Abstract
Hydrolysis process of xylan by xylanase in membrane reactor was studied under conditions of xylan concentration 30.0 g/L,operating pressure 16 kPa,feed rate 400 mL/min,enzymatic hydrolysis time 12 h,pH value 5.0 and 48 ℃.Results showed that total sugars yield from enzymatic hydrolysis xylan was 60.10%;degree of polymerization(DP) of unhydrolyzed xylan was about 10,DP was not changed by use of alkaline;total sugars yield from enzymatic hydrolysis of unhydrolyzed xylan was 7.50%.
