Nernst-ping-pong model for evaluating the effects of the substrate concentration and anode potential on the kinetic characteristics of bioanode

A new kinetic model, the Nernst-ping-pong model, for describing the kinetics of bioanode in a microbial electrolysis cell is developed by considering the intracellular electron transfer mechanisms. This model provides a new insight into the biochemical processes of the bioanode, and for the first time, substrate inhibition of bioanode is well described by this model.
