Abstract

The rate of xylitol production from D-xylose increased with increasing yeast cell density. The optimal temperature for xylitol production is 36 degrees C, and the optimal pH range is from 4.0 to 6.0. At high initial yeast cell concentration of 26 mg/mL, 210 g/L of xylitol was produced from 260 g/L of D-xylose after 96 h of incubation with an indicated yield of 81% of the theoretical value.

从D-木糖生产木糖醇的速率随着酵母细胞密度的增加而提高。木糖醇生产的最佳温度为36摄氏度，最佳pH范围为4.0至6.0。在初始酵母细胞浓度为26 mg/mL的情况下，260 g/L的D-木糖在培养96小时后产生了210 g/L的木糖醇，所示产率为理论值的81%。
