The yeasts Pachysolen tannophilus and Pichia stipitis differed in their ability to utilize D-xylose in the presence of D-fructose. When P. tannophilus was grown aerobically in fructose-xylose mixture, the ketohexose was utilized preferentially over the pentose. However, in P. stipitis cultures, the converse was observed. The effect was associated with the ability of D-fructose to repress the induction of xylose reductase and xylitol dehydrogenase activities in P. tannophilus but not in P. stipitis. Both yeasts grew on D-fructose and fermented it to ethanol when it was supplied as the sole carbon source. The results suggest that there may exist some fundamental difference in the regulation of D-fructose metabolism between P. tannophilus and P. stipitis.
