Fig. 5From: Low concentrations of acetic and formic acids enhance the inactivation of Staphylococcus aureus and Pseudomonas aeruginosa with pulsed electric fieldsThe comparison of bacteria inactivation induced by the most effective protocols that were proposed in the study. The asterisk (*) represents statistically significant difference (P < 0.05) between S. aureus and P. aeruginosa. The asterisk (**) represents statistically significant difference (P < 0.05) between 25 and 30 kVcm− 1 procedures, which indicates that the effect is not saturated and can be enhancedBack to article page
