Figure 6.
The absorbance (A490) ofE. coliK12 suspension after 3 h of incubation in LB nutrient medium versus the concentration
of gentamicin (1) and a gentamicin–NP mixture (2). Thex-axis shows twofold dilutions of the preparations. Lines 3 and 4 show the average
absorbance level in the control medium (3) and in a gentamicin-free medium containing
0.1 mM NPs (4)
