Azo dyes are important chemical pollutants of industrial origin. Textile dye effluent sample was collected from Colombia dye chemical processing industry, Rayar Palayam, a dye industry at Palladam Taluk of Tirupur district in Tamilnadu. The sample was collected in a plastic pet bottle. Bio degradation of textile effluent and commercially available Anthraquinone Blue 3R textile dye was studied against the three bacterial isolates such as Bacillus sp., E. coli, and Pseudomonas fluorescens, which have been isolated from the dye effluent sample by pour plate method and the percentage decolourization, was estimated. The medium containing Anthraquinone Blue 3R dye sample (commercial dye) was inoculated with pre-grown bacterial isolates at 1×106 cfu/mL. The disappearance of the colour in the culture medium was monitored by measuring the absorbance wave length at viz. (493 nm, 572 nm, 413 nm, 574 nm, 664 nm) after 0, 4, 8, 12, 16 days of incubation period. Biodegradation of Anthraquinone Blue 3R by the different bacterial isolates at a dye concentration of 2.5% was estimated and the decolourization percentage was tabulated as Pseudomonas fluorescens, showed highest decolourization percentage of 82% and followed by Bacillus sp. (63%) and E. coli (59%) after 16 days of incubation period.
