Correlating microbial community profiles with geochemical data in highly stratified sediments from the Arctic Mid-Ocean Ridge [PDF]

, 2012
Microbial communities and their associated metabolic activity in marine sediments have a profound impact on global biogeochemical cycles. Their composition and structure are attributed to geochemical and physical factors, but finding direct correlations ...

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.

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

Agronomy, 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 ...

Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry ...

Ammonia‐oxidizing archaea: important players in paddy rhizosphere soil? [PDF]

Environmental Microbiology, 2008
Summary The diversity (richness and community composition) of ammonia‐oxidizing archaea (AOA) and bacteria (AOB) in paddy soil with different nitrogen (N) fertilizer amendments for 5 weeks were investigated using quantitative real‐time polymerase chain reaction, denaturing gradient gel electrophoresis (DGGE) jand ...

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.

Archaeal dominated ammonia-oxidizing communities in Icelandic grassland soils are moderately affected by long-term N fertilization and geothermal heating

Frontiers in Microbiology, 2012
The contribution of ammonia-oxidizing bacteria and archaea (AOB and AOA, respectively) to the net oxidation of ammonia varies greatly between terrestrial environments.

Production and Excretion of Polyamines To Tolerate High Ammonia, a Case Study on Soil Ammonia-Oxidizing Archaeon “Candidatus Nitrosocosmicus agrestis”

mSystems, 2021
Ammonia tolerance is a universal characteristic among the ammonia-oxidizing bacteria (AOB); in contrast, the known species of ammonia-oxidizing archaea (AOA) have been regarded as ammonia sensitive, until the identification of the genus “Candidatus ...

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.
