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: an “active” microbial process [PDF]

MicrobiologyOpen, 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).

Vertical distribution of methane oxidation and methanotrophic response to elevated methane concentrations in stratified waters of the Arctic fjord Storfjorden (Svalbard, Norway) [PDF]

, 2013
The bacterially mediated aerobic methane oxidation (MOx) is a key mechanism in controlling methane (CH₄) emissions from the world’s oceans to the atmosphere.

Methane-yielding microbial communities processing lactate-rich substrates: a piece of the anaerobic digestion puzzle

Biotechnology for Biofuels, 2018
Background Anaerobic digestion, whose final products are methane and carbon dioxide, ensures energy flow and circulation of matter in ecosystems. This naturally occurring process is used for the production of renewable energy from biomass.

Microbial Communities Involved in Methane, Sulfur, and Nitrogen Cycling in the Sediments of the Barents Sea

Microorganisms, 2021
A combination of physicochemical and radiotracer analysis, high-throughput sequencing of the 16S rRNA, and particulate methane monooxygenase subunit A (pmoA) genes was used to link a microbial community profile with methane, sulfur, and nitrogen cycling ...

A novel identified Pseudomonas aeruginosa, which exhibited nitrate‐ and nitrite‐dependent methane oxidation abilities, could alleviate the disadvantages caused by nitrate supplementation in rumen fluid fermentation

Microbial Biotechnology, 2021
Summary After the occurrence of nitrate‐dependent anaerobic methane oxidation (AMO) in rumen fluid culture was proved, the organisms that perform the denitrifying anaerobic methane oxidizing (DAMO) process in the rumen of dairy goat were investigated by ...

Trace element requirements for stable food waste digestion at elevated ammonia concentrations [PDF]

, 2012
The work investigated why anaerobic digesters treating food waste and operating at high ammonia concentrations suffer from propionic acid accumulation which may result in process failure.

A Critical Look at the Combined Use of Sulfur and Oxygen Isotopes to Study Microbial Metabolisms in Methane-Rich Environments

Frontiers in Microbiology, 2018
Separating the contributions of anaerobic oxidation of methane and organoclastic sulfate reduction in the overall sedimentary sulfur cycle of marine sediments has benefited from advances in isotope biogeochemistry.

Light-Dependent Aerobic Methane Oxidation Reduces Methane Emissions from Seasonally Stratified Lakes. [PDF]

PLoS ONE, 2015
Lakes are a natural source of methane to the atmosphere and contribute significantly to total emissions compared to the oceans. Controls on methane emissions from lake surfaces, particularly biotic processes within anoxic hypolimnia, are only partially ...

Carbon capture and biogas enhancement by carbon dioxide enrichment of anaerobic digesters treating sewage sludge or food waste [PDF]

, 2014
The increasing concentration of carbon dioxide (CO2) in the atmosphere and the stringent greenhouse gases (GHG) reduction targets, require the development of CO2 sequestration technologies applicable for the waste and wastewater sector.
