Methanogenesis control by employing various environmental stress conditions in two-chambered microbial fuel cells

Microbial Fuel Cells: Influence of External Resistors on Power, Current and Power Density

“…Similar trends were observed for other days as shown in Figure 3. This is in agreement with previous studies [16][17][18][19][20].…”

Evaluation of electricity production from alkaline pretreated sludge using two-chamber microbial fuel cell

“…The results suggested that there was no obvious correlation between the electricity producing process of alkaline pretreated sludge and methane producing ones. The result is not consistent with previous studies [42,43]. Chae et al [42] suggested that methanogens compete actively with exoelectrogens (electricity-producing bacteria) for their substrate in the anode chamber, causing a significant decrease in the performance of MFCs.…”

“…The result is not consistent with previous studies [42,43]. Chae et al [42] suggested that methanogens compete actively with exoelectrogens (electricity-producing bacteria) for their substrate in the anode chamber, causing a significant decrease in the performance of MFCs. The reason for this phenomenon may be that the sludge organics were plentiful and were converted gradually from insoluble to soluble organics and methanogens and electricity-producing bacteria in the anode chamber were not enough to consume the soluble organics in the test.…”

The effect of real-time external resistance optimization on microbial fuel cell performance

“…There is a significant body of evidence proving that the external resistance at which the MFC operates has an influence on the microbial communities and the long-term performance (Aelterman et al, 2008;Chae et al, 2010;Lyon et al, 2010;Pinto et al, 2010c;Torres et al, 2009). Aelterman et al (2008) observed the impact of R ext on electricity and methane production in an MFC inoculated with a mixed anaerobic culture and concluded that low methane production and stable power output are only obtained if R ext is set close to the MFC internal resistance.…”
