Fitness determination in MIEM and LB growth media. Exponential growth rates were determined by OD600 measurements over time for clones isolated from LL-37, PR-39, and colistin-evolved populations in MIEM (A) or LB (B) media. Relative growth rates were calculated using the parental strain D457 as a reference (dotted line). Error bars represent standard deviation for five independent replicates. Statistical significance relative to D457 was assessed by one-way analysis of variance (ANOVA) test (**, P > 0.0001; *, P > 0.001).
