Genomic Inference of the Metabolism and Evolution of the Archaeal Phylum Aigarchaeota [PDF]
, 2018 Microbes of the phylum Aigarchaeota are widely distributed in geothermal environments, but their physiological and ecological roles are poorly understood.

Biogeography of soil Thaumarchaeota in relation to soil depth and land usage [PDF]
FEMS Microbiology Ecology, 2016 Although Thaumarchaeota are important contributors to ammonia oxidation in terrestrial habitats, distributions of ammonia oxidizers along soil depth profiles are poorly understood, especially in relation to distinct land usages. Leveraging the close proximity of forest, field and agricultural plots at the RARE: Charitable Research Reserve, we examined ...

Primer selection impacts specific population abundances but not community dynamics in a monthly time-series 16S rRNA gene amplicon analysis of coastal marine bacterioplankton. [PDF]
, 2018 Primers targeting the 16S small subunit ribosomal RNA marker gene, used to characterize bacterial and archaeal communities, have recently been re-evaluated for marine planktonic habitats.

Phylogenomics suggests oxygen availability as a driving force in Thaumarchaeota evolution [PDF]
The ISME Journal, 2019 Abstract Ammonia-oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread in marine and terrestrial habitats, playing a major role in the global nitrogen cycle. However, their evolutionary history remains unexplored, which limits our understanding of their adaptation mechanisms.

Frontiers in Microbiology, 2014 Previous studies had suggested the presence of ammonium oxidizing Thaumarchaeota as well as nitrite oxidizing Bacteria in the subsurface spring called Franz Josef Quelle (FJQ), a slightly radioactive thermal mineral spring with a temperature of 43.6 ...

Ammonia Oxidation in the Ocean can be Inhibited by Nanomolar Concentrations of Hydrogen Peroxide
Frontiers in Marine Science, 2016 Marine Thaumarchaeota were discovered over 20 years ago and although a few isolates from this group are now available for study, we do not yet understand the environmental controls on their growth and distribution.

Different behaviour of methanogenic archaea andThaumarchaeotain rice field microcosms [PDF]
FEMS Microbiology Ecology, 2013 Archaea in rice fields play an important role in carbon and nitrogen cycling. They comprise methane-producing Euryarchaeota as well as ammonia-oxidizing Thaumarchaeota, but their community structures and population dynamics have not yet been studied in the same system.

Frontiers in Microbiology, 2018 Ammonia-oxidizing archaea (AOA) within the phylum Thaumarchaeota are the only known aerobic ammonia oxidizers in geothermal environments. Although molecular data indicate the presence of phylogenetically diverse AOA from the Nitrosocaldus clade, group 1 ...
