Competition between WT and ΔagrA cells. WT and ΔagrA mutant cells were co-cultivated in ratios 1:1; 1:10; 1:100 or 1:1000 of WT to ΔagrA the presence (TSB+) or absence (TSB−) of glucose for either 30 (grey), 50 (dark grey) or 100 (light grey) generations and the ratio of ΔagrA to WT cells was determined based on agar plates with and without tetracycline compared to the inoculum (black). The bars represent the mean and standard deviation obtained from five independent co-cultures
