Hydrostatic Pressure and Electroporation Have Increased Bactericidal Efficiency in Combination with Bacteriocins

By N. Kalchayanand, T. Sikes, C. P. Dunne and Bibek Ray


We report here that both ultrahigh hydrostatic pressure (UHP) and electroporation (EP) induced sublethal injury to bacterial cells surviving the treatments. The injured cells of both gram-positive and -negative bacteria became sensitive to the bacteriocins pediocin AcH and nisin. Bacteriocins in combination with either UHP or EP have greater antibacterial effectiveness than UHP or EP alone
