Abstract
To obtain fundamental information on the production of fucose-containing xyloglucan oligosaccharides from peanut hulls by hydrolysis with industrial enzyme preparations, we have studied the structure of the oligosaccharide units of xyloglucan in peanut hulls. The oligosaccharide units of xyloglucan in peanut hulls were XXXG, XXLG, XLXG, XXFG, XLLG, and XLFG [where each (4)-β-linked D-glucosyl residue in the backbone is given a one-letter code according to its substituents: G=β-D-Glc; X=α-D-Xyl-(6β)-β-D-Glc; L=β-D-Gal-(2)-α-D-Xyl-(6β)-β-D-Glc; F=α-L-Fuc-(2)-β-D-Gal-(2)-α-D-Xyl-(6β)-β-D-Glc] in an approximate molar ratio of 33:4:5:25:6:27. An industrial hemicellulase preparation, Cellulosin T2, was found to be an appropriate enzyme source for producing xyloglucan oligosaccharides from peanut hull polysaccharides.
