Aerobic and anaerobic methane oxidation in a seasonally anoxic basin

Limnology and Oceanography, 2022
AbstractShallow coastal waters are dynamic environments that dominate global marine methane emissions. Particularly high methane concentrations are found in seasonally anoxic waters, which are spreading in eutrophic coastal systems, potentially leading to increased methane emissions to the atmosphere.

Anaerobic methane oxidation and aerobic methane production in an east African great lake (Lake Kivu) [PDF]

Journal of Great Lakes Research, 2018
Abstract We investigated CH4 oxidation in the water column of Lake Kivu, a deep meromictic tropical lake with CH4-rich anoxic deep waters. Depth profiles of dissolved gases (CH4 and N2O) and a diversity of potential electron acceptors for anaerobic CH4 oxidation (NO3−, SO42−, Fe and Mn oxides) were determined during six field campaigns between June ...

Geographic and seasonal variation of dissolved methane and aerobic methane oxidation in Alaskan lakes [PDF]

Biogeosciences, 2015
Abstract. Methanotrophic bacteria play an important role oxidizing a significant fraction of methane (CH4) produced in lakes. Aerobic CH4 oxidation depends mainly on lake CH4 and oxygen (O2) concentrations, in such a manner that higher MO rates are usually found at the oxic/anoxic interface, where both molecules are present.

A mathematical model of aerobic methane oxidation coupled to denitrification

Environmental Technology, 2017
Aerobic methanotrophic bacteria use methane as their only source of energy and carbon. They release organic compounds that can serve as electron donors for co-existing denitrifiers. This interaction between methanotrophs and denitrifiers is known to contribute to nitrogen losses in natural environments and has also been exploited by researchers for ...

Members of the Genus Methylobacter Are Inferred To Account for the Majority of Aerobic Methane Oxidation in Oxic Soils from a Freshwater Wetland. [PDF]

mBio, 2018
Here we used soil metagenomics and metatranscriptomics to uncover novel members within the genus Methylobacter. We denote these closely related genomes as members of the lineage OWC Methylobacter. Despite the incredibly high microbial diversity in soils,

Persistent activity of aerobic methane-oxidizing bacteria in anoxic lake waters due to metabolic versatility

Nature Communications
Lacustrine methane emissions are strongly mitigated by aerobic methane-oxidizing bacteria (MOB) that are typically most active at the oxic-anoxic interface.

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 ...

Forecasting wind speed data by using a combination of ARIMA model with single exponential smoothing [PDF]

, 2021
Wind serves as natural resources as the solution to minimize global warming and has been commonly used to produce electricity. Because of their uncontrollable wind characteristics, wind speed forecasting is considered one of the best challenges in ...

Identification of functionally active aerobic methanotrophs and their methane oxidation potential in sediments from the Shenhu Area, South China Sea

China Geology, 2022
: Large amounts of gas hydrate are distributed in the northern slope of the South China Sea, which is a potential threat of methane leakage. Aerobic methane oxidation by methanotrophs, significant methane biotransformation that occurs in sediment surface

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.
