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 ...

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.

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.

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

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

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 ...

Microbially driven methane and sulfur cycling processes and coupling mechanisms in mangrove sediments [PDF]
Environmental MicrobiomeBackground Methane (CH4) as a powerful greenhouse gas is the second largest contributor to global climate warming. Mangrove sediments are an important natural source of biogenic CH4 with rich organic carbon (C) and diverse sulfur (S) compounds, ideally ...

Methane cycling microorganisms drive seasonal variation of methane emission in mangrove ecosystems [PDF]
Environmental MicrobiomeCoastal mangroves are one of the significant hotspots of natural methane (CH4) emissions, yet the seasonal dynamics of these emissions and the underlying microbial drivers remain poorly understood.

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

Diversity of Anaerobic Methane Oxidizers in the Cold Seep Sediments of the Okinawa Trough
Frontiers in Microbiology, 2022 Active cold seeps in the Okinawa Trough (OT) have been widely identified, but the sediment microbial communities associated with these sites are still poorly understood.
