Extracellular electron transfer in bio-electrochemical systems (2008–2011)
Microbial conversions in sediments have a major impact on the emissions of greenhouse gasses and water quality. We will use bio-electrochemical systems, in which bacteria exchange electrons with electrodes, to study one of the potential key microbial processes, extracellular electron transfer, and its effect on biogeochemical cycles. We will gain insight in on how bacteria govern fluxes to and from their surroundings. The proteins produced by the bacteria will be investigated, to determine their role in extracellular electron transfer and their possible applications. Improving water quality and sustainable energy generation are long term outcomes of this project.
