Due to depletion of coal and other natural fuel there is an urgent need to find eco-friendly and workable technology for alternate energy. Microbial fuel cells is considered as assuringmethod to extract energy from various sources of wastewater and to generate electricity. But, due to practical limits, MFCs are still unsuitable to meet high power demands. Since wastewater contains several contaminants including organic substances, therefore, generation of electric energy from wastewater using MFC can offer an alternate solution for electricity issue as well as to reduce environmental pollution. Microbial fuel cells harvest electrical energy from wastewater with the help of microorganisms present within the wastewater. The energy confined in organic matter converted in to useful electric current. In Microbial Fuel Cell electrons from the microorganisms transfer from a reduced electron donor to an electron acceptor at a higher electrochemical potential. The study highlights that wastewater with high organic content found to be more effective and it also gives good energy production. If the same concept implemented in large scale it can help in achieving sustainable development and it helps in achieving 3R formula in the process of wastewater treatment.

Microbial fuel cell (MFC) is an evolving technology for anaerobic bioenergy generation using electrodes and organic wastewater as a feedstock for catabolic activities of electrogenic bacteria and subsequent electricity generation. The search for suitable inexpensive electrode materials remains the leading interest of researchers in this field. The work here focused on comparative bioelectricity generation from HTC process water (pH = 5.99) and treated–biogas digestate (pH = 7.97) using locally developed corncob pyrochar electrodes and graphite in dual-chambered microbial fuel cells (MFC). The electrodes used in this study were graphite rod (non-porous and very low surface area), KOH–activated corncob pyrochar (KAC) of BET surface area, 1626 m2 g-1 and steam activated corncob pyrochar (SAC) with 485.8 m2 g-1. The highest power outputs achieved were 323.8 µW and 316.8 µW from HTC process water with SAC and KAC electrodes respectively at an external load of 47 Ω. The initial COD (48780 mg L-1), DOC (4000 mg L-1), and TNb (5600 mg L-1) of the biogas digestate decreased significantly to 36405, 3610 and 4300 mg L-1 respectively in the MFC with KOH-activated corncob pyrochar electrodes. The MFC operated with KAC electrode and treated biogas digestate was the most efficient having Coulombic efficiency of 75 % in a comparatively shorter residence time of MFC operation than the MFC with SAC electrode which had a lower Coulombic efficiency of 64 %.

ABSTRACT The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors which support Fe(III) oxide reduction by this organism. Current was produced using a coculture of P. carbinolicus and Geobacter sulfurreducens with ethanol as the fuel. Ethanol consumption was associated with the transitory accumulation of acetate and hydrogen. G. sulfurreducens alone could not metabolize ethanol, suggesting that P. carbinolicus grew in the fuel cell by converting ethanol to hydrogen and acetate, which G. sulfurreducens oxidized with electron transfer to the anode. Up to 83% of the electrons available in ethanol were recovered as electricity and in the metabolic intermediate acetate. Hydrogen consumption by G. sulfurreducens was important for ethanol metabolism by P. carbinolicus. Confocal microscopy and analysis of 16S rRNA genes revealed that half of the cells growing on the anode surface were P. carbinolicus, but there was a nearly equal number of planktonic cells of P. carbinolicus. In contrast, G. sulfurreducens was primarily attached to the anode. P. carbinolicus represents the first Fe(III) oxide-reducing microorganism found to be unable to produce current in a microbial fuel cell, providing the first suggestion that the mechanisms for extracellular electron transfer to Fe(III) oxides and fuel cell anodes may be different.
