Novel insights into the Thaumarchaeota in the deepest oceans: their metabolism and potential adaptation mechanisms [PDF]

Microbiome, 2020
Background Marine Group I (MGI) Thaumarchaeota, which play key roles in the global biogeochemical cycling of nitrogen and carbon (ammonia oxidizers), thrive in the aphotic deep sea with massive populations.

Environmental Variables Shaping the Ecological Niche of Thaumarchaeota in Soil: Direct and Indirect Causal Effects.

PLoS ONE, 2015
To find environmental variables (EVs) shaping the ecological niche of the archaeal phylum Thaumarchaeota in terrestrial environments, we determined the abundance of Thaumarchaeota in various soil samples using real-time PCR targeting thaumarchaeotal 16S ...

Nitrification and growth of autotrophic nitrifying bacteria and Thaumarchaeota in the coastal North Sea [PDF]

Biogeosciences, 2013
Nitrification and the associated growth of autotrophic nitrifiers, as well as the contributions of bacteria and Thaumarchaeota to total autotrophic C-fixation by nitrifiers were investigated in the Dutch coastal North Sea from October 2007 to March 2008.

The large-scale distribution of ammonia oxidizers in paddy soils is driven by soil pH, geographic distance and climatic factors

Frontiers in Microbiology, 2015
Paddy soils distribute widely from temperate to tropical regions, and are characterized by intensive nitrogen fertilization practices in China. Mounting evidence has confirmed the functional importance of ammonia-oxidizing archaea (AOA) and bacteria (AOB)

The Role of Heterotrophic Bacteria and Archaea in the Transformation of Lignin in the Open Ocean

Frontiers in Marine Science, 2019
The pelagic ocean receives terrigenous inputs of a range of organic compounds; however, the role that this terrigenous material plays in the ocean carbon cycle and biological pump is not entirely understood, and questions remain as to how oceanic cycles ...

Seasonality and depth distribution of the abundance and activity of ammonia oxidizing microorganisms in marine coastal sediments (North Sea)

Frontiers in Microbiology, 2014
Microbial processes such as nitrification and anaerobic ammonium oxidation (anammox) are important for nitrogen cycling in marine sediments. Seasonal variations of archaeal and bacterial ammonia oxidizers (AOA and AOB) and anammox bacteria, as well as ...

Analysis of composition and structure of coastal to mesopelagic bacterioplankton communities in the northern Gulf of Mexico

Frontiers in Microbiology, 2013
16S rRNA gene amplicons were pyrosequenced to assess bacterioplankton community composition, diversity and phylogenetic community structure for 17 stations in the northern Gulf of Mexico (nGoM) sampled in March 2010.

Characterization of the Exometabolome of Nitrosopumilus maritimus SCM1 by Liquid Chromatography–Ion Mobility Mass Spectrometry

Frontiers in Microbiology, 2021
Marine Thaumarchaeota (formerly known as the marine group I archaea) have received much research interest in recent years since these chemolithoautotrophic organisms are abundant in the subsurface ocean and oxidize ammonium to nitrite, which makes them a
