The Production of Xylito and D-Xylonic Acid by Yeast

Abstract

Pichia quercibus Phaff et Knapp produced xylitol and D-xylonic acid by aerobic dissimilation of D-xylose at good yield of 40% of sugar consumed. The products were isolated from the fermented broth and identified. It would be interesting that both of xylitol, a reduction product of D-xylose, and D-xylonic acid, an oxidation product, are accumulated in the fermented broth.
