Community Structure of Ammonia-Oxidizing Archaea and Ammonia-Oxidizing Bacteria in Soil Treated with the Insecticide Imidacloprid [PDF]

BioMed Research International, 2015
The purpose of this experiment was to assess the effect of imidacloprid on the community structure of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in soil using the denaturing gradient gel electrophoresis (DGGE) approach. Analysis showed that AOA and AOB community members were affected by the insecticide treatment.

Drivers of archaeal ammonia-oxidizing communities in soil

Frontiers in Microbiology, 2012
Soil ammonia-oxidizing archaea (AOA) are highly abundant and play an important role in the nitrogen cycle. In addition, AOA have a significant impact on soil quality.

Effect of different ammonia concentrations on community succession of ammonia-oxidizing microorganisms in a simulated paddy soil column. [PDF]

PLoS ONE, 2012
Ammonia oxidation is performed by both ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). To explore the effect of ammonia concentration on the population dynamic changes of ammonia-oxidizing microorganisms, we examined changes in the ...

Influence of oxygen availability on the activities of ammonia‐oxidizing archaea

Environmental Microbiology Reports, 2017
Summary Recent studies point to the importance of oxygen (O 2 ) in controlling the distribution and activity of marine ammonia‐oxidizing archaea (AOA), one of the most abundant prokaryotes in the ocean. The AOA are associated with regions of low O 2

Distribution and Activity of Ammonia-Oxidizers on the Size-Fractionated Particles in the Pearl River Estuary

Frontiers in Marine Science, 2021
To distinguish between the distribution and activity of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA) in the Pearl River estuary (PRE), we investigated the DNA- and cDNA-based β-proteobacterial and archaeal amoA genes on three size-

Diversity, Physiology, and Niche Differentiation of Ammonia-Oxidizing Archaea [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to have been a central part of the global biogeochemical nitrogen cycle since the oxygenation of Earth. The cultivation of several ammonia-oxidizing archaea (AOA) as well as the discovery that archaeal ammonia monooxygenase (

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.

Abundance and composition of ammonia‐oxidizing bacteria and ammonia‐oxidizing archaea communities of an alkaline sandy loam [PDF]

Environmental Microbiology, 2008
Summary The abundance and composition of soil ammonia‐oxidizing bacteria (AOB) and ammonia‐oxidizing archaea (AOA) communities under different long‐term (17 years) fertilization practices were investigated using real‐time polymerase chain reaction and denaturing gradient gel electrophoresis (DGGE).
