Coexistence in a chemostat: Application of a threshold policy
A well known result in chemostat theory states that two populations of microorganisms which compete for a single limiting nutrient cannot coexist under the condition of a spatially uniform environment and time invariant external influences. In this same setting, altering the dilution rate by means of a threshold policy can revert competitive exclusion to species coexistence in a vicinity of a previously chosen concentration.
