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.
对 17 株 Cyathus stercoreus 分离株进行了测试，以评估它们将稻草进行改良酶解糖化的能力。这些分离株的纤维素酶和木聚糖酶活性与酶解糖化产率呈负相关。与不添加真菌的情况下 11%的产率相比，将稻草在 60°C 下预处理 15 分钟，然后用 C. stercoreus TY-2 菌株培养 25 天，可将酶解糖化产率提高到 57%。这些发现强调了该分离株在低能耗条件下对稻草进行生物预处理的潜力。
