Influence of Diet on Methane and Nitrous Oxide Emissions from Cattle Manure

Asian Journal of Atmospheric Environment, 2015
Livestock is one of the major contributors of greenhouse gases (GHGs). It accounts for 14.5% of the global GHGs emissions like methane (CH4) from enteric fermentation and manure, nitrous oxide (N2O) from manure and fertilizer. Since enteric emissions are

Seaweed supplementation to organic dairy cows may reduce climate impact of manure in pasture soils during a laboratory incubation

Journal of Sustainable Agriculture and Environment, 2023
Introduction Enteric methane (CH4) emissions are one of the largest components of the anthropogenic CH4 budget, and with accelerating climatic changes, there are calls to reduce anthropogenic greenhouse gas emissions.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Estimating methane emissions from manure: a suitable case for treatment?

Environmental Research: Food Systems
Methane from livestock is a significant source of greenhouse gas emissions. Under the UN Framework Convention on Climate Change (UNFCCC), Annex I countries’ National Inventories report emissions from cattle as enteric or from manure management at ratios ...

Cryo‐EM Structures Reveal the Molecular Basis of Asymmetric Allosteric Activation by MMOB in the Hydroxylase of Soluble Methane Monooxygenase

Advanced Science, EarlyView.
Cryo‐EM analysis reveals an asymmetric MMOH–MMOB complex with distinct protomers, where MMOB binding triggers structural rearrangements from the surface to the active site. This conformational asymmetry shortens the Fe···Fe distance to 2.7 Å in one protomer, forming a geometry suitable for O2 activation and supporting a sequential catalytic mechanism ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

Advanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

Methyl coenzyme M reductase as a target for inhibition of methanogenesis in ruminants: challenges and opportunities

Frontiers in Microbiology
Enteric methane from ruminants is a major source of greenhouse gasses (GHG) emissions globally, and its formation also leads to a decrease in animals’ productivity due to loss of dietary energy.
