The textile industries use different types of dyes in their processing units which are liberated in natural water bodies through wastewater. Disposal of these dyes into the environment causes serious damage. There is the need of era to investigate new bacterial dye degraders that have potential for use in a various textile industries to treat effluents. The present study deals with the degradation of Methyl red (MR) and Carbol fuchsin (CF) by bacteria and its consortium isolated from textile effluents. Three different bacterial spp. were isolated and subjected to dye decolorization assays. The isolated bacteria were capable of decolorizing 0.002 gm/L MR and CF dye. The isolates were identified as Proteus spp., Pseudomonas spp. and Acinetobacter spp. Instead of pure bacterial isolates their consortium was exhibited the highest potential in decolorizing MR and CF up to 100% and 96%, respectively within 24 h. TheComplete degradation of dyes was confirmed by FT-IR analysis.
