Filtered wastewater samples were inoculated with Enterococcus faecium and exposed to different pulsed electric field (PEF) treatment energies at 40, 50 and 60 degrees C. A lethal effect of heat treatment on E. faecium can be observed for T > 56 degrees C and a heating duration of 4 min. A treatment with 60 degrees C, 4 min, provokes a bacterial reduction of 4 log. A combined treatment of inoculated wastewater samples with pulsed electric field and heat (40, 50 and 60 degrees C) reduced the bacterial contamination considerably. At a suspension temperature of 60 degrees C pulsed electric field inactivation resulted in a complete bacterial decontamination (8 log reduction rate). Moreover, it was demonstrated that naturally occurring nuclease activities were not changed by the pulsed electric field treatment. In contrast to a thermal treatment with temperature over 72 degrees C, for 4 min., the nuclease activity was reduced up to 90%. In this case, inactivation is only 4 log. The same inactivation rate can be obtained by a combination of heat treatment (60 degrees C) and pulsed electric field treatment (30 J/ml).
