Problem statement: The textile industries use different types of dyes in their processing units which are liberated in natural marine water bodies. This release of dyes in turn affect the marine flora and fauna very adversely. Approach: The release of textile dyes into the environment is a matter of concern due to the toxicity, mutagenicity, carcinogenicity and xenobiotic nature. Hence, considerable attention has been given in determining the ability of marine microorganism in decolorization and degradation of textile dyes. Results: The present study deals with the decolorization of Mordant Orange-1 was carried out using the acclimatized Marinobacter algicola MO-17 isolated from natural marine environment. The acclimatized strain was capable of decolorizing 800 μg mL -1 of the dye at high salt concentration (12%) in 24 h. The percent decolorization of the dye was moderated by spectroscopy at 385 nm (λmax). Conclusion/Recommendations: The spectrophotometric analysis showed 78.78% decolorization in Nutrient Broth and 76.78% decolorization in Half Strength Nutrient Broth. The percent Chemical Oxygen Demand (COD) reduction of the dye by the strain was 90%. From the study performed, we conclude that, this acclimatized strain can prove better option for bioremediation of textile dyes in wastes containing high salts and in marine environment. © 2012 Science Publications.
