  1. Mean values (n = 3 [±SD]). DOX = doxycycline; ΔOD = Maximum minus minimum optical density reading at 600 nm; Lag phase = Length of time culture remains at <-10% of maximum OD; T½Max = time taken to achieve half maximal culture growth (maximum OD minus minimum OD × 0.5); DTmin = fastest observed doubling time.
