The textile industry is known to use massive amount of dyes to colour fabrics and subsequently the treatment of textile effluent is one of the greatest challenge. The aim of this research is to investigate the ability of the bacterial consortium to decolourise congo red dye. The synergy effects of microbial consortium offer considerable advantages over single culture in mineralisation of complex dye compounds. The consortia were developed by using isolated strain of Bacillus sp. named as AMS-XI and AMS-XIII from soil sample near the textile effluent. Environmental parameters such as pH, salt, dye concentration, medium optimization (carbon and nitrogen sources), shaking condition were optimized by using yeast malt broth medium containing different concentration of Congo red dye (50 ppm and 100ppm). Maximum decolorizing efficiency was observed in a yeast malt broth medium containing 50ppm of congo red dye, sucrose, sodium nitrate, of bacterial consortium Bacillus sp. observed under 14 hours at temperature 37°C pH 7.0 and static conditions. Kinetics of % decolorization showed the 99.11% in 14 hours by bacterial consortium and biomass concentration of consortium 0.15gm/ml was observed after 22 hours. TLC technique and proton NMR spectral analysis were also done and some esters, aliphatic and aromatic compounds were detected after decolorization. Industrial effluent treatment assay was done. It was observed that 76.68% COD removed after degradation in 10 hours. In future consortium can successfully be employed in the treatment of textile effluent.
