The ocean is home to a diverse and metabolically versatile microbial community that
performs the complex biochemical transformations that drive the nitrogen cycle, including …

The traditional biological nitrogen removal (BNR) follows the conventional scheme of
sequential nitrification and denitrification. In recent years, novel processes such as …

Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Heavy metal contamination of soil has become a serious global issue because of their
persistence in the environment and the non-biodegradable nature leading to their …

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 …

Oceanic anoxic events (OAEs) record profound changes in the climatic and
paleoceanographic state of the planet and represent major disturbances in the global …

The anaerobic ammonium oxidation (anammox) process is well-known as a low-energy
consuming and eco-friendly technology for treating nitrogen-rich wastewater. Although the …

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 …

Dissolved oxygen concentration is a crucial organizing principle in marine ecosystems. As
oxygen levels decline, energy is increasingly diverted away from higher trophic levels into …
