Methane cycling microorganisms drive seasonal variation of methane emission in mangrove ecosystems [PDF]

Environmental Microbiome
Coastal 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.

Immunological Localization of Coenzyme M Reductase in Anaerobic Methane-Oxidizing Archaea of ANME 1 and ANME 2 Type

Geomicrobiology Journal, 2008
The Black Sea is a large, euxinic marine basin, in which the anaerobic oxidation of methane (AOM) plays an important role in the carbon cycle. Methane-related carbonate build-ups, found on the NW' Black Sea shelf are part of an unique microbial ecosystem.

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).

Microbial Communities in and Around the Siboglinid Tubeworms from the South Yungan East Ridge Cold Seep Offshore Southwestern Taiwan at the Northern South China Sea [PDF]

Microorganisms
To date, only a few microbial community studies of cold seeps at the South China Sea (SCS) have been reported. The cold seep dominated by tubeworms was discovered at South Yungan East Ridge (SYER) offshore southwestern Taiwan by miniROV.

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

Environ Microbiol
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 ...

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.

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.

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).

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 ...

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).
