Fig 4. Time-kill curve and effect of EDTA on the antibacterial activity of PlyE146.

Fig 4

For the time-kill experiments (A), logarithmic-phase growing E. coli K12 cells were exposed to PlyE146 (400 μg/mL) in NaPi buffer (pH, 6.0) for 4 h at 37°C. For EDTA experiments (B), logarithmic- and stationary-phase growing E. coli K12 cells were exposed to PlyE146 (400 μg/mL) in the absence or the presence of EDTA (5 mM) in NaPi buffer (pH, 6.0) for 2 h at 37°C. Results represent the mean ± standard deviation of triplicate experiments.
