Figure 3.

Flow cytometry analyses of bacterial strains after contact with 5Lys. The bacteria were incubated in a solution of 5Lys (1 μM) for 30 min at 37 °C, then washed with saline. PI was added (0.01 mg/mL) in order to appreciate the bacterial viability. Q1 refers to bacteria with permeable membrane (PI positive). Q2 refers to double positive bacteria (PI positive and PS positive). Q3 and Q4 refers to live bacteria (PI negative) of which Q4 are labeled with PS. Based on three independent experiments, the average population repartition is specified for each condition.
