Thin-layer chromatography (TLC) analysis of hydrolysis products released from (a and b) birchwood glucuronoxylan and (c and d) insoluble oat spelt arabinoxylan. Hydrolysis was conducted by Nf Xyn11A and Ta Xyn10A enzymes after different incubation times. Xylose to xylotetraose and arabinoxylobiose were used as standards. X, xylose; X2, xylobiose; X3, xylotriose; X4, xylotetraose; AX, arabinoxylobiose. The buffer salts retard the sample elution compared to the standards.
