The fungi were used for the decolourization of azo dyes such as congored, methylorange, erichrome black-T and also for decolourization of the dye industry effluents. Removal of azo dyes from aqueous solution by Schizophyllum commune (50 μm) concentration showed 96.86% of colour removal in congored, 97.57% in methylorange and 97.40% in erichrome black-T on fourth day respectively. Lenzites eximia decolourised congo red by 95.50%, methylorange by 94.79% and erichrome black-T by 95.36% at (50 μm) concentration respectively on fourth day. Removal of textile dye effluent in batch mode showed 76.15% decolourisation and in continuous mode 55.92% on 5th day by Schizophyllum commune. In Lenzites eximia 75.23% and 54.60% of decolourization was observed in batch and continuous mode respectively on 5th 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. The results suggested that Schizophyllum commune is more efficient than Lenzites eximia for the treatment of azo dyes and textile dye industry effluent in both batch mode and continuous mode.Read More
