Time-kill kinetics assessment of best peptide hits. Graphs showing the colony-forming units per mL (CFU/mL; y-axis) of E. coli ATCC 25922 after incubation with peptide 1a (a), 1a-N10 (b), 1a-N9 (c), and 1a-N5 (d) for 0, 0.25, 0.5, 2, 5 and 24 h (x-axis). The peptide concentrations used are indicated by color coding of the respective graphs, while standard deviations are shown by shaded areas. The limit of bacterial detection in this assay was 100 CFU/mL (see Materials and Methods).
