The decolorization of textile dye effluent samples containing red dye was studied by using some potential bacterial strains (Bacillus sp, Pseudomonas sp, Staphylococcus sp and Enterobacter sp) isolated from the effluent sample.  The isolated bacterial strains was inoculated separately on to the nutrient broth containing the supernatant of dye effluent sample obtained by centrifugation and incubated under controlled conditions for several days (up to 14days). The decolorization in the sample by the inoculated organism was measured spectrophotometrically at regular intervals at 530 nm. Also the chemical oxygen demand for the effluent sample before and after inoculation with the test isolates were measured and the extent of reduction in the organic contaminant (dye) in the sample was calculated.
