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.

Inhibiting Methanogenesis in Rumen Batch Cultures Did Not Increase the Recovery of Metabolic Hydrogen in Microbial Amino Acids

Microorganisms, 2019
There is an interest in controlling rumen methanogenesis as an opportunity to both decrease the emissions of greenhouse gases and improve the energy efficiency of rumen fermentation. However, the effects of inhibiting rumen methanogenesis on fermentation

Microbial methanogenesis in the sulfate-reducing zone of surface sediments traversing the Peruvian margin [PDF]

Biogeosciences, 2016
We studied the concurrence of methanogenesis and sulfate reduction in surface sediments (0–25 cm below sea floor) at six stations (70, 145, 253, 407, 990 and 1024 m) along the Peruvian margin (12° S).

The effect of 3-nitrooxypropanol, a potent methane inhibitor, on ruminal microbial gene expression profiles in dairy cows

Microbiome, 2022
Background Enteric methane emissions from dairy cows are an environmental problem as well as a gross feed energy loss to the animal. Methane is generated in the rumen by methanogenic archaea from hydrogen (H2) + carbon dioxide and from H2 + methanol or ...

Direct interspecies electron transfer enables anaerobic oxidation of sulfide to elemental sulfur coupled with CO2-reducing methanogenesis

iScience, 2023
Summary: Electric syntrophy between fatty acid oxidizers and methanogens through direct interspecies electron transfer (DIET) is essential for balancing acidogenesis and methanogenesis in anaerobic digestion.

Electron Bifurcation and Confurcation in Methanogenesis and Reverse Methanogenesis

Frontiers in Microbiology, 2018
Reduction of the disulfide of coenzyme M and coenzyme B (CoMS–SCoB) by heterodisulfide reductases (HdrED and HdrABC) is the final step in all methanogenic pathways. Flavin-based electron bifurcation (FBEB) by soluble HdrABC homologs play additional roles

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

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 ...

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.

Effects of Copper Sulfate and Encapsulated Copper Addition on In Vitro Rumen Fermentation and Methane Production

Agriculture, 2022
Copper is a microelement crucial for the proper functioning of animals’ metabolic processes. The function of copper in rumen fermentation processes and methanogenesis is not well analyzed.
