Ammonia oxidation and ammonia-oxidizing bacteria and archaea from estuaries with differing histories of hypoxia [PDF]
The ISME Journal, 2007 Nitrification, the oxidation of NH₄⁺ to NO₂⁻ and subsequently to NO₃⁻ , plays a central role in the nitrogen cycle and is often a critical first step in nitrogen removal from estuarine and coastal environments.

A Review of Ammonia-Oxidizing Archaea and Anaerobic Ammonia-Oxidizing Bacteria in the Aquaculture Pond Environment in China [PDF]
Frontiers in Microbiology, 2021 The excessive ammonia produced in pond aquaculture processes cannot be ignored. In this review, we present the distribution and diversity of ammonia-oxidizing archaea (AOA) and anaerobic ammonia-oxidizing bacteria (AnAOB) in the pond environment ...

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.

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 ...

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 ...

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.

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 ...
