Pulsed electric fields cause sublethal injury in Escherichia coli

1 Mar 2003

Abstract excerpt

AIMS: The objective was to investigate the occurrence of sublethal injury in Escherichia coli by pulsed electric fields (PEF) at different pH values. METHODS AND RESULTS: The occurrence of sublethal injury in PEF-treated E. coli cells depended on the pH of the treatment medium. Whereas a slight sublethal injury was detected at pH 7, 99.95% of survivors were injured when cells were treated at pH 4 for 400 micros...
