The invention discloses a method for promoting complex enzyme to catalyze degradation of straws by using active mediator combination, which includes the following steps: (1) preprocessing the straws: smashing the straws to obtain straw powder and sieving to be reserved; (2) preparing complex enzyme liquid: cultivating phanerochaete chrysosporium in liquid state to obtain the complex enzyme liquid; and (3) catalyzing degradation: adding the complex enzyme liquid into the straw powder, adding active mediator combination simultaneously, keeping warm, preserving moisture, and standing to finish degradation catalyzing. The method for degrading the straws improves enzymolysis rate of lignin in the straws, is favorable for decomposing and transforming and resource utilization of the straws, and is low in cost, simple in operation, low in operation cost, clean and free of pollution. |
