Microbial fuel cells (MFCs) are attracting considerable attention as innovative systems for energy production from renewable residual biomass and biomass-derived wastes. Current produced by a microbial fuel cell can also be used to quantify the rate of specific metabolic processes and the substrate concentration in real time. Aim of this work is to develop a MFC based biosensor for real time quantification of organic biodegradable substrates at low concentration, in the rage of 0-100 mg/L COD. In a continuous flow membraneless MFC, a concentration-dependent current output was achieved using sodium acetate as organic substrate. Furthermore, Monod kinetics was observed as the best-fitting model.

Abstract
Microbial fuel cells (MFCs) are attracting considerable attention as innovative systems for energy production from renewable residual biomass and biomass-derived wastes. Current produced by a microbial fuel cell can also be used to quantify the rate of specific metabolic processes and the substrate concentration in real time. Aim of this work is to develop a MFC based biosensor for real time quantification of organic biodegradable substrates at low concentration, in the rage of 0-100 mg/L COD. In a continuous flow membraneless MFC, a concentration-dependent current output was achieved using sodium acetate as organic substrate. Furthermore, Monod kinetics was observed as the best-fitting model.
