A Mathematical Model of Competition for Two Essential Resources in the Unstirred Chemostat

Abstract

A mathematical model of competition between two species for two growth-limiting, essential (complementary) resources in the unstirred chemostat is considered. The existence of a positive steady-state solution and some of its properties are established analytically. Techniques include the maximum principle, the fixed point index, and numerical simulations. The simulations also seem to indicate that there are regions in parameter space for which …
