Azo dyes are the largest group of synthetic aromatic dye used in the textile industry for dyeing purpose and are highly water soluble in nature. The treatment of these dyes have been carried out by many methods such as physical, chemical and biological as individual and in combination to reduce the effect of pollution. The biodegradation of azo dyes is difficult due to the complex structure, synthetic nature and some are highly resistant to microbial attack. This study aims in developing a consortium to degrade complex azo dyes present in the effluent. The current work aims in screening and identification of potent azo dye degrading bacteria, studying azo dye degradation efficiency of the isolates, preparing the microbial consortia and to determine the efficiency in decolourization and degradation in both chosen dye (Amido black 10 B) and effluent. The degradation efficiency of the effluent using mixed dyes were significantly higher than the individual strain which was evident from reduction in colour and COD which was 76 % and 79 % respectively. The degradation of the effluent using consortium was studied using FT-IR which revealed change in the peak characteristics.
