Catchment Influences on Carbon Stable Isotope Variation in Trout; Might It Be Methane? [PDF]
Trout stable carbon isotope values vary significantly and appear to relate to catchment characteristics. Low carbon stable isotope values are linked to catchments with low drainage soil and high cover of pasture land use. This is likely to be linked to high levels of methane‐derived carbon entering the stream food web.

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

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

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

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]
Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

Isoprene oxidation by the gram-negative model bacterium variovorax sp. WS11 [PDF]
Plant-produced isoprene (2-methyl-1,3-butadiene) represents a significant portion of global volatile organic compound production, equaled only by methane.

A mathematical model of aerobic methane oxidation coupled to denitrification
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 ...
