Estimated δ and p values for S. Typhimurium CECT 443 heat-, acid-, alkaline-, and oxidative stress-treated cells^a

Treatment condition	δ (min)	p
Heat (55°C)	0.59 ± 0.20	0.43 ± 0.05
Acid (pH 2.5)	6.72 ± 0.91	0.88 ± 0.08
Alkaline (pH 11.0)	5.18 ± 0.73	0.86 ± 0.07
Oxidation (H2O2 at 40 mM)	11.05 ± 1.06	1.06 ± 0.11

^aδ and p values were estimated from the fit of the mathematical model log N_t/N₀ = −(t/δ)^p to experimental data of S. Typhimurium CECT 443 heat (55°C)-, acid (pH 2.5)-, alkaline (pH 11.0)-, and oxidative stress (H₂O₂ at 40 mM)-treated cells.
