N2  - Wastewater originating from the textile industry is one of the major sources of pollution for surface and groundwater bodies in countries where textiles and other dye-products are produced. In this study, the decolorization and degradation of azo dye, Congo Red (CR), and anthraquinone, Disperse Blue 3 (DB3), by different bacterial strains isolated from contaminated sites was investigated. The most potent bacterial strains in decolorization of CR and DB3 were Bacillus cereus MAM-B11, Bacillus cereus MAM-B22, Ochrobactrum sp. MAM-C9 and Achromobacter xylosoxidans MAM-29. The maximum decolorization of CR was observed by B. cereus MAM-B22 which removed 96.92% of 25 mg/L CR and 66.73% of 400 mg/L CR after 3 days of incubation at 37{u00B0}C. The maximum decolorization of DB3 was observed by B. cereus MAM-B11 which removed 97.86% of 25 mg/L DB3 and 73.29% of 400 mg/L DB3 after 3 days of incubation at 37{u00B0}C. The maximum removal of CR was observed at pH 7 with the strain Ochrobacterum sp. MAM-C9 which was 90.21% followed by B. cereus MAM-B22 and A. xylosoxidans MAM-29 which removed 90.03% and 89.62% respectively; while the lowest removal was observed with B. cereus MAM-B11 which was 85.84%; while the maximum decolorization of DB3 was observed at pH 8.0 which was 94.94%, 93.06%, 92.20% and 89.88% by B. cereus MAM-B11, A. xylosoxidans MAM-29, Ochrobacterum sp. MAM-C9 and B. cereus MAM-B22 respectively
