Figure 6. Effect of the potential over the bioelectrodegradation of 4-CP. Reaction mixture containing 6 UI/mL CPO, 0.5 mM 4-CP  in 100 mM sodium-potassium phosphate buffer pH 6.0, at 25ºC. EG CC: bioelectrodegradation at the cathodic chamber; EG AC: Anodic oxidation in the anodic chamber; CC C: Cathodic chamber control.
