Enzymes involved in the anaerobic oxidation of n-alkanes: from methane to long-chain paraffins

open access: yesFrontiers 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

Different impacts of an electron shuttle on nitrate- and nitrite-dependent anaerobic oxidation of methane in paddy soil

open access: yesPlant, 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 ...

Performance and genome-centric metagenomics of thermophilic single and two-stage anaerobic digesters treating cheese wastes [PDF]

open access: yes, 2018
The present research is the first comprehensive study regarding the thermophilic anaerobic degradation of cheese wastewater, which combines the evaluation of different reactor configurations (i.e. single and two-stage continuous stirred tank reactors) on

Anaerobic Oxidation of Methane: Progress with an Unknown Process [PDF]

open access: yesAnnual 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 ...

Artificial electron acceptors decouple archaeal methane oxidation from sulfate reduction [PDF]

open access: yes, 2016
The oxidation of methane with sulfate is an important microbial metabolism in the global carbon cycle. In marine methane seeps, this process is mediated by consortia of anaerobic methanotrophic archaea (ANME) that live in syntrophy with sulfate-reducing ...

Anaerobic Methane Oxidation in a Landfill-Leachate Plume [PDF]

open access: yesEnvironmental 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.

A metagenomic study of methanotrophic microorganisms in Coal Oil Point seep sediments

open access: yesBMC 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.

Alpha- and Gammaproteobacterial Methanotrophs Codominate the Active Methane-Oxidizing Communities in an Acidic Boreal Peat Bog [PDF]

open access: yes, 2016
The objective of this study was to characterize metabolically active, aerobic methanotrophs in an ombrotrophic peatland in the Marcell Experimental Forest, Minnesota, USA.

Anaerobic oxidation of methane: an “active” microbial process [PDF]

open access: yesMicrobiologyOpen, 2014
AbstractThe anaerobic oxidation of methane (AOM) is an important sink of methane that plays a significant role in global warming. AOM was first found to be coupled with sulfate reduction and mediated by anaerobic methanotrophic archaea (ANME) and sulfate‐reducing bacteria (SRB).

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]

open access: yes, 2008
Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...
