Xylitol production is suppressed by D-glucose. We previously reported that the suppression was abrogated in the presence of NaCl. This was explained in part by high levels of xylose reductase (XR) activity. In this study, we investigated the effects of D-glucose on XR and xylitol dehydrogenase (XDH)
Xylitol was produced as a metabolic by-product by a number of yeasts when grown on medium containing D-xylose as carbon and energy sources. Among the yeast strains tested, a mutant strain of Oandida tropicalis (HXP2) was found to produce xylitol from D-xylose with a high yield (>90%). Ethanol was a
The production of extracellular xylitol from D-xylose by an efficient xylitol-producing yeast, Candida sp. L-102, was studied in shake flask cultures with different nitrogen sources in the basic salt medium. Maximum xylitol production was obtained with urea as the nitrogen source. A final concentrat
