“…Using ADW, we were able to compare results of the present study with those obtained in the previous studies. We found that, in the absence of PIS, ADW-MFC exhibited a similar level of P max (179 ± 5 mW m À2 ) to those reported in the previous studies (Miyahara et al, 2013;Yoshizawa et al, 2014;Miyahara et al, 2015b). It is also shown that the addition of PIS (D-P MFC) substantially increased P max (301 ± 1 mW m À2 ; over 50% increase).…”

“…The putative electrogens, found in both the acetate and wastewater fed reactors form a larger group, but the largest group by far is the group of organisms found exclusively in the acetate reactors. Of the ten most dominant species found in both reactors, all have previously been observed in MFC reactors [42][43][44]. Those which dominate within the wastewater fed and within the acetate fed reactors only are mostly Proteobacteria, of the Beta, Gamma and Alpha classes, which are largely facultative or obligate anaerobes.…”

The factors that affect microbial community assembly and its effects on the performance of bioelectrochemical systems are poorly understood. Sixteen microbial fuel cell (MFC) reactors were set up to test the importance of inoculum, temperature and substrate: Arctic soil versus wastewater as inoculum; warm (26.5°C) versus cold (7.5°C) temperature; and acetate versus wastewater as substrate. Substrate was the dominant factor in determining performance and diversity: unexpectedly the simple electrogenic substrate delivered a higher diversity than a complex wastewater. Furthermore, in acetate fed reactors, diversity did not correlate with performance, yet in wastewater fed ones it did, with greater diversity sustaining higher power densities and coulombic efficiencies. Temperature had only a minor effect on power density, (Q 10 : 2 and 1.2 for acetate and wastewater respectively): this is surprising given the well-known temperature sensitivity of anaerobic bioreactors. Reactors were able to operate at low temperature with real wastewater without the need for specialised inocula; it is speculated that MFC biofilms may have a self-heating effect. Importantly, the warm acetate fed reactors in this study did not act as direct model for cold wastewater fed systems. Application of this technology will encompass use of real wastewater at ambient temperatures.

“…In another report, an NWCF electrode for MFCs interposed between iron nets showed 1.5 times higher power density compared with that for MFCs without the iron nets [25]. In another report, NWCFs were used in a type of MFCs called a Slalom-flow cassette-electrode microbial fuel cell [26]. As mentioned above, the development of an NWCF coated with ferric oxide is important to improve the current density.…”

Iron particles were immobilized onto non-woven carbon fiber via electroplating for use in a microbial fuel cell (MFC). Electroplating was performed under an applied voltage at a current of 0.2 A for 5, 10, and 15 min. The scanning electron microscope (SEM) observations show that 5 min was not adequate for the particles to be immobilized, whereas 10 and 15 min of electroplating resulted in an adequate number of particles on the surface. To evaluate the strength of the binding of iron via electroplating on the surface of the fiber, the samples were washed with pure water and observed using an SEM. The 10 min electroplated sample has a larger surface area, which is suitable for the MFC anode, than the 15 min electroplated sample. According to X-ray photoelectron spectroscopy and X-ray diffraction analysis, the peaks corresponded to those of Fe 2 O 3 , and the sample dipped into tannic acid shows the peaks of Fe 3 O 4 . The amount of biofilm of Shewanella oneidensis MR-1 was evaluated using crystal violet staining, and living bacteria were counted as colony forming units. Electroplated Fe 2 O 3 and Fe 3 O 4 were found to be effective for producing biofilm and immobilizing S. oneidensis MR-1.
