Figure 4. — Spectrophotometric analysis of cadmium(II) ions treated Staphylococcus aureus. (A) Dependencies of growth of bacteria on the applied concentration of cadmium(II) ions (0, 1.25, 2.5, 5, 10, 15, 25 and 50 μg·mL⁻¹) monitored for 24 h. At the beginning of the experiment bacterial culture growing for 24 h was used. From this bacterial culture, starting culture with OD 0.1 (104 cells per mL) was prepared; (B) The growth of cadmium(II) ions treated bacterial cells expressed as OD (absorbance measured at 605 nm) measured at the end of the treatment; in inset: the dependence obtained within the concentration range from 0 to 30 μg of Cd(II) per mL. Growth of the cultures was determined fully automatically for 24 h at 37 °C without shaking of each culture (n = 3).
