摘　　要：通过对木质素具有降解能力的黄孢原毛平革菌进行紫外辐射诱变处理，选育出一株具有较强褐煤降解能力的突变体，对义马原褐煤的降解率从31．84％提高到37．6％，硝酸处理义马褐煤的降解率从32．55％提高到51．62％。试验研究还应用了FTIR对煤微生物转化产物进行了测试分析，结果表明其芳香聚合度和分子量有很大程度的降低，官能团含量也发生了变化。A mutant of Phanerochaete chrysosporium, which is capable of degrading lignin, was bred by ultraviolet ray irradiation and this mutant strain shows high capability of degrading of lignite. The degradation ratio of original Yima lignite and nitric acid treated Yima lignite by this mutant are 37.6% and 51.62% respectively, whereas those by the original strain are 31.84% and 32.55% respectively. FTIR analyses of the lignite converted product show that its polymerization degree and average molecular weight are both greatly reduced. The content of the functional groups also been altered.
