Abstract
This study proposes a generalized model describing the temporal changes in open-circuit poten-tials in microbial biofilm systems. Using an Nernstian equilibrium approach combined with a series of different kinetic models for each experimental stage, it examines nutrient oxidation by microbes under anaerobic conditions with a continuous supply. New functions are derived to fit the experimental data and to provide in-depth understanding of the complex bioelectrochemical transformations occurring during the oxidation of nutrients by a biofilm.
