Reaction Steps

When evaluated for growth on glucose, xylose, and cellobiose in 250-mL flasks, mutagenized strains 22-1-12 and 14-2-6 achieved the highest ethanol levels, productivities, and fermentation efficiencies on glucose, strains WT-2-1 and 22-1-1 performed slightly better than the other strains on cellobiose, and strains 14-2-6 and 22-1-12 performed best on xylose. However, compared to the results with glucose at 48 h (about 18 g/L ethanol), these strains produced only about 3 g/L with xylose at 96 h. Less than half the consumed xylose was converted to ethanol.
