| Abstract
| - Trichoderma viride can utilize crude cell wall preparations from barley starchy endosperm as solesource of carbon and energy. In the process β-(1→3)(1→4)-glucan and arabinoxylan are released.The onset of release of the latter preceded that of glucan, consistent with arabinoxylan beingencountered and utilized first. The release of several enzymes was observed during growth ofTrichoderma on this substrate: endo-β-(1→3)(1→4)-glucanase, endo-β-(1→4)-glucanase, endo-xylanase, arabinofuranosidase, esterase, carboxypeptidase, and “β-glucan solubilase”. It is inferredthat each of these activities is necessary for the digestion of this substrate. Keywords: Barley; cell wall; endosperm; Trichoderma; enzymes
