Growth phase dependence of the fraction of persisters to gentamicin, ofloxacin, or ampicillin. Temporal dependence of the normalized fraction of persisters to treatment either with gentamicin (A), ofloxacin (C), or ampicillin (E), with the addition of fresh LB, or with antibiotics only [(B,D,F), respectively]. At t = 0 an overnight E. coli culture was diluted 1:1000 in LB medium and the culture growth started. Each data set is normalized to its maximum persister fraction. Data and error bars are the mean and SEM of measurements obtained at least on biological and technical triplicates.
