The textile dye industries consume a substantial amount of water and produce expansive amount of waste which is contaminated by dyes like reactive dyes, azo dyes, many types of aerosols and much more non-degradable waste materials. The toxic effects of dyestuff and other organic compounds from modern effluents are harsh on human beings and also for regular habitat. Currently, most of the available dyes are aromatic and heterocyclic compounds with complex functional groups that can be converted into aromatic amines which are proved to be carcinogenic. In this research work, bacterial strains which are proficient to decolorize the commercial dye–reactive red were screened out from the soil samples collected from adjacent territories of the textile industry located in Rajkot, India. The reactive red dye decolorization was analyzed using UV-visible spectrophotometric analysis at Æ›max 680 nm. Optimization studies indicated that isolate 1 was found to be Gram positive rods that showed maximum decolorization at 60 hour with 250 mg/L reactive red dye concentration at 40 ºC with pH 5.5 Similarly, Isolate 2 which was Gram negative bacteria exhibited superior decolorization at 60 hours with 250 mg/L dye concentration at 36 ºC with pH 6. Both the isolates showed highest dye decolorization with sucrose as carbon source. Bacterial isolates screened as potential decolorizer of Reactive Red dye, as indicated in the present study can further be exploited for commercial applications towards treatment of industrial effluent contaminated with hazardous dyes.
