an inexpensive glucose biosensor based on a mixed culture microbial fuel cell (mfc) for bod monitoring applications

Microbial fuel cells (mfcs) are used for including electricity generation, wastewater treatment, and also biosensors. the purpose of the current research is to study an mfc as a biosensor to measure glucose as a biological oxygen demand (bod) indicator. results showed that there is a very good linear relationship by plotting open circuit potential (ocp), maximum power, and short circuit current of the mfc vs. glucose concentration in the 0.1-5 g/l range. so the developed biosensor can be scaled and used as a promising cost-effective glucose biosensor and/or bod monitoring sensor in food industry-related applications.
