Discharge of textile effluent into open environment is serious environmental problem and the color removal of wastewater is major environmental concern. Azo Dyes are the largest class of aromatic dyes having lots of commercial interest. These dyes are carcinogenic both for animal and human beings. Biological treatment either by bacteria, fungi or consortia of both have been reported to reduce the toxicity of the dye to the permissible limit of discharge to the environment. This review demonstrates the importance of microorganisms to reduce these azo dyes and protect the environment from the devastating effect of these dyes. The documents talks about different microbes and methods used to degrade the dyes, while comparing their performance to established physical/chemical textile wastewater treatment practises. Utilization of microorganism consortia offers considerable advantages over the use of pure cultures in the degradation of synthetic textile dyes, instead of pure cultures, higher degrees of biodegradation and mineralization can be achieved due to synergistic metabolic activities of the microbial community.Consortia usually do not require sterile conditions and have greater stability towards changes in the prevailing conditions(pH, temperature and feed composition) compared with pure cultures. Therefore, the use of mixed cultures is a good strategy for bioreactors.
