Abstract
Bioelectrochemical Systems (BES) for use as Biological Oxygen Demand (BOD) sensors, systems incorporating BES sensors for measuring BOD, and methods of using the sensors and systems for measuring BOD. The disclosed sensors are inexpensive to construct, long-lasting, have a fast response, and a large dynamic range. The invention includes biological oxygen demand (BOD) sensors which incorporate at least three working electrodes, at least one counter electrode, a reservoir for dilution fluid, and a sensor for measuring an electric current or a voltage which flows from the working electrodes to the counter electrode. The BOD sensors will typically also include at least one electrically active microbe disposed in proximity to the working electrode.
