ABSTRACT: The study was carried out to know significant involvement by uncovering the ability of native microbes isolated from the sample obtained from textile industry for decolorization and degradation of dyes and effluent through Isolated bacterial strains these were identified, through 16S rRNA Sequence analysis and confirmed the strains as, Bacillus cereus and Bacillus sp. The degraded metabolites were detected through HPLC (high performance liquid chromatography) analysis based on the retention time and the functional groups were detected through fourier transform infrared spectroscopy and the decolorization was carried through UV-visible spectroscopy by using the absorbance. The decolorization time required for decolorization was less in the consortia than the individual species these individual species were able to mineralize dyes. The SEM analysis revealed the consortium as tight clumps. The phytotoxicity results seed germination test with Vigna radiata reveals the positive results after the treatment through the consortium over the raw effluent.
