The research of Haluk Beyenal’s group was recently featured on the cover of the Journal of the Electrochemical Society. Fumarate microbiosensor is a microscale biosensor capable of detecting fumarate at micromolar level in biofilms. The working principle is the correlation between fumarate concentration and current consumption during fumarate reduction by Geobacter sulfurreducens biofilms grown on a carbon microelectrode tip. In addition to biofilm applications, the microbiosensor can be used in various anaerobic applications such as in a wastewater treatment system during anaerobic conversion processes in which fumarate is used as an electron acceptor.
