Electricity production in biofuel cell using modified graphite electrode with Neutral Red

E. coliwas used as a biocatalyst to compare electricity production, substrate consumption and growth in biofuel cells. With the native electrode 1.44 mV cm−2-electrode and 1.41 μA cm−2-electrode electricity were produced and 21 mM acetate was consumed. With the modified electrode with Neutral Red, 3.12 mV cm−2-electrode and 3.1 μA cm−2-electrode electricity were produced and 39 mM acetate was consumed.
