Table 1 Bacterial isolates submitted to an O 3 /O 2 gaseous mixture to determine the effect on the in vitro growth of bacteria

From: Effect of low-dose gaseous ozone on pathogenic bacteria

Bacterial strains exposed to 15μg/mL of O3 (in a O3/O2 gaseous mixture – 1%/ 99%) for 5 min Growth at 48 hours (CFU)
P1 P2 P3 P4
