Effect of Yeast Extract and Vitamin B(12) on Ethanol Production from Cellulose by Clostridium thermocellum I-1-B.
Addition to media of yeast extract, a vitamin mixture containing vitamin B(12), biotin, pyridoxamine, and p-aminobenzoic acid, or vitamin B(12) alone enhanced formation of ethanol but decreased lactate production in the fermentation of cellulose by Clostridium thermocellum I-1-B. A similar effect was not observed with C. thermocellum ATCC 27405 and JW20.
