Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1632-1642, August 2026.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...

Quantifying temporal dynamics of greenhouse gas emissions in lake mesocosms: Deployment of a low‐cost measurement system

Limnology and Oceanography: Methods, Volume 24, Issue 8, August 2026.
Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

Climate Constraints on the Methane‒Carbon Efficiency of Global Wetlands: Spatiotemporal Drivers and Future Projections

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Wetlands play an important role in the growth rate of atmospheric methane (CH4) concentrations, with gross primary productivity (GPP) serving as a key proxy for predicting CH4 fluxes, yet the efficiency with which photosynthetic carbon is associated with CH4 fluxes remains poorly quantified at the global scale. Here, we integrated multiple GPP

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

Carbonate‐Associated Sulfate Does Not Record Superheavy δ34S in Deep Scandinavian Bedrock Fractures: Implications for Pyrite Formation in the Deep Biosphere

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract In deep bedrock fractures of the Fennoscandian shield, pyrite with “superheavy” δ34S values of up to 147‰ exists together with calcite. The extreme variability and 34S‐enrichment in pyrite indicate that microbial sulfate reduction (MSR) evolved to almost complete sulfate exhaustion in closed‐system microenvironments.

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.

Elevated Spring Methane Emissions in a Sub‐Arctic Peatland Fen

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract The Arctic boreal region is rapidly shifting in response to global climate change, including rapid warming and permafrost thaw. Year‐round monitoring of carbon fluxes in these regions is crucial to understanding seasonal and annual carbon budgets, including methane (CH4), a potent greenhouse gas with 80 times the warming potential of carbon ...

Putative Mechanisms for Initial Reaction of Anaerobic Benzene Degradation Presumably Involving a Flavoprotein

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Anaerobic biodegradation of benzene by sulphate‐reducing strain BzS1 was studied by combining genomics, differential proteomics and targeted metabolite analyses. Strain BzS1 has an exceptionally streamlined metabolism. A highly abundant heterotrimeric flavoprotein may add benzene to either enolpyruvate or glutaconyl‐CoA followed by channelling into the

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.

Hydrological Threshold for Optimizing Wetland Climate Mitigation

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Wetland carbon cycling reflects an intrinsic balance between CO2 sequestration and anaerobic methane production, though hydrological drivers remain insufficiently quantified. Here, we synthesize eddy covariance data from 43 natural wetlands spanning diverse climates and hydrological regimes to quantify greenhouse gas (GHG) responses to water ...
