“…An increase in salt concentration and metabolites as well as cell debris which consequently hampered the microbial activity in these BESs has been reported for these operating temperatures. 23 Until now all studies on MES have been performed at mesophilic conditions 6,9 and an evaluation of the performance of MES for the production of multi-carbon molecules at elevated temperatures and the effect of temperature on rate and efficiency is currently lacking. Production of methane at higher temperatures using electric current has recently been described.…”

BACKGROUND Microbial electrosynthesis (MES), a process by which microorganisms reduce carbon dioxide to multi‐carbon compounds using electrical current as energy source, has so far been demonstrated at temperatures ranging from 25 °C to 37 °C. Elevated operating temperatures, however, could improve overall performance and product recovery. Here the effect of temperature on MES by the acetogenic thermophiles Moorella thermoacetica and Moorella thermoautotrophica is investigated. RESULTS Experiments were performed at operating temperatures ranging from 25 °C to 70 °C to determine the optimum operating temperature for MES. Optimal performance was observed to be close to the optimum growth temperatures reported for these strains. Production rate and activation energy of acetate at 60 °C was 6.9 ± 0.6 mM m−2 d−1 and 45.1 ± 3.8 kJ mol−1 for M. thermoacetica and 11.6 ± 0.9 mM m−2 d−1 and 58.9 ± 2.5 kJ mol−1 for M. thermoautotrophica with columbic efficiencies (CE) of 79 ± 15% and 72 ± 4%, respectively. CONCLUSION Considering CE and acetate production rate during MES, M. thermoautotrophica outperformed M. thermoacetica over a wide range of operating temperatures. Current‐dependent reduction of CO2 also occurred below the minimum growth temperature of these strains, suggesting that MES is non‐growth associated. © 2016 Society of Chemical Industry

“…But researches showed that the thermophilic metabolism has advantages than the mesophilic metabolism. Sarah M. Carver stated the thermophilic condition for wastewater anaerobic digester improved efficiency, and removed many human and animal pathogens (Carvera et al 2011). It seems operation in thermophilic condition may be useful for improvement of effluent quality.…”

Renewable energy will have an important role as a resource of energy in the future. Microbial fuel cell (MFC) is a promising method to obtain electricity from organic matter andwastewater treatment simultaneously. In a pilot study, use of microbial fuel cell for wastewater treatment and electricity generation investigated. The bacteria of ruminant used as inoculums. Synthetic wastewater used at different organic loading rate. Hydraulic retention time was aneffective factor in removal of soluble COD and more than 49% removed. Optimized HRT to achieve the maximum removal efficiency and sustainable operation could be regarded 1.5 and 2.5 hours. Columbic efficiency (CE) affected by organic loading rate (OLR) and by increasing OLR, CE reduced from 71% to 8%. Maximum voltage was 700mV. Since the microbial fuel cell reactor considered as an anaerobic process, it may be an appropriate alternative for wastewater treatment

“…However, a negative point of thermophilic MFCs is higher rates of evaporation than the MFC system itself. Therefore, a continuous mode of MFCs was proposed to allow a replacement of the anolyte and catholyte [79].…”

In this chapter, we focus on microbial fuel cells (MFCs) that convert the energy from organic matters into electrical energy using microorganisms. MFCs are greatly expected to be used as a relatively low-cost and safe device for generating renewable energy using waste biomass as a raw material. At present, however, it has not reached the desired practical application because of the low-power generation; hence, improvements on fuel cell efficiency, such as electrode materials, are still being examined. Here, we focus on the microorganisms that can be used as catalysts and play a central role in improving the efficiency of the fuel cells. Several kinds of microbial catalysts are used in MFCs. For example, Shewanella oneidensis has been well studied, and as known, since S. oneidensis transports the electrons generated within the cell to the surface layer, it does not require a mediator to pass the electrons from the cells to the electrode. Furthermore, Escherichia coli and Saccharomyces cerevisiae, a model organism for MFCs, are also used. The improvements of such microbial catalysts have also been proceeding actively. Here, we elaborated on the principle of MFCs as well as the current situation and latest research on the catalyst development.
