Mercury contamination is becoming more challenging because of the major amount of mercury entering the environment by natural activities. It has been observed that major strains of Pseudomonas species have special clustered genes in an operon i.e. mer operon that easily detoxifies mercury contamination. Even some species of Pseudomonas such Pseudomonas aeruginosa, P. putida are involved in remediation of mercury contamination in plants by phytoremediation phenomenon. The present research examines the role of mercury resistant bacteria in mercury-contaminated soil and includes that bacterium in remediation design. To evaluate this assistance of mercury resistant bacteria, the present work was conducted to determine the role of pseudomonas species in the bioremediation of mercury-contaminated soil. Explore the mer operon and estimate removal of mercury by Pseudomonas spp. and to detect and characterize the mercury reductase enzyme activity produced by a strain. Pseudomonas species were isolated from metal contaminated and pesticide areas. Among all P. species, two highly potent isolates which were resistant to high mercury concentration and able to remove mercury are Pseudomonas aeruginosa and Pseudomonas putida. The bacterial isolate P. aeruginosa showed the highest mercury bio remediating capacity for Hg (II) i.e 85% more than Pseudomonas putida under laboratory conditions. Results of this article illustrate the occurrence of the diverse strain of Pseudomonas, bacteria capable of high tolerance to mercury. The mercury reducing ability shown by Pseudomonas species signified their potential to develop bioremediation technologies and application in remediation of the environment and waste contaminated with mercury.
