Methanogens and Methanogenesis in Hypersaline Environments [PDF]

, 2018
Methanogenesis is controlled by redox potential and permanency of anaerobic conditions; and in hypersaline environments, the high concentration of terminal electron acceptors, particularly sulfate, is an important controlling factor.

Effect of Dissimilatory Iron Reduction on the Reduction of CH4 Production in Landfill Conditions

Journal of Chemistry, 2019
A high solid anaerobic incubation system was used to study the effect of dissimilatory iron reduction on the inhibition of methanogenesis in a landfill. Different iron sources including FeC6H5O7, Fe2(SO4)3, Fe2O3, and Fe0 were studied. The different iron

Cation responses to global changes alter ecological processes in ombrotrophic systems

Journal of Ecology, Volume 114, Issue 7, July 2026.
Ombrotrophic bogs, which store large amounts of carbon as peat, receive all their mineral nutrition through deposition, making them particularly sensitive to cation‐displacing global changes. Here, we review the limited yet compelling evidence that cation availability is a key determinant of ecological processes across scales of ecological organisation

Soluble microbial products (SMP) of acetotrophic methanogenesis [PDF]

, 1998
Experiments on acetotrophic methanogenesis were conducted at 37°C in a 3.5 l chemostat reactor and ten 120 ml batch reactors. The degradation process produced substantial quantities of soluble microbial products (SMP). Converting 1 mg of acetate produced

Extracellular electron transfer based methylotrophic methanogenesis in paddy soil and the prevalent Methanomassiliicoccus

Communications Earth & Environment
The biogenic methane contributes obviously to global warming, and direct interspecies electron transfer (DIET) driven CO2 reductive methanogenesis is one of the important methanogenic pathways.

Methanogenesis from methanol in Methanosarcina barkeri studied using membrane inlet mass spectrometry [PDF]

, 1986
A mass spectrometer with membrane inlet was used to study methanol metabolism by Methanosarcina barkeri strain MS. The addition of methanol to methanol grown culture samples in the mass spectrometer vessel stimulated methanogenesis and hydrogen ...

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

Boreas, Volume 55, Issue 3, Page 790-807, July 2026.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

Methanogenesis in oxygenated soils is a substantial fraction of wetland methane emissions [PDF]

, 2017
The current paradigm, widely incorporated in soil biogeochemical models, is that microbial methanogenesis can only occur in anoxic habitats. In contrast, here we show clear geochemical and biological evidence for methane production in well-oxygenated ...

Energetic and genomic potential for hydrogenotrophic, formatotrophic, and acetoclastic methanogenesis in surface-expressed serpentinized fluids of the Samail Ophiolite

Frontiers in Microbiology
Serpentinization, the reaction of water with ultramafic rock, produces reduced, hyperalkaline, and H2-rich fluids that support a variety of hydrogenotrophic microbial metabolisms.

A Drier Year Markedly Enhances Methane, but Not Carbon Dioxide, Emissions in a Mediterranean Reservoir

Global Change Biology, Volume 32, Issue 7, July 2026.
We monitored greenhouse gas emissions from a Mediterranean reservoir over 2 years that differed markedly in water availability. Methane emissions were much higher during the drier year, largely because lower water levels and warmer bottom waters favored methane production and release, while carbon dioxide emissions were less affected.
