ZnO Nanoparticles Affect Bacillus subtilis Cell Growth and Biofilm Formation (original) (raw)
Fig 2
Effects of various ZnO-NP concentrations on the growth of Bacillus subtilis.
A. Growth analysis curves were measured by monitoring the optical density (OD) at 600 nm. B. Antibacterial activity of ZnO NPs on B. subtilis cells; ZnO-NP concentrations are shown as -￭-: 0 ppm, -●-:5 ppm -▲-: 10 ppm, -▼-: 25 ppm, -◆-: 50 ppm, -◀-: 100 ppm, and -▶-: 200 ppm.
