Figure 1. The growth inhibition of Acinetobacter baumannii exposed to silver acetate is concentration dependent.

Silver acetate was added to exponentially growing cultures at final concentrations of (A) 0.98, (B) 1.95, (C) 3.91, (D) 7.81 and (E) 15.60 mg L⁻¹. Cultures were incubated at 37 °C with shaking and growth monitored via absorbance (OD₆₀₀) every 20 min for 24 h. (F) Panel shows growth in the presence of all concentrations of silver acetate for comparison. N = 3, error bars are omitted for clarity, but standard deviations were all within the range 0.0006–0.1664.
