Electroactivity of Biofilms

 

Biofilms are one of the most prevalent life modes of microorganisms in natural and industrial settings. A decade ago, the biofilm formation on electrodes immersed into sediments was found to produce electrical current. Since then, motivated by the race to convert sediments and waste organic matter into electrical power fuels, many electrical fuel cells were engineered but their studies rapidly showed their limitation to generate power high enough to be useful. Few fundamental studies were published aside and the mechanisms by which electrons are produced by bacteria and transferred to the electrodes are still unknown. We would like to understand how biofilms produce currents by joining the matching experimental expertise of four different partners located in the campus Paris-Saclay (Christian Marlière (ISMO), Christophe Regeard (IGM), Renaud Cornut (NIMBE) and Eric Raspaud). The partners will focus on the biofilm conductivity, the electron and ion currents at multiple length scales.

 

A workshop on electroactivity of biological systems was organized under this context in November 2015.
