Archaea predominate among ammonia-oxidizing prokaryotes in soils
TLDR
It is shown that archaeal ammonia oxidizers are more abundant in soils than their well-known bacterial counterparts, and crenarchaeota may be the most abundant ammonia-oxidizing organisms in soil ecosystems on Earth. Expand
Nitrososphaera viennensis, an ammonia oxidizing archaeon from soil
TLDR
The cultivation and isolation of an AOA from soil is described, showing it grows on ammonia or urea as an energy source and is capable of using higher ammonia concentrations than the marine isolate, Nitrosopumilus maritimus. Expand
Simultaneous Assessment of Soil Microbial Community Structure and Function through Analysis of the Meta-Transcriptome
TLDR
An RNA-centered meta-transcriptomic approach is applied to simultaneously obtain information on both structure and function of a soil community by efficiently linking community structure andfunction in a single experiment while avoiding biases inherent in other methods. Expand
A communal catalogue reveals Earth’s multiscale microbial diversity
TLDR
A meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project is presented, creating both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth’s microbial diversity. Expand
Nitrification in terrestrial hot springs of Iceland and Kamchatka.
TLDR
Evidence is provided for an active role of archaea in nitrification of hot springs in a wide range of pH values and at a high temperature, and addition of ammonium to the hot spring samples before incubation yielded a more than twofold higher potential nitrification rate, indicating that the process was limited by ammonia supply. Expand
Methylotrophic methanogenic Thermoplasmata implicated in reduced methane emissions from bovine rumen.
TLDR
It is shown that the poorly characterised Thermoplasmata archaea in bovine rumen are methylotrophic methanogens and that they are reduced upon dietary supplementation with rapeseed oil in lactating cows. Expand
Responses of the terrestrial ammonia-oxidizing archaeon Ca. Nitrososphaera viennensis and the ammonia-oxidizing bacterium Nitrosospira multiformis to nitrification inhibitors.
TLDR
The results reflect the fundamental metabolic and cellular differences of AOA and AOB and will be useful for future applications of inhibitors aimed at distinguishing activities of aOA and aOB in soil environments. Expand
Organic carbon transformations in high-Arctic peat soils: key functions and microorganisms
TLDR
It is concluded that these Arctic peat soils will turn into CO2 sources owing to increased active layer depth and prolonged growing season, however, the extent of future CH4 emissions will critically depend on the response of the methanotrophic bacteria. Expand
Dissimilatory Oxidation and Reduction of Elemental Sulfur in Thermophilic Archaea
TLDR
The current knowledge on the composition and properties of the aerobic and anaerobic pathways of dissimilatory elemental sulfur metabolism in thermophilic archaea is summarized in this contribution. Expand
Coupling of the pathway of sulphur oxidation to dioxygen reduction: characterization of a novel membrane‐bound thiosulphate:quinone oxidoreductase
TLDR
Oxygen consumption was measured in membrane fractions upon thiosulphate addition, thus linking thiosULphate oxidation to dioxygen reduction, in what constitutes a novel activity among Archaea. Expand
