Mathematical analysis on a droop model with intraguild predation

In this paper, we analyze a predator-prey chemostat system with internal storage, in which the predator not only competes for a single inorganic nutrient with the prey species but also consumes the prey for growth. The outcome for the corresponding model without intraguild predation is that the competitive exclusion holds, that is, the superior species will win the competition, and coexistence will not happen. When the mechanism of intraguild predation is added into the system, our analysis indicates that coexistence can be possible.
