Environment International, 2019 It has been reported that microbial reduction of sulfate, nitrite/nitrate and iron/manganese could be coupled with anaerobic oxidation of methane (AOM), which plays a significant role in controlling methane emission from anoxic niches. However, little is

Enzymes involved in the anaerobic oxidation of n-alkanes: from methane to long-chain paraffins
Frontiers in Microbiology, 2013 Anaerobic microorganisms play key roles in the biogeochemical cycling of methane and non-methane alkanes. To date, there appear to be at least three proposed mechanisms of anaerobic methane oxidation (AOM). The first pathway is mediated by consortia of

Plant, Soil and Environment, 2021 Quinones, redox-active functional groups in soil organic matter, can act as electron shuttles for microbial anaerobic transformation. Here, we used 13CH4 to trace 13C conversion (13C-CO2 + 13C-SOC) to investigate the influence of an artificial electron ...

A metagenomic study of methanotrophic microorganisms in Coal Oil Point seep sediments
BMC Microbiology, 2011 Background Methane oxidizing prokaryotes in marine sediments are believed to function as a methane filter reducing the oceanic contribution to the global methane emission.

Anaerobic Oxidation of Methane: Progress with an Unknown Process [PDF]
Annual Review of Microbiology, 2009 Methane is the most abundant hydrocarbon in the atmosphere, and it is an important greenhouse gas, which has so far contributed an estimated 20% of postindustrial global warming. A great deal of biogeochemical research has focused on the causes and effects of the variation in global fluxes of methane throughout earth's history, but the underlying ...

Anaerobic Methane Oxidation in a Landfill-Leachate Plume [PDF]
Environmental Science & Technology, 2002 The alluvial aquifer adjacent to Norman Landfill, OK, provides an excellent natural laboratory for the study of anaerobic processes impacting landfill-leachate contaminated aquifers. We collected groundwaters from a transect of seven multilevel wells ranging in depth from 1.3 to 11 m that were oriented parallel to the flow path.

Angewandte Chemie, EarlyView.Operando luminescence thermometry shows that the local catalyst temperature can exceed the set oven temperature by almost 250°C during the exothermic oxidative coupling of methane process. We demonstrate how the reactor dimensions, catalyst grain size, and reactant feed mixture affect the local temperature.
