Abstract

During the last years the pulsed electric field (PEF) method entered several fields of application. A promising application is the decontamination of hospital wastewater effluents, which are loaded with pathogenic and increasingly with antibiotic-resistant bacteria. For this study, Pseudomonas putida suspended in buffer solution or wastewater from university hospital was used as reference strain. To prove whether the descendent of the survival bacteria develop an adaptation to electric field, surviving PEF treated bacteria were recultivated and pulsed in serial experiments with 10 pulses (100 kV cm
