Bacterial Decolourization of Acid Orange 10 in Synthetic Wastewater under Saline Conditions: Effect of Process Parameters
C.J. Ogugbue, F. Akubuenyi and A.A. Ibiene

Abstract:
The decolourization of Acid orange 10 in Synthetic Saline Wastewater (SSW) medium under static conditions was investigated using Bacillus firmus. The bacterium was able to effectively decolourize the azo dye in a wide range of salt (NaCl) concentrations (1 to 6%, w/v), temperature (20-40°C) and pH (6-10) after 24 h of incubation in static culture. Colour removal by this strain was enhanced in the presence of starch and considerable decolourization was obtained in medium with high salt concentration (6%) in the presence of SDS (0.5-50 mg L-1). Results suggest the potential of this halotolerant bacterium for use in effective treatment of dye-contaminated wastewaters containing high salt concentrations characteristic of typical textile effluents.
