Biological denitrification among various denitrification methods is the most widely accepted process because of its economical and environmental advantages. And bioelectrode has been studied. The bioelectrodes have some troubles–electron transfer, cost, and durability. In this study, Ochrobactrum anthropi SY509 was used as biocatalyst and the novel bioelectrode was made of silicone and graphite mixture. And in the bioelectrode, the electrons were t ransferred directly to the immobilized biocatalyst. And the graphite powder was coated by biocatalyst for increasing the electron transfer efficiency. Using this electrode, high denitrification efficiency and durability was obtained.
