title: Treatment of rice straw with selected Cyathus stercoreus strains to improve enzymatic saccharification.
abstract: Seventeen Cyathus stercoreus isolates were tested for their ability to treat rice straw for improved enzymatic saccharification. These isolates showed a negative correlation between cellulase and xylanase activity and enzymatic saccharification yields. Incubation of rice straw pretreated at 60°C for 15 min with strain C. stercoreus TY-2 for 25 days resulted in an enzymatic saccharification yield of 57% as compared to a yield of 11% for the same straw in the absence of the fungus. These findings highlight the potential of this isolate for biological pretreatment of rice straw under conditions of low energy input.
