Use of textile dyes is becoming extensively easy in the textile industry because of their wide variety and varied applications. A large quantity of commercially available dyes is known to be used in the textile industries today and 10 % of nearly a million tons of dyes that are produced are released in environment as dyestuff waste. These dyes when disposed into the environment causes pollution and serious irreversible damage to the ecosystem as they significantly affect the photosynthetic activity of aquatic plants and are also toxic to aquatic organisms which eventually get into the food chain. In the present study the bacteria were isolated from samples collected from various textile industry effluent samples and were assayed for its dye degradation ability. The bacterial isolates which were capable of complete degradation of the dye were identified by morphological and biochemical characterization. The activity of these bacteria on different dyes for maximum degradation was tested using different physical parameters like different pH, temp and Dye concentration. The test organism Pseudomonas aeruginosa showed maximum dye degradation on the 8th day of incubation at 40 mg/l of dye concentration. The test organism showed maximum degradation at 40oC, and a optimal pH of 6.0 to 8.0. In the present investigation Pseudomonas aeruginosa was found to be capable of maximum degradation of all the dye samples. The present study reveals the practical application potential of using bacterial species in the bioremediation of dye effluents that can be used to reduce pollution caused by textile industries.
