The current research focused on isolation, identification of alkalohalophile the bacteria from the tainted soil samples of effluent treatment plant and their proficiency in degrading melanoidin. A total of four bacteria were selected from the total thirty five isolates and characterized on the basis of decolourization efficiency of melanoidin viz.; A5GS, A9GS, C5 and B9. Preliminary studies showed that A9GS showed 51.4% melanoidin degrading proficiency and identified as Enterobacter sp. as per biochemical studies. The isolate A9GS showed capability to grow on a wide range of salt (NaCl) concentrations ranging 0–10% and upto pH-11.0, indicating halotolerant and alkalophilic nature. Molecular characterization and phylogenetic analysis using 16S rDNA sequence analysis of A9GS showed the similarity to Enterobacter cloacae. To the best of our knowledge E. cloacae is the first report for the melanoidin decolorization from spent wash of molasses distillery effluents.
