摘　　要：通过调整培养基中氮源的含量,利用白腐菌Phanerochaete chryscoporium和Trametes versicolor对杨木木片处理28 d,分析了木片的质量得率及化学成分的变化.结果表明:当酵母浸出粉的用量为1 g.L-1时白腐菌对原料中的木素降解率最高,在氮源用量相同的情况下,白腐菌Phanerochaete chryscoporium比Tranetes versicolor降解木素的速率更快.The poplar chips were treated with white-rot fungi （Phanerochaete chryscoporium and Tranetes versicolor）for 28 d by changing nitrogen resource dosage in the culture medium. The yeild of the chips and the change of the chemical components have been analyzed. It showed that the decomposition efficiency of white-rot fungi to lignin in the raw material reached the maximum when the dosage of yeastextract is 1 g · L^-1 , and that white-rot fungus Ph. c decomposed lignin faster than white-rot fungi T. v under tha same dosage of nitrogen resource.
