| Abstract: | The existence of the positive periodic solution of the chemostat prey model is discussed under certain conditions.By employing the theory of periodic parabolic operators,the Schauder estimate and bifurcation theory,a necessary and sufficient condition for the existence of positive periodic solutions of such model is obtained. |

| Keywords: | Chemostat model bifurcation positive periodic solutions |
