Studies on Phanerochaete Chrysosporium by Ultraviolet Ray and Biodegradation of Lignite
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.XRD and 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 is also been altered.
