Abstract: The dye decolorizing isolates Bacillus sp and Pseudomonas sp were isolated from textile effluent sample collected from Erode, Tamilnadu. Different parameters such as pH, temperature, different concentration of dye, carbon source, Nitrogen source and different incubation periods were optimized for decolorization of reactive red M5B by using bacterial isolates. The optimal condition for decolorization of reactive red M5B for both Bacillus sp and Pseudomonas sp was found to be 1% glucose, 1% peptone, pH 7.0, 37⁰c, 1% dye concentration. Bacillus sp and Pseudomonas showed highest decolourization of 76% and 79% at the end of 96hrs under optimum condition. The present study concluded that bacterial isolates like Bacillus sp and Pseudomonas sp can be used as good microbial source for treatment.
