Ethanol was produced from wood chip hemicellulose hydrolyzate by a xylose-fermenting yeast mutant, Candida sp. XF 217. The rates of D-xylose consumption and ethanol production were greater under aerobic than fermentative conditions. The slow rate of fermentation under fermentative conditions could be overcome by supplementing the broth with D-xylose isomerase (glucose isomerase). The ethanol yield, as based on the sugar consumed, was approximately 90% of the theoretical value.
