Evolutionary diversification of methanotrophic ANME-1 archaea and their expansive virome [PDF]

Nature Microbiology, 2023
ANME-1 archaea are important because of their ability to metabolize methane through anaerobic oxidation. Here the authors use metagenomics on hydrothermal samples from the Gulf of California to characterize a family of ANME-1 and its virome.

Physiological versatility of ANME-1 and Bathyarchaeotoa-8 archaea evidenced by inverse stable isotope labeling [PDF]

Microbiome
Background The trophic strategy is one key principle to categorize microbial lifestyles, by broadly classifying microorganisms based on the combination of their preferred carbon sources, electron sources, and electron sinks.

Growth and activity of ANME clades with different sulfate and sulfide concentrations in presence of methane [PDF]

Frontiers in Microbiology, 2015
Extensive geochemical data showed that significant methane oxidation activity exists in marine sediments. The organisms responsible for this activity are anaerobic methane-oxidizing archaea (ANME) that occur in consortia with sulfate-reducing bacteria. A

Deep-branching ANME-1c archaea grow at the upper temperature limit of anaerobic oxidation of methane

Frontiers in Microbiology, 2022
In seafloor sediments, the anaerobic oxidation of methane (AOM) consumes most of the methane formed in anoxic layers, preventing this greenhouse gas from reaching the water column and finally the atmosphere.

Electron Acceptor Availability Shapes Anaerobically Methane Oxidizing Archaea (ANME) Communities in South Georgia Sediments

Frontiers in Microbiology, 2021
Anaerobic methane oxidizing archaea (ANME) mediate anaerobic oxidation of methane (AOM) in marine sediments and are therefore important for controlling atmospheric methane concentrations in the water column and ultimately the atmosphere.

Atomic resolution structures of the methane-activating enzyme in anaerobic methanotrophy reveal extensive post-translational modifications [PDF]

Nature Communications
Anaerobic methanotrophic archaea (ANME) are crucial to planetary carbon cycling. They oxidise methane in anoxic niches by transferring electrons to nitrate, metal oxides, or sulfate-reducing bacteria.

Evaluation and optimization of PCR primers for selective and quantitative detection of marine ANME subclusters involved in sulfate-dependent anaerobic methane oxidation [PDF]

Applied Microbiology and Biotechnology, 2017
Since the discovery that anaerobic methanotrophic archaea (ANME) are involved in the anaerobic oxidation of methane coupled to sulfate reduction in marine sediments, different primers and probes specifically targeting the 16S rRNA gene of these archaea ...

Miniaturized biosignature analysis reveals implications for the formation of cold seep carbonates at Hydrate Ridge (off Oregon, USA) [PDF]

Biogeosciences, 2008
Methane-related carbonates from Hydrate Ridge typically show several macroscopically distinguishable mineral phases, namely whitish aragonite, lucent aragonite, and gray micrite.

Stratified community responses to methane and sulfate supplies in mud volcano deposits: insights from an in vitro experiment. [PDF]

PLoS ONE, 2014
Numerous studies on marine prokaryotic communities have postulated that a process of anaerobic oxidation of methane (AOM) coupled with sulfate reduction (SR) is the main methane sink in the world's oceans. AOM has also been reported in the deep biosphere.

Fine-Scale Community Structure Analysis of ANME in Nyegga Sediments with High and Low Methane Flux

Frontiers in Microbiology, 2012
To obtain knowledge on how regional variations in methane seepage rates influence the stratification, abundance and diversity of anaerobic methanotrophs (ANME) we analyzed the vertical microbial stratification in a gravity core from a methane micro ...
