Diversity and Abundance of Ammonia-Oxidizing Bacteria and Archaea in a Freshwater Recirculating Aquaculture System

open access: yesHayati Journal of Biosciences, 2017
The role of ammonia-oxidizing bacteria and archaea was evaluated using amoA gene in a freshwater recirculating system. Broken earthen pot pieces (BEP) were used as filter bed material.

Ammonia-Oxidizing Archaea Dominate Ammonia-Oxidizing Communities within Alkaline Cave Sediments

open access: yesGeomicrobiology 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]

open access: yesPLoS 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

open access: yesNature 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 ...

Microbial community changes along the active seepage site of one cold seep in the Red Sea

open access: yesFrontiers 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

open access: yesAgriculture, 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 ...

Population Dynamics and Community Composition of Ammonia Oxidizers in Salt Marshes after the Deepwater Horizon Oil Spill [PDF]

open access: yes, 2016
The recent oil spill in the Gulf of Mexico had significant effects on microbial communities in the Gulf, but impacts on nitrifying communities in adjacent salt marshes have not been investigated.

Nitrogen and Phosphorus Fertilization Reshapes the Abundance and Structure of Ammonia Oxidizers on a Leymus chinensis Steppe in Northern China

open access: yesAgronomy, 2022
Although nitrogen (N) and phosphorus (P) fertilization are important for maintaining the health and productivity of Leymus chinensis steppe, their impact on the abundance and community structure of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing ...

Ammonia-oxidizing archaea and ammonia-oxidizing bacteria in six full-scale wastewater treatment bioreactors [PDF]

open access: yesApplied 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.
