| Research Abstract |
Xylan facilitates degradation of cellulose by the basidiomycete Phanerochaete chrysosporium. Xylooligosaccharides, the degradation products of xylan, enhance expression of the genes encoding several cellulolytic enzymes, resulting in the above phenomenon. Moreover, cleavage of the ester linkages in acetyl residues of xylan and successive production of xylooligosaccharides seem to be a trigger of wood deterioration by this fungus.
