| Abstract: | We establish the competitive model of an species microorganisms in a chemostat with a general nutrient uptake function, Models of conpetition with instantaneous and delayed nutrient recycling are considered, we obtain some sufficient condition for the extinction of the species and necessary condition for the persistence of the species. This extends the results of the two papers3] 5]. |
