E. coli O157:H7 cells exposed to different pHs (3.6, 5.2, and 7.0 for 6 h), different temperatures (4, 35, and 40degreesC for 6 h), and different pre-PEF treatments (10, 15, and 20 kV/cm) were treated with PEFs (20, 25, and 30 kV/cm) or heat (60degreesC for 3 min). The results of these experiments demonstrated that a pH of 3.6 and temperatures of 4 and 40degreesC caused significant decreases in the inactivation of E. coli O157:H7 by PEF treatment and heat treatment (P < 0.05). Pre-PEF treatments, pHs of 5.2 and 7.0, and a temperature of 35degreesC, on the other hand,did not result in any resistance of E. coli O157:H7 cells to inactivation by PEF treatment and heat treatment (P > 0.05).eninfo:eu-repo/semantics/openAccessListeria-MonocytogenesAcid AdaptationSalmonella-TyphimuriumEnvironmental StressesGrowth AtmosphereCross-ProtectionResistanceShockToleranceSurvivalArticle66575575910.4315/0362-028X-66.5.755127476812-s2.0-0038404939Q2WOS:000182669900005Q1
