Quantification of competition outcomes in the colony centre for two initial cell densities (mean inoculum density 1.9 × 105, 106 CFU µl−1). Competitive advantage assesses the fold change in the attacker strain compared with its competitor from the beginning to end of the competition. Competitions where the attacker has just CDI (blue, left), just tailocins (magenta, centre) or both weapons (purple, right) show the advantage gained from using two weapons together as compared to just one. Data are adjusted to account for differences in competitiveness of the strain backgrounds (ΔwapR relative to ΔwbpL; see Methods and Extended Data Fig. 2). Horizontal bars indicate the mean from independent biological replicates, n ≥ 6; see Supplementary Table 5 for exact values of n). Stars above the double weapon data indicate a significant difference between the combination of weapons and either single weapon (blue and magenta), or just CDI (blue) (two-sided Welch’s t-test, P < 0.05, Benjamini–Hochberg correction for multiple testing; see Supplementary Table 5 for exact P values).
