摘要
对产朊假丝酵母As2.120,嗜鞣管囊酵母As2.1585和粗糙脉孢菌As3.1598等3种菌株在以木糖为惟一碳源的培养基上的生长和发酵情况进行研究.结果表明:嗜鞣管囊酵母As2.1585可以很好地发酵木糖生产酒精,在28℃,150r/min条件下,摇瓶发酵摩尔分数为3%的木糖72h,酒精体积分数达到最大值0.63%,木糖利用率为91.67%,每100g木糖产酒精22 9g,为理论酒精产率的48.7%.
Growth and fermentation of As 2.120,As 2.1585 and As 3.1598 are studied with xylose as the only carbon source.The results show that As 2.1585 can ferment xylose to alcohol.After 72 h bottle-rotating fermentation 3% xylose under 28 ℃ and 150 r/min,the maximum volume factor of alcohol and utilization rate of xylose are 0.63% and 91.67% respectively.Every 100 g xylose can yield 22.9 g alcohol and the production ratio is 48.7% of theoretical one.
