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.

The fate of methane in ponds: Drivers of production, storage, oxidation, and emissions

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Ponds are disproportionately large contributors to global carbon cycling, with substantial but variable emissions of methane (CH4) to the atmosphere relative to their global surface area. Efforts to upscale pond CH4 emissions have focused on broad‐scale correlates of emissions, yet mechanisms underlying the variability in emissions remain ...

Methanogenesis inhibition by phosphorus in anaerobic liquid waste treatment

Waste Treatment and Recovery, 2017
Abstract The effect of a sudden influent phosphorus concentration increase on a completely mixed reactor of an anaerobic liquid waste treatment process was evaluated. Chemical oxygen demand (COD), volatile fatty acids (VFA), suspended solids, pH and gas production were measured for process monitoring.

Characterisation and microbial community analysis of lipid utilising microorganisms for biogas formation.

PLoS ONE, 2019
In the anaerobic process, fat-oil-grease (FOG) is hydrolysed to long-chain fatty acids (LCFAs) and glycerol (GLYC), which are then used as substrates to produce biogas.

Carbon Monoxide Inhibition on Acidogenic Glucose Fermentation and Aceticlastic Methanogenesis

Bioresource Technology
Syngas and CO-rich off-gases are key chemical platforms to produce biofuels and bioproducts. From the perspective of optimizing and up-scaling CO co-digestion with organic waste streams, this study aims at assessing and quantifying the inhibitory effects of CO on acidogenic glucose fermentation and aceticlastic methanogenesis.

Insights into the Feed Additive Inhibitor and Alternative Hydrogen Acceptor Interactions: A Future Direction for Enhanced Methanogenesis Inhibition in Ruminants

Fermentation
Enteric methane (CH4) emissions from ruminants contribute significantly to agricultural greenhouse gases. Anti-methanogenic feed additives (AMFA), such as Asparagopsis spp.

Combination of methane-inhibitors and hydrogen-acceptors: effects on in vitro rumen fermentation

Italian Journal of Animal Science
Methanogenesis inhibition in vivo is often associated with higher dihydrogen (H2) emission without an increase in production efficiency. The objectives of this in vitro study were to test the effects of the addition of iodoform (IOD; 0.007% w/w on DM ...

Limits to dihydrogen incorporation into electron sinks alternative to methanogenesis in ruminal fermentation

Frontiers in Microbiology, 2015
Research is being conducted with the objective of decreasing methane (CH4) production in the rumen, as methane emissions from ruminants are environmentally damaging and a loss of digestible energy to ruminants. Inhibiting ruminal methanogenesis generally
