Fig 4. The effect of efflux rate, decay rate, and diffusion rate on the MSC.

Fig 4

At low diffusion rates (upper row), efflux rate limits the success, while at large diffusion rate (bottom row), colony size is the more limiting factor. From left to right (a→b, c→d) extracellular decay rate increases (φ = 0.7 and 0.9). From the top to the bottom (a→c, and b→d), diffusion rate increases (D = 0.5 and 12), respectively. Model parameters are: rB,0 = 0.8, rP,0 = 0.8, c = 0.1, ρB,0 = 1, αB = 0.6, αP = 0.6, βP = 0, γB = 0.3, γP = 0.3, a = 1, T = 1, k = 25, N = 10 000, nB,0 = 100, nP,t = 10, κ = 300, f = 0.01, Δt = 1/10, u = 100, ε = 0.01, r+ = 0, s+ = 0, ρ+ = 0, and τ = 0.
