral diseases, different types of herbicides, drought, salt and cold tolerance, cytoplasmic male sterility, metabolic engineering, phytoremediation of toxic metals and production of many vaccine antigens, biopharmaceuticals and biofuels. However, useful traits should be engineered via chloroplast genomes of several major crops. This review provides insight into the current state of the art of plastid engineering in relation to agricultural production, especially for engineering agronomic traits. Understanding the bottleneck of this technology and challenges for improvement of major crops in a changing climate are discussed. PMID:21437683

    Cavaliere, Matteo; Feng, Song; Soyer, Orkun S.

    2017-01-01

    Summary Microbial communities are increasingly utilized in biotechnology. Efficiency and productivity in many of these applications depends on the presence of cooperative interactions between members of the community. Two key processes underlying these interactions are the production of public goods and metabolic cross‐feeding, which can be understood in the general framework of ecological and evolutionary (eco‐evo) dynamics. In this review, we illustrate the relevance of cooperative interactions in microbial biotechnological processes, discuss their mechanistic origins and analyse their evolutionary resilience. Cooperative behaviours can be damaged by the emergence of ‘cheating’ cells that benefit from the cooperative interactions but do not contribute to them. Despite this, cooperative interactions can be stabilized by spatial segregation, by the presence of feedbacks between the evolutionary dynamics and the ecology of the community, by the role of regulatory systems coupled to the environmental conditions and by the action of horizontal gene transfer. Cooperative interactions enrich microbial communities with a higher degree of robustness against environmental stress and can facilitate the evolution of more complex traits. Therefore, the evolutionary resilience of microbial communities and their ability to constraint detrimental mutants should be considered to design robust biotechnological applications. PMID:28447371

    2016-10-01

    Lignocellulosic biomasses, either from non-edible plants or from agricultural residues, stock biomacromolecules that can be processed to produce both energy and bioproducts. Therefore, they become major candidates to replace petroleum as the main source of energy. However, to shift the fossil-based economy to a bio-based one, it is imperative to develop robust biotechnologies to efficiently convert lignocellulosic streams in power and platform chemicals. Although most of the biomass processing facilities use celluloses and hemicelluloses to produce bioethanol and paper, there is no consolidated bioprocess to produce valuable compounds out of lignin at industrial scale available currently. Usually, lignin is burned to provide heat or it remains as a by-product in different streams, thus arising environmental concerns. In this way, the biorefinery concept is not extended to completion. Due to Nature offers an arsenal of biotechnological tools through microorganisms to accomplish lignin valorization or degradation, an increasing number of projects dealing with these tasks have been described recently. In this review, outstanding reports over the last 6 years are described, comprising the microbial utilization of lignin to produce a variety of valuable compounds as well as to diminish its ecological impact. Furthermore, perspectives on these topics are given.

    Endophytes are microorganisms that colonize the interior of host plants without causing apparent disease. They have been widely studied for their ability to modulate relationships between plants and biotic/abiotic stresses, often producing valuable secondary metabolites that can affect host physiology. Owing to the advantages of microbial fermentation over plant/cell cultivation and chemical synthesis, endophytic fungi have received significant attention as a mean for secondary metabolite production. This article summarizes currently reported results on plant-endophyte interaction hypotheses and highlights the biotechnological applications of endophytic fungi and their metabolites in agriculture, environment, biomedicine, energy, and biocatalysts. Current bottlenecks in industrial development and commercial applications as well as possible solutions are also discussed.

    Microscopic algae and cyanobacteria are excellent sources of numerous compounds, from raw biomass rich in proteins, oils, and antioxidants to valuable secondary metabolites with potential medical use. In the former Czechoslovakia, microalgal biotechnology developed rapidly in the 1960s with the main aim of providing industrial, high-yield sources of algal biomass. Unique cultivation techniques that are still in use were successfully developed and tested. Gradually, the focus changed from bulk production to more sophisticated use of microalgae, including production of bioactive compounds. Along the way, better understanding of the physiology and cell biology of productive microalgal strains was achieved. Currently, microalgae are in the focus again, mostly as possible sources of bioactive compounds and next-generation biofuels for the 21st century.

    Aboard the International Space Station (ISS), the Tissue Culture Module (TCM) is the stationary bioreactor vessel in which cell cultures grow. However, for the Cellular Biotechnology Operations Support Systems-Fluid Dynamics Investigation (CBOSS-FDI), color polystyrene beads are used to measure the effectiveness of various mixing procedures. Uniform mixing is a crucial component of CBOSS experiments involving the immune response of human lymphoid cell suspensions. In this picture, the beads are trapped in the injection port shortly after injection. Swirls of beads indicate, event to the naked eye, the contents of the TCM are not fully mixed. The beads are similar in size and density to human lymphoid cells. The goal is to develop procedures that are both convenient for the flight crew and are optimal in providing uniform and reproducible mixing of all components, including cells. The average bead density in a well mixed TCM will be uniform, with no bubbles, and it will be measured using the absorption of light

    Latest FAO figures indicate that an estimated 925 million people are undernourished in 2010, representing almost 16% of the population in developing countries. Looking to the future, there are also major challenges ahead from the rapidly changing socio-economic environment (increasing world population and urbanisation, and dietary changes) and climate change. Promoting agriculture in developing countries is the key to achieving food security, and it is essential to act in four ways: to increase investment in agriculture, broaden access to food, improve governance of global trade, and increase productivity while conserving natural resources. To enable the fourth action, the suite of technological options for farmers should be as broad as possible, including agricultural biotechnologies. Agricultural biotechnologies represent a broad range of technologies used in food and agriculture for the genetic improvement of plant varieties and animal populations, characterisation and conservation of genetic resources, diagnosis of plant or animal diseases and other purposes. Discussions about agricultural biotechnology have been dominated by the continuing controversy surrounding genetic modification and its resulting products, genetically modified organisms (GMOs). The polarised debate has led to non-GMO biotechnologies being overshadowed, often hindering their development and application. Extensive documentation from the FAO international technical conference on Agricultural Biotechnologies in Developing Countries (ABDC-10), that took place in Guadalajara, Mexico, on 1-4 March 2010, gave a very good overview of the many ways that different agricultural biotechnologies are being used to increase productivity and conserve natural resources in the crop, livestock, fishery, forestry and agro-industry sectors in developing countries.

    Ascomycete yeasts are metabolically diverse, with great potential for biotechnology. Here, we report the comparative genome analysis of 29 taxonomically and biotechnologically important yeasts, including 16 newly sequenced. We identify a genetic code change, CUG-Ala, in Pachysolen tannophilus in the clade sister to the known CUG-Ser clade. Our well-resolved yeast phylogeny shows that some traits, such as methylotrophy, are restricted to single clades, whereas others, such as l-rhamnose utilization, have patchy phylogenetic distributions. Gene clusters, with variable organization and distribution, encode many pathways of interest. Genomics can predict some biochemical traits precisely, but the genomic basis of others, such as xylose utilization, remains unresolved. Our data also provide insight into early evolution of ascomycetes. We document the loss of H3K9me2/3 heterochromatin, the origin of ascomycete mating-type switching, and panascomycete synteny at the MAT locus. These data and analyses will facilitate the engineering of efficient biosynthetic and degradative pathways and gateways for genomic manipulation. PMID:27535936

    This paper analyzes the patterns of health biotechnology publications in six Latin American countries from 2001 to 2015. The countries studied were Argentina, Brazil, Chile, Colombia, Cuba and Mexico. Before our study, there were no data available on HBT development in half of the Latin-American countries we studied, i.e., Argentina, Colombia and Chile. To include these countries in a scientometric analysis of HBT provides fuller coverage of HBT development in Latin America. The scientometric study used the Web of Science database to identify health biotechnology publications. The total amount of health biotechnology production in the world during the period studied was about 400,000 papers. A total of 1.2% of these papers, were authored by the six Latin American countries in this study. The results show a significant growth in health biotechnology publications in Latin America despite some of the countries having social and political instability, fluctuations in their gross domestic expenditure in research and development or a trade embargo that limits opportunities for scientific development. The growth in the field of some of the Latin American countries studied was larger than the growth of most industrialized nations. Still, the visibility of the Latin American research (measured in the number of citations) did not reach the world average, with the exception of Colombia. The main producers of health biotechnology papers in Latin America were universities, except in Cuba were governmental institutions were the most frequent producers. The countries studied were active in international research collaboration with Colombia being the most active (64% of papers co-authored internationally), whereas Brazil was the least active (35% of papers). Still, the domestic collaboration was even more prevalent, with Chile being the most active in such collaboration (85% of papers co-authored domestically) and Argentina the least active (49% of papers).

    Biotechnology is a broad field encompassing diverse disciplines from agriculture to zoology. Advances in research are occurring at a rapid pace, and applications that have broad implications socially, economically, ecologically and politically are emerging. Along with notable benefits, environmental consequences that affect core quality-of-life issues for present and future generations are materializing. The precautionary principle should be applied to biotechnology research, activities and products, and a strengthened, enforceable and proactive regulatory framework is needed. The environmental impacts of agriculture, aquaculture, genetically modified organisms (GMOs) and even pharmaceuticals are raising public concerns and demonstrate the need for guidance from a variety of social, economic and scientific disciplines to insure the benefits of biotechnology are enjoyed without unacceptable and irreversible environmental costs.

    To transform developing and least developing countries into industrialised ones, biotechnology could be deployed along the value chain, to provide support to the development of the bio-based industries in such a way to ensure sustainability of the sector and to reduce negative environmental impacts that might otherwise occur. In agribusiness development, for instance, interventions could start from inputs and agricultural mechanization, modern processing technologies, packaging of perishable products, the promotion of food safety in the processing and regulatory environment; and interventions to improve competitiveness and productivity. Worth over USD 300 billion in revenue, the role of the biotechnology goes beyond industrial growth, since it provides opportunities for progress towards many of the UN sustainable development goals (SDGs). This paper reviews the status of industrial biotechnology as it relates to inclusive and sustainable industrial development. Copyright © 2017 Elsevier B.V. All rights reserved.

    As we transition from fossil fuel reliance to a new energy future, innovative microbial biotechnologies may offer new routes to maximize recovery from conventional and unconventional energy assets; as well as contributing to reduced emission pathways and new technologies for carbon capture and utilization. Here we discuss the role of microbiology in petroleum biotechnologies in relation to addressing UN Sustainable Development Goal 12 (ensure sustainable consumption and production patterns), with a focus on microbially-mediated energy recovery from unconventionals (heavy oil to methane), shale gas and fracking, bioelectrochemical systems for the production of electricity from fossil fuel resources, and innovations in synthetic biology. Furthermore, using wastes to support a more sustainable approach to fossil fuel extraction processes is considered as we undertake the move towards a more circular global economy. © 2017 The Authors.

    Marine microorganisms play key roles in every marine ecological process, hence the growing interest in studying their populations and functions. Microbial communities on algae remain underexplored, however, despite their huge biodiversity and the fact that they differ markedly from those living freely in seawater. The study of this microbiota and of its relationships with algal hosts should provide crucial information for ecological investigations on algae and aquatic ecosystems. Furthermore, because these microorganisms interact with algae in multiple, complex ways, they constitute an interesting source of novel bioactive compounds with biotechnological potential, such as dehalogenases, antimicrobials, and alga-specific polysaccharidases (e.g., agarases, carrageenases, and alginate lyases). Here, to demonstrate the huge potential of alga-associated organisms and their metabolites in developing future biotechnological applications, we first describe the immense diversity and density of these microbial biofilms. We further describe their complex interactions with algae, leading to the production of specific bioactive compounds and hydrolytic enzymes of biotechnological interest. We end with a glance at their potential use in medical and industrial applications.

    In their natural habitats microorganisms live in multi-species communities, in which the community members exhibit complex metabolic interactions. In contrast, biotechnological production processes catalyzed by microorganisms are usually carried out with single strains in pure cultures. A number of production processes, however, may be more efficiently catalyzed by the concerted action of microbial communities. This review will give an overview of organismic interactions between microbial cells and of biotechnological applications of microbial communities. It focuses on synthetic microbial communities that consist of microorganisms that have been genetically engineered. Design principles for such synthetic communities will be exemplified based on plausible scenarios for biotechnological production processes. These design principles comprise interspecific metabolic interactions via cross-feeding, regulation by interspecific signaling processes via metabolites and autoinducing signal molecules, and spatial structuring of synthetic microbial communities. In particular, the implementation of metabolic interdependencies, of positive feedback regulation and of inducible cell aggregation and biofilm formation will be outlined. Synthetic microbial communities constitute a viable extension of the biotechnological application of metabolically engineered single strains and enlarge the scope of microbial production processes.

    With its diverse, living marine resources and rapidly growing educational and research infrastructure, the Sultanate of Oman is well-positioned to take advantage of the commercial opportunities presented by marine biotechnology. In recognition of potential development, an international symposium, Marine Biotechnology-Emerging Opportunities and Future Perspectives, was held in Muscat, November 12-13, 2013. Three keynote addresses were given, 23 oral presentations made, and a poster exhibition held. The final session reviewed national and regional issues, and the delegates agreed informally on a number of future actions. The potential for future development of marine biotechnology was recognized by all delegates, and following the symposium, they were surveyed for their views on how best to sustain and develop new activities. One hundred percent of respondents found the meeting useful and would support future symposia in the region. Fifty-one percent of Omani respondents recognized major organizational challenges and obstacles to the development of marine biotechnology compared with 23 % of overseas respondents. The need for greater collaboration between research institutions within the GCC region was recognized by 98 % of all respondents. The presentations and survey outcomes are reviewed in this paper.

    Current automated approaches for compositional model checking in the assume-guarantee style are based on learning of assumptions as deterministic automata. We propose an alternative approach based on abstraction refinement. Our new method computes the assumptions for the assume-guarantee rules as conservative and not necessarily deterministic abstractions of some of the components, and refines those abstractions using counter-examples obtained from model checking them together with the other components. Our approach also exploits the alphabets of the interfaces between components and performs iterative refinement of those alphabets as well as of the abstractions. We show experimentally that our preliminary implementation of the proposed alternative achieves similar or better performance than a previous learning-based implementation.

    Withania somnifera is one of the most valued plants and is extensively used in Indian, Unani, and African systems of traditional medicine. It possess a wide array of therapeutic properties including anti-arthritic, anti-aging, anti-cancer, anti-inflammatory, immunoregulatory, chemoprotective, cardioprotective, and recovery from neurodegenerative disorders. With the growing realization of benefits and associated challenges in the improvement of W. somnifera, studies on exploration of genetic and chemotypic variations, identification and characterization of important genes, and understanding the secondary metabolites production and their modulation has gained significant momentum. In recent years, several in vitro and in vivo preclinical studies have facilitated the validation of therapeutic potential of the phytochemicals derived from W. somnifera and have provided necessary impetus for gaining deeper insight into the mechanistic aspects involved in the mode of action of these important pharmaceutically active constituents. The present review highlights some of the current developments and future prospects of biotechnological intervention in this important medicinal plant.

    Cytokinins represent an important group of plant growth regulators that can modulate several biotechnological processes owing to their ability to influence almost all stages of plant development and growth. In addition, the use of purine based cytokinins with aromatic substituent in C6 position of the purine moiety in tissue culture techniques is currently experiencing a surge in interest, made possible by the ongoing systematic synthesis and study of these compounds. This review article outlines progress in the synthesis of aromatic cytokinins, the in vitro and in vivo effects of these substances and insights gleaned from their synthesis. As the purine moiety in these compounds can be substituted at several positions, we examine each of the substitution possibilities in relation to the derivatives prepared so far. The discussion highlights the gradual simplification of their preparation in relation to their application in practice and summarizes the relevant organic chemistry literature and published patents.

    2011-09-02

    In our view, synthetic biology is an extension of the continuum of genetic science that has been used safely for more than 40 years by the biotechnology industry in the development of commercial products. Examples of synthetic biology use by biotechnology companies illustrate the potential to substantially reduce research and development time and to increase speed to market. Improvements in the speed and cost of DNA synthesis are enabling scientists to design modified bacterial chromosomes that can be used in the production of renewable chemicals, biofuels, bioproducts, renewable specialty chemicals, pharmaceutical intermediates, fine chemicals, food ingredients, and health care products. Regulatory options should support innovation and commercial development of new products while protecting the public from potential harms.

    The cellulosome is one of nature's most elegant and elaborate nanomachines and a key biological and biotechnological macromolecule that can be used as a multi-functional protein complex tool. Each protein module in the cellulosome system is potentially useful in an advanced biotechnology application. The high-affinity interactions between the cohesin and dockerin domains can be used in protein-based biosensors to improve both sensitivity and selectivity. The scaffolding protein includes a carbohydrate-binding module (CBM) that attaches strongly to cellulose substrates and facilitates the purification of proteins fused with the dockerin module through a one-step CBM purification method. Although the surface layer homology (SLH) domain of CbpA is not present in other strains, replacement of the cell surface anchoring domain allows a foreign protein to be displayed on the surface of other strains. The development of a hydrolysis enzyme complex is a useful strategy for consolidated bioprocessing (CBP), enabling microorganisms with biomass hydrolysis activity. Thus, the development of various configurations of multi-functional protein complexes for use as tools in whole-cell biocatalyst systems has drawn considerable attention as an attractive strategy for bioprocess applications. This review provides a detailed summary of the current achievements in Clostridium-derived multi-functional complex development and the impact of these complexes in various areas of biotechnology.

    A model study, funded by the National Library of Medicine (NLM) and conducted by the Southeastern/Atlantic Regional Medical Library (RML) and the University of Maryland Health Sciences Library, attempted to assess the information needs of researchers in the developing field of biotechnology and to determine the resources available to meet those needs in major academic health sciences centers. Nine medical schools in RML Region 2 were selected to participate in a biotechnology awareness study. A survey was conducted of the nine medical school libraries to assess their support of biotechnology research. To identify the information needs of scientists engaged in biotechnology-related research at the schools, a written survey was sent to the deans of the nine institutions and selected scientists they had identified. This was followed by individual, in-depth interviews with both the deans and scientists surveyed. In general, scientists obtained information from three major sources: their own experiments, personal communication with other scientists, and textual material (print or electronic). For textual information, most study participants relied on personal journal subscriptions. Tangential journals were scanned in the department's library. Only a few of these scientists came to the health sciences library on a regular basis. Further, the study found that personal computers have had a major impact on how biotechnologists get and use information. Implications of these findings for libraries and librarians are discussed.

    Metabolic flux analysis is a vital tool used to determine the ultimate output of cellular metabolism and thus detect biotechnologically relevant bottlenecks in productivity. ¹³C-based metabolic flux analysis (¹³C-MFA) and flux balance analysis (FBA) have many potential applications in biotechnology. However, noteworthy hurdles in fluxomics study are still present. First, several technical difficulties in both ¹³C-MFA and FBA severely limit the scope of fluxomics findings and the applicability of obtained metabolic information. Second, the complexity of metabolic regulation poses a great challenge for precise prediction and analysis of metabolic networks, as there are gaps between fluxomics results and other omics studies. Third, despite identified metabolic bottlenecks or sources of host stress from product synthesis, it remains difficult to overcome inherent metabolic robustness or to efficiently import and express nonnative pathways. Fourth, product yields often decrease as the number of enzymatic steps increases. Such decrease in yield may not be caused by rate-limiting enzymes, but rather is accumulated through each enzymatic reaction. Fifth, a high-throughput fluxomics tool hasnot been developed for characterizing nonmodel microorganisms and maximizing their application in industrial biotechnology. Refining fluxomics tools and understanding these obstacles will improve our ability to engineer highly efficient metabolic pathways in microbial hosts.

    Challenges concerning fruit trees and grapevines as long lived woody perennial crops require adapted biotechnological approaches, if solutions are to be found within a reasonable time frame. These challenges are represented by the need for correct identification of genetic resources, with the foreseen use either in conservation or in breeding programmes. Molecular markers provide most accurate information and will be the major solution for questions about plant breeders rights. Providing healthy planting material and rapid detection of newly introduced pathogens by reliable methods involving serological and molecular biological tools will be a future challenge of increases importance, given the fact that plant material travels freely in the entire European Union. But also new breeding goals and transgenic solutions are part of the biotechnological benefits, e.g. resistance against biotic and abiotic stress factors, modified growth habits, modified nutritional properties and altered processing and storage qualities. The successful characterization of transgenic grapevines and stone fruit trees carrying genes of viral origin in different vectors constructed under ecological consideration, will be presented. Beyond technical feasibility, efficiency of resistance, environmental safety and Intellectual Property Rights, also public acceptance needs consideration and has been addressed in a specific project. The molecular determination of internal quality parameters of food can also be addressed by the use of biotechnological tools. Patient independent detection tools for apple allergens have been developed and should allow to compare fruits from different production systems, sites, and genotypes for their content of health threatening compounds.

  15. Abstract Spatial Reasoning as an Autistic Strength

    2013-01-01

    Autistic individuals typically excel on spatial tests that measure abstract reasoning, such as the Block Design subtest on intelligence test batteries and the Raven’s Progressive Matrices nonverbal test of intelligence. Such well-replicated findings suggest that abstract spatial processing is a relative and perhaps absolute strength of autistic individuals. However, previous studies have not systematically varied reasoning level – concrete vs. abstract – and test domain – spatial vs. numerical vs. verbal, which the current study did. Autistic participants (N = 72) and non-autistic participants (N = 72) completed a battery of 12 tests that varied by reasoning level (concrete vs. abstract) and domain (spatial vs. numerical vs. verbal). Autistic participants outperformed non-autistic participants on abstract spatial tests. Non-autistic participants did not outperform autistic participants on any of the three domains (spatial, numerical, and verbal) or at either of the two reasoning levels (concrete and abstract), suggesting similarity in abilities between autistic and non-autistic individuals, with abstract spatial reasoning as an autistic strength.

    With ever-increasing molecular information about colorectal cancer (CRC), there is an expectation to detect more sensitive and specific molecular markers for new advanced diagnostic methods that can surpass the limitations of current screening tests. Moreover, enhanced molecular pathology knowledge about cancer has led to the development of targeted therapies, designed to interfere with specific aberrant biological pathways in cancer. Furthermore, biotechnology has opened a new window in CRC diagnosis and treatment by introducing different application of antibodies, antibody fragments, non-Ig scaffold proteins, and aptamers in targeted therapy and drug delivery. This review summarizes the molecular diagnostic and therapeutic approaches in CRC with a focus on genetic and epigenetic alterations, protein and metabolite markers as well as targeted therapy and drug delivery by Ig-scaffold proteins, non-Ig scaffold proteins, nanobodies, and aptamers.

    The European Commission has defined the Knowledge-Based Bio-Economy (KBBE) as the process of transforming life science knowledge into new, sustainable, eco-efficient and competitive products. The term "Bio-Economy" encompasses all industries and economic sectors that produce, manage and otherwise exploit biological resources and related services. Over the last decades biotechnologies have led to innovations in many agricultural, industrial, medical sectors and societal activities. Biotechnology will continue to be a major contributor to the Bio-Economy, playing an essential role in support of economic growth, employment, energy supply and a new generation of bio-products, and to maintain the standard of living. The paper reviews some of the main biotechnology-related research activities at European level. Beyond the 7th Framework Program for Research and Technological Development (FP7), several initiatives have been launched to better integrate FP7 with European national research activities, promote public-private partnerships and create better market and regulatory environments for stimulating innovation.

    The PHAR-IN (“Competences for industrial pharmacy practice in biotechnology”) looked at whether there is a difference in how industrial employees and academics rank competences for practice in the biotechnological industry. A small expert panel consisting of the authors of this paper produced a biotechnology competence framework by drawing up an initial list of competences then ranking them in importance using a three-stage Delphi process. The framework was next evaluated and validated by a large expert panel of academics (n = 37) and industrial employees (n = 154). Results show that priorities for industrial employees and academics were similar. The competences for biotechnology practice that received the highest scores were mainly in: “Research and Development”,‘“Upstream” and “Downstream” Processing’, “Product development and formulation”,“Aseptic processing”, “Analytical methodology”, “Product stability”, and “Regulation”. The main area of disagreement was in the category “Ethics and drug safety” where academics ranked competences higher than did industrial employees. PMID:28975907

    We conducted a survey of corporate preparedness for pandemic influenza among biotechnology and pharmaceutical companies in Montgomery County, Maryland, to determine the level of preparedness for this industry and geographic region. The survey, based on the HHS Business Pandemic Influenza Planning Checklist, established whether a company had a preparedness plan specific to pandemic influenza, the contents of its plan, or its reasons for a lack of a plan. A total of 50 companies participated in the survey. Of these, 40 did not have any type of preparedness plan, 3 were drafting plans, 6 had general preparedness plans that could be applied to an influenza pandemic, and only 1 company had a preparedness plan specifically designed to address pandemic influenza. Biotechnology and pharmaceutical companies in this geographic region are currently not well prepared for pandemic influenza. Public health officials should offer more help, possibly in the form of a model small business preparedness plan, and collaboration between companies should be encouraged to foster sharing of preparedness plans.

The Task Force was established in June 1990 by the European Commission and the White House Office of Science and Technology Policy. The Task Force has acted as an effective forum for discussion, coordination, and development of new ideas for the last 18 years. Task Force members are European Commission and US Government science and technology administrators who meet annually to enhance communication across the Atlantic, and to encourage collaborative research. Through sponsoringmore » workshops, and other activities, the Task Force also brings together scientific leaders and early career researchers from both sides of the Atlantic to forecast research challenges and opportunities and to promote better links between researchers. Over the years, by keeping a focus on the future of science, the Task Force has played a key role in establishing a diverse range of emerging scientific fields, including biodiversity research, neuroinformatics, genomics, nanobiotechnology, neonatal immunology, transkingdom molecular biology, biologically-based fuels, and environmental biotechnology. The EC-US Task Force has sponsored a number of Working Groups on topics of mutual transatlantic interest. The idea to create a Working Group on Environmental Biotechnology research was discussed in the Task Force meeting of October 1993. The EC-US Working Group on Environmental Biotechnology set as its mission 'To train the next generation of leaders in environmental biotechnology in the United States and the European Union to work collaboratively across the Atlantic.' Since 1995, the Working Group supported three kinds of activities, all of which focus one early career scientists: (1) Workshops on the use of molecular methods and genomics in environmental biotechnology; (2) Short courses with theoretical

    Data abstraction, a critical systematic review step, is time-consuming and prone to errors. Current standards for approaches to data abstraction rest on a weak evidence base. We developed the Data Abstraction Assistant (DAA), a novel software application designed to facilitate the abstraction process by allowing users to (1) view study article PDFs juxtaposed to electronic data abstraction forms linked to a data abstraction system, (2) highlight (or "pin") the location of the text in the PDF, and (3) copy relevant text from the PDF into the form. We describe the design of a randomized controlled trial (RCT) that compares the relative effectiveness of (A) DAA-facilitated single abstraction plus verification by a second person, (B) traditional (non-DAA-facilitated) single abstraction plus verification by a second person, and (C) traditional independent dual abstraction plus adjudication to ascertain the accuracy and efficiency of abstraction. This is an online, randomized, three-arm, crossover trial. We will enroll 24 pairs of abstractors (i.e., sample size is 48 participants), each pair comprising one less and one more experienced abstractor. Pairs will be randomized to abstract data from six articles, two under each of the three approaches. Abstractors will complete pre-tested data abstraction forms using the Systematic Review Data Repository (SRDR), an online data abstraction system. The primary outcomes are (1) proportion of data items abstracted that constitute an error (compared with an answer key) and (2) total time taken to complete abstraction (by two abstractors in the pair, including verification and/or adjudication). The DAA trial uses a practical design to test a novel software application as a tool to help improve the accuracy and efficiency of the data abstraction process during systematic reviews. Findings from the DAA trial will provide much-needed evidence to strengthen current recommendations for data abstraction approaches. The trial is registered

    We examine reverse mergers (RMs) in the biotechnology industry and find that, when compared to initial public offerings (IPOs), RMs are smaller, have significantly lower market valuations relative to size, and generally invest less. We also find that RMs exhibit positive abnormal returns on the announcement date and throughout the first year after the RM event. In looking at liquidity measures, we find that RMs tend to be less liquid than IPOs and that illiquidity is greater during the six-month lock-up period following the RM event. Thus, RMs may be an appropriate alternative financing vehicle in capital intensive, high-risk biotechnology companies which require accessing deeper and larger pools of investors in public capital markets across multiple milestone periods in a "pay for progress" environment.

    Phytochromes are photosensory phosphoproteins with crucial roles in plant developmental responses to light. Functional studies of individual phytochromes have revealed their distinct roles in the plant's life cycle. Given the importance of phytochromes in key plant developmental processes, genetically manipulating phytochrome expression offers a promising approach to crop improvement. Photo-biotechnology refers to the transgenic expression of phytochrome transgenes or variants of such transgenes. Several studies have indicated that crop cultivars can be improved by modulating the expression of phytochrome genes. The improved traits include enhanced yield, improved grass quality, shade-tolerance, and stress resistance. In this review, we discuss the transgenic expression of phytochrome A and its hyperactive mutant (Ser599Ala-PhyA) in selected crops, such as Zoysia japonica (Japanese lawn grass), Agrostis stolonifera (creeping bentgrass), Oryza sativa (rice), Solanum tuberosum (potato), and Ipomea batatas (sweet potato). The transgenic expression of PhyA and its mutant in various plant species imparts biotechnologically useful traits. Here, we highlight recent advances in the field of photo-biotechnology and review the results of studies in which phytochromes or variants of phytochromes were transgenically expressed in various plant species. We conclude that photo-biotechnology offers an excellent platform for developing crops with improved properties. Copyright © 2014 Elsevier Inc. All rights reserved.

    2015-11-15

    Industrial biotechnology aims to produce chemicals, materials and biofuels to ease the challenges of shortage on petroleum. However, due to the disadvantages of bioprocesses including energy consuming sterilization, high fresh water consumption, discontinuous fermentation to avoid microbial contamination, highly expensive stainless steel fermentation facilities and competing substrates for human consumption, industrial biotechnology is less competitive compared with chemical processes. Recently, halophiles have shown promises to overcome these shortcomings. Due to their unique halophilic properties, some halophiles are able to grow in high pH and high NaCl containing medium under higher temperature, allowing fermentation processes to run contamination free under unsterile conditions and continuous way. At the same time, genetic manipulation methods have been developed for halophiles. So far, halophiles have been used to produce bioplastics polyhydroxyalkanoates (PHA), ectoines, enzymes, and bio-surfactants. Increasing effects have been made to develop halophiles into a low cost platform for bioprocessing with advantages of low energy, less fresh water consumption, low fixed capital investment, and continuous production.

    Soil contamination caused by heavy metals and organic pollutants has drawn world-wide concern. Biotechnology has been applied for many years to the decontamination of soils polluted with organic and inorganic contaminants, and novel nanomaterials (NMs) has attracted much concern due to their high capacity for the removal/stabilization/degradation of pollutants. Recently, developing advanced biotechnology with NMs for the remediation of contaminated soils has become a hot research topic. Some researchers found that bioremediation efficiency of contaminated soils was enhanced by the addition of NMs, while others demonstrated that the toxicity of NMs to the organism negatively influenced the repair capacity of polluted soils. This paper reviews the application of biotechnology and NMs in soil remediation, and further provides a critical view of the effects of NMs on the phytoremediation and micro-remediation of contaminated soils. This review also discusses the future research needs for the combined application of biotechnology and NMs in soil remediation.

    Present work deals with the biotechnological production of fuel ethanol from different raw materials. The different technologies for producing fuel ethanol from sucrose-containing feedstocks (mainly sugar cane), starchy materials and lignocellulosic biomass are described along with the major research trends for improving them. The complexity of the biomass processing is recognized through the analysis of the different stages involved in the conversion of lignocellulosic complex into fermentable sugars. The features of fermentation processes for the three groups of studied feedstocks are discussed. Comparative indexes for the three major types of feedstocks for fuel ethanol production are presented. Finally, some concluding considerations on current research and future tendencies in the production of fuel ethanol regarding the pretreatment and biological conversion of the feedstocks are presented.

    Biotechnology has been used extensively in the development of vaccines for aquaculture. Modern molecular methods such as polymerase chain reaction (PCR), cloning and microarray analysis have facilitated antigen discovery, construction of novel candidate vaccines, and assessments of vaccine efficacy, mode of action, and host response. This review focuses on DNA vaccines for finfish to illustrate biotechnology applications in this field. Although DNA vaccines for fish rhabdoviruses continue to show the highest efficacy, DNA vaccines for several other viral and bacterial fish pathogens have now been proven to provide significant protection against pathogen challenge. Studies of the fish rhabdovirus DNA vaccines have elucidated factors that affect DNA vaccine efficacy as well as the nature of the fish innate and adaptive immune responses to DNA vaccines. As tools for managing aquatic animal disease emergencies, DNA vaccines have advantages in speed, flexibility, and safety, and one fish DNA vaccine has been licensed.

    New high-throughput culture-independent molecular tools are allowing the scientific community to characterize and understand the microbial communities underpinning environmental biotechnology processes in unprecedented ways. By creatively leveraging these new data sources, microbial ecology has the potential to transition from a purely descriptive to a predictive framework, in which ecological principles are integrated and exploited to engineer systems that are biologically optimized for the desired goal. But to achieve this goal, ecology, engineering and microbiology curricula need to be changed from the very root to better promote interdisciplinarity.

    The purpose of the work carried under this interchanges was to support the development of space flight biotechnology experiments in the areas of immunology and hematopoiesis to facilitate the commercial development of space. The studies involved the interaction and development of experiments with biotechnology companies for necessary ground-based studies to allow the development of flight studies. The thrust of the work was to develop experiments with the Chiron Corporation and Bioserve involving the use of interleukin-2 to modulate the effects of spaceflight on immune responses. Spaceflight has been shown to have multiple effects on immune responses (1). lnterleukin-2 is an immuno-regulator that could have potential to counter some of the alterations induced in immune responses by spaceflight (1). To test this possibility before flight, rats were suspended antiorthostatically (2) and treated with interleukin-2. Antiorthostatic suspension is a model for some of the effects of spaceflight on immune responses (2). The interleukin-2 was given to see if it could alter some of the effects of suspension. This was achieved. As a result of these studies, two flight experiments were developed and flown with the Chiron Corp. And Bioserve to determine if use of interleukin-2 could prevent or attenuate the effects of space flight on immune responses.

    Our ability to deal with abstract concepts is one of the most intriguing faculties of human cognition. Still, we know little about how such concepts are formed, processed, and represented in mind. For example, because abstract concepts do not designate referents that can be experienced through our body, the role of perceptual experiences in shaping their content remains controversial. Current theories suggest a variety of alternative explanations to the question of "how abstract concepts are represented in the human mind." These views pinpoint specific streams of semantic information that would play a prominent role in shaping the content of abstract concepts, such as situation-based information (e.g., Barsalou & Wiemer-Hastings, ), affective information (Kousta, Vigliocco, Vinson, Andrews, & Del Campo, ), and linguistic information (Louwerse, ). Rarely, these theoretical views are directly compared. In this special issue, current views are presented in their most recent and advanced form, and directly compared and discussed in a debate, which is reported at the end of each article. As a result, new exciting questions and challenges arise. These questions and challenges, reported in this introductory article, can arguably pave the way to new empirical studies and theoretical developments on the nature of abstract concepts. © 2018 Cognitive Science Society, Inc.

    Multitrophic level microbial loop interactions mediated by protist predators, bacteria, and viruses drive eco- and agro-biotechnological processes such as bioremediation, wastewater treatment, plant growth promotion, and ecosystem functioning. To what extent these microbial interactions are context-dependent in performing biotechnological and ecosystem processes remains largely unstudied. Theory-driven research may advance the understanding of eco-evolutionary processes underlying the patterns and functioning of microbial interactions for successful development of microbe-based biotechnologies for real world applications. This could also be a great avenue to test the validity or limitations of ecology theory for managing diverse microbial resources in an era of altering microbial niches, multitrophic interactions, and microbial diversity loss caused by climate and land use changes.

  4. Biotechnology in Switzerland: high on the public agenda, but only moderate support.

    PubMed

    Bonfadelli, Heinz; Dahinden, Urs; Leonarz, Martina

    2002-04-01

    In Switzerland, there have been intensive public debates about biotechnology because of the specific Swiss political system of direct democracy that led, in 1992 and 1998, to two national referenda on biotechnology regulation. As a result, the Swiss population is well informed but skeptical about this technology. These findings contrast with the deficit model of public understanding of science, which predicts a positive correlation between knowledge of, and support for, a specific technology. What role did the media play in the development of public opinion? This question is discussed because of a content analysis (time series) of national newspapers. In addition, representative surveys and focus groups yield insights into the public perception of biotechnology and the influence of mass communication for opinion formation.

    Clustered regularly interspaced short palindromic repeats (CRISPR) is poised to become one of the key scientific discoveries of the twenty-first century. Originating from prokaryotic and archaeal immune systems to counter phage invasions, CRISPR-based applications have been tailored for manipulating a broad range of living organisms. From the different elucidated types of CRISPR mechanisms, the type II system adapted from Streptococcus pyogenes has been the most exploited as a tool for genome engineering and gene regulation. In this review, we describe the different applications of CRISPR/Cas9 technology in the industrial biotechnology field. Next, we detail the current status of the patent landscape, highlighting its exploitation through different companies, and conclude with future perspectives of this technology.

    Different aspects of bacterial and fungal siderophore biotechnological applications will be discussed. Areas of application presented include, but are not limited to agriculture, medicine, pharmacology, bioremediation, biodegradation and food industry. In agriculture-related applications, siderophores could be employed to enhance plant growth due to their uptake by rhizobia. Siderophores hindered the presence of plant pathogens in biocontrol strategies. Bioremediation studies on siderophores discuss mostly the mobilization of heavy metals and radionuclides; the emulsifying effects of siderophore-producing microorganisms in oil-contaminated environments are also presented. The different applications found in literature based in medicine and pharmacological approaches range from iron overload to drug delivery systems and, more recently, vaccines. Additional research should be done in siderophore production and their metabolic relevance to have a deeper understanding for future biotechnological advances.

    Cholesterol is a steroid commonly found in nature with a great relevance in biology, medicine and chemistry, playing an essential role as a structural component of animal cell membranes. The ubiquity of cholesterol in the environment has made it a reference biomarker for environmental pollution analysis and a common carbon source for different microorganisms, some of them being important pathogens such as Mycobacterium tuberculosis. This work revises the accumulated biochemical and genetic knowledge on the bacterial pathways that degrade or transform this molecule, given that the characterization of cholesterol metabolism would contribute not only to understand its role in tuberculosis but also to develop new biotechnological processes that use this and other related molecules as starting or target materials. © 2012 The Authors; Microbial Biotechnology © 2012 Society for Applied Microbiology and Blackwell Publishing Ltd.

    Sub-Saharan Africa could have a shortfall of nearly 90Mt of cereals by the year 2025 if current agricultural practices are maintained. Biotechnology is one of the ways to improve agricultural production. Insect-resistant varieties of maize and cotton suitable for the subcontinent have been identified as already having a significant impact. Virus-resistant crops are under development. These include maize resistant to the African endemic maize streak virus and cassava resistant to African cassava mosaic virus. Parasitic weeds such as Striga attack the roots of crops such as maize, millet, sorghum and upland rice. Field trials in Kenya using a variety of maize resistant to a herbicide have proven very successful. Drought-tolerant crops are also under development as are improved varieties of local African crops such as bananas, cassava, sorghum and sweet potatoes.

    Taxol® (generic name paclitaxel) represents one of the most clinically valuable natural products known to mankind in the recent past. More than two decades have elapsed since the notable discovery of the first Taxol®-producing endophytic fungus, which was followed by a plethora of reports on other endophytes possessing similar biosynthetic potential. However, industrial-scale Taxol® production using fungal endophytes, although seemingly promising, has not seen the light of the day. In this opinion article, we embark on the current state of knowledge on Taxol® biosynthesis focusing on the chemical ecology of its producers, and ask whether it is actually possible to produce Taxol® using endophyte biotechnology. The key problems that have prevented the exploitation of potent endophytic fungi by industrial bioprocesses for sustained production of Taxol® are discussed. Copyright © 2014 Elsevier Ltd.

    Quantitative and qualitative studies of various aspects of the perception of biotechnology were conducted among 469 Slovenian high school students of average age 17 years. Our research aimed to explore relationships among students' pre-knowledge of molecular and human genetics, and their attitudes to four specific biotechnological applications. These applications-Bt corn, genetically modified (GM) salmon, somatic and germ line gene therapy (GT)-were investigated from the viewpoints of usefulness, moral acceptance and risk perception. In addition, patterns and quality of moral reasoning related to the biotechnological applications from the aspect of moral acceptability were examined. Clear gender differences were found regarding the relationship between our students' pre-knowledge of genetics and their attitudes to biotechnological applications. While females with a better genetics background expressed a higher risk perception in the case of GM salmon, their similarly well-educated male colleagues emphasized the risk associated with the use of germ line GT. With all four biotechnological applications, patterns of both rationalistic-deontological and teleological-and intuitive moral reasoning were identified. Students with poorer genetics pre-knowledge applied an intuitive pattern of moral reasoning more frequently than their peers with better pre-knowledge. A pattern of emotive reasoning was detected only in the case of GM salmon. A relatively low quality of students' moral reasoning, as demonstrated by their brief and small number of supporting justifications (explanations), show that there is a strong need for practising skills of argumentation about socio-scientific issues in Slovenian high schools on a much larger scale. The implications for future research and classroom applications are discussed.

    2014-01-01

    Yarrowia lipolytica is a nonpathogenic dimorphic aerobic yeast that stands out due to its ability to grow in hydrophobic environments. This property allowed this yeast to develop an ability to metabolize triglycerides and fatty acids as carbon sources. This feature enables using this species in the bioremediation of environments contaminated with oil spill. In addition, Y. lipolytica has been calling the interest of researchers due to its huge biotechnological potential, associated with the production of several types of metabolites, such as bio-surfactants, γ-decalactone, citric acid, and intracellular lipids and lipase. The production of a metabolite rather than another is influenced by the growing conditions to which Y. lipolytica is subjected. The choice of carbon and nitrogen sources to be used, as well as their concentrations in the growth medium, and the careful determination of fermentation parameters, pH, temperature, and agitation (oxygenation), are essential for efficient metabolites production. This review discusses the biotechnological potential of Y. lipolytica and the best growing conditions for production of some metabolites of biotechnological interest. PMID:24715814

    2007-03-01

    The products of modern biotechnology processes such as genetic engineering, DNA testing and cloning will increasingly impact on society. It is essential that young people have a well-developed scientific understanding of biotechnology and associated processes so that they are able to contribute to public debate and make informed personal decisions. The aim of this study was to examine the development of understandings and attitudes about biotechnology processes as students progress through high school. In a cross-sectional case study, data was obtained from student interviews and written surveys of students aged 12 to 17 years. The results indicate that students' ability to provide a generally accepted definition and examples of biotechnology, cloning and genetically modified foods was relatively poor amongst 12 13 year old students but improved in older students. Most students approved of the use of biotechnology processes involving micro-organisms, plants and humans and disapproved of the use of animals. Overall, 12 13 year old students' attitudes were less favourable than older students regardless of the context. An awareness of the development and range of students' understandings and attitudes may lead to a more appropriate use of biotechnology curriculum materials and thus improved biotechnology education in schools.

    Mineral-microbe interaction has been a key factor shaping the lithosphere of our planet since the Precambrian. Detailed investigation has been mainly focused on the role of bioweathering in biomining processes, leading to the selection of highly efficient microbial inoculants for the recovery of metals. Here we expand this scenario, presenting additional applications of bacteria and fungi in mineral dissolution, a process with novel biotechnological potential that has been poorly investigated. The ability of microorganisms to trigger soil formation and to sustain plant establishment and growth are suggested as invaluable tools to counteract the expansion of arid lands and to increase crop productivity. Furthermore, interesting exploitations of mineral weathering microbes are represented by biorestoration and bioremediation technologies, innovative and competitive solutions characterized by economical and environmental advantages. Overall, in the future the study and application of the metabolic properties of microbial communities capable of weathering can represent a driving force in the expanding sector of environmental biotechnology.

    Symbiotic interactions between insects and microorganisms are widespread in nature and are often the source of ecological innovations. In addition to supplementing their host with essential nutrients, microbial symbionts can produce enzymes that help degrade their food source as well as small molecules that defend against pathogens, parasites, and predators. As such, the study of insect ecology and symbiosis represents an important source of chemical compounds and enzymes with potential biotechnological value. In addition, the knowledge on insect symbiosis can provide novel avenues for the control of agricultural pest insects and vectors of human diseases, through targeted manipulation of the symbionts or the host-symbiont associations. Here, we discuss different insect-microbe interactions that can be exploited for insect pest and human disease control, as well as in human medicine and industrial processes. Our aim is to raise awareness that insect symbionts can be interesting sources of biotechnological applications and that knowledge on insect ecology can guide targeted efforts to discover microorganisms of applied value.

    Davison, Brian H.; Brandt, Craig C.; Guss, Adam M.

    Modern biotechnology has the potential to substantially advance the feasibility, structure, and efficiency of future biofuel supply chains. Advances might be direct or indirect. A direct advance would be improving the efficiency of biochemical conversion processes and feedstock production. Direct advances in processing may involve developing improved enzymes and bacteria to convert lignocellulosic feedstocks to ethanol. Progress in feedstock production could include enhancing crop yields via genetic modification or the selection of specific natural variants and breeds. Other direct results of biotechnology might increase the production of fungible biofuels and bioproducts, which would impact the supply chain. Indirect advances mightmore » include modifications to dedicated bioenergy crops that enable them to grow on marginal lands rather than land needed for food production. This study assesses the feasibility and advantages of near-future (10-year) biotechnological developments for a US biomass-based supply chain for bioenergy production. We assume a simplified supply chain of feedstock, logistics and land use, conversion, and products and utilization. The primary focus is how likely developments in feedstock production and conversion technologies will impact bioenergy and biofuels in the USA; a secondary focus is other innovative uses of biotechnologies in the energy arenas. The assessment addresses near-term biofuels based on starch, sugar, and cellulosic feedstocks and considers some longer-term options, such as oil-crop and algal technologies.« less
