Anaerobic ammonium oxidation (anammox) is a microbial process in which NH4+ is
oxidized to N2 gas with NO2− as an electron acceptor. The anammox process is mediated …

Anaerobic ammonium oxidizing (anammox) bacteria can directly convert ammonium and
nitrite to nitrogen gas anaerobically and were responsible for a substantial part of the fixed …

Anammox related technologies are currently widely applied for nitrogen removal from
sewage sludge digester rejection water. Nevertheless, many aspects of the anammox …

Anaerobic ammonium-oxidizing (anammox) bacteria primarily grow by the oxidation of
ammonium coupled to nitrite reduction, using CO2 as the sole carbon source. Although they …

The majority of life on Earth—notably, microbial life—occurs in places that do not receive
sunlight, with the habitats of the oceans being the largest of these reservoirs. Sunlight …

Oxygen minimum zones (OMZs) harbor unique microbial communities that rely on
alternative electron acceptors for respiration. Conditions therein enable an almost complete …

Vast expanses of oxygen-deficient and nitrite-rich water define the major oxygen minimum
zones (OMZs) of the global ocean. They support diverse microbial communities that …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

Nitrate is a key node in the network of the assimilatory and respiratory nitrogen pathways. As
one of the 'fixed'forms of nitrogen, nitrate plays an essential role in both nature and industry …

Microorganisms play important roles in the nitrogen cycles of various ecosystems. Research
has revealed that a greater diversity of microorganisms is involved in the nitrogen cycle than …
