Bioelectricity production using plant-microbial fuel cell: Present state of art

Abstract

Recycling of organic waste is not only vital to emerging countries but developed countries too. Presently, a worldwide energy catastrophe is being noticed because of colossal energy requests and constrained capital. Non-sustainable energy sources are draining, and sustainable energy sources are not appropriately being used. There is a prompt backup course of action quest for energy generation. Microbial fuel cells (MFC) innovation, which utilizes micro-organisms to convert the synthetic energy of organic compounds into power, is viewed as a potential alternative option. A promising adaptation of MFC is a plant microbial fuel cell (P-MFC) that implements adistinctive plant-microorganism rhizospheric relationship to transform solar energy into bioelectricity. P-MFC technology is a holistic approach involving various interrelated fields. The system comprises of two structure types; biocontrol and bioprocess structures. Up to 70% of organic matter produced by plants during photosynthesis winds up in the soil as dead root material. The micro-organisms on and around the surface of the roots oxidize these carbon-based exudates, discharge CO2, protons, and electrons. The rhizodeposition at the soil alliance combined with productive designing drives this rhizospheric relationship and eventually contributes towards genuine applications. Thus, this review emphasizes majorly on three criteria; Components and building viewpoints engaged with structuring an effective setup, the efficiency of P-MFC in power generation, and lastly the sustainability of P-MFC.
