Marine Cold Seep ANME ‐2/ SRB Consortia Produce Their Lipid Biomass From Inorganic Carbon [PDF]

Environmental Microbiology
Lipid‐stable isotope probing (SIP) experiments in Astoria Canyon sediments revealed that both ANME‐2 and SRB primarily assimilate dissolved inorganic carbon (DIC or HCO3‐), not methane, into biomass. SRB‐specific lipids showed eightfold higher DI13C‐assimilation than ANME lipids, suggesting SRB directly assimilate DIC, while ANME assimilate an ...

Structure and Spatial Heterogeneity of Chemosynthesis-Based Deep-Sea Archaeal and Bacterial Communities in Western South Atlantic. [PDF]

Ecol Evol
We report an extensive investigation of prokaryotic communities from a methane cold‐seep area in the Western South Atlantic Ocean (Southern Brazil) employing a broad sample set, including three distinct geographic areas (A, C and E) across a depth gradient (up to 18 m below the seafloor) related to the sulfate–methane transition zone (SMTZ).

Beyond Methane Oxidation: The Protein Landscape of ANME-2a Reveals an Integrated System for Diazotrophy and Membrane Fortification. [PDF]

Environ Microbiol Rep
A protein interaction network of ANME‐2a uncovers a modular blueprint where core methane oxidation is energetically coupled to nitrogen fixation and membrane lipid biosynthesis. This integrated system explains the archaeon's metabolic autonomy and resilience in its extreme deep‐sea niche.

Genomic Insights into Niche Partitioning across Sediment Depth among Anaerobic Methane-Oxidizing Archaea in Global Methane Seeps

mSystems, 2023
Marine sediments are important methane reservoirs. Methane efflux from the seabed is significantly restricted by anaerobic methanotrophic (ANME) archaea through a process known as anaerobic oxidation of methane (AOM).

Comparative genomics reveals electron transfer and syntrophic mechanisms differentiating methanotrophic and methanogenic archaea.

PLoS Biology, 2022
The anaerobic oxidation of methane coupled to sulfate reduction is a microbially mediated process requiring a syntrophic partnership between anaerobic methanotrophic (ANME) archaea and sulfate-reducing bacteria (SRB).

The presence of benzene ring activating CoA ligases for aromatics degradation in the ANaerobic MEthanotrophic (ANME) archaea

Microbiology Spectrum, 2023
Petroleum-source and black carbon-source aromatic compounds are present in the cold seep environments, where ANaerobic MEthanotrophic (ANME) archaea as the dominant microbial community mediates the anaerobic oxidation of methane to produce inorganic and ...

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).

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.

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

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
