Abstract(s)Commercial azo, triarylmethane, antraquinonic, and indigoid textile dyes are efficiently decolorized with enzyme preparations from Pleuratus ostreatus, Schizophyllum commune, Neurospora crassa, Polvporus sp., Sclerotium rolfsii, Trametes villosa, and Myceliophtora thermophila. The nature of substituents on the dyes' benzene rings influences enzyme activity, and hydroxyl and amino groups enhance decolorization. The presence of lignin peroxidase and/or manganese peroxidase in addition to Iaccase (P. Ostreatus, S. commune, S. rolfsii, N. crassa) increases decolorization by up to 25%, The effect of textile dyeing auxiliaries depends on the individual enzymes. 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.
