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

open access: yesJournal 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 ...

Contrasting temporal drivers of methane flux across land uses in freshwater wetlands

open access: yesLimnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Wetlands are collectively the largest natural source of methane (CH4), which complicates the climate mitigation potential of wetland restoration. Land‐use change alters wetland soils, vegetation, and hydrology, but the impact of this disturbance legacy on CH4 fluxes from restored wetlands is uncertain.

Elevated Spring Methane Emissions in a Sub‐Arctic Peatland Fen

open access: yesJournal 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 ...

Investigation and manipulation of metabolically active methanogen community composition during rumen development in black goats

open access: yesScientific Reports, 2017
This study was performed to investigate the initial colonization of metabolically active methanogens and subsequent changes in four fractions: the rumen solid-phase (RS), liquid-phase (RL), protozoa-associated (RP), and epithelium-associated (RE) from 1 ...

Airborne Observations Reveal Underestimated Riverine Methane Emissions Across the Amazon

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Strongly increasing trends in global methane in recent decades highlight the importance of understanding source‐sink attributions and climate feedback mechanisms, especially for large natural sources like wetlands. Here, we present an analysis of airborne methane observations above the Amazon Basin conducted from December 2022 through January ...

The effect of pretreatment on VFA production from tofu and tempeh wastewater through anaerobic digestion batch

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1743-1761, July/August 2026.
Abstract Tofu and tempeh, derived from soybeans, are widely consumed for their nutritional value and high protein content. However, the production of these foods generates nutrient‐rich wastewater that poses environmental challenges while offering opportunities for valorization.

Diversity and Functional Analysis of the FeMo-Cofactor Maturase NifB

open access: yesFrontiers in Plant Science, 2017
One of the main hurdles to engineer nitrogenase in a non-diazotrophic host is achieving NifB activity. NifB is an extremely unstable and oxygen sensitive protein that catalyzes a low-potential SAM-radical dependent reaction.

Biomethane Energy Production Using Orange Hydrogen Coupled With CO2 Sequestration and Utilization

open access: yesCarbon Neutralization, Volume 5, Issue 4, July 2026.
In subsurface hydrocarbon‐simulated environments, injected CO2 follows dual transformation routes: geochemical mineralization into stable carbonates (CCS) and microbially mediated conversion into CH4 energy through anaerobic metabolic processes. ABSTRACT The escalating concerns of global warming have intensified the global demand for clean energy ...

Methanogens dominate methanotrophs and act as a methane source in aquaculture pond sediments

open access: yesEcotoxicology and Environmental Safety
Aquaculture pond sediments act as hotspots for methane (CH4) emissions; however, knowledge gaps on the regulation of microorganisms hinder our further understanding of methane dynamics in aquaculture pond sediment.
