The ability to assimilate D-glucose and D-xylose was studied in 21 yeast species of the following genera: Candida, Kluyveromyces, Pachysolen, Pichia, and Torulopsis. All the cultures fermented D-glucose with the formation of ethanol. During the assimilation of D-xylose, ethanol was produced by P. stipitis and C. shehatae, whereas xylitol was produced by C. didensiae, C. intermediae, C. parapsilosis, C. silvanorum, C. tropicalis, K. fragilis, K. marxianus, P. guillermondii, and T. molishiama. The yeast P. tannophilus produced comparable amounts of both alcohols. The possible use of xylose-assimilating yeasts for the production of xylitol and ethanol is discussed.
对以下属的21种酵母进行了同化D-葡萄糖和D-木糖能力的研究：假丝酵母属、克鲁维酵母属、厚壁酵母属、毕赤酵母属和球拟酵母属。所有培养物都能发酵D-葡萄糖并生成乙醇。在同化D-木糖过程中，树干毕赤酵母和嗜鞣管囊酵母产生乙醇，而迪登斯假丝酵母、中间假丝酵母、近平滑假丝酵母、森林假丝酵母、热带假丝酵母、脆壁克鲁维酵母、马克斯克鲁维酵母、季也蒙毕赤酵母和莫氏球拟酵母产生木糖醇。嗜鞣管囊酵母产生的两种醇类数量相当。讨论了利用能同化木糖的酵母生产木糖醇和乙醇的可能性。
