摘要：

Aeromonas hydrophila isolate showed the best decolorization of Reactive Black 5 (RB5) at the concentration of 100 mg L-1 on modified mineral salt medium among 42 bacterial isolates. Optimization of parameters for RB5 dye decolourization was studied under static condition. Under optimized condition, decolorization efficiency of RB5 by A. hydrophila was found to be 76% at 100 mg L-1 within 24 h. The optimum pH and temperature for the decolorization was 7 and 35 degrees C respectively. Biodegradation and decolorization of RB5, was monitored by UV-Vis spectrophotometry, Thin Layer Chromatography, Fourier Transform Infrared Spectroscopy and Gas Chromatography Mass Spectrometry analysis. The study has confirmed the potential of A. hydrophila isolated from textile effluent in degradation of RB5 and opened scope for future analysis in the treatment of textile effluent.
