Abstract To clarify the effects of several carbohydrates on the biodegradation of lignin by Pleurotus ostreatus. The strain was cultured on the media formulated with lignin and carbohydrates such as cellulose, xylan, collobiose, glucose and xylose, which was added individually. The culture mixtures grown 36 days were filtered and then estimated the degree of lignin biodegradation. It was found that the growth of P. ostreatus was stimulated and the depoly-merization was also increased by the addition of carbohydrates. When the carbohydrates were not added, polymerization was apparent in stead of depolymerization. In the case of glucose as an added carbohydrate, the content of lignin by the nitrosolignin method was greatly (about 7.4 times) decreased than control which contains lignin as a carbon source. The peak of lignin at 280nm in UV spectra was decreased about 27% after 27 days of culture. As results, it was assumed that lignin biodegradation was correlated to the carbohydrates and especially glucose was very significant role in lignin degradation.
