Abstract

The fungi were used for the decolourization of Azo dyes. Textile industry effluent such as Congo red, Rhodamine 6G and Malachite green accentuate environmental problems. Ganoderma applanatum mycelia has performed the highest percentage of azo-dye degradation after 6 days of its growth. It has exhibits 84 and 88 degradation percentage of 50 and 100ppm, respectively. PH value 6.0 was the best medium pH value for azo dye degradation, where it produced the highest percentage of dye degradation. Current results were interpreted that the color removal by the basidiomycetes fungi was mainly due to adsorption of the dyes to the mycelial surface, and also due to metabolic breakdown. These results suggest that G. applanatum vegetative mycelial form might be used for the treatment of azo dyes and textile dye industry effluent.
