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.

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.

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 ...

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.

Inhibiting Methanogenesis Stimulated de novo Synthesis of Microbial Amino Acids in Mixed Rumen Batch Cultures Growing on Starch but not on Cellulose

Microorganisms, 2020
Ameliorating methane (CH4) emissions from ruminants would have environmental benefits, but it is necessary to redirect metabolic hydrogen ([H]) toward useful sinks to also benefit animal productivity.

Organic matter supply and bacterial community composition predict methanogenesis rates in temperate lake sediments

Limnology and Oceanography Letters, 2019
The objective of our study was to identify environmental conditions that structure lake sediment microbial communities and determine whether community composition explained inter‐lake variation in potential methanogenesis rates.

User-friendly mathematical model for the design of sulfate reducing H2/CO2 fed bioreactors [PDF]

, 2009
The paper presents three steady-state mathematical models for the design of H2/CO2 fed gas-lift reactors aimed at biological sulfate reduction to remove sulfate from wastewater. Models 1A and 1B are based on heterotrophic sulfate reducing bacteria (HSRB),

A multienzyme complex channels substrates and electrons through acetyl-CoA and methane biosynthesis pathways in Methanosarcina.

PLoS ONE, 2014
Multienzyme complexes catalyze important metabolic reactions in many organisms, but little is known about the complexes involved in biological methane production (methanogenesis). A crosslinking-mass spectrometry (XL-MS) strategy was employed to identify
