Filamentous fungus mutant strain capable of efficiently degrading lignocellulose and application thereof

The invention discloses a filamentous fungus mutant strain capable of efficiently degrading lignocellulose and application of the filamentous fungus mutant strain. The filamentous fungus mutant strain capable of efficiently degrading the lignocellulose, disclosed by the invention, is formed by a wild type filamentous fungus Podospora anserina through gene knockout of a photoperiod gene PaFrq. The application firstly finds that the filamentous fungus Podospora anserina of which the gene knockout photoperiod gene PaFrq is delayed in senescence, prolonged in life cycle and improved in growth speed, can more efficiently degrade lignocellulose, particularly improves the cellulase activity under a dark condition, has more efficient lignocellulose degradation capability, and can be used for degrading lignocellulose in a dark environment. And the method has important significance on the fungus fermentation industry, especially the more efficient conversion of fungus biomass. 本申请公开了一株高效降解木质纤维素的丝状真菌突变菌株及其应用。本申请高效降解木质纤维
