摘要: Abstract Microbial fuel cells (MFCs) provide an alternative approach to generate electricity from organic matter. In these MFCs, microorganisms such as the Geobacter species oxidize waste and transfer electrons electrode. Mathematical models have been used study optimize biofilm processes, in developing MFCs into commercial applications. Existing are based on Nernst-Monod type expressions, restricted studying extracellular behavior electrochemical microbiological components, separated metabolic of or vice versa. This paper presents a model that addresses spatial heterogeneity across biofilm, while incorporating fluxes each individual cell conditions (electron donor acceptor concentrations) vary biofilm. shows effect different maintenance energy requirements maximum current production thickness biofilms, predicts variations thicknesses DL1 KN400 strains under similar conditions, successfully.
