From: Lytic Escherichia phage OSYSP acts additively and synergistically with gaseous ozone against Escherichia coli O157:H7 on spinach leaves

Figure 4

Changes in Escherichia phage OSYSP titer (log PFU g−1) on spinach leaves when gaseous ozone was applied at different phases of phage application: Ozone applied immediately after bacteriophage spray (0 h, wet phage inoculum) or 1 h after phage spray (dry phage inoculum). Average log reductions were obtained from at least 3 independent treatments. Different letters on bars represent significant difference (P < 0.05). Error bar indicates ± standard error of the mean.
