Selective Enrichment of Nitrososphaera viennensis-Like Ammonia-Oxidizing Archaea over Ammonia-Oxidizing Bacteria from Drinking Water Biofilms [PDF]
Microbiology Spectrum, 2022 Ammonia-oxidizing archaea (AOA) can oxidize ammonia to nitrite for energy gain. They have been detected in chloraminated drinking water distribution systems (DWDS) along with the more common ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria

Occurrence of ammonia-oxidizing archaea in wastewater treatment plant bioreactors [PDF]
Applied and Environmental Microbiology, 2006 We report molecular evidence that ammonia-oxidizing archaea (AOA) occur in activated sludge bioreactors used to remove ammonia from wastewater. Using PCR primers targeting archaeal ammonia monooxygenase subunit A (amoA) genes, we retrieved and compared ...

Production of oceanic nitrous oxide by ammonia-oxidizing archaea [PDF]
Biogeosciences, 2012 The recent finding that microbial ammonia oxidation in the ocean is performed by archaea to a greater extent than by bacteria has drastically changed the view on oceanic nitrification.

Freshwater Ammonia-Oxidizing Archaea Retain amoA mRNA and 16S rRNA during Ammonia Starvation
Life, 2015 In their natural habitats, microorganisms are often exposed to periods of starvation if their substrates for energy generation or other nutrients are limiting.

AMB Express, 2018 While biofilters are widely used to metabolize ammonia and other wastes in marine recirculating aquaculture systems, the ammonia-oxidizing bacterial and archaeal communities have not been characterized across a diversity of production systems.

Ammonia-Oxidizing Archaea Dominate Ammonia-Oxidizing Communities within Alkaline Cave Sediments
Geomicrobiology Journal, 2016 Nitrification represents one of the key steps in the global nitrogen cycle. While originally considered an exclusive metabolic capability of bacteria, the identification of the Thaumarchaeota revealed that ammonia-oxidizing archaea (AOA) are also ...

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 ...

Diversity and mode of transmission of ammonia-oxidizing archaea in marine sponges
Environmental Microbiology, 2008 The model marine crenarchaeote ‘Cenarchaeum symbiosum’ is until now the only ammonia-oxidizing archaeon known from a marine sponge. Here, phylogenetic analyses based on the 16S rRNA and ammonia monooxygenase subunit A (amoA) genes revealed the presence ...

Structural and functional microbial diversity of sandy soil under cropland and grassland [PDF]
PeerJ, 2020 Background Land use change significantly alters soil organic carbon content and the microbial community. Therefore, in the present study, the effect of changing cropland to grassland on structural and functional soil microbial diversity was evaluated ...
