Abstract Mercury (Hg) methylation, methylmercury (MeHg) demethylation, and inorganic
redox transformations of Hg are microbe-mediating processes that determine the fate and …

The gene pair hgcAB is essential for microbial mercury methylation. Our understanding of its
abundance and diversity in nature is rapidly evolving. In this study we developed a new …

Human‐induced expansion of oxygen‐deficient zones can have dramatic impacts on marine
systems and its resident biota. One example is the formation of the potent neurotoxic …

Mercury (Hg) methylation genes (hgcAB) mediate the formation of the toxic methylmercury
and have been identified from diverse environments, including freshwater and marine …

Climate change dramatically impacts Arctic and subarctic regions, inducing shifts in wetland
nutrient regimes as a consequence of thawing permafrost. Altered hydrological regimes may …

Mercury (Hg) adversely affects human and environmental health. To evaluate the mercury
(Hg) speciation (methylation, demethylation, and reduction) of microorganisms in coastal …

Highly neurotoxic methylmercury (MeHg) accumulates in marine organisms, thereby
negatively affecting human and environmental health. Recent studies have revealed that …

Scant attention has been paid to cycling of total mercury (THg) and methylmercury (MeHg) in
agriculturally intensive watersheds. Monitoring of Hg and MeHg in river basins provides …

The most abundant known nitrite-oxidizing bacteria in the marine water column belong to
the phylum Nitrospinota. Despite their importance in marine nitrogen cycling and primary …

Marine prokaryotes are involved in mercury (Hg) speciation in marine environments.
However, information regarding the specific microbial lineages contributing to Hg speciation …
