Xylitol production from xylose by a self-isolated furfural and 5-hydroxymethyl furfural assimilating Pichia guilliermondii was studied under oxygen limitation. An extremely low initial volumetric oxygen transfer coefficient (0.075 h(-1)) was found most favorable to the xylitol production with yield of 0.61 g g(-1). Related enzymes activities were also investigated and discussed.
研究了在氧限制条件下，一株能够同化糠醛和 5-羟甲基糠醛的毕赤酵母（Pichia guilliermondii）从木糖生产木糖醇的情况。结果发现，极低的初始比体积氧传递系数（0.075 h(-1)) 最有利于木糖醇的生成，产率为 0.61 g g(-1)。还研究并讨论了相关酶的活性。
