Before revision:  Establishing the analogous result for electroactive bacteria has proven challenging. As a first step towards characterizing stability of an electroactive-only equilibrium, we consider local asymptotic stability in a model with three types of microbes, general monotone kinetics, equal removal rates, and a general constraint .
After revision:  Establishing the analogous result for electroactive bacteria is not necessarily true. We show that local asymptotic stability in a model with three types of microbes, general monotone kinetics, equal removal rates, and a general constraint .
