Quantification of methane oxidation in the rice rhizosphere using 13C-labelled methane [PDF]

open access: yes, 1994
In this paper isotope ratio mass spectrometry is used to determine the methane (CH4) oxidation fraction in the rhizosphere of intact rice plant-soil systems.

Increasing the Production of Volatile Fatty Acids from Corn Stover Using Bioaugmentation of a Mixed Rumen Culture with Homoacetogenic Bacteria

open access: yesMicroorganisms, 2021
Volatile fatty acids (VFA) are industrially versatile chemicals and have a major market. Although currently produced from petrochemicals, chemical industries are moving towards more bio-based VFA produced from abundant, cheap and renewable sources such ...

Quantifying temporal dynamics of greenhouse gas emissions in lake mesocosms: Deployment of a low‐cost measurement system

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

3-Nitrooxypropanol substantially decreased enteric methane emissions of dairy cows fed true protein- or urea-containing diets

open access: yesHeliyon, 2022
Methane is a potent but short-lived greenhouse gas targeted for short-term amelioration of climate change, with enteric methane emitted by ruminants being the most important anthropogenic source of methane.

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.

Seasonal Variation in Carbon Dynamics in the Lower Tocantins River: Influence of Discharge and Environmental Drivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Tropical rivers play a key role in regional carbon budgets, yet greenhouse gas (GHG) dynamics in regulated systems remain poorly understood. This study investigates the seasonal variability of carbon dioxide (CO2) and methane (CH4) concentrations, isotopic composition (δ13C), and river‐atmosphere fluxes in the lower Tocantins River, a ...

Oxygen sensitivity of methanogenesis in rumen and anaerobic digester populations using mass spectrometry [PDF]

open access: yes, 1983
Membrane inlet mass spectrometry has been used to determine the effect of oxygen on methanogenesis in samples from a rumen and an anaerobic digester. A membrane covered Photobacterium probe, in conjunction with the mass spectrometer, was used to measure ...

Understanding Farmer Behaviour for Successful Climate Change Mitigation in Voluntary Initiatives

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Private and voluntary initiatives, such as voluntary carbon markets, can support public policies aimed at reducing greenhouse gas (GHG) emissions in agriculture. This study investigates the impact of behavioural factors (reluctance to change) and social dynamics (peer imitation) on the adoption of two mitigation practices on Swiss dairy and ...

Table_1_Inhibition of Rumen Methanogenesis and Ruminant Productivity: A Meta-Analysis.docx [PDF]

open access: yes, 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 ...

The use of direct-fed microbials for mitigation of ruminant methane emissions: a review

open access: yesAnimal, 2014
Concerns about the environmental effect and the economic burden of methane (CH4) emissions from ruminants are driving the search for ways to mitigate rumen methanogenesis.
