Figure 9. Comparison of CPO residual activities during 4 hrs using direct addition (DA by single and 5X pulsed additions, bioelectrochemical (EG) process with continuous aeration (EG -620mV_SCE) and controls with only CPO. Reaction mixtures contained 6.0 UI/mL CPO, 0.5 mM CP, 1.0 mM peroxide concentration for DA in 100 mM sodium-potassium phosphate buffer pH 6.0 at 25ºC and 200 rpm.
