Redox Transformations of Hg by Anaerobic Enrichments

摘要：

While microbial mercury (Hg) reduction has been extensively studied in aerobic resistant prokaryotes carrying mer operons capable of reducing Hg(EI) to Hg(0), little is known about mer activities among anaerobes and in anoxic zones. It has been suggested that Hg-contaminated groundwater, which may be super-saturated with Hg(0), may result from stimulation of microbial activities in subsurface environments. Given that in situ bio-remedial action which conventionally relies on strategies that enhance indigenous microbial degradation and transformation of pollutants in contaminated subsurface sediments might inadvertently mobilize Hg into groundwater, a better understanding of the processes mediated by anaerobic microbial consortia that control the mobility of Hg in aquifers is crucial for future environmental management and remediation efforts.
