Shewanella oneidensis MR-1 produced electrically conductive pilus-like appendages called
bacterial nanowires in direct response to electron-acceptor limitation. Mutants deficient in …

Methylmercury is a potent neurotoxin produced in natural environments from inorganic
mercury by anaerobic bacteria. However, until now the genes and proteins involved have …

Microbial mercury (Hg) methylation transforms a toxic trace metal into the highly bioaccumulated
neurotoxin methylmercury (MeHg). The lack of a genetic marker for microbial MeHg …

Mercury (Hg) methylation produces the neurotoxic, highly bioaccumulative methylmercury (MeHg).
The highly conserved nature of the recently identified Hg methylation genes hgcAB …

We propose the use of Desulfovibrio desulfuricans ND132 as a model species for understanding
the mechanism of microbial Hg methylation. Strain ND132 is an anaerobic dissimilatory …

Soils contain a tangle of minerals, water, nutrients, gases, plant roots, decaying organic
matter, and microorganisms which work together to cycle nutrients and support terrestrial plant …

Shewanella oneidensis MR-1 is a facultatively anaerobic bacterium capable of using
soluble and insoluble forms of manganese [Mn(III/IV)] and iron [Fe(III)] as terminal electron …

Biological sensors can be engineered to measure a wide range of environmental conditions.
Here we show that statistical analysis of DNA from natural microbial communities can be …

Methylmercury is a neurotoxin that poses significant health risks to humans. Some anaerobic
sulphate- and iron-reducing bacteria can methylate oxidized forms of mercury, generating …

Considering that 25% of Earth’s terrestrial surface is underlain by permafrost (ground that
has been continuously frozen for at least 2 years), our understanding of the diversity of …
