Hydrological seasonality shapes microbial biomass and diversity in an equatorial estuarine mangrove

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Mangroves are pantropical marine forests rooted in soft sediments and subject to pronounced seasonal variability. However, the effects of these hydrological fluctuations on root‐associated prokaryotic communities remain poorly understood, particularly in underexplored regions like the Guianas.

Inhibition of methane production in microbial fuel cells:Operating strategies which select electrogens over methanogens [PDF]

, 2014
Methanogenesis may diminish coulombic efficiency of microbial fuel cells (MFCs), although its importance is application dependent; e.g., suppression of methanogenesis may improve MFC sensing accuracy, but may be tolerable in COD removal from wastewaters.

Inhibition of enteric methanogenesis in dairy cows induces changes in plasma metabolome highlighting metabolic shifts and potential markers of emission [PDF]

, 2020
International audienceThere is scarce information on whether inhibition of rumen methanogenesis induces metabolic changes on the host ruminant. Understanding these possible changes is important for the acceptance of methane-reducing practices by ...

Overcoming Extreme Ammonia Inhibition on Methanogenesis by Artificially Constructing a Synergistically Community with Acidogenic Bacteria and Hydrogenotrophic Archaea

Advanced Science
High total ammonia nitrogen (TAN) inhibits anaerobic digestion (AD) and cannot be completely eliminated by merely enhancing a stage of AD. This study incorporates TAN‐tolerant inoculum into substrates hydrolyzed by Rhizopus mixed agents to simultaneously

A theoretical comparison between two ruminal electron sinks

Frontiers in Microbiology, 2013
Dihydrogen accumulation resulting from methanogenesis inhibition in the rumen is an energy loss and can inhibit fermentation. The objective of this analysis was to compare the energetic and nutritional consequences of incorporating H2 into reductive ...

Enhanced methane production by alleviating sulfide inhibition with a microbial electrolysis coupled anaerobic digestion reactor

Environment International, 2020
Anaerobic digestion (AD) of organics is a challenging task under high-strength sulfate (SO42−) conditions. The generation of toxic sulfides by SO42−-reducing bacteria (SRB) causes low methane (CH4) production.

Gut Microbiota as a Key Modulator in the Pathophysiology of Sepsis: SURVEIL Project

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Longitudinal profiling of 132 hospitalized patients reveals that age, colonization status, and sepsis interact to shape gut microbiota diversity and composition. Sepsis is associated with reduced alpha diversity, beta‐diversity shifts, functional predictions (methanogenesis, nitrate/sulfate respiration), and partial MDR overlap with bloodstream ...

Inhibition of Methanogenesis in Rumen Fluid Cultures [PDF]

, 2006
We identified 32 compounds that inhibit 13 to 100% of the methane produced by in vitro cultures of rumen fluid and have the potential to inhibit enteric methanogenesis in ruminant animals.

Ammonia stress decreased biomarker genes of acetoclastic methanogenesis and second peak of production rates during anaerobic digestion of swine manure [PDF]

, 2020
Research shows that anaerobic digestion could acclimate to ammonia stress; however, the acclimation remained unaddressed. In this study, evolution of microbial community, functional gene, and pathway was linked with apparent kinetic and performance in ...

Jump in Tropospheric Methane Concentrations in 2020–2021 and Slowdown in 2022–2024: New Hypotheses on Causation

Atmosphere
Earth’s atmospheric methane (CH4) concentration has risen more than 162% since pre-industrial levels in the mid-18th century, and about 30% of the rise in global temperatures since the pre-industrial era is due to CH4 The build-up of methane in the ...
