Wastewater from textile industries poses a high environmental impact and therefore needs to be treated before being discharged into the environment. The present study deals with the decolorization of sulfonated di-azo dye Reactive Red HE8B by different bacterial cultures isolated from a contaminated site. Amongst 19 cultures, the isolate YPAG-9 displayed 86% decolorization of Reactive Red HE8B (100 mg l-1) in 48 h. Based on morphological, cultural, physiological and biochemical properties, the isolate YPAG-9 was identified as Pseudomonas aeruginosa. The color removal efficiency of the isolate was further improved by optimizing various physico-chemical parameters. The decolorization of the dye was 1.9 times higher under static condition as compared to shaking condition. The 10% (v/v) inoculum size, 7.0 pH and 30oC temperature were found optimum for the decolorization of the dye. The isolate was able to decolorize the dye in the range of 50-300 mg l-1. The decolorization of 11 different synthetic dyes was achieved by the isolate YPAG-9. The results suggest the potential application of the isolate YPAG-9 for the bio-treatment of dye containing industrial waste waters.
