摘　　要：[目的]筛选高效降解木质素的菌种。[方法]通过马铃薯琼脂平板培养、马铃薯液体摇瓶培养和变色反应,对采自吉文山枯木中的木质素降解菌进行了筛选,并对其降解构树的卡伯值和纤维素进行了测定。[结果]共筛选出3种对木质素降解能力较强的菌种,分别为JWS-1、JWS-2和向日葵菌核病菌。[结论]为进一步研究生物制浆奠定了基础。[Objective] The paper was to screen lignin-degrading strains with high efficacy.[Method] Through potato agar plate culture,potato liquid shake-flask culture and Bavendamm′s reaction,the lignin-degrading strains collected from the dead wood in Jiwen Mountain were screened,their Kappa values and cellulose for degrading papermulberry were also determined.[Result] A total of 3 species of strains with strong degradation ability on ligin were screened out,including JWS-1,JWS-2 and Sclerotinia sclerotiorum（Lib.）de Bary.[Conclusion] The study laid basis for further study on bio-pulping.
