Butanol production ofClostridium acetobutylicumgrown on sugars found in hemicellulose hydrolysates

SummaryClostridium acetobutylicum was grown on a variety of different media and assayed for enhanced butanol production. Butanol values of about 90% of theoretical were obtained when glucose was used as the substrate. Five other sugars were assayed and the order of butanol production using these substrates was cellobiose>mannose>arabinose>xylose >galactose. The addition of calcium carbonate to the media to enhance xylose utilized was beneficial although lower butanol values were obtained.
