NADH-linked aldose reductase: The key to anaerobic alcoholic fermentation of xylose by yeasts

The kinetics and enzymology of o-xylose utilization were studied in aerobic and anaerobic batch cultures of the facultatively fermentative yeasts Candida utilis, Pachysolen tannophilus, and Pichia stipitis. These yeasts did not produce ethanol under aerobic conditions. When shifted to anaerobiosis cultures of C. utilis did not show fermentation...
