Lignin degrading enzymes from Lentinula edodes have broad substrate specificities, and therefore can degrade a variety of recalcitrant compounds. In this study, the lignolytic biodegradation was investigated in five different L. edodes fungi (Chunbaegko, Sanjo 303ho, Poongnyunko, Baekhwahyang, and Soohyangko). The fungi were evaluated for their ability to decolorize Remazol Brilliant Blue R (RBBR) in malt extract broth medium. Sanjo 303ho, Poongnyunko, Baekhwahyang, and Soohyangko rapidly decolorized RBBR within 7 days. The activities of manganese peroxidase (MnP) and laccase were determined in the absence and presence of lignin. Poongnyunko displayed the highest ligninolytic activity on day 7 of incubation (2,809 U/ mg and 2,230 U/mg for MnP and laccase, respectively).
