Under optimized condition decolorization of Reactive orange by Pseudomonas spp was found to be 98% at 50mg/L within five hours in static anoxic condition. The optimum pH and temperature for the decolorization was 8.0 & 37 ˇăC respectively. The biodegradation was monitored by FTIR analysis. The results suggest that the isolated organism Pseudomonas spp as a useful tool to treat wastewater containing reactive dyes. http://pubs.sciepub.com/ijebb/1/1/1/ijebb-1-1-1.pdf reactive orange Pseudomonas pH temperature static condition
