Abstract
Kinetics of anaerobic ethanol fermentation by Clostridium thermohydrosulfuricum were investigated for the one-step production of ethanol from starch. A mutant strain with a high ethanol yield was induced from C. thermohydrosulfuricum. The mutant, designated as ME4, produced anaerobically 6.1 g/l of ethanol, 3.1 g/l of lactate and 0.1 g/l of acetate from 20 g/l of starch at
