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 synthesis of the solvent-pathway enzymes; and (2) how this regulation system interacts with the sporulatin induction and development program and with related pathways such as granulse and exopolysaccharide formation in clostridia. A working model forhow clostridial control systems work can be derived from recent research on stress systems in E. coli and sporulation in Bacillus subtilis.
