✦ Synopsis

Ethanol was produced from wood chip hemicellulose hydrolyzate by a xylose-fermenting yeast mutant, Candida sp. XF 217.

The rates of Dxylose 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.

A mutant strain of Candida sp. XF 217, was found to produce ethanol from D-xylose aerobically as weil as anaerobically. The rate of ethanol production under aerobic conditions was greater, indicating an oxygen requirement for the uptake of D-xylose in XF 217. Ethanol was also produced by XF 217 when
