Novel anammox bacteria and nitrogen loss from Lake Superior. [PDF]

Sci Rep, 2017
AbstractAnaerobic ammonium oxidizing (anammox) bacteria own a central position in the global N-cycle, as they have the ability to oxidize NH4+ to N2 under anoxic conditions using NO2−. They are responsible for up to 50% of all N2 released from marine ecosystems into the atmosphere and are thus indispensible for balancing the activity of N-fixing ...

Physiological function and catalytic versatility of bacterial multihaem cytochromescinvolved in nitrogen and sulfur cycling [PDF]

, 2011
Bacterial MCCs (multihaem cytochromes c) represent widespread respiratory electron-transfer proteins. In addition, some of them convert substrates such as nitrite, hydroxylamine, nitric oxide, hydrazine, sulfite, thiosulfate or hydrogen peroxide. In many

Enrichment of marine anammox bacteria in Hiroshima Bay sediments [PDF]

Water Science and Technology, 2011
Anaerobic ammonium oxidation (anammox) involves the microbiological oxidation of ammonium with nitrite as the electron acceptor and dinitrogen gas as the main product. The Scalindua species, an anammox genus that dominates natural habitats, plays an important role in catalysing the loss of nitrogen from marine environments.

Invasion moving boundary problem for a biofilm reactor model

, 2017
The work presents the analysis of the free boundary value problem related to the invasion model of new species in biofilm reactors. In the framework of continuum approach to mathematical modelling of biofilm growth, the problem consists of a system of ...

Light-driven ammonium oxidation to dinitrogen gas by self-photosensitized biohybrid anammox systems

iScience, 2023
Summary: The anaerobic ammonium oxidation (anammox) process exerts a very vital role in the global nitrogen cycle (estimated to contribute 30%–50% N2 production in the oceans) and presents superiority in water/wastewater nitrogen removal performance ...

Microbial competition among anammox bacteria in nitrite-limited bioreactors [PDF]

Water Research, 2017
Phylogenetically diverse anammox bacteria have been detected in most of anoxic natural and engineered ecosystems and thus regarded as key players in the global nitrogen cycle. However, ecological niche differentiation of anammox bacteria remains unresolved despite its ecological and practical importance.
