(c) Heat-map (right) of the ratio of x1 to x2 at 72 hr across a broad range of growth rate parameter values (μ1 and μ2). Initial conditions for simulations were x1o = 0.0008, x2o = 0.0158. The line (white) outlines the parameter regimes for coexistence and single-species dominance at steady-state. The circle (black) represents the inferred parameter values for the CH, ER consortium.
