AN ELECTROCHEMICAL METHOD FOR ENRICHMENT OF MICROORGANISM, ABIOSENSOR FOR ANALYZING ORGANIC SUBSTANCE AND BOD

Disclosed herein is a biosensor that allows an organic substance concentrati on or BOD of a sample to be electrochemically measured in anaerobic condition using a mediator-less biofuel cell. The biosensor utilizes electrochemically active bacteria that were contained in wastewater and sluge and dens...

Beschreibung
Zusammenfassung:	Disclosed herein is a biosensor that allows an organic substance concentrati on or BOD of a sample to be electrochemically measured in anaerobic condition using a mediator-less biofuel cell. The biosensor utilizes electrochemically active bacteria that were contained in wastewater and sluge and densely cultured during the operation procedure of the biofuel cell for the BOD measurement, as a microbial catalyst of the biofuel cell used in the biosensor. As a result, the biosensor can be operated without an artificial addition of microorganisms, and allows the microorganisms to be maintained a t a suitable activity depending on the nature of wastewater. In addition, the biofuel cell used in the biosensor can be operated in a stable manner over s ix months or more.
