After
5.4 ppm s ozone dose, lag-phases were longer for injured cells recovered at 10 1C than 37 1C. Furthermore, treated cells recovered in
nutrient broth at 10 1C were unable to grow after 16.5 ppm s ozone dose. Finally, after 5 min, S. sonnei counts were reduced by 0.9 and 1.4
log units in those shredded lettuce samples washed with 2 ppm of ozonated water with or without UV-C activation, respectively.
