Commercial azo, triarylmethane, antraquinonic, and indigoid textile dyes are efficiently decolorized with enzyme preparations from Pleurotus ostreatus, Schizophyllum commune, Neurospora crassa, Polyporus sp., Sclerotium rolfsii, Trametes villosa, and Myceliphtora thermophila. The nature of substituents on the dyes' benezene rings influence decolorization. The presence of lignin peroxidase and/or manganese peroxidase in addition to laccase(P. osteatus, S.commune, S.rolfsii, N.crassa) increases decolorization by up to 25%. The effect of textile dyeing auxiliaries depends on the individual enzyme. Polyporus sp. and T. villosa are inhibited up to 20% by copper and iron chelating agents and anionic detergents, while the S. commune enzymes lose up to 70% of their activity.
