Textile industry causes side effects to the environment because of the use of water in processing and producing highly contaminated waste. Recently, biological treatment was applied that used bacteria and other microorganism to remove contaminants in textile wastewater. In the present study, the bacteria Pseudomonas spp. used as an alternative green technology method to decolorize and degrade coractive red dye. A bacterium identified as Pseudomonas spp. was isolated from textile wastewater. The effect of pH and dye concentrations on decolorization was studied to find the optimum conditions required for maximum decolorization. The results show that bacteria is the optimum condition of pH was 7.0 (85.45%) in the neutral region for 48 hours. The bacterium exhibited a remarkable color removal capability over a wide range of dye concentrations (100-500mg/L) at maximum of 89.40% of decolorization for 5 days. Overall, the results indicated that the Pseudomonas spp. was suitable as biological aged used in textile wastewater treatment. Biodegradation and decolorization was confirmed by using UV-VIS spectrophotometry. [ABSTRACT FROM AUTHOR]
