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.

Composition and Metabolic Potential of Fe(III)-Reducing Enrichment Cultures of Methanotrophic ANME-2a Archaea and Associated Bacteria

Microorganisms, 2023
The key microbial group involved in anaerobic methane oxidation is anaerobic methanotrophic archaea (ANME). From a terrestrial mud volcano, we enriched a microbial community containing ANME-2a, using methane as an electron donor, Fe(III) oxide ...

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 ...

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.

Anaerobic methanotrophic archaea of the ANME-2d clade feature lipid composition that differs from other ANME archaea [PDF]

FEMS Microbiology Ecology, 2019
ABSTRACT The anaerobic oxidation of methane (AOM) is a microbial process present in marine and freshwater environments. AOM is important for reducing the emission of the second most important greenhouse gas methane. In marine environments anaerobic methanotrophic archaea (ANME) are involved in sulfate-reducing AOM.

Carbon monoxide oxidation expands the known metabolic capacity in anaerobic methanotrophic consortia [PDF]

Nature Communications
Consortia of anaerobic methane-oxidizing archaea (ANME-2) and sulphate-reducing bacteria (SRB) represent globally relevant syntrophic associations capable of growing with minimal amounts of free energy and can persist when methane becomes limiting ...

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 ...

Drivers of methane-cycling archaeal abundances, community structure, and catabolic pathways in continental margin sediments [PDF]

Frontiers in Microbiology
Marine sediments contain Earth’s largest reservoir of methane, with most of this methane being produced and consumed in situ by methane-cycling archaea. While numerous studies have investigated communities of methane-cycling archaea in hydrocarbon seeps ...
