Expansion of Thaumarchaeota habitat range is correlated with horizontal transfer of ATPase operons. [PDF]
, 2019 Thaumarchaeota are responsible for a significant fraction of ammonia oxidation in the oceans and in soils that range from alkaline to acidic. However, the adaptive mechanisms underpinning their habitat expansion remain poorly understood.

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 important contributors to this process, particularly in acidic environments.

Ammonia oxidizers in the sea-surface microlayer of a coastal marine inlet. [PDF]
PLoS ONE, 2018 Planktonic archaea are thought to play an important role in ammonia oxidation in marine environments. Data on the distribution, abundance, and diversity of ammonia oxidizers in the coastal sea-surface microlayer (SML) are lacking, despite previous ...

Low yield and abiotic origin of N2O formed by the complete nitrifier Nitrospira inopinata
Nature Communications, 2019 Ammonia-oxidizing bacteria and archaea are major producers of the gases nitrous oxide and nitric oxide. Here, Kits et al. show that a complete ammonia-oxidizing (comammox) bacterium emits nitrous oxide at levels that are comparable to those produced by ...

Ammonia-oxidizing archaea and ammonia-oxidizing bacteria in six full-scale wastewater treatment bioreactors [PDF]
Applied Microbiology and Biotechnology, 2011 In this study, dideoxy sequencing and 454 high-throughput sequencing were used to analyze diversities of the ammonia monooxygenase (amoA) genes and the 16S rRNA genes of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in six municipal wastewater treatment plants.

Microbial community changes along the active seepage site of one cold seep in the Red Sea
Frontiers in Microbiology, 2015 The active seepage of the marine cold seeps could be a critical process for the exchange of energy between the submerged geosphere and the sea floor environment through organic-rich fluids, potentially even affecting surrounding microbial habitats ...

Responses of Ammonia-Oxidizing Microorganisms to Intercropping Systems in Different Seasons
Agriculture, 2021 Intercropping plays an essential role in agricultural production, impacting the soil’s physical and chemical properties and microbial communities. However, the responses of ammonia-oxidizing microorganisms in the continuous-cropping soil to different ...
