MECOMECON: Methanotrophic diversity and gene expression as a controlling factor of global methane consumption

Projekttitel:

Field-scale and laboratory evaluation of structural and functional stability (resistance and resilience) of methanotrophic communities in a landfill-cover soil

Keywords:

Methane oxidation, methanotrophs, community stability, greenhouse gas, landfill

Lead (Kurzzusammenfassung, 40 Worte):

Impacts of the highly potent greenhouse gas methane are mitigated by the activity of methane-consuming microorganisms. This project will investigate the effects of changing environmental factors on the diversity and functioning of such methanotrophic communities in a landfill-cover soil.   

Hintergrund (100-150 Worte):

Methane (CH4) is one of the most abundant greenhouse gases in the atmosphere with a significantly higher global-warming potential than CO2. The global CH4 budget is dominated by biogenic sources (natural wetlands, rice fields, ruminants and termites, landfills and other waste treatment systems) where methanogenic microorganisms produce CH4 from organic substances. The effects of this anaerobic microbial CH4 production are mitigated by the activity of aerobic methane-oxidizing bacteria (so-called methanotrophs), which globally consume approximately 50% of the generated CH4. In landfill-cover soils, microbial oxidation of CH4, which migrates upwards from the source towards the surface, ranges from 10% - 100%. The activity of methanotrophs in these landfill soils is influenced by a range of different factors (e.g. location, soil moisture content or temperature). Unfortunately, very little is known regarding the effects of environmental changes on the stability of methanotrophic communities in landfills and how these factors affect their field-scale performance.

Ziel (50-70 Worte):

The aim of this project is to assess the structural and functional stability of methanotrophs in a Swiss landfill-cover soil (Liestal, Kanton Basel) that is subjected to fluctuations in substrates and temperature. Methanotrophic activity and diversity will be analyzed over time at field scale and under laboratory conditions, using tools such as the newly-developed gas push-pull test to quantify methane consumption in soils and a variety of molecular biological techniques.

Bedeutung (50-100 Worte):

Methane is a highly potent greenhouse gas that contributes to the effects of global warming. Microbial methane consumption significantly reduces these effects, and natural methanotrophic communities play a vital role in the global climate and support essential ecosystem services. As part of a multi-disciplinary European collaboration (European Science Foundation EUROCORES Program; www.mecomecon.org) this project will contribute to a better understanding of the effects of changing environmental factors (e.g. temperature, water content) on the stability and functioning of methanotrophic communities and therefore the amount of methane that is released into the atmosphere.
