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.

Millimetre-Scale Stratification of Microbial Communities in Hydrothermal Sediments. [PDF]

Environ Microbiol
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...

Lipidomic diversity and proxy implications of archaea from cold seep sediments of the South China Sea

Frontiers in Microbiology, 2023
Cold seeps on the continental margins are characterized by intense microbial activities that consume a large portion of methane by anaerobic methanotrophic archaea (ANME) through anaerobic oxidation of methane (AOM).

Horizontal and vertical heterogeneity of sediment microbial community in Site F cold seep, the South China Sea

Frontiers in Marine Science, 2022
Site F is the most vigorous cold seep known on the continental slope of the northern South China Sea. Up to now, the microbial community structures in sediments of Site F based on the high-throughput sequencing of the 16S rRNA genes have been studied ...

ANME ‐1 archaea may drive methane accumulation and removal in estuarine sediments [PDF]

Environmental Microbiology Reports, 2020
Summary ANME‐1 archaea subsist on the very low energy of anaerobic oxidation of methane (AOM). Most marine sediments shift from net AOM in the sulfate methane transition zone (SMTZ) to methanogenesis in the methane zone (MZ) below it. In White Oak River estuarine sediments, ANME‐1 comprised 99.5% of 16S rRNA genes

Enhancing methane oxidation in a bioelectrochemical membrane reactor using a soluble electron mediator

Biotechnology for Biofuels, 2020
Background Bioelectrochemical methane oxidation catalysed by anaerobic methanotrophic archaea (ANME) is constrained by limited methane bioavailability as well as by slow kinetics of extracellular electron transfer (EET) of ANME.

Zonation of the active methane-cycling community in deep subsurface sediments of the Peru trench

Frontiers in Microbiology, 2023
The production and anaerobic oxidation of methane (AOM) by microorganisms is widespread in organic-rich deep subseafloor sediments. Yet, the organisms that carry out these processes remain largely unknown.

Physiological potential and evolutionary trajectories of syntrophic sulfate-reducing bacterial partners of anaerobic methanotrophic archaea.

PLoS Biology, 2023
Sulfate-coupled anaerobic oxidation of methane (AOM) is performed by multicellular consortia of anaerobic methanotrophic archaea (ANME) in obligate syntrophic partnership with sulfate-reducing bacteria (SRB).

Integrated metagenomic and metaproteomic analyses of an ANME‐1‐dominated community in marine cold seep sediments [PDF]

Environmental Microbiology, 2012
Summary Sulfate‐reducing methanotrophy by anaerobic methanotrophic archaea (ANME) and sulfate‐reducing bacteria (SRB) is a major biological sink of methane in anoxic methane‐enriched marine sediments. The physiology of a microbial community dominated by free‐living ANME‐1 at 14–16 cm below the seafloor in the G11 ...

A PCR-Based Survey of Methane-Cycling Archaea in Methane-Soaked Subsurface Sediments of Guaymas Basin, Gulf of California

Microorganisms, 2023
The Guaymas Basin in the Gulf of California is characterized by active seafloor spreading, the rapid deposition of organic-rich sediments, steep geothermal gradients, and abundant methane of mixed thermogenic and microbial origin.
