Abstract

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 MUCL were investigated. pH = 4.5 and the media III were found to be the most suitable ones among the others tested. Compared to the other carbon and nitrogen sources tested, glucose and urea resulted in better decolorization performances. High TOC/N ratio (TOC/N > 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%). Published by Elsevier Science Inc.
