Analysis of xylooligosaccharides hydrolyzed by Tth xynB3 β-xylosidase. The products of the reaction were determined using thin layer chromatography. M, mixture of xylose, xylobiose, xylotriose and xylotetraose (2.5% each, wt/vol). a Lane 1, 2, 3, 4: samples of xylobiose, xylotriose and xylotetraose (5%, wt/vol) incubated with Tth xynB3 β-xylosidase (0.3 U) for 0.5h, 1 h, 2 h, 3h, respectively. b Lane 1: samples of XOs obtained from cornstalk without hydrolysis using Tth xynB3 β-xylosidase, lane 2, 3, 4: samples of XOs obtained from cornstalk incubated with Tth xynB3 β-xylosidase (0.3 U) for 1 h, 2 h, 3h, respectively.
