BIODEGRADATION OF AZO DYE (REACTIVE GREEN 19) BY Pseudomonas aeruginosa ISOLATED FROM TEXTILE EFFLUENT


 Azo dyes are widely used in the textile industry. The release of these undesirable dye effluents to environment can be toxic and carcinogenic towards humans other organisms. removal dyestuff wastes using biodegradation method is consider eco-friendlier compared physical chemical methods. Thus, this study was conducted identify analyze activity azo by potential bacteria isolated from effluent. For decolorization analysis, were inoculated into flasks containing mineral salt medium added with Reactive Green 19 (50 mg/L) incubated for 9 days at 37°C. Spectrophotometry analysis carried out 635 nm level degradation. From we found that optimum pH, temperature, concentration detected pH 7, 37°C, 50 mg/L, respectively. identified Pseudomonas aeruginosa showed 94% after incubation. result bacterial strain biological treatment
