The current work is aimed to evaluate the degradation of Reactive Yellow Dye by Pleurotus pulmonarius (a whit rot fungus). The induction of the lignolytic enzyme activities of the organism during the decolorization of reactive yellow suggests their probable role in the biodegradation process. Metabolites obtained after decolorization were analyzed with GC-MS and FTIR studies which confirmed the biodegradation of the dye. Metabolites produced after biodegradation of reactive yellow were identified by GC-MS analysis. Predicted pathway of biodegradation of reactive yellow by Pleurotus pulmonarius was elucidated for first time. The results showed efficient biodegradation of reactive yellow to low molecular weight compounds, namely, 2-methyl 3-hydroxypyrone; 1-hydroxy 2,4dichloro benzene; 4-hepten-3-one, 3-chloro-4-methyl-2-pentanol; 4,hydroxyphenethyl alcohol; 1,6-anhydro-beta d-glucopyranose and fatty acids. Pleurotus pulmonarius was found to be versatile and could be used for textile effluent biodegradation and consequently environmental bioremediation.
