Tools for decreasing enteric methane production by ruminants

, 2011
This paper reviews the strategies to reduce methanogenesis in ruminants and their applicability on farm. It is known that increasing the percentage of concentrate decreases the production of methane per kg of dry matter intake. This effect is especially important at high levels of concentrate.

Low Greenhouse Gas Agriculture: Mitigation and Adaptation Potential of Sustainable Farming Systems [PDF]

, 2009
Is low greenhouse gas emission (GHG) agriculture possible? Is it, in fact, desirable? In seeking answers to these two basic but extremely relevant questions, this study examines current farming practices, and incorporates scientific databases from ...

Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

Energy Science &Engineering, EarlyView.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the

Current Advancements of Probiotic Foods and Their Role in Sustainable Food Security

Food Bioengineering, EarlyView.
ABSTRACT Probiotic foods have evolved from traditional fermented products to scientifically validated functional foods, defined by the FAO and WHO as live microorganism that confer a health benefit on the host when administered in adequate amounts, with effects being strain, does and end point specific.

Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances

Effet de l’huile de tournesol sur l’émission de méthane entérique chez la vache laitière

Revue Marocaine des Sciences Agronomiques et Vétérinaires, 2015
The objective of this study is to evaluate the effect of sunflower oil on enteric methane emissions in dairy cows. Fermentation in the digestive tract of ruminants contributes about 18% of world production of this potent greenhouse gas.

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Resistome flow in global landfill systems

iMetaOmics, EarlyView.
Global landfill systems represent key hubs of resistome, serving as dynamic reservoirs and amplifiers through plasmid‐driven gene mobility. Waste flows and environmental pathways sustain the transboundary resistome networks, accelerating resistance dissemination across ecosystems.

The role of the gut microbiome in the regulation of high‐altitude adaptation

iMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...
