Role of Laccase and Low Molecular Weight Metabolites from Trametes versicolor in Dye Decolorization

Role of Laccase and Low Molecular Weight Metabolites from Trametes versicolor in Dye Decolorization

The studies regarding decolorization of dyes by laccase may not only inform about the possible application of this enzyme for environmental purposes, but also may provide important information about its reaction mechanism and the influence of several factors that could be involved. In this paper, de...
