Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

This paper reviews dissimilatory nitrate reduction to ammonium (DNRA) in soils-a newly
appreciated pathway of nitrogen (N) cycling in the terrestrial ecosystems. The reduction of …

The chemical transformations of methane (CH4) and carbon dioxide (CO2) greenhouse
gases typically have high energy barriers. Here we present an approach of strategic …

Redox-driven biogeochemical element cycles play a central role in converting organic
matter in aquatic ecosystems. They also perform key functions such as removing nitrate …

Iron is the most abundant redox‐active metal in the Earth's crust. The one electron transfer
between the two most common redox states, Fe (II) and Fe (III), plays a role in a huge range …

Cable bacteria are centimeter-long filamentous bacteria that conduct electrons via internal
wires, thus coupling sulfide oxidation in deeper, anoxic sediment with oxygen reduction in …

It is known that the presence of sulfate decreases the methane yield in the anaerobic
digestion systems. Sulfate-reducing bacteria can convert sulfate to hydrogen sulfide …

In natural anoxic environments, anoxygenic photosynthetic bacteria fix CO2 by
photoheterotrophy, photoautotrophy, or syntrophic anaerobic photosynthesis. Here, we …

Location, specific topography, and hydrographic setting together with climate change and
strong anthropogenic pressure are the main factors sha** the biogeochemical functioning …

Reductive dissolution during permafrost thaw releases iron-bound organic carbon to
porewaters, rendering previously stable carbon vulnerable to microbial decomposition and …
