Photoferrotrophy, the process by which inorganic carbon is fixed into organic matter using
light as an energy source and reduced iron [Fe (II)] as an electron donor, has been proposed …

The atmospheric concentration of methane (CH4), a major greenhouse gas, is mainly
controlled by the activities of methane-producing (methanogens) and methane-consuming …

Hydrothermal venting and the formation of carbonate chimneys in the Lost City hydrothermal
field (LCHF) are driven predominantly by serpentinization reactions and cooling of mantle …

Pyrite, or iron disulfide, is the most common sulfide mineral on the Earth's surface and is
widespread through the geological record. Because sulfides are mainly produced by sulfate …

Summary The Black Sea, with its highly sulfidic water column, is the largest anoxic basin in
the world. Within its sediments, the mineralization of organic matter occurs essentially …

In order to better understand the main factors that influence the distribution of sulfate‐
reducing bacteria (SRB), their population size and their metabolic activity in high‐and low …

Abstract In Lake Matano, Indonesia, the world's largest known ferruginous basin, more than
50% of authigenic organic matter is degraded through methanogenesis, despite high …

The availabilities of iron and phosphorus have considerably impacted biological productivity
in past and present natural aquatic environments, and therefore have been key regulators of …

For lake microbes, water column mixing acts as a disturbance because it homogenizes
thermal and chemical gradients known to define the distributions of microbial taxa. Our first …

Lake Pavin is a meromictic crater lake located in the French Massif Central area. In this
ecosystem, most methane (CH4) produced in high quantity in the anoxic bottom layers, and …
