Abstract A newly isolated, anaerobic, mesophillic bacterium, Clostridium sp. strain YK-3, ferments pentoses, hexoses, oligosaccharides and polysaccharides, such as soluble starch and glycogen, to ethanol and acetate. The potential of this strain for ethanol and amylase production has been examined. Ethanol was the major product and acetate a minor one. The organism could grow with soluble starch in the presence of 40 g ethanol/l. Extracellular α-amylase activity was detected when the strain was cultivated with soluble starch, glycogen or dextrin. The optimum pH of this amylase was 5.5 to 7.5 with an optimum temperature of 50°C.
