ABSTRACT
The cellulase production and extraction from Trichoderma Longibrachiatum ANU_3-958 were reported. The results indicated that maximum enzyme activity can be obtained when the fungus was grown on a solid medium for 144 hours, the proportion between the solid culture and the extracting agent was about 1:7(W/V) and extract was precipitated twice by adding solid (NH_4)_2SO_4. Cellulase powder obtained by freeze drying was analysed for its related enzyme activities. The highest CMC and FPA enzyme activity are about 2788.89IU/g enzyme powder and 79.44IU/g enzyme powder respectively. The yield for the solid culture is about 13.28% averagely.
