【摘要】 木糖醇在食品、医药及化工行业中有着广泛的用途而深受关注。但是 ,传统的化学法生产木糖醇需要一系列复杂的分离纯化步骤 ,过高的生产成本限制了木糖醇的使用范围。发酵工艺生产木糖醇无需木糖的纯化步骤 ,是取代化学合成法的一条可行工艺路线。本文着重介绍产木糖醇的微生物 ,酵母对木糖的同化途径 ,半纤维素水解物的脱毒方法 ,影响木糖醇发酵的工艺条件等更多还原

【Abstract】 Xylitol has attracted much attention because of its many applications in the food,medicine and chemical industries.However the use has been limited by its high price.This coast is a result of the extensive purification steps needed for the preparation of a pure xylose solution,which is essential for the chemical process.The fermentative process of xylitol is an interesting alternative to conventional chemical process,since it does not require initial xylose purification.The present review describes the advantage of xylitol production by fermentation,xylitol producting microorganisms,metabolic pathway of xylose in yeasts,detoxification of hemicellulose hydrolysates and fermentative conditions affecting xylitol production.更多还原
