| Outline of Final Research Achievements |
In this study, we aimed to improve the activities of bacterial nitrification and denitrification by an electrode potential. Denitrification activity was increased by applying a potential of -0.2 V (vs. Ag/AgCl reference electrode) to the electrode. And also nitrification activity was increased by applying a potential of +0.57 V to the electrode. Electrode modification with 1-aminoanthraquinone further improved the activity of denitrification. This electrochemical metabolic control method was also effective in pure cultures and environmental microflora.
