【摘要】 采用160~180℃的高温对木聚糖酶解残渣中残余木聚糖进行预处理,并将预处理液酶水解。最优反应条件为180℃预处理30 m in,残余木聚糖的42.54%被有效降解,上清液中低聚木糖(XOS)的含量占上清液总糖的32.13%。上清液经木聚糖酶酶解后,低聚木糖的含量可达到上清液总糖的84.93%。更多还原

【Abstract】 The enzymatic hydrolysis residues of xylan was pretreated under high temperature from 160℃ to 180℃,then the filtrate of the pretreated suspension was enzymatically hydrolysed.Under the optimal condition of pretreatment for 30 min at 180℃,(42.54 %) of xylan residues could be decomposed efficiently and the yield of xylooligosaccharides(XOS)was 32.13 % of the total carbohydrates of the supernatant.After enzymatic hydrolysis,the yield of XOS could be up to 84.93 % of total carbohydrates of the supernatant.更多还原
