The fungi were used for the decolourization of Azo dyes such as Congo red, Rhodamine 6G, Malachite green, and also for Textile industry effluent. Removal of azo dyes from aqueous solution by Poria sp (50 μM) concentration showed 93% of colour removal in Congo red, 64.4% in Rhodamine 6G and 94.8% in Malachite green on the fifth day. Ganoderma sp decolourized Congo red by 77%, Rhodamine 6G by 65.3% and Malachite green by 75.2% at (50 μM) concentration on fifth day, respectively. Trametes sp decolourized Congo red by 89%, Rhodamine 6G by 54.5% and Malachite green by 76.1% at (50 μM) concentration on fifth day. Textile industry effluent was treated by the fungi in batch and continuous modes. Removal of textile dye effluent in batch mode showed 92.08% decolourization, and in continuous mode 70.74% on 7 th day by Poria sp. In Ganoderma sp, 90.36% and 65.40% of decolourization was observed in batch and continuous mode, respectively on 7 th day. In Trametes sp, 87.09% and 65.40% of decolourization was observed in batch and continuous mode, respectively on 7th day. From the results, it was interpreted that the colour removal by the basidiomycetes fungi were mainly due to adsorption of the dyes to the mycelial surface, and also due to metabolic breakdown. These results suggested that Poria sp is more efficient than Ganoderma sp and Trametes sp for the treatment of azo dyes and textile dye industry effluent, in both batch and continuous mode.Read More
