Lateral Gene Transfer Drives Metabolic Flexibility in the Anaerobic Methane-Oxidizing Archaeal Family Methanoperedenaceae

mBio, 2020
Anaerobic oxidation of methane (AOM) is an important biological process responsible for controlling the flux of methane into the atmosphere. Members of the archaeal family Methanoperedenaceae (formerly ANME-2d) have been demonstrated to couple AOM to the

Subgroup characteristics of marine methane-oxidizing ANME-2 archaea and their syntrophic partners revealed by integrated multimodal analytical microscopy [PDF]

, 2018
Phylogenetically diverse environmental ANME archaea and sulfate-reducing bacteria cooperatively catalyze the anaerobic oxidation of methane oxidation (AOM) in multicelled consortia within methane seep environments.

The onset of synchronization in large networks of coupled oscillators

, 2005
We study the transition from incoherence to coherence in large networks of coupled phase oscillators. We present various approximations that describe the behavior of an appropriately defined order parameter past the transition, and generalize recent ...

Diverse Cooccurring Metabolisms Support Sulfur and Methane Cycling in Wetland Surficial Sediments

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract The Prairie Pothole Region (PPR) of North America contains millions of small depressional wetlands with some of the highest methane (CH4) fluxes ever reported in terrestrial ecosystems. In saturated soils, two conventional paradigms are (a) methanogenesis is the final step in the redox ladder, occurring only after more thermodynamically ...

Activity and interactions of methane seep microorganisms assessed by parallel transcription and FISH-NanoSIMS analyses [PDF]

, 2015
To characterize the activity and interactions of methanotrophic archaea (ANME) and Deltaproteobacteria at a methane-seeping mud volcano, we used two complimentary measures of microbial activity: a community-level analysis of the transcription of four ...

Methane‐Driven Arsenic Biogeochemical Cycling in Deep‐Sea Cold Seeps: Implications for Oceanic Arsenic Geochemistry

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Arsenic accumulation in seafloor cold seeps is poorly understood. Here, we investigate the interplay between arsenic and methane biogeochemical cycles at the Haima cold seep, South China Sea. Geochemical analyses showed elevated arsenic levels in seep sediments, primarily as sulfide‐bound forms, with strong correlations between dissolved ...

In Situ Metabolic Rates of Alkane‐Degrading Sulphate‐Reducing Bacteria in Hydrocarbon Seep Sediments Revealed by Combining CARD‐FISH, NanoSIMS, and Mathematical Modelling

Environmental Microbiology, Volume 27, Issue 8, August 2025.
Sulphate‐reducing bacteria affiliated with clades SCA1, SCA2, and LCA2 were investigated using stable‐isotope incubations and in situ analysis at several hydrocarbon seep sites. Extrapolated rates of sulphate reduction and alkane degradation suggest that these clades play an important role at hydrocarbon seeps, contributing substantially to sulphur and

An oligotrophic deep-subsurface community dependent on syntrophy is dominated by sulfur-driven autotrophic denitrifiers [PDF]

, 2016
Subsurface lithoautotrophic microbial ecosystems (SLiMEs) under oligotrophic conditions are typically supported by H₂. Methanogens and sulfate reducers, and the respective energy processes, are thought to be the dominant players and have been the ...

Community Structure and Function of Aerobic Methanotrophs in Urban River Sediments: A Case Study of the Jialing River

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
Urban river sediments collected from the downstream sites of Jialing River possess the highest aerobic methane oxidation potential. The potential is affected by river carbon and nitrogen contents. Type I methanotrophs contribute to the activity. ABSTRACT Rivers are hotspots of global methane emission and oxidation, yet research on aerobic methanotrophy
