Efficacy of bacterial consortium in bioremediation of textile effluent of Sanganer Jaipur

Abstract

Inexhaustible use of natural resources is a pattern of straight approach to meet newlineanthropogenic requirements for basic and commercial needs. Rapidly developing textile newlineindustrialisation in Sanganer, Jaipur, is the cause of the generation of several xenobiotic newlineeffluents, as CETP is not complying fully. The poor management process and careless newlinewaste disposal practices from textile and dye industries lead to severe environmental newlinemenace. These industries are the prime source for the generation of a frantically higher newlinenumber of industrial effluents, including recalcitrant dyes disrupting several parameters newlinewhich were beyond the permissible limit given by the Central Pollution Control Board newline(CPCB), which results in ecological balance and creating an environmental hazard. newlineCurrent management practices are mainly based on physical and chemical approaches newlinethat cannot eradicate effluents safely. The current study depicts the collection of newlinewastewater samples from two dyeing discharge sites in Sanganer, Jaipur, Rajasthan. newlineThe screened bacterial isolates showed significant decolorization of both the effluent newlinesamples, identified by morphological and biochemical tests using the Automated newlineMicrobial Identification System, VITEK-2 test. A dye degradation assay for both newlinesamples followed the analysis further. In that context, the present study aims to newlineexamine potent native microbial isolates from untreated wastewater released from newlinetextile industries of the Sanganer area, Jaipur, Rajasthan, India. Analysis was newlineperformed by collecting wastewater samples from two dumping sites, and their newlinephysiochemical evaluation was done using several parameters. Isolates were further newlinescreened based on their capability to decolourize the wastewater. Spectrophotometric newlineanalysis was performed to evaluate the decolorizing assay of the isolates at regular time newlineintervals. Eleven competent bacterial strains, which showed potential degradation newlineefficiency, were screened from these two random discharge sites of textile effluent.
