摘　　要：通过室内小麦秸秆固态发酵试验,研究了不同的碳、氮源对复合侧耳属白腐真菌Tf1(P.pulmonarius)和JG1(P.cornucopiae)降解麦秸中木质素能力的影响。结果表明,以葡萄糖为碳源,酒石酸铵为氮源能显著提高复合木质素降解菌对木质素的降解能力,发酵9d后小麦秸秆的失重率为14.87%,木质素含量为8.68%,木质素降解率为22.95%(p<0.05)。The present study was conducted to investigate the effect of selected carbon and nitrogen sources on lignin degradation ability by dual culture of two Pleurotus strains（P.pulmonarius Tf1 and P.cornucopiae JG1） on wheat straw substrates.Carbon source（glucose,Cane sugar,maizena,maltose and starch） and nitrogen source（ammonium tartrate,ammonium sulfate,peptone,wheat bran,soybean meal） were tested in these experiments.The greatest lignin degradation ability of Tf1＋JG1 was found using glucose as carbon source and ammonium tartrate as a nitrogen source.After fermentation for 9 days,weight loss for wheat straw was 14.87%,lignin content was 8.68% and lignin degradation was 22.95%（p〈0.05）.
