Size matters: Aerobic methane oxidation in sediments of shallow thermokarst lakes

Global Change Biology, 2023
AbstractShallow thermokarst lakes are important sources of greenhouse gases (GHGs) such as methane (CH4) and carbon dioxide (CO2) resulting from continuous permafrost thawing due to global warming. Concentrations of GHGs dissolved in water typically increase with decreasing lake size due to coastal abrasion and organic matter delivery.

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.

Evaluation of Methyl Fluoride and Dimethyl Ether as Inhibitors of Aerobic Methane Oxidation [PDF]

Applied and Environmental Microbiology, 1992
Methyl fluoride (MF) and dimethyl ether (DME) were effective inhibitors of aerobic methanotrophy in a variety of soils. MF and DME blocked consumption of CH 4 as well as the oxidation of 14 CH 4 to 14 CO 2 , but neither ...

Thermophilic methane oxidation is widespread in Aotearoa-New Zealand geothermal fields

Frontiers in Microbiology, 2023
Geothermal areas represent substantial point sources for greenhouse gas emissions such as methane. While it is known that methanotrophic microorganisms act as a biofilter, decreasing the efflux of methane in most soils to the atmosphere, the diversity ...

A New Spin on Photocatalysis: Vortex Fluidic‐Driven Photooxidations Enabled by Solution‐Processable Microporous Polymers

Chemistry – A European Journal, EarlyView.
Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

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 ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Investigation on the aerobic methanotrophic community and the dominant taxon Methylomarinum in seagrass ecosystem

Environmental Microbiome
Background Methanotrophs are a key biological methane sink, and aerobic methanotrophs critically reduce wetland methane emissions under global climate change.
