Abstract

Combined photovoltaic module-microbial fuel cell construction shows prospect of advanced autonomous functioning effective energy-production system with the possibility of round-the-clock power generation. Application of Desulfuromonas sp. as anode biocatalyst in photovoltaic (PV) - microbial fuel cell (MFC) could support highly effective eco-friendly energy derivation with simultaneous reduction of organic and inorganic wastes in water environment. D. acetoxidans is exoelectrogenic bacterium that supports S⁰-reduction with H₂S formation and S⁰-oxidation while an electrode serves as the electron acceptor. Simultaneous sulfur redox processes enhance electron transfer to the electrode surface that may increase the effectiveness of microbial fuel cell performance. It was shown that D. acetoxidans IMV B-7384 possesses selective resistance to 0.5-2.5 mM of copper, iron, nickel, manganese and lead ions. Metal-resistant strains of this bacterium may help overcome H2S toxicity, which is produced because of dissimilative S0-reduction, since divalent cations will interact with sulfide ions, forming insoluble precipitates. Thus D. acetoxidans IMV B-7384 may be applied for remediation of toxic metal ions from water environments because of metal fixation in form of insoluble complexes of metal sulfides. D. acetoxidans IMV B-7384 is presumed to have the capability to convert organic compounds, such as malate, pyruvate, succinate and fumarate via reductive stage of tricarboxylic acid cycle. Thus application of effluents as anolyte in MFC, based on D. acetoxidans IMV B-7384, may cause decrease of its organic content with formation of simple benign constituents, such as CO₂ and H₂O. Hence the advanced system for eco-friendly energy generation with simultaneous water pollution control is proposed.
