Inhibitory Effect of the MIC dilutions of Ag potentiated by transition metals against Bacillus subtilis. Inhibitory percentage by sub-inhibitory combinations of Ag-transition metals in Bacillus subtilis ATCC 23857. Experiments with combinatorial treatments of Ag with (A) Ni, (B) Cu, (C) Zn and (D) Co. Each combinatorial treatment with inhibition >80% is significantly different to the effects of the individual treatments. Each checkerboard treatment was done in triplicates.
