| Abstract: | Six wild fungal strains, Trichoderma viride, T. harzianum, Gliocladium virens, Aspergillus terreus, A. niger and Tiarosporella phaseolina , isolated from decomposed jute stacks and diseased jute stem, were tested for their cellulolytic and hemicellulolytic activities and compared with T. reesei MCG 77. Filter paper cellulase production by all these wild strains were lower than those produced by T. reesei while some strains ( T. viride, T. harzianum and G. virens ) possessed carboxymethyl cellulase, β-glucosidase, xylanase and β-xylosidase activities comparable to T. reesei. A. terreus and A. niger produced 3·2 and 1·2 times respectively, greater β-glucosidase activity compared to T. reesei when grown on microcrystalline cellulose. |
