IMPACT OF VITAMINS ON CELLULOLYTIC, PECTOLYTIC AND PROTEOLYTIC ACTIVITY OF MYCORRHIZAL FUNGI

The objective of the present work was to study the effect of vitamins on enzyme production in some ectomycorrhizal fungi. It was found that Hebeloma crustuliniforme was more cellulolytic and pectolytic than Lac caria laccata and Pisolithus tinctorius. H, crustuliniforme and P. tin ctorius but not L, laccata produced proteolytic enzymes. The vitamins did not influence the proteolytic and pectolytic activity of the fungi . The vitamins used (especially biotin) also did not affect or repress the cellulolytic activity of the fungi studied.
