ABSTRACT
In the present study, Pseudomonas putida strain, a mercury resistant bacterium, which is able to reduce ionic mercury to metallic mercury was isolated from chloralkali wastewater and used to remediate ion mercury in liquid medium.The bacterium exhibits high Minimal Inhibitory Concentrations (MICs) for mercuric Chloride. Removal of mercuric chloride by Pseudomonas putida was studied using pepton water medium in the concentration range 1-120 mg L -1. Two processes, adsorption on the cell surface and bioaccumulation have been observed. Maximum removal capacity for the bacterium was found to be 98%. Thus, bacterial removal of mercury is a potential biological treatment for mercury environmental pollutants
