A Streptomyces consortium was developed and investigated for biodegradation of reactive sulfonated di azo dye (Reactive Blue 222). The biodegradation of azo blue dye by the consortium was further assesses with different ratios of inoculum of two different Streptomyces potential isolates. The optimization of process conditions was further carried out with respect to the dye concentrations, pH and temperature for the potential Streptomyces consortium. The Streptomyces consortia of 2:1 ratio was prove to enhance the biodegradation of azo blue dye to 89.39%. Dye concentration of 300 mg/L, pH of 7.0 and temperature of 35 °C showed the maximum degradation of 88.33 %, 89.06 % and 89.47 % respectively.
