Abstract
d
-Xylulose, an intermediate of
d
-xylose catabolism, was observed to be fermentable to ethanol and carbon dioxide in a yield of greater than 80% by yeasts (including industrial bakers' yeast) under fermentative conditions. This conversion appears to be carried out by many yeasts known for
d
-glucose fermentation. In some yeasts, xylitol, in addition to ethanol, was produced from
d
-xylulose. Fermenting yeasts are also able to produce ethanol from
d
-xylose when
d
-xylose isomerizing enzyme is present. The results indicate that ethanol could be produced from
d
-xylose in a yield of greater than 80% by a two-step process. First,
d
-xylose is converted to
d
-xylulose by xylose isomerase.
d
-Xylulose is then fermented to ethanol by yeasts.
