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

Mercury methylation in aquatic environments is a key process that incorporates this
neurotoxin into the food chain and ultimately the human diet. Mercury methylation is …

Methylmercury (MeHg) is a bioaccumulative toxic contaminant in many ecosystems, but
factors governing its production are poorly understood. Recent work has shown that the …

Environmental contamination by mercury in its organometallic form, methylmercury, remains
a major global concern due to its neurotoxicity, environmental persistence and …

We examined the composition and spatial correlation of sulfur and mercury pools in
peatland soil profiles by measuring sulfur speciation by 1s X-ray absorption near-edge …

Bacteria and archaea possessing the hgcAB gene pair methylate inorganic mercury (Hg) to
form highly toxic methylmercury. HgcA consists of a corrinoid binding domain and a …

The hgcAB gene pair encodes mercury (Hg) methylation capability in a diverse group of
microorganisms, but its evolution and transcriptional regulation remain unknown. Working …

Recent studies have identified HgcAB proteins as being responsible for mercury [Hg (II)]
methylation by certain anaerobic microorganisms. However, it remains controversial …

Background Bacillus cereus is a Gram-positive, spore-forming bacterium that produces a
spectrum of effectors integral to bacterial niche adaptation and the development of various …

Mercury (Hg) is a heavy metal that exhibits high biological toxicity. Monomethylmercury and
dimethylmercury are neurotoxins and a significant environmental concern as they …
