The hydrolysates from oat xylan using Xyn Ⅰ Xyn Ⅱ and their mixture for hydrolysis were analysed by HPLC. It was showed that Xyn Ⅰ hydrolyzed mainly the unsubstituted regions of oat xylan, and hydrolytes were high xylooligosaccharides; whereas Xyn Ⅱ exhibited greater catalytic versatility than Xyn Ⅰ and were able to attack substituted regions of the polysaccharide and showed greater activity to low xylooligosaccharides than Xyn Ⅰ to give xylobiose as the main hydrolysate. The purified xylanases were acidic enzymes.
