Azo dyes are composed of pollutants such as suspended solids and toxic materials. These dyes are discharged into waterbodies without any treatment. Thisalters the quality and physico – chemical parameters of water.Therefore, the water is unfit for consumption and the flora and fauna inhabiting suchfresh water bodies are severely affected. In order to reduce toxicants in textile azo dye effluent suitable microbes which can tolerate wide environmental conditions areused.Thehalophilic bacterial strains isolated from solar salt pans have the capacity to degrade the selected diazo dye Congo red. The present study was conducted to investigate the degradation of Congo red dye effluent by using halo bacteria Brevibacillus sp. This halo bacterium was inoculated into the flask containing Congo red dye effluent and incubated for 5 days.TheBrevibacillus sp. treated diazo Congo red dye effluent showed reduction of impurities such as pH 13.33 ± 0.03%, temperature 9.09± 00 %, BOD 61.29± 12.65 %, COD 49.91 ± 22.94 %, TDS 57.43 ± 48.11 %, chloride 42.61 ± 39.73 % and total hardness 48.73 ± 40.64 % when compared to raw dye effluent.
