Abstract:

The extensive use of fascinating colorful dyes during textile manufacturing indirectly causes severe environmental problem. These dyes exert toxic effects on terrestrial and aquatic life forms, imparting photosynthesis and other metabolic processes. Color is an escalating problem in industrial wastewater. Hence, there is a pressing need to eradicate this contaminant for a sustainable environment. This investigation was directed to isolate and characterized potential bacteria which can efficiently decolorize common recalcitrant textile dye Yellow CRG. Out of 40 bacterial isolates obtained, an isolate was selected and screened out for the study of decolorization of textile dye Yellow CRG. Initial decolorization was recorded as 53.2% by selected bacterial isolate under shake culture condition at 30ºC and pH 7.0. Optimization of culture conditions revealed significant decolorization increase upto 78% with sucrose and ammonium chloride as carbon and nitrogen source. Optimum temperature and pH was 35ºC and 7.0 respectively with 1% inoculum size. Assessment of toxic effect of treated dyes on two important agricultural crops (wheat and mung bean) ensured that bacterium was able to reduce the toxicity of dye through biosorption. Bacterial isolate exhibited potential to decolorize textile dye therefore can be used in wastewater treatment.
