Effects of environmental conditions such as pH, media composition, carbon and nitrogen sources, TOC/N ratio, and dyestuff concentrations on decolorization of reactive phytalocyanin type textile dyestuff Everzol Turquoise Blue G by white rot fungi, Coriolus versicolor 20) or low nitrogen concentration was essential for effective decolorization of the dyestuff. Dyestuff concentration should be lower than 500 mg/l for complete decolorization. Only partial decolorization was observed for dyestuff concentrations above 500 mg/l. Adsorption of the dyestuff on surfaces of the fungi was insignificant (<20%).
