Biodegradation of microplastic in microalgae-based microbial fuel cells (MFC)

Microplastic pollution poses a growing threat to aquatic ecosystems due to its persistence and capacity to accumulate hazardous substances. This study aims to investigate the potential of the marine microalga Chlorella vulgaris integrated within a Microbial Fuel Cell (MFC) system as a biological approach for simultaneous microplastic degradation and bioelectricity generation. Chlorella vulgaris was selected for its adaptability, efficient nutrient uptake, and bioenergy potential. Response Surface Methodology (RSM) was used to optimize growth parameters in wastewater, achieving a biomass yield closely matching predicted values under optimal conditions (pH 7,BBM ratio 0.49).
