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