This research seeks to illucidate the molecular mechanisms used by the obligate anaerobe, Clostridium acetobutylicum to regulate the synthesis and activity of the key enzymes catalyzing reactions in this organism's fermentation pathway. Report is hereby made on the isolation and characterization of regulatory mutants, development of DNA transformation of protoplasts, ...

The overall objective of this project is to elucidate the detailed mechanism by which solvent-forming bacteria such as Clostridium acetobutylicum regulate the well-known shift in fermentation pathway between alcohol-acetone and organic acid production. It...

The overall objective of the project is to develop an integrated two-stage fermentation process for conversion of coal-derived synthesis gas to a mixture of alcohols. This is achieved in two steps. In the first steps, Butyribacterium methylotrophicum converts carbon monoxide (CO) to butyric and acetic acids. Subsequent fermentation of the acids by Clostridium acetobutylicum ...

The overall objective of this project is to elucidate the detailed mechanism by which solvent-forming bacteria such as Clostridium acetobutylicum regulate the well-known shift in fermentation pathway between alcohol-acetone and organic acid production. It is desired to eventually isolate and describe: (1) the regulatory genes and protein elements that determine induction of ...

The overall objective of the project is to develop two stage fermentation process for conversion of coal-derived synthesis gas to a mixture of alcohols. This is achieved in two steps. In the first step, B .methylotrophicum converts carbon monoxide (CO) to butyric and acetic acids. Subsequent fermentation of the acids by Clostridium acetobutylicum leads to the production of ...

The goals of this project are to determine the growth kinetics and the relationships that exist between microbial growth, microbial product formation and oil recovery, and to develop mathematical models that predict microbial activity in porous materials. The studies on the influence of microbial growth and product formation on the recovery of residual oil from Berea sandstone cores were continued ...
