Abstract
In this paper, a mathematical model for the lactic acid fermentation in membrane bioreactor is investigated. Using the Floquet’s theorem and small amplitude perturbation method, we obtain the biomass-free periodic solution is locally stable if some conditions are satisfied. The permanent conditions of the system are also given. Furthermore, in a certain limiting case it is shown that a nontrivial periodic solution emerges via a supercritical bifurcation. Finally, our findings are confirmed by means of numerical simulations.
