Decolorization rate of dyes using lignin peroxidases of Phanerochaete chrysosporium

The basidiomycetous fungus Phanerochaete chrysosporium excretes extracellular lignin peroxidases (LiP) which were used in decolorization experiments with different commercial dyes. Very similar patterns in the kinetic curves of decolorization for dyes of different chemical classes and structures were observed. Decolorization is nonspecific, i.e., not dependent on the chromophoric system, slightly dependent on the auxochromic group, and not dependent on the sign and distribution of the charge. It is useful for decolorizing a large number of dyes of diverse structural classes.
