Abstract

Toxic metal contamination in soils due industrialization is nowadays a concern to the scientists worldwide. The current study deals with the evaluation of response and tolerance by isolated metallophilic bacteria in different lead concentrations (100 ppm to 1000 ppm). By taking optical densities of the isolates, the minimum inhibitory concentration (MIC) of Pb were determined.16S rRNA and MALDI-TOF MS were used for the identification of the bacteria. Total of 37 isolates were observed, among them 04 (, and ), isolated were detected having efficacy of Pbtolerance and sequestration at varying MIC. Furthermore, was observed to have highest (900 ppm) tolerance for lead and lowest (500 ppm) for Moreover, the highest (65.3%) sequestration potential has been observed for and least (52.8%) for The tolerance and sequestration potential properties of these isolated species can be utilised to exterminate heavy metals and reduce their toxicity from the contaminated environment.
