Microbial Biofuel Cell: Harnessing Bioelectricity from Fisheries Wastewater Using Saccharomyces cerevisiae

Microbial fuel cell (MFC) technology offers an innovative and sustainable solution for energy production, particularly in electricity-deprived regions. The MFC system harnesses electrons released during biochemical reactions catalyzed by microorganisms. This study focuses on the design of a microbial biofuel cell that utilizes S. cerevisiae to generate bioelectricity from fisheries wastewater. Optimization of physical parameters was performed to maximize bioelectricity generation from fisheries wastewater. The results revealed that S. cerevisiae-based MFC achieved the highest bioelectricity production at 35 ºC, pH 8, and an incubation period of 72 hours. To enhance performance, a flow rate of 50 mL/min of oxygen in the wastewater was found to be the most effective for bioelectricity generation. The findings demonstrate the practicality and sustainability of the S. cerevisiae-based MFC as a viable technique for both bioelectricity production and wastewater management in the fisheries industry. This innovative approach not only addresses the basic electricity needs of electricity-deprived regions but also helps mitigate wastewater pollution, presenting an environmentally friendly solution. The study highlights the potential of MFC technology to contribute to renewable energy generation and environmental sustainability in regions reliant on fisheries wastewater.
