Structures of the oligosaccharides from the enzymic hydrolysis of hemicellulose by a hemicellulase of Ceratocystis paradoxa.
And endo-hemicellulase (HC-II) of Ceratocystis paradoxa degraded spear-grass hemicellulose B to a series of mixed oligosaccharides. Four neutral oligosaccharides (AraXyl2, AraXyl3, Xyl2, and Xyl3), isolated by preparative paper chromatography, were shown by enzymic and methylation techniques to constitute a series of beta-(1 leats to 4)-D-xylose and O-alpha-L-arabinofuranosyl-(1 leads to 3)-O-beta-D-xylopyranosyl-(1 leads to 4)-O-beta-D-xylopyranosyl-(1 leads to 4)-D-xylose, respectively, the latter being a new compound.
