Environmental factors shaping the ecological niches of ammonia-oxidizing archaea [PDF]
FEMS Microbiology Reviews, 2009 For more than 100 years it was believed that bacteria were the only group responsible for the oxidation of ammonia. However, recently, a new strain of archaea bearing a putative ammonia monooxygenase subunit A (amoA) gene and able to oxidize ammonia was ...

Global ecological pattern of ammonia-oxidizing archaea. [PDF]
PLoS ONE, 2013 BACKGROUND: The global distribution of ammonia-oxidizing archaea (AOA), which play a pivotal role in the nitrification process, has been confirmed through numerous ecological studies.

Ammonia-oxidizing archaea have more important role than ammonia-oxidizing bacteria in ammonia oxidation of strongly acidic soils [PDF]
The ISME Journal, 2011 Abstract Increasing evidence demonstrated the involvement of ammonia-oxidizing archaea (AOA) in the global nitrogen cycle, but the relative contributions of AOA and ammonia-oxidizing bacteria (AOB) to ammonia oxidation are still in debate. Previous studies suggest that AOA would be more adapted to ammonia-limited oligotrophic conditions,

Indigenous Ammonia-Oxidizing Archaea in Oxic Subseafloor Oceanic Crust
mSystems, 2020 Oceanic ridge flank systems represent one of the largest and least-explored microbial habitats on Earth. Fundamental ecological questions regarding community activity, recruitment, and succession in this environment remain unanswered.

Alcohols as inhibitors of ammonia oxidizing archaea and bacteria. [PDF]
FEMS Microbiol Lett, 2023 Abstract Ammonia oxidizers are key players in the global nitrogen cycle and are responsible for the oxidation of ammonia to nitrite, which is further oxidized to nitrate by other microorganisms. Their activity can lead to adverse effects on some human-impacted environments, including water pollution through leaching of nitrate and ...

Competition between ammonia-oxidizing archaea and complete ammonia oxidizers from freshwater environments. [PDF]
Appl Environ MicrobiolNitrification is a key process in the global nitrogen cycle. Aerobic ammonia oxidizers play a central role in the nitrogen cycle by performing the first step of nitrification. Ammonia-oxidizing archaea (AOA) and complete ammonia oxidizers (comammox) are the dominant nitrifiers in environments with low ammonium availability.

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 ...
