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30min，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％。
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.
