FIG. 3.

The effect of AgNO₃ on the growth and viability of S. aureus. S. aureus cultures were set up, at an initial inoculation density of 5 × 10⁷ CFU ml⁻¹, in nutrient broth containing different concentrations of AgNO₃. Cultures were incubated for 20 h, after which they were sampled for viable counting. Error bars represent ±1 standard deviation.
