Isolation and Characterization of Bacterial Consortia for Bioremediation of Textile Dye Effluent

The poor management process and negligent waste disposal practices from textile and dye industries lead to severe environmental menace. At present, industrial effluent disposal treatment uses physical and chemical approaches. Hence, an investigation was conducted using potent and native microbial isolates from untreated wastewater released from textile industries in the Sanganer area of Jaipur, Rajasthan, India. Eleven competent bacterial strains, which showed potential degradation efficiency, were screened from these two random discharge sites of textile effluent. The study also developed bacterial consortia 1 (DB1-DB7), which showed a maximum of 87%, and consortia 2 (DR1-DR4), which established a minimum decolorization of 65%. The biochemical analysis and 16S rDNA sequencing were investigated, suggesting that potent organisms and their consortium belong to Bacillus and Pseudomonas spp. In the future, the exploitation of these species would scale up for a safe and efficient bioremediation process..
