The white rot fungus Coriolus hiysutus decolorized several recalcitrant dyes. Four different types of dyes, including azo, triphenyl methane, heterocyclic, and polymeric dye, were treated by the mycelial preparation. Triphenyl methane dye, bromophenol blue lost over 95% of its color. Congo red and Poly R-478 were decolorized less than bromophenol blue, 57 and 55%, respectively. However, heterocyclic dye, methylene blue was not decolorized significantly and only red shift was observed. Extracellular laccase and peroxidase activities were appeared maximally in high level of dye decolorization media. In electrophoretic experiments, common active bands of laccase and peroxidase were found in all dye decolorized medium. These results indicated that the culture conditions which yield high levels of laccase and peroxidase activity lead to high levels of dye decolorization, and these two enzymes might be play an important roles in dye decolorization.
