<P>For the conversion of cellulose into biofuel by microorganisms is being studied intensively. This research isolate and screen efficient cellulolytic microorganism from bamboo forest soil based on growth rate on CMC plate, the size of transparent circle, disintegration effect of filter paper, and CMC enzyme activity assay. As a result, efficient cellulose-decomposing fungus J6-1 was obtained. The strains possessed higher filter paper degrading ability and CMC enzyme activity, disintegrating the filter paper into 42.3% at the 5th days and reaching the highest CMC enzyme activity 6.87IU/mL after 120 hours of shake flask fermentation. Strains J6-1 is preliminarily identified as<I>Penicillium</I>by morphological observation and a great potential cellulolytic strains.</P>
