Abstract: This study describes degradation ability of Aspergillus tamarii, mixed fungal culture (Trichoderma sp., and A. flavus) and Penicillium purpurogenum on various synthetic dyes. A. tamarii decolorized (> 90%) of coomassie brilliant blue (CBB), bromophenol blue (BPB), and malachite green (MG) dyes. Mixed fungal culture decolorized: CBB, 74; BPB, 78; and MG, 45%. P. purpurogenum decolorized: CBB, 91; BPB, 92; and MG, 52%. Dye decolorization was achieved by metabolism rather than by adsorption. Isolated fungal strains could effectively be used in development of alternative and eco-friendly method for removal and degradation of textile dyes.
