Fig. 4From: Low concentrations of acetic and formic acids enhance the inactivation of Staphylococcus aureus and Pseudomonas aeruginosa with pulsed electric fieldsThe inactivation of bacteria using pulsed electric field treatment combined with acetic acid (0.1%). The treatment was efficient for both bacteria, which was unachievable during separate exposures. The asterisk (*) represents statistically significant difference (P < 0.05) versus control (chemical treatment only)Back to article page
