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

open access: yes, 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.

Metabolic capabilities of microorganisms involved in and associated with the anaerobic oxidation of methane

open access: yesFrontiers in Microbiology, 2016
In marine sediments the anaerobic oxidation of methane with sulfate as electron acceptor (AOM) is responsible for the removal of a major part of the greenhouse gas methane.

Genome‐Resolved Approach of Guerrero Negro Hypersaline Microbial Mats Reveals the Metabolic Potential of Key Players in a Stratified Community

open access: yesEnvironmental Microbiology, Volume 27, Issue 11, November 2025.
The first metagenome‐assembled genomes (MAGs) from Guerrero Negro hypersaline microbial mats were recovered from natural and incubated samples. These MAGs include dominant and rare taxa, whose metabolic potential provides clues to metabolic versatility in the cycling of three elements (carbon, sulfur, and nitrogen) at the genome and community levels ...

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

open access: yesmBio, 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

Archaea catalyze iron-dependent anaerobic oxidation of methane [PDF]

open access: yes, 2016
Anaerobic oxidation of methane (AOM) is crucial for controlling the emission of this potent greenhouse gas to the atmosphere. Nitrite-, nitrate-, and sulfate-dependent methane oxidation is well-documented, but AOM coupled to the reduction of oxidized ...

Geriatric Nutritional Risk Index and In‐Hospital Mortality and Costs in Older Inpatients With and Without Cancer: A Retrospective Observational Study

open access: yesJournal of Clinical Nursing, Volume 34, Issue 11, Page 4630-4641, November 2025.
ABSTRACT Aims To explore the association of the Geriatric Nutritional Risk Index (GNRI) with in‐hospital mortality and costs in older inpatients and to compare these associations between cancer and non‐cancer patients to inform clinical practice. Design Retrospective observational study.

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

open access: yes, 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 ...

Chemosynthetic Organic Matter Reveals a Protracted Episode of Past Methane Seepage Activities at a Newly Discovered Cold Seep Site (Mannar Basin) Off the East Coast of India

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Here, we present organic geochemical evidence of past methane‐seepage events in a sediment core retrieved from a recently discovered methane cold‐seep site off Mannar Basin, east coast of India. The significant negative C‐isotope excursion of organic matter (δ13CTOC) in the seep core compared to a reference non‐seep core suggests a substantial

Chemotrophic Microbial Mats and Their Potential for Preservation in the Rock Record [PDF]

open access: yes, 2009
Putative microbialites are commonly regarded to have formed in association with photosynthetic microorganisms, such as cyanobacteria. However, many modern microbial mat ecosystems are dominated by chemotrophic bacteria and archaea.
