Substitution of fiber hemp for corn did not affect soil greenhouse gas emissions from a Kentucky cropping system

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Industrial hemp's return to American agriculture has been accompanied by claims of the crop's carbon neutrality, primarily due to its commercial applications. While carbon can be sequestered within products made with hemp fiber, there is little empirical evidence quantifying greenhouse gas contributions from the crop's production.

Uncovering the Diversity and Activity of Methylotrophic Methanogens in Freshwater Wetland Soils

open access: yesmSystems, 2019
Wetland soils are one of the largest natural contributors to the emission of methane, a potent greenhouse gas. Currently, microbial contributions to methane emissions from these systems emphasize the roles of acetoclastic and hydrogenotrophic methanogens,

Key Drivers of Soil CO2, CH4, and N2O Fluxes in Conifer and Broadleaf Afforestation Systems in the Southeastern U.S.: A Machine Learning Analysis

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Soil CO2 and CH4 emissions were higher in broadleaf than conifer afforestation systems in the southeastern U.S., particularly during the growing season. Machine learning analyses identified soil temperature, moisture, and atmospheric conditions as key drivers, emphasizing that soil greenhouse gas responses critically influence the climate mitigation ...

Seasonal variation in methane ebullition in a temperate hydropower reservoir impacts annualized estimates

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Estimates of ebullitive methane (CH4) emissions from reservoirs are highly uncertain, often based on spatial and temporal upscaling from a limited number of sampling sites and periods. While some of these estimates may adjust for seasonal variation in temperature, they rarely account for drawdown and the resulting changes in site depth and the

Microbial ecosystem and methanogenesis in ruminants

open access: yesAnimal, 2010
Ruminant production is under increased public scrutiny in terms of the importance of cattle and other ruminants as major producers of the greenhouse gas methane. Methanogenesis is performed by methanogenic archaea, a specialised group of microbes present in several anaerobic environments including the rumen.

NanoFe3O4 as Solid Electron Shuttles to Accelerate Acetotrophic Methanogenesis by Methanosarcina barkeri

open access: yesFrontiers in Microbiology, 2019
Magnetite nanoparticles (nanoFe3O4) have been reported to facilitate direct interspecies electron transfer (DIET) between syntrophic bacteria and methanogens thereby improving syntrophic methanogenesis.

Concomitant Mineral Carbonation and CO2 Reduction in Short‐Term Water‐Basalts Reaction: Difference Between Basaltic Glass and Basaltic Crystals

open access: yesGlobal Challenges, Volume 10, Issue 8, August 2026.
Short‐term CO2–water reactions show that crystalline basalt undergoes more extensive carbonation than basaltic glass and is associated with detectable H2 and higher CO and CH4 concentrations. This contrast is consistent with the greater early reactivity of Fe‐ and Mg‐bearing crystalline phases, indicating that basalt mineralogy influences coupled ...

The unique biochemistry of methanogenesis

open access: yes, 2002
Methanogenic archaea have an unusual type of metabolism because they use H2 + CO2, formate, methylated C1 compounds, or acetate as energy and carbon sources for growth. The methanogens produce methane as the major end product of their metabolism in a unique energy-generating process.

Targeting methanogenesis with a nitrooxypropanol bullet [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
There is no substitute for dramatic reductions in the emissions of CO2 and other greenhouse gases to mitigate the negative consequences of climate change and, concurrently, to reduce ocean acidification. Mitigation, although technologically feasible, has been difficult to achieve for political, economic, and social reasons that may persist well into ...

Snapshot of methanogen sensitivity to temperature in Zoige wetland from Tibetan plateau

open access: yesFrontiers in Microbiology, 2015
Zoige wetland in Tibetan plateau represents a cold environment at high altitude where significant methane emission has been observed. However, it remains unknown how the production and emission of CH4 from Zoige wetland will respond to a warming climate.
