Inhibition of Rumen Methanogenesis and Ruminant Productivity: A Meta-Analysis [PDF]

Frontiers in Veterinary Science, 2018
Methane (CH4) formed in the rumen and released to the atmosphere constitutes an energy inefficiency to ruminant production. Redirecting energy in CH4 to fermentation products with a nutritional value to the host animal could increase ruminant ...

Review: Biological consequences of the inhibition of rumen methanogenesis

Animal
Decreasing enteric CH4 emissions from ruminants is important for containing global warming to 1.5 °C and avoid the worst consequences of climate change.

Diagnosing Anaerobic Digesters' Function and Performance: From Meta-Omics to Integrated Meta-Omics Analyses. [PDF]

Environ Microbiol Rep
The integration of multiple meta‐omics can tremendously improve our understanding of the structure, function and dynamics of the complex biological system in anaerobic digesters. Created in BioRender. https://BioRender.com/u9rj8ko. ABSTRACT Anaerobic digestion (AD) of organic wastes by microorganisms into biomethane contributes significantly towards ...

Isocyanides as a Chemical Tool for Identifying [Fe]-Hydrogenase-Dependent Methanogenesis. [PDF]

Chembiochem
In model methanogens, [Fe]‐hydrogenase (Hmd) substitutes nickel‐dependent hydrogenases under nickel‐limited conditions. We determined the inhibitory effects of the Hmd inhibitor, isocyanides, on methanogenesis in a cell extract and in a cell suspension.

Inhibition of methanogenesis by human bile. [PDF]

Gut, 1995
The factors that regulate methanogenesis in humans have not been established. The presence of bile acid, which is lost into the colon from the small intestine, may be an important regulatory factor of methanogenesis. To examine this possibility, the effect of human bile on methane production by faecal cultures, and the in vivo effect of biliary ...

Methanogenesis inhibition remodels microbial fermentation and stimulates acetogenesis in ruminants. [PDF]

Proc Natl Acad Sci U S A
Rumen microbiota enable ruminants to grow on fibrous plant materials, but also produce methane, driving 5% of global greenhouse gas emissions and leading to a loss of gross energy content. Methanogenesis inhibitors such as 3-nitrooxypropanol (3-NOP) decrease methane emissions in ruminants when supplemented in feed.

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.

Phosphate Inhibits Acetotrophic Methanogenesis on Rice Roots [PDF]

Applied and Environmental Microbiology, 2000
ABSTRACT The contribution of acetate- and H 2 /CO 2 -dependent methanogenesis to total CH 4 production was determined in excised washed rice roots by radiolabeling, methyl fluoride inhibition, and stable carbon isotope fractionation.

Inhibition of methanogenesis by nitrate, with or without defaunation, in continuous culture [PDF]

Journal of Dairy Science, 2020
Within the rumen, nitrate can serve as an alternative sink for aqueous hydrogen [H2(aq)] accumulating during fermentation, producing nitrite, which ideally is further reduced to ammonium but can accumulate under conditions not yet explained. Defaunation has also been associated with decreased methanogenesis in meta-analyses because protozoa contribute ...

Inhibition of Butyrate Oxidation by Formate during Methanogenesis [PDF]

Applied and Environmental Microbiology, 1993
A mixed methanogenic culture fed with glucose was perturbed with butyrate and formate to investigate the role of formate in the acetogenesis of butyrate. A free energy analysis suggests that formate rather than H 2 was the interspecies electron carrier for butyrate conversion into acetate for the culture studied.
