Modelling gene-dependent PEF resistance of E. coli K-12.

Food microbiology - 1 Aug 2026

Abstract excerpt

The current study investigated the antimicrobial mechanisms of Pulsed Electric Fields (PEF) by evaluating the resistance of 22 Escherichia coli K12 mutants. Initial screening at PEF treatment (23 kV/cm, 53.3 μs, 95.4 kJ/kg), pH 7.0, revealed increased sensitivity (p < 0.05) of ΔclpB, ΔrpoS, and ΔdnaK expressed in Log10 reductions. Further inactivation kinetic analysis of 8 selected strains at pH 7.0 and 4.0...
