Extinction and Permanence of Two-nutrient and One-microorganism Chemostat Model with Pulsed Input in a Polluted Environment

摘要

In this paper,chemostat model with pulsed input in a polluted environment is considered.By using the Floquet theorem,we find the microorganism-eradication periodic solution is globally asymptotically stable if the impulsive period T is more than a critical value.We can also find the nutrients and microorganism are permanent if the impulsive period T is less than the critical value.
