Abstract

A mathematical model for anodic electricicigen bacteria useful for Microbial Electrolysis Cells (MEC)
and Microbial Fuel Cells (MFC) is proposed on the base of global mass balances of the different
species present in these systems and considering that all the involved microorganisms are attached
to the anodic biological film. Three main biological reactions are introduced, which are obtained
from the solution of partial differential equations describing the spatial distribution of potential and
substrate in the biofilm. The model is simulated in computer using numerical methods. Results show
this model to be in concordance with reported works, but additionally it is highlighted the importance
of the biofilm growth dynamics as controlling factor.
