Simulation results of bacterial growth in arrangements with varying the densely packed pillar region sizes and densities. (A) Definition of the distance between pillars (d) and the size of the densely packed pillar region (n). (B) Examples of arrangements with varying n (d = 3) at t = 150. (C) Boxplot of bacterial pixel counts for each arrangement with varying n (d = 3) and fractal arrangement at t = 150. (D) Examples of arrangements with varying d (n = 3) at t = 150. (E) Boxplot of bacterial pixel counts for each arrangement with varying d (n = 3) at t = 150. Results are based on 100 simulation runs. Statistical significance of the Wilcoxon rank-sum test is indicated by asterisks: *P < 0.05, **P < 0.01.
