Microorganism compound microbial inoculums capable of efficiently degrading straw lignin

The invention provides microorganism compound microbial inoculums capable of efficiently degrading straw lignin. Floras achieve mutualistic symbiosis and synergistic interaction. In a straw fermentation process, three enzymes relating to the degradation of the lignin can be secreted at the same time; the activities of laccase, lignin peroxidase and manganese peroxidase are respectively 23.56 U/g,23.02 U/g and 21.74 U/g biomass; the lignin content of the fermented corn straws is reduced by 60.21 percent, and loss of sugar such as celluloses and hemicelluloses is avoided; the conversion rate ofthe celluloses in the pretreated corn straws is greater than that of non-treated corn straws by 142.14 percent; a screened compound bacterial strain is high in lignin degradation capacity, and the industrial utilization efficiency of the straws pretreated by the bacterial strain is obviously improved. The research provides a new pretreatment way for enzymolysis saccharification of lignocellulosesin the straws. 本发明提供了种高效降解
