Abstract

Lignocellulolytic fungi were tested for growth and enzyme production on solid substrates such as extracted sweet sorghum pulp and wheat straw. A Gliocladium sp. was best adapted to sweet sorghum pulp with about 6.0 Filter Paper Unit (FPU)/Dry Weight (DW) cellulase activity, 14.0 IU/g DW beta glucosidase activity, 1900 IU/g DW xylanase activity and 1500 Endoglucanase Unit (EGU)/g DW endoglucanase activity. On wheat straw a Trichoderma hamatum strain produced about 7000 IU/g DW xylanase activity and a Penicillium strain 34 IU/g DW beta glucosidase activity, surpassing Trichoderma reesei Rut C30 in these categories (10.0 IU/g DW beta glucosidase and 3600 IU/g DW xylanase). All selected wild strains surpassed Trichoderma reesei QM 6a, the parent of Rut C30 in enzyme production. The Gliocladium and Trichoderma hamatum strains grew considerably faster on both substrates than other tested fungi.
