Abstract:

Textile and other dye-stuff industries discharge various synthetic dyes into their effluent. The release of these synthetic dyes into the environment is a matter of concern due to the toxicity, mutagenicity, carcinogenicity and xenobiotic nature and causes serious pollution of soil, water & environment. The present study demonstrates the decolorization of three structurally different textile azo dyes (i.e. Reactive green-19 (RG-19). Remazol navy blue (RNB) and Reactive red-198 (RR-198)) using the isolated strain Enterococcus durans GM13 from textile industry waste water. The acclimatized strain was capable of decolorizing all the dyes in a wide concentration range and maximum decolorization efficiency has been achieved with 100 mg/L dye concentration. At 100 mg/L dye concentration, the organism was capable of decolorizing 87% RG-19, 91.3% RNB and 92% RR-198 dye within 24hr of incubation under static condition. Effect of different physico-chemical parameters on the decolorization efficiency of the isolated strain has been studied to achieve maximum decolorization efficiency. Biodegradation of the three model dyes were confirmed through UV-Vis spectral analysis.
