Abstract:

The chemostat is an ideal laboratory apparatus in which to study the dynamics of microorganisms. It can be thought of as a model for an ecosystem influenced by naturally varying or intentionally designed interactions. This tool is of principal importance in microbiology and population biology in terms of its applications. We will study models describing the competition in the chemostat between two species for a single growth-limiting resource and two species for two resources. The uptake functions are Michaelis-Menten. We will discuss the Competitive Exclusion Principle also referred to as Gause's Law, a central result in the theory of ecological competition. It states that only one competitor survives when two or more species compete for a single growth-limiting resource.
