Studies on the electrochemical behavior of two products, ammonia and hydrogen, of potentially useful biochemical reactions are reported. The anodic behavior of hydrogen and ammonia under conditions compatible with biological systems are reported. Varioucatalysts were studied and the optimum catalyst and conditions for electro-oxidation compatible with the biological system selected. Polarization characteristics of the B. pasteurii-urea and Cl. butyricum-glucose systems under conditions where the biological phase was physically confined at the electron carrier surface were obtained. Limiting current densities of 3 mAsq cm and open circuit potentials of -0.23 V vs SCE were obtained for the B. pasteurii urea system. The performance of the Cl. butyricum glucose electrode system was inhibited. Evidence is presented to indicate that the inhibition is probably due to carbon black adsorbing the hydrogen produced by the Cl. butyricum.
