以玉米芯为原料,采用假丝酵母发酵制备木糖醇。探讨了培养温度、pH值、接种量和装液量等4个相关因素对木糖醇得率的影响。采用响应面法建立二次回归模型,并对发酵工艺进行了优化。研究结果表明:当发酵温度为32.4℃、pH5.7、装液量为68.7%和接种量为8.7%（v/v）时,木糖醇的得率可达76.35%。

Xylitol was made from corncob with Candida tropicalis. The effects of the time of culture temperature, pH value, inoculation size and the culture volume in flask on xylitol yield were discussed. The process was optimized and analyzed with response surface methodology, and quadratic regression model was founded. The result showed that the xylitol yield was 76.35% as culture temperature was 32.4 ℃, pH value was 5.7, the culture volume in flask ...
