White rot fungi produce lignin-degrading enzymes such as laccase, manganese peroxidase and lignin peroxidase. These extracellular oxidases efficiently degrade recalcitrant synthetic dyestuffs with diverse chemical structures. Here, we examined the activities of lignin-degrading enzymes in Trametes versicolor using triphenyl methane dyes, crystal violet (CV) and malachite green (MG). Both dyes were decolorized by T. versicolor in solid and liquid culture conditions. T. versicolor decolorized MG more quickly than CV in both conditions. Among three ligninolytic enzymes, laccase was most abundantly found in the decolorization processes of CV and MG. However, higher activity of laccase was needed to degrade CV than MG. The much less activity of MnP was also detected. But the increase of MnP activity was well corresponded to the decolorization efficiency of CV, suggesting the involvement of MnP in CV degrading process. However, its role in the degradation process of MG is supposed to be subsidiary to laccase.
