title: [Effect of high hydrostatic pressure on microbial physiological characteristics].
abstract: Physiological characterizations of Listeria monocytogenes NCTC 11994 and Escherichia coli ATCC 80739 have deeply changed by high hydrostatic pressure. The results showed that counts of both microbial strains decreased 7 log cfu at 400MPa, 10 min. Pressure treatments also resulted in change of Intracellular pH value, lowed membrane potential, have internal potassium filtered out, and decreased ATP concentration.
