Abstract

  The textile and dye industry is an important sector of the chemical industry. These industries generate large volume of waste water. Largest user of azo dyes is textile industry. These recalcitrant dyes are extensively used in cosmetics, pharmaceuticals, printing etc. The waste water generated from these industries has been treated by physical, chemical and biological methods. These effluents show variation in their composition according to the dye used or manufactured which makes the treatment intricate. Treatment of dye industry effluent is a challenging task before its disposal into water bodies. Direct Red 81 was selected for decolourization and detoxification studies by Pseudomonas Aeruginosa strain MZA 85. Dye decolorization and optimization of parameters were carried out under stationary condition. Under optimum conditions the isolate was found to decolorize 94.66% in 13 hrs at pH 7and at 28°C under static condition. Degradation products were analyzed by UV-Visbile spectroscopy, TLC and HPLC. The isolate was also able to decolourize and degrade five dyes under study.

  Hence this indigenous isolate could be a potential organism for bioremediation of wastewater carrying dyes.
