The Mechanism of Sodium Sulfate Coupled with Anaerobic Methane Oxidation Mitigating Methane Production in Beef Cattle

Microorganisms
The aim of this experiment is to explore the effect of sodium sulfate (Na2SO4) on methane reduction in the rumen, and its impact on anaerobic methane-oxidizing archaea (ANME).

Methane seep in shallow-water permeable sediment harbors high diversity of anaerobic methanotrophic communities, Elba, Italy

Frontiers in Microbiology, 2016
The anaerobic oxidation of methane (AOM) is a key biogeochemical process regulating methane emission from marine sediments into the hydrosphere. AOM is largely mediated by consortia of anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria

Microbial communities of deep-sea methane seeps at Hikurangi continental margin (New Zealand). [PDF]

PLoS ONE, 2013
The methane-emitting cold seeps of Hikurangi margin (New Zealand) are among the few deep-sea chemosynthetic ecosystems of the Southern Hemisphere known to date. Here we compared the biogeochemistry and microbial communities of a variety of Hikurangi cold

Novel Extended Tetraether Lipids Found in a High‐CO2 Geyser

Environmental Microbiology, Volume 28, Issue 3, March 2026.
Characterisation of the archaeal lipidome of the CO2‐rich subsurface aquifer of the Geyser Andernach reveals novel extended tetraether lipids analogous to extended archaeols, likely produced by Candidatus Altiarchaeum, and potentially functioning as a membrane adaptation strategy to nutrient‐deprived conditions.

Biogeochemical evidence of anaerobic methane oxidation on active submarine mud volcanoes on the continental slope of the Canadian Beaufort Sea [PDF]

Biogeosciences, 2018
In this study, we report lipid biomarker patterns and phylogenetic identities of key microbial communities mediating anaerobic oxidation of methane (AOM) in active mud volcanoes (MVs) on the continental slope of the Canadian Beaufort Sea.

Hard Rock Buffet: Chemosynthetic Carbon Use and Environmental Trophic Structuring of Carbonate‐Associated Macrofauna at Southern California Methane Seeps

Marine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Diverse invertebrate communities inhabiting carbonate rocks at methane seeps may rely on a mix of local chemosynthetic production and sinking photosynthetic organic matter, with relative importance shaped by environmental conditions. We investigate the contribution of chemosynthetic carbon to macrofaunal diets at six Southern California ...

A metagenomic study of methanotrophic microorganisms in Coal Oil Point seep sediments

BMC Microbiology, 2011
Background Methane oxidizing prokaryotes in marine sediments are believed to function as a methane filter reducing the oceanic contribution to the global methane emission.

Stratified community responses to methane and sulfate supplies in mud volcano deposits: insights from an in vitro experiment. [PDF]

PLoS ONE, 2014
Numerous studies on marine prokaryotic communities have postulated that a process of anaerobic oxidation of methane (AOM) coupled with sulfate reduction (SR) is the main methane sink in the world's oceans. AOM has also been reported in the deep biosphere.

Clumped isotopes as fingerprints of microbial methane production pathways in marine sediments

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Microbial methanogenesis in marine sediments produces significant amounts of methane from various substrates; however, identifying the active pathways in situ remains challenging. While the bulk and clumped isotopic signatures of methane from different pathways have been studied in pure cultures, these are difficult to compare with complex ...

Comparative Study of Guaymas Basin Microbiomes: Cold Seeps vs. Hydrothermal Vents Sediments

Frontiers in Marine Science, 2017
In the Guaymas Basin, the presence at a few tens of kilometers of cold seeps and hydrothermal vents coupled with comparable sedimentary settings and depths offer a unique opportunity to assess and compare the microbial community composition of these deep-
