We have extended the basic chemostat model to allow for selection in the chemostat by inluding mass balances for the biomass of more than one strain. By changing parameters like the different growth rates of the different populations we can optimize the parameters (such as dilution rate and substrate feed concentration) to optimize the selection mechanism. | We have extended the basic chemostat model to allow for selection in the chemostat by inluding mass balances for the biomass of more than one strain.

+ | In this figure we observe three different strains competing in the chemostat. We can observe 3 differnt scenarios. In the first case, Strain 1 has the highest growth rate and as expected after some time reaches the highest biomass in the reactor, allthough the initial concentration is the smallest. | ||
+ | |||
+ | Strain 2 has a higher biomass concentration at the beginning, but due to the slightly smaller growthrate is outgrown by strain 1. | ||
+ | |||
+ | Strain 3 has a growthrate that is smaller than the dilution rate and thus is washed out irrespective of the initial concentration. | ||
