Deciphering chromate tolerance and reduction ability of an indigenous Bacillus strain isolated from polluted pond sludge for chromium bioremediation.

ABSTRACT: Industrial development has caused significant environmental pollution by discharging chromium (Cr) contaminated hazardous effluents into the ecosystem. The main goal of this study was to isolate, characterize, and assess the Cr(VI) resistance potential of indigenous naturally occurring chromate-resistant bacteria from the Uttar Dinajpur region of West Bengal. Based on the maximum tolerable concentration (MTC) to Cr(VI), a potent indigenous bacterial isolate with an MTC of 400 µg mL^- 1 was selected for a detailed assessment of its Cr(VI) tolerance and reducing abilities. Molecular identification and phylogenetics revealed the isolate as a strain of Bacillus wiedmannii. Cr(VI) resistance ability of the isolate in different pH was analyzed, and a Fourier-transform infrared spectros
