FIG. 4.

Kinetics of inactivation of L. plantarum TMW1.460 incubated at 200 (A) (n = 4), 400 (B) (n = 3), 500 (C) (n = 3), and 600 (D) (n = 2) MPa. Shown is the viable cell count on MRS (nonselective agar) (●) and MRS-NaCl (selective agar) (○) compared to that of untreated cultures. The cell count of control cultures was (4.27 ± 2.09) × 10⁸ CFU ml⁻¹ on either agar, and the detection limit was 120 CFU ml⁻¹. Symbols represent means ± standard deviations of n independent experiments.
