Eco-Friendly Biodegradation and Detoxification of Acid Red-88 textile dye by Textile Effluent Acclimatized Bacterial strain AR-1

Environmental bioengineering is continuously escalating its efforts in the biotic treatment of textile effluents, which is an ecologically friendly and affordable alternative to physico-chemical putrefaction processes. In the present study, effluent samples were collected from various textile and dyeing industries located in and around Tiruvannamalai, Tamilnadu, India and were exploited for the screening and isolation of bacterial strains that were capable of decolorizing the textile dye, Acid Red-88. Optimization of cultural conditions (Temperature, pH, Agitation speeds and Dye concentrations) were carried out to maximize the decolorization efficiency of AR-1 towards Acid Red-88. Decolorization efficiency was found to be optimized at 35°C, neutral pH, after 24 h of incubation. Static conditions proved to be effective in maximizing decolorization. Increase in dye concentration decreased decolorization efficiency of AR-1. Detoxification of Acid Red-88 textile dye by AR-1 was confirmed by Phytotoxicity studies on Macrotyloma uniflorum.
