ABSTRACT

The aim of this work is to select filamentous fungal strains isolated from saw dust, soil, and decaying wood with the potential to produce xylanase and cellulase enzymes. A total of 110 fungi were isolated. Fifty-seven (57) of these fungi were isolated from soil samples, 32 from sawdust, and 19 from decaying wood. Trichoderma and Aspergillus had the highest relative occurrence of 42.6% and 40.8%, respectively. Trichoderma viride Fd18 showed the highest specific activity of 1.30 U mg−1 protein for xylanase, while the highest cellulase activity of 1.23 U mg−1 was shown by Trichoderma sp. F4. The isolated fungi demonstrated potential for synthesizing the hydrolytic enzymes.
