L. acidophilus cell inactivation. Cell inactivation (log reduction CFU mL−1) (ac) and LC50 values (d) for L. acidophilus exposed to a 600-ns PEF (blue) or its respective TE (red) at an amplitude of 13.5, 18.5 or 23.5 kV cm−1 and 1, 5, 10, 100 or 1000 pulses. nsPEF and TE results are normalized to the sham and are the mean plus SE of three independent experiments (n = 3). LC50 values were calculated by utilizing the mean log reduction CFU mL−1 at each amplitude. An asterisk represents a statistically significant difference (p ≤ 0.05) between the nsPEF and TE exposure for that pulse number
