摘要
高温(121℃)酸解水洗和未水洗甜高粱秸秆,测其酸解液主要成分;并利用诱变体N6和酿酒酵母TO5对其酸解液进行发酵,结果表明:水洗秸秆酸解液中木糖为主要成分,未水洗秸秆中木糖含量相对较少;发酵实验结果表明,诱变体N6能很好发酵木糖,而酿酒酵母TO5不能发酵木糖。
The main components of the hydrolysate from sweet sorghum stalk （washed or unwashed by sulphuric acid at 121 ℃ ） were determined. Then mutant N6 and Saccharomyces cerevisiae TO5 were used for the fermentation of hemicellulose acid hydrolysis solution. The results showed that the main component of the hydrolysate from sweet sorghum stalk （washed） was xylose （xylose content was lower in the stalk （unwashed））. And the fermentation experimental results indicated that mutant N6 could ferment xylose, however, Saccharomyces cerevisiae T05 could not ferment xylose.
