The fungus 4 Isolates is Isolate B1, B6, C4 and F8 to test the ability of cellulase enzyme production using CMC broth. Incubated at 30 ºC for 4 days. Found that the fungi Isolate B1 The maximum enzyme activity as 0.053 ± 0.009 U/mL When tested, the ability to produce the enzyme cellulose model solid state fermentation. Found that fungal isolate C4 to the highest enzyme activity is 1.203 ± 0.045 U/g DW The fungus that produces the highest enzyme activity of Cellulase For production efficiency model solid state fermentation with rice straw as substrate. Sampling every second day for 14 days. Found that the fungus Isolate B1 and C4 Production of cellulase enzymes by up to 8 days equals 1.298 ± 0.067 and 1.162 ± 0.060 U/g DW respectively. And fungal isolates B6 production in 14 days. The enzyme activity was 1.621 ± 0.060 U / g DW. When the enzyme activity of all 3 isolate. To compare the efficiency of cellulase enzyme production, the results showed that the fungus isolate B6 give maximum activity on 14 was 1.621 ± 0.060 U/g DW which differ significantly at the P-Value < = 0.05.
