Study on Oxidation Rate and Isotope Fractionation of Methane in Bohai Sea Sediments

Yankuang ceshi, 2018
BACKGROUND:The Bohai Sea contains a large amount of oil and gas, the main component of which is methane. The influence of natural or human factors will cause its leakage and migration and then have a negative impact on the environment.

Impact of Electron Acceptor Availability on Methane-Influenced Microorganisms in an Enrichment Culture Obtained From a Stratified Lake

Frontiers in Microbiology, 2020
Methanotrophs are of major importance in limiting methane emissions from lakes. They are known to preferably inhabit the oxycline of stratified water columns, often assumed due to an intolerance to atmospheric oxygen concentrations, but little is known ...

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]

, 2019
Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Research on index gas and activation energy of coal spontaneous combustion under different methane atmosphere

Gong-kuang zidonghua, 2019
Most researches on coal spontaneous combustion characteristics under different oxygen concentration only consider different oxygen nitrogen ratio atmosphere, but low temperature oxidation law of coal under different methane atmospheres is seldom studied.

Ammonium Impacts Methane Oxidation and Methanotrophic Community in Freshwater Sediment

Frontiers in Bioengineering and Biotechnology, 2020
Lacustrine ecosystems are regarded as one of the important natural sources of greenhouse gas methane. Aerobic methane oxidation, carried out by methane-oxidizing bacteria, is a key process regulating methane emission.

Biotechnological aspects of sulfate reduction with methane as electron donor [PDF]

, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

An investigation of the comparative reactivities of ethane and ethylene in the presence of oxygen over Li/MgO and Ca/Sm2O3 catalysts in relation to the oxidative coupling of methane [PDF]

, 1989
In order to examine the importance of the further oxidation of the desired C2 products in the oxidative coupling of methane, ethylene and ethane have been added to the feed (containing methane and oxygen) to a Li/MgO or Ca/Sm2O3 catalyst.

Inhibition of methane oxidation by nitrogenous fertilizers in a paddy soil

Frontiers in Microbiology, 2012
Nitrogenous fertilizers are generally thought to have an important role in regulating methane oxidation. In this study, the effect of ammonium on methane oxidation activity was investigated in a paddy soil using urea at concentrations of 0, 50, 100, 200 ...
