Abstract: Lignin degrading white rot fungi, Phanerochaete chrysosporium, Schizophyllum commune and Lenzites eximia were isolated from the logs of Acacia nilotica, Tarmarindus indica, Eucalyptus grandis from the Western Ghats region of Karnataka, India. The fungi were used for the decolourization of azo dyes such as Acid orange 7, Methly red, and Evans blue. . P. chrysosporium 787 removed 94.8 per cent of acid orange 7 50 µM concentration. In S .commune removed 96.7 per cent of Acid orange 7 from aqueous solution. When the dye was treated with L. eximia maximum (95.5 %) dye removal was observed. For methyl red, P. chrysosporium 787 treatment maximum of 92.2 per cent dye was removed. In S. commune treatment, 98.5 per cent of methyl red was removed. The per cent of methyl red removal from aqueous solution by L. eximia was observed up to 96.0 per cent. In Evans blue, P. chrysosporium 787 treatment, resulted in 90.2 per cent dye was removed. When the dye was treated with S. commune, 97.4 per cent dye was removed. In L. eximia treatment, the per cent of dye removal was observed 95.5 per cent. All the above results were obtained on fourth day of incubation. Maximum decolourization of azo dyes and mycelium growth of all the three test fungi were favoured on fourth day of incubation. The fungus S. commune efficiently removed acid orange 7 (96.7), methyl red (98.50 %) and evans blue (97.4 %) from the effluent when compared with the other two fungi.
Keywords: Acid orange 7, Methyl red, Evans blue and Effluent.
