Figure 3.

Current density dependence on applied potential on a Pt electrode recorded at a scan rate of 10 mVs⁻¹. The regions indicate the activation of cathodic and anodic electrochemical reactions in tryptic soy broth (TSB), the medium that is typically used to grow biofilms. (The numbers below the curve in each region represent the region of potential or current density used in the references listed in Table 1.)
