Secondary succession of ammonia oxidizing archaea in Everglades agricultural soil

open access: yes, 2023
This study examined the community compositional change of ammonia-oxidizing archaea during 95-day microcosm incubation following a simulated population-reducing disturbance by killing 95% of the native microbial ...

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

open access: yesPLoS 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 ...

open access: yesMajor Reference Works, Page 1-35.

Bergey's Manual of Systematics of Archaea and Bacteria (BMSAB) is a reference work aimed at undergraduates, graduate students, researchers, professors and experienced professionals at all levels. About a hundred new genera and 600+ new species have been described per year for each of the last 5 years.

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

open access: yesApplied 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 (

Land-use systems affect Archaeal community structure and functional diversity in western Amazon soils

open access: yesRevista Brasileira de Ciência do Solo, 2011
The study of the ecology of soil microbial communities at relevant spatial scales is primordial in the wide Amazon region due to the current land use changes.

Ammonia‐oxidizing archaea and nitrite‐oxidizing nitrospiras in the biofilter of a shrimp recirculating aquaculture system [PDF]

open access: yes, 2013
This study analysed the nitrifier community in the biofilter of a zero discharge, recirculating aquaculture system ( RAS ) for the production of marine shrimp in a low density (low ammonium production) system.

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

open access: yesFrontiers 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-

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

open access: yesEnvironmental 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

Enhanced Endophytic Colonization of Flavobacterium Promotes Plant Resistance to Fusarium Wilt

open access: yesAdvanced Science, EarlyView.
A natural microbial consortium employing a cross‐feeding strategy forms a stratified biofilm that promotes endophytic colonization of auxotrophic Flavobacterium. This enhanced colonization activates plant systemic resistance, effectively suppressing Fusarium wilt.

Distribution and Abundance of Archaea in South China Sea SpongeHoloxeasp. and the Presence of Ammonia-Oxidizing Archaea in Sponge Cells [PDF]

open access: yes, 2011
Compared with bacterial symbionts, little is known about archaea in sponges especially about their spatial distribution and abundance. Understanding the distribution and abundance of ammonia-oxidizing archaea will help greatly in elucidating the ...
