Summary
Clostridium thermosaccharolyticum can produce up to 40 mM butanol. The formation of ethanol and butanol from starch and glucose by strain DSM 571 and by the new isolate 021 was compared. The ratios for ethanol/acetate and butanol/butyrate were higher during growth at neutral pH than at acidic pH. Butanol formation was greatly stimulated by the addition of butyrate.
