Microbial contributions to methane cycling
Session ID#: 83663
Session Description:
Methane, as a greenhouse gas, is the second highest contributor to global climate change and has a significantly higher global warming potential than carbon dioxide. Microbial processes contribute to the release and consumption of methane in diverse environments and can impact the global methane budget. Understanding methane-cycling microbial communities methane cycling and their contribution to the bioconversion of methane to other one-carbon (C1) metabolites, will allow for the generation of better models to predict future methane flux. Biogeochemistry and environmental conditions can dictate the thermodynamics of methane metabolism and the microbial communities that contribute. New approaches and tools including single cell analyses are making it possible to detect methane-cycling organisms in environments of interest. We invite abstracts on laboratory, modeling and field studies focusing on microbial communities contributing to methane consumption and production, as well as the biogeochemical drivers and controls for these processes in diverse environments.
