Abstract:
Azo dye Reactive Red 195 was selected for decolourization and degradation studies by Georgenia sp.CC-NMPT-T3. Optimization of parameters for dye decolourization was studied under static anoxic condition. Under optimized condition decolourization of Reactive Red 195 by Georgenia sp.CC-NMPT-T3 was found to be 95.93 % at 50 mg/L within five hours in static anoxic condition. The optimum pH and temperature for the decolourization was 7.0 and 40 degrees C respectively. The biodegradation was monitored by UV-Vis, and TLC and HPLC. Toxicity study demonstrated no toxicity of the biodegraded product. The results suggest that the isolated organism Georgenia sp.CC-NMPT-T3 as a useful tool to treat wastewater containing reactive dyes.
