Abstract
Several tones of agricultural wastes are burnt and dumped annually worldwide. However, certainly there is more than one way to reuse them in productive manner, such as production of biogas and organic fertilizer. In the production of biogas fungal cellulolytic enzymes can be used as pretreatment agent for the fermentation process. Here 21 different fungi were cultured and among those higher cellulose degrading varieties were screened, extracted enzymes were examined for their activity by filter paper assay and DNS reagent method. In addition, further cultures are made on rice straw which is a common agro-waste in Asia. In straw substrate highest activity of 42.61 FPU/ml was denoted by Helminthosporium sp. where the saccharification was 3.8%, it is seconded by Cladosporium sp. where the activity was 40.36 FPU/ml. Enzymes of Trichoderma sp. and Aspergillus sp. also showed considerable activity.
