Living Microbial Catalysts at Modified Electrodes for Applications in Sustainable Energy Production and Bio-processes

Prof. Frédéric Barrière

 

Université de Rennes 1, France

 

Abstract

This seminar will discuss the use of living micro-organisms as electrode catalysts in fuel cells. We will address the underlying metabolic mechanisms for exo-cellular electron transfer at anodes (oxidation of organic substrates to carbon dioxide) and at cathodes (reduction of dioxygen to water). One of our interests in the field of bioelectrochemical systems is the rational tailoring of the microbial-electrode interface through surface modification in order to improve the development of electroactive biofilm and its electrical connection. Several examples of surface modification involving electrostatic or more specific interactions will be presented. Perspectives for applications as energy production, biosensing, wastewater treatment, etc. will be put forward.

Biographical Information

Prof. Frédéric Barrière has pursued a PhD in bioorganic chemistry in Brest, France until 1999. Afterwards, he stayed for two years as post-doc in Vermont, USA, working in the field of molecular electrochemistry followed by a stay in Galway, Ireland, where he worked in bio-electrochemistry. Since 2002, Frédéric Barrière is an associate professor at the University of Rennes 1. His current fields of research include bioinorganic chemistry, molecular electrochemistry and bioelectrochemistry. He pursues research on the design of enzymatic and microbial bio-fuel cells and the density functional theory modelling. In 2011, Frédéric Barrière obtained the Young Investigator Award in Electrochemistry from the French Chemical Society.
