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

Hayati 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.

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.

Ammonia-oxidizing bacteria and archaea within biofilters of a commercial recirculating marine aquaculture system

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.

Diversity of Ammonia Oxidizing Archaea in Tropical Compost Systems

Frontiers in Microbiology, 2012
Composting is widely used to transform waste materials into valuable agricultural products. In the tropics, large quantities of agricultural wastes could be potentially useful in agriculture after composting.

Exploring protein N-glycosylation in ammonia-oxidizing Nitrososphaerota archaea through glycoproteomic analysis

mBio
Ammonia-oxidizing archaea of the phylum Nitrososphaerota, formerly known as Thaumarchaeota, are globally distributed and play critical roles in the nitrogen and carbon cycles, particularly in environments with low ammonia concentrations.

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 ...

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.

Individual and combined contamination of oxytetracycline and cadmium inhibited nitrification by inhibiting ammonia oxidizers

Frontiers in Microbiology, 2022
IntroductionThe large-scale development of animal husbandry and industrialization lead to more and more serious co-contamination from heavy metals and antibiotics in soils.
