“…[58] Proteobacteria are the dominant microorganisms in anode-associated community of MFCs. [51,65,66] Futamata et al [67] reported that Propionibacterium and Clostridium were the predominant bacteria in two-chamber MFC inoculated by soil. However, they showed that some predominant bacteria closely related to Pseudomonas strains were detected during the first week of inoculation, suggesting that these bacteria played as oxygen scavengers.…”

“…However, they showed that some predominant bacteria closely related to Pseudomonas strains were detected during the first week of inoculation, suggesting that these bacteria played as oxygen scavengers. [67] Rumen microorganism was used as inoculums for electricity generation from cellulose by Rismani-yazdi et al [65] In their study, the major bacteria in the anode-attached biofilm were related to Clostridium and Sedimentibacter, with sequences similar to Desulfotomaculum and Ruminococcus, while Comamonas were plentiful in the suspended consortia. [65] Chen et al [51] concluded that Ochrobactrum intermedium, Delftia acidovorans and Citrobacter freundii may be new bioelectricity-producing species which are from the proteobacteia phylogeny.…”

“…[25] In some cases, pure substrates such as glucose, [33,59,70] acetate, [60,62,71,72] butyrate, [72] lactate, [67] proteins, cellulose, [50,65,[73][74][75] cysteine, [76] glycine [51] and glycerol [51] have been used. Acetate is a nonfermentable substrate and a suitable electron donor for dissimilatory iron-reducing bacteria which generate power up to 66% higher than butyrate.…”

Microbial fuel cell (MFC) is a novel technology that can be used for electricity generation during oxidization of the organic substances presented in the substrate. To obtain a desirable performance, it is essential to understand the influential factors on the MFC. Among the numerous factors affecting the MFC performance, substrate, microorganisms and their metabolism, electron transfer mechanism in an anodic chamber, electrodes material and the shape of electrodes, type of membrane, operating conditions such as temperature, pH and salinity, electron acceptor in a cathodic chamber and geometric design of the MFC are considered as the most important factors. Among different substrates, wastewater is a sustainable rich medium which can be treated by MFCs. There are various types of exoelectrogenic bacteria presented in wastewaters which can oxidize organic matter and transfer electrons to the anode without using mediators. Like other microbial systems, optimum pH and temperature enhance the bacterial growth which can improve the MFC performance. Despite the negative effect of salt on microbial growth, higher salinity and ionic strength can increase the conductivity of substrate and therefore enhance MFC performance. Scaling up MFC is a controversial issue which needs a comprehensive understanding of these factors. By using new inexpensive materials for electrodes and membrane for manufacturing MFCs, a more cost-effective design for scalable wastewater treatment and high power generation can be achieved. Furthermore, MFC is a suitable candidate for bioremediation of contaminated groundwater. These factors and their impact on the MFC performance have been reviewed in the present survey.

“…Exoelectrogenic microorganisms are naturally found in anaerobic environments such as aquatic sediments (Tender et al, 2002;Holmes et al, 2004), soils (Niessen et al, 2006;Futamata et al, 2013), and sludge from waste treatment plants (Kim et al, 2004). Preferably, they develop adhered to the surface of the electrodes in the form of biofilms and are able to use diverse anaerobic metabolic pathways to oxidize the carbon sources (Venkata Mohan et al, 2014).…”

-Microbial fuel cells (MFC) are electrochemical devices that utilize the ability of some microorganisms to oxidize organic matter and transfer electrons resulting from their metabolism to an insoluble acceptor. The goal of the present study was to model the kinetics of electrical current generation from an MFC inoculated with marine sediment. For this purpose, a differential equation system was used, including the Nernst-Monod relationship and Ohm's Law, to describe the microbial metabolism and the mechanism of extracellular electron transfer (EET), respectively. The experimental data obtained by cyclic voltammetry analysis were properly described by the model. It was concluded that marine microorganisms preferably use a direct mechanism of EET by means of nanowires to establish the electrochemical contact with the anode. The mathematical modeling could help understand MFC operation and, consequently, contribute to improving power generation from this source.

This study builds on the previous work of urine utilisation and uses small-scale microbial fuel cells (MFCs), working both as individual units in cascade or collectively as a stack, to utilise artificial urine. Artificial urine was prepared at concentrations typically found in real human urine with peptone employed as a surrogate proteinacious component. MFCs were constructed from Nanocure® polymer using rapid prototype technology. The anode and cathode electrodes were made of 15 cm2 carbon veil, folded down to fit in the 1 mL chambers. Eight MFCs were inoculated using activated anaerobic sludge; after 17 days of fed batch mode they were switched to continuous flow, initially at 0.09 mL/h and subsequently at 0.43 mL/h, resulting in HRT of 12.69 minutes/MFC. MFCs showed stable performance following the maturing period and produced, under polarisation experiments, peak power levels of 117 μW, corresponding to 962.94 W/m3. Continuous flow experiments data showed higher power production, increasing with the concentration of the carbon/energy source within artificial urine. The work demonstrates that artificial urine of varying composition can be successfully utilised for the production of energy and concomitant cleanup of organic waste. Finally, in line with the practical implementation and robotics work in our group, the small-scale MFCs were configured into a stack and directly energised electronic devices.
