Waterfalls enhance regional methane emissions by enabling dissolved methane to bypass microbial oxidation

Communications Earth & Environment
River waters are significant sources of atmospheric methane whose local emissions increase with river slope and turbulence. However, when integrated regionally, the amount of dissolved methane released to the atmosphere is uninfluenced by local changes ...

Methane Oxidation via Chemical and Biological Methods: Challenges and Solutions

Methane, 2023
Methane, a potent greenhouse gas, has gained significant attention due to its environmental impact and economic potential. Chemical industries have focused on specialized catalytic systems, like zeolites, to convert methane into methanol.

Oxidation is a potentially significant methane sink in land-terminating glacial runoff

Scientific Reports
Globally, aquatic ecosystems are one of the largest but most uncertain sources of methane, a potent greenhouse gas. It is unclear how climate change will affect methane emissions, but recent work suggests that glacial systems, which are melting faster ...

THERMODYNAMIC ANALYSIS OF SYNTHESIS GAS AND HIGHER HYDROCARBONS PRODUCTION FROM METHANE [PDF]

, 2012
This chapter focused on thermodynamic chemical equilibrium analysis using method of direct minimization of Gibbs free energy for all possible methane reactions with oxygen (partial oxidation of methane), carbon dioxide (CO2 reforming of methane), steam ...

Soil methane sink capacity response to a long-term wildfire chronosequence in Northern Sweden [PDF]

, 2015
Boreal forests occupy nearly one fifth of the terrestrial land surface and are recognised as globally important regulators of carbon (C) cycling and greenhouse gas emissions.

ISOLATION AND CHARACTERIZATION OF METHANOTROPHIC BACTERIA FROM RICE FIELDS

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011
Methane is a greenhouse gas and has potency to deplete ozone layer.  Rice fields are a significantly sources of atmospheric methane.  Chemical fertilizers application in rice fields can increase methane emission.

In Vivo Evidence of Single 13C and 15N Isotope–Labeled Methanotrophic Nitrogen-Fixing Bacterial Cells in Rice Roots

mBio, 2022
Methane-oxidizing bacteria (methanotrophs) play an ecological role in methane and nitrogen fluxes because they are capable of nitrogen fixation and methane oxidation, as indicated by genomic and cultivation-dependent studies.

Oxidative coupling of methane in a mixed-conducting perovskite membrane reactor [PDF]

, 1995
Ionic-electronic mixed-conducting perovskite-type oxide La0.6Sr0.4Co0.8Fe0.2O3 was applied as a dense membrane for oxygen supply in a reactor for methane coupling.

RNA Biomarker Trends across Type I and Type II Aerobic Methanotrophs in Response to Methane Oxidation Rates and Transcriptome Response to Short-Term Methane and Oxygen Limitation in Methylomicrobium album BG8

Microbiology Spectrum, 2022
Methanotrophs, which help regulate atmospheric levels of methane, are active in diverse natural and man-made environments. This range of habitats and the feast-famine cycles seen by many environmental methanotrophs suggest that methanotrophs dynamically ...

Assessing connectivity between an overlying aquifer and a coal seam gas resource using methane isotopes, dissolved organic carbon and tritium [PDF]

, 2015
Coal seam gas (CSG) production can have an impact on groundwater quality and quantity in adjacent or overlying aquifers. To assess this impact we need to determine the background groundwater chemistry and to map geological pathways of hydraulic ...
