Biological effects of an aqueous extract of Salix alba on the survival of Escherichia coli AB1157 cultures submitted to the action of stannous chloride.
2009-08-20

Stannous chloride (SnC12) is used in nuclear medicine as a reducing agent to obtain technetium-99m-radiopharmaceuticals. It have been reported that natural products might reduce the genotoxic and cytotoxic effects related to SnC12. This work evaluated the biological effects of an aqueous extract of Salix alba on the survival of Escherichia coli (E. coli) ...

Virus mediated transfer of genetic elements among bacteria in nature has become a major research topic in the last decade. Along with conjugation and transformation, transduction is a well-known mechanism resulting in horizontal gene transfer in procaryotic organisms. In the case of generalized transduction, all regions of the procaryotic chromosome or other genetic elements in the donor cell are ...

Bacterial glutathione: a sacrificial defense against chlorine compounds.
1996-04-01

Aerobic organisms possess a number of often overlapping and well-characterized defenses against common oxidants such as superoxide and hydrogen peroxide. However, much less is known of mechanisms of defense against halogens such as chlorine compounds. Although chlorine-based oxidants may oxidize a number of cellular components, sulfhydrl groups are particularly reactive. We have, therefore, ...

Raffinose Synthesis in Chlorella vulgaris Cultures after a Cold Shock 1
1989-02-01

Chlorella vulgaris cultures have been submitted to a chilling shock, bringing down the growing temperature from to 24�C to 4�C. Growth was stopped immediately, and concomitantly there was an accumulation of sucrose and a decrease in the starch content. The enzymes involved in sucrose metabolism were differentially affected by the chilling shock. ...
