Examination of Physiological and Molecular Factors Involved in Enhanced Solvent Production by Clostridium beijerinckii BA101

Received 6 November 1998/Accepted 8 February 1999

The specific activities and the mRNA expression levels associated with coenzyme A transferase, acetoacetate decarboxylase, and butyraldehyde dehydrogenase were elevated in hyper-solvent-producing Clostridium beijerinckii BA101 during the exponential growth phase. The increase in expression of the sol operon and associated enzyme activities may be responsible for enhanced solvent production by C. beijerinckii BA101.
