An Electricigen Bacteria Biofilm Dynamical Model for Microbial Fuel-Electrolytical Cells Systems

On the basis 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, a mathematical model for anodic electricicigen bacteria useful for Microbial Electrolysis Cells (MEC) and Microbial Fuel Cells (MFC) is suggested. The solution of partial differential equations describing the spatial distribution of potential and substrate in the biofilm is used to implement three major biological reactions. Numerical methods are used to simulate the model in the computer. The results show that this model agrees with previous research, but it also emphasises the significance of biofilm growth dynamics as a controlling factor.
