Enzymatic hydrolysis of cellulose and simultaneous fermentation to alcohol

OSTI ID:6307885
The simultaneous saccharification of cellulose and fermentation to ethanol, utilizing the cellulase enzymes of T. reesei and the yeast S. cerevisiae, has been shown to give increased rates of hydrolysis when compared to saccharification alone due to removal of competitive inhibition by glucose and cellubiose. The effect of increasing the concentrations of enzyme and substrate resulted in increased yields of ethanol while an increase in the size of the yeast inoculum had little effect on the yield. In addition, experiments indicate no inhibitory effect of the cellulase enzymes due to accumulation of ethanol in the reaction mixture.
