Generation times were calculated from the growth curves in Additional file 2: Figure S2. Values are given as mean ± SD (n = 3). Data were analyzed using Student’s t-test. **P-values ≤0.001 comparing mean generation time of PM2405 or PM2405A with mean generation time of BW25113 was considered statistically significant
