Six textile dyes were selected for decolorization tests, these were Red ME6BL, Orange ME2RL, Turquoise Blue BGF, Turquoise Blue RSPL,Yellow 4G and Green 3R. 85 strains were isolated from the textile dyeing effluents and finally 25 strains were selected on the basis of their decolorization potentiality. Selected 25 isolates were studied in detail for provisional identification. Out of 25 isolates 21 were Gram positive and 4 were Gram negative aerobic bacteria. . Out of 25 strains only 2 strains viz. Bacillus cereus and B. subtilis were able to decolorize Red ME6BL and Orange ME2RL within 16 hours. Most of the strains were also capable of decolourizing Red ME6BL, Orange ME2RL, Turquoise Blue BGF, Turquoise Blue BGF in mono culture within 3-5 days. In mixed culture Red ME6BL, Orange ME2RL,Turquoise Blue BGF were decolourized within 2-3 days.Textile Waste water samples used as inocula were capable to decolourize selected six dye compounds within 24 hrs.
