Bactericidal Effect of Ag Potentiated by Transition Metals. Log change in CFUs/mL with respect to time zero, in Escherichia coli ATCC 11229 after 1 hour treatment with: LB (control), Ag, specific transition metal and their combination. As nominal concentrations: (A) Ag 30 µM, Ni 0.5 mM and the combination; (B) Ag 30 µM, Cd 1 mM and the combination; (C) Ag 15 µM, Cu 1 mM and 2 mM, and the respective combinations; (D) Ag 30 µM, Zn 0.5 mM and the combination. ***Corresponds to a p < 0.05, tested with an ANOVA, that there is a difference with respect to the control and each of the individual treatments. Error bars correspond to the standard deviation from experiments performed in triplicates.
