| 摘 要： | 研究了白腐菌及其产生的木质素降解酶系对秸秆的木质素生物降解方法，探讨了黄孢原毛平革菌和杂色云芝单一菌株生物降解及双菌株联合降解木质纤维素的规律，白腐菌双菌联合固态培养可使木质素降解率达到47．64％，脱木素选择性为4．74．采用模拟大规模白腐菌堆积培养（厚度30cm）的方法降解秸秆木质素，培养30d，木素降解率为32．54％，表明此方法是一种可行的大规模生物顸处理方法．

| Abstract: | The biological degradation of lignin in corn straw with white rot fungi and lignin degradation enzyme secreted by white rot fungi was studied. The rule of lignocellulose degradation was discussed in single strain fermentation and two strains co-fermentation. The results showed that the rate of lignin degradation could reach 47.64% and the selection of lignin degradation was 4.74 in two-strains solid state co-fermentation. The degradation test was scaled up to 30cm height with white rot fungi. After 30 days, the rate of degradation could reach 32.54%. The results show that this method of large-scale biological pretreatment is feasible. |
