Cryptic Carbon Cycle at Methane‐Seeps of the South China Sea: Evidence From Porewaters

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Anaerobic oxidation of methane (AOM) governs methane consumption at seeps, yet δ13C‐CH4 values in the sulfate‐methane transitions are commonly lower than predicted from preferential 12C utilization by methanotrophic archaea, suggesting the influence of a different methane source. To address this isotope discrepancy, we used high‐resolution ion

Habitat Diversity Sustains Ecosystem Functioning in Plateau Arid‐Region Wetlands

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Habitat diversity underpins both biodiversity and functional biogeochemical processes in plateau arid‐region wetlands, thereby stabilizing ecosystem functioning. These functionally complementary habitats collectively drive critical ecosystem processes.

Spatial Heterogeneity in Methane Biogeochemistry and Prokaryotic Community Structure in Sub‐Arctic Waterbodies in Northern Canada

Environmental Microbiology, Volume 27, Issue 12, December 2025.
Prokaryotic communities and methane dynamics differed markedly across 16 sub‐Arctic waterbodies. Maximum depth and permafrost thaw emerged as key drivers, with non‐stratified thaw‐affected sites hosting distinct communities and elevated methane fluxes, highlighting their potential role as emerging hotspots of methane emissions.

Isolation and characterization of a thermophilic, obligately anaerobic and heterotrophic marine Chloroflexi bacterium from a Chloroflexi dominated microbial community associated with a Japanese shallow hydrothermal system, and proposal for Thermomarinilinea lacunofontalis gen. nov., sp. nov. [PDF]

, 2013
A novel marine thermophilic and heterotrophic Anaerolineae bacterium in the phylum Chloroflexi, strain SW7T, was isolated from an in situ colonization system deployed in the main hydrothermal vent of the Taketomi submarine hot spring field located on the

Nitrogen and carbon flows in a microbial mat involving anaerobic oxidation of methane in northwestern Black Sea: perspectives from nitrogen and carbon isotopic composition of coenzyme F430 and its biosynthetic pathway

Progress in Earth and Planetary Science
Coenzyme F430, a nickel-containing tetrapyrrole, serves as a cofactor for methyl-coenzyme M reductase (MCR), which catalyzes both the final step of methanogenesis and the initial step of anaerobic oxidation of methane (AOM).

Niche Differentiation of Sulfate- and Iron-Dependent Anaerobic Methane Oxidation and Methylotrophic Methanogenesis in Deep Sea Methane Seeps

Frontiers in Microbiology, 2020
Methane seeps are widespread seafloor ecosystems shaped by complex physicochemical-biological interactions over geological timescales, and seep microbiomes play a vital role in global biogeochemical cycling of key elements on Earth.

The Apparent Involvement of ANMEs in Mineral Dependent Methane Oxidation, as an Analog for Possible Martian Methanotrophy [PDF]

, 2011
On Earth, marine anaerobic methane oxidation (AOM) can be driven by the microbial reduction of sulfate, iron, and manganese. Here, we have further characterized marine sediment incubations to determine if the mineral dependent methane oxidation ...

Biogeochemical Activity of Methane-Related Microbial Communities in Bottom Sediments of Cold Seeps of the Laptev Sea

Microorganisms, 2023
Bottom sediments at methane discharge sites of the Laptev Sea shelf were investigated. The rates of microbial methanogenesis and methane oxidation were measured, and the communities responsible for these processes were analyzed.
