Anaerobic methane oxidation: Rate depth distributions in Skan Bay sediments [PDF]

, 1980
A radiotracer method that measures rates of oxidation of methane to carbon dioxide has been applied to anoxic marine sediments. The results confirm the occurrence of anaerobic methane oxidation and agree with model predictions of a zone of intense ...

Adoption of Minimum Tillage and Mid‐Season Drainage in Rice Production and Their Impacts on Farm and Economic Performance

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the effects of two greenhouse gas (GHG) mitigation practices—minimum tillage and mid‐season drainage—on rice farmers' farm performance (e.g., crop yield and risk) and economic outcomes (e.g., income and vulnerability).

Policy Evaluation for Climate Mitigations in the European Agricultural Sector—A Comparison of Policy Options at Micro and Macro Level

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT The purpose of this paper is to discuss the micro‐ and macro‐outcomes for the standard neoclassical carbon tax (whose burden falls on the producers) versus the implication of a budget neutral, performance‐based EU Common Agricultural Policy (CAP) focusing on non‐CO2 emission (N2O and CH4, measured in CO2eq) reduction, especially in the ...

Vertical distribution of methanotrophic archaea in an iron-rich groundwater discharge zone.

PLoS ONE
Anaerobic oxidation of methane coupled to iron reduction (Fe-AOM) is a crucial process for methane removal in terrestrial environments. However, the occurrence of Fe-AOM in natural environments is rare, and the mechanisms behind the direct coupling of ...

Awareness–Action and Policy Acceptability in Mitigating Greenhouse Gas Emissions: Key Stakeholders in Germany's Cattle Dairy and Meat Chains

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper presents a systematic literature review and targeted searches to define a synthesis framework mapping the awareness–action gap, progression along the awareness–action continuum and policy acceptability in greenhouse gas (GHG) emissions mitigation among key stakeholders in Germany's cattle dairy and meat chains.

Persistent activity of aerobic methane-oxidizing bacteria in anoxic lake waters due to metabolic versatility

Nature Communications
Lacustrine methane emissions are strongly mitigated by aerobic methane-oxidizing bacteria (MOB) that are typically most active at the oxic-anoxic interface.

Net methane oxidation performance of anaerobic sewage sludge

, 2020
The anaerobic oxidation of methane (AOM) in anaerobic sewage sludge was characterized. The net methane oxidation was observed in samples amended with methane plus sulfate or with methane alone, whereas methane formation was observed in the samples ...

Kaempferol Protects Intestinal Health in Chinese Forest Musk Deer Possibly by Regulating Intestinal Microbiota and Inhibiting the NF‐κB/NLRP3 Signaling Pathway

Integrative Zoology, EarlyView.
Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Anaerobic oxidation of short-chain alkanes in hydrothermal sediments: potential influences on sulfur cycling and microbial diversity

Frontiers in Microbiology, 2013
Short-chain alkanes play a substantial role in carbon and sulfur cycling at hydrocarbon-rich environments globally, yet few studies have examined the metabolism of ethane (C2), propane (C3), and butane (C4) in anoxic sediments in contrast to methane (C1).

Nitrogen-fixing methane-utilizing bacteria

, 1976
Methane occurs abundantly in nature. In the presence of oxygen this gas may be metabolized by bacteria that are able to use it as carbon and energy source.
