Identification of the Methanogenesis Inhibition Mechanism Using Comparative Analysis of Mathematical Models [PDF]

Frontiers in Bioengineering and Biotechnology, 2019
The application of cationic polymers to enhance membrane fluxes in anaerobic membrane bioreactors has been proposed by several authors. However, literature shows contradictory results on the influence of those chemicals on the biological activity.

Methanogenesis stimulation and inhibition for the production of different target electrobiofuels in microbial electrolysis cells through an on-demand control strategy using the coenzyme M and 2-bromoethanesulfonate

Environment International, 2019
Electron allocation through the suppression or the stimulation of methanogenesis is critical for microbial electrolysis cells (MECs) to produce the desired target product (e.g., CH4 or H2).

Salvianolic acid C inhibits methane emissions in dairy cows by targeting MCR and reshaping the rumen microbial community [PDF]

Journal of Animal Science and Biotechnology
Background Methane (CH4) emissions from ruminants significantly contribute to greenhouse gas effects and energy loss in livestock production. Methyl-coenzyme M reductase (MCR) is the key enzyme in methanogenesis, making it a promising target for CH4 ...

Time-series metatranscriptomics reveals differential salinity effects on the methanogenic food web in paddy soil [PDF]

mSystems
Saltwater intrusion and sea level rise (SWISLR) threaten coastal agroecosystems, yet their impact on the methanogenic food web in rice paddies remains virtually unknown.

Current Perspectives on Achieving Pronounced Enteric Methane Mitigation From Ruminant Production

Frontiers in Animal Science, 2022
Limiting global warming to 1.5°C above pre-industrial levels by 2050 requires achieving net zero emissions of greenhouse gases by 2050 and a strong decrease in methane (CH4) emissions.

Opportunities and Hurdles to the Adoption and Enhanced Efficacy of Feed Additives towards Pronounced Mitigation of Enteric Methane Emissions from Ruminant Livestock

Methane, 2022
This paper analyzes the mitigation of enteric methane (CH4) emissions from ruminants with the use of feed additives inhibiting rumen methanogenesis to limit the global temperature increase to 1.5 °C.

Review: Reducing enteric methane emissions improves energy metabolism in livestock: is the tenet right?

Animal, 2023
The production of enteric methane in the gastrointestinal tract of livestock is considered as an energy loss in the equations for estimating energy metabolism in feeding systems.

Methyl fluoride affects methanogenesis rather than community composition of methanogenic archaea in a rice field soil. [PDF]

PLoS ONE, 2013
The metabolic pathways of methane formation vary with environmental conditions, but whether this can also be linked to changes in the active archaeal community structure remains uncertain. Here, we show that the suppression of aceticlastic methanogenesis

Autotrophic Acetate Production under Hydrogenophilic and Bioelectrochemical Conditions with a Thermally Treated Mixed Culture

Membranes, 2022
Bioelectrochemical systems are emerging technologies for the reduction in CO2 in fuels and chemicals, in which anaerobic chemoautotrophic microorganisms such as methanogens and acetogens are typically used as biocatalysts.

A Review on the Interspecies Electron Transfer of Methane Production in Anaerobic Digestion System

Fermentation, 2023
Anaerobic methanogenesis plays an important role in the sustainable management of high concentration organic wastewater and bioenergy recovery. Interspecies electron transfer (IET) is a new type of mutualistic symbiosis that can accelerate microbial ...
