To use three kinds of screening plate,and to combine with quantitative degradation test of calcium lignosulphonate,three lignin-degradation strains,TP1,Tf1 and Ls21 were obtained.In order to confirm the degradation effect of the strains,the strain Tf1 (Pleurotus sajor-caju),was selected to do solid substrate fermentation test about the wheat straw and corn straw.And Phanerochaete chrysosporium (BKMF-1767) was made as a reference.The result showed that the degradation rate of Tf1 to the wheat straw and corn was 38.4% and 47.7% respectively,and it was higher than the reference strain (32.2% and 34.6%).This research improves the screening method system of lignin-degrading fungus.There is an important significance to expand the resource of lignin-degrading fungus and exploit the straw resource.
