Inactivation of Escherichia coli and Listeria innocua in milk by combined treatment with high hydrostatic pressure and the lactoperoxidase system
Article Abstract:
Results demonstrate that milk substrate protects the bacteria against hydrostatic pressure inactivation and reduces the effectiveness of the lactoperoxidase on the viability. Data show that the bacteria exhibit different inactivation kinetics with Escherichia coli showing only a transient decrease under both treatment conditions.

Inactivation of gram-negative bacteria by lysozyme, denatured lysozyme, and lysozyme-derived peptides under high hydrostatic pressure
Article Abstract:
Research on gram-negative bacteria show that enzymatic activity is required for lysozyme's antimicrobial activity. Tests used Escherichia coli, Pseudomonas fluorescens, and two varieties each of Salmonella and Shigella, and involved hen egg-white lysozyme in the presence of high hydrostatic pressure treatment.

Induction of oxidative stress by high hydrostatic pressure in Escherichia coli
Article Abstract:
A demonstration that pressure treatment induces endogenous intracellular oxidative stress in Escherichia coli MG1655 is presented using leaderless alkaline phosphatase as a probe. The results suggested that, at least under some conditions, the inactivation of Escherichia coli by high hydrostatic pressure treatment is the consequence of a suicide mechanism involving the induction of an endogenous oxidative burst.
