Abstract: A sediment microbial fuel cell is provided. More specifically, the present invention provides a sediment microbial fuel cell characterized by comprising: an oxide electrode unit located within the sediment of polluted water; a reduction electrode unit located adjacent to the water surface within the water; and a solid matter separator unit arranged inside the sediment and located in an upper part of the oxide electrode unit spaced apart from the oxide electrode unit, wherein one or more surfaces of the oxide electrode unit are exposed in the separation space formed by the solid matter separator unit.

Abstract: An electrode for an enzymatic biofuel cell may include: a substrate; an electrode positioned on the substrate; and an enzyme pattern containing an enzyme in which a metal-immobilized peptide is expressed positioned on the electrode. The metal-immobilized peptide expressed at the enzyme active site strongly binds to metal deposited electrode surface. In this manner, the enzyme active site facing to electrode was controlled to be in close proximity such that electron transfer efficiency of the electrode can improve.

Abstract: A dissolved carbon monoxide sensor includes an electrode and a carbon monoxide dehydrogenase fixed on the electrode. According to this configuration, the dissolved carbon monoxide sensor directly detects a dissolved carbon monoxide concentration in a solution by an enzyme reaction of the carbon monoxide dehydrogenase.
