英文摘要: Mercury (Hg), a global pollutant produced by anthropogenic and natural means acts as a bioacumulative toxin that severely affects our environment and human lives. Besides being a potent neurotoxin, mercury has several adverse effects on all the major body systems. Mercury changes its chemical forms in the environment and travels from place to place and finally it gets deposited deep down into soil and sediments. As mercury remediation through conventional approaches is costly and technically difficult, bioremediation is a more cost-effective, eco-friendly method and accepted by regulatory authorities. This paper emphasizes on the recent developments in the biochemical mechanism of mer operon and its utilization in mercury bioremediation. This review also focuses on the use of mercury resistant bacteria (MRB) for the remediation of mercury-contaminated sites. Furthermore, the role of yeast in mercury bioremediation has also been listed. Moreover, we have focused on the detailed application of whole-cell biosensor, nanotechnology, phytoremediation, plant-assisted microbial remediation and significance of modern biotechnological techniques such as transposon-mediated In-situ molecular breeding (ISMoB) for effective removal of mercury. Conclusively, this review enhances the detailed understanding of mercury bioremediation scenarios on a global scale in recent times. © 2020 Elsevier B.V. Citation statistics:
