Heterotrophic ammonia oxidation by Alcaligenes balances ROS generation and terminal electron transport [PDF]
mLifeHeterotrophic nitrifiers are bacteria that aerobically oxidize ammonia in the presence of organic carbon sources, which differs from autotrophic nitrifiers that extract energy from ammonia oxidation for cell metabolism and growth.

Robust ammonia oxidation by “Candidatus Nitrosacidococcus tergens” across a broad pH range [PDF]
mBioAcidophilic ammonia-oxidizing bacteria (AOB) have only recently been discovered. These organisms hold great promise for acidic wastewater treatment; however, their physiology remains poorly understood compared to that of neutrophilic AOB.

Shifts of ammonia-oxidation process along salinity gradient in an estuarine wetland
Ecological Indicators, 2022 Ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) play an important role in nitrogen (N) cycling of the estuarine sediments. However, the shifts of potential ammonia oxidation rates (PARs) of AOA and AOB along different salinity ...

Nitrification of archaeal ammonia oxidizers in a high- temperature hot spring [PDF]
Biogeosciences, 2016 The oxidation of ammonia by microbes has been shown to occur in diverse natural environments. However, the link of in situ nitrification activity to taxonomic identities of ammonia oxidizers in high-temperature environments remains poorly understood ...
