“…Thus, MFCs generate electricity and biofuels from ubiquitous materials while helping to reduce the amount of organic waste that would otherwise pollute the environment, making them highly sustainable. 21 Although such benefits place MFCs as a potential green alternative to traditional fossil fuel-based energy sources, they still face challenges that limit their practical applications, due to the suboptimal components used. 22 Therefore, optimising MFC components is critical to enhancing their performance and therefore feasibility.…”

“…Growing concerns over the depletion of fossil resources and associated environmental problems have motivated the development of sustainable and renewable energy/chemical production using bioelectrochemical systems (BESs) ( Apollon et al, 2022 ). BESs are engineered systems that utilize electrochemical interactions between microbes and electrodes, such as microbial fuel cells (MFCs) ( Miyahara et al, 2013 ) and microbial electrosynthesis systems (MESs) ( Nevin et al, 2010 ).…”

Bioelectrochemical systems (BESs) based on Shewanella oneidensis MR-1 offer great promise for sustainable energy/chemical production, but the low rate of electron generation remains a crucial bottleneck preventing their industrial application. Here, we reconstructed a genome-scale metabolic model of MR-1 to provide a strong theoretical basis for novel BES applications. The model iLJ1162, comprising 1,162 genes, 1,818 metabolites and 2,084 reactions, accurately predicted cellular growth using a variety of substrates with 86.9% agreement with experimental results, which is significantly higher than the previously published models iMR1_799 and iSO783. The simulation of microbial fuel cells indicated that expanding the substrate spectrum of MR-1 to highly reduced feedstocks, such as glucose and glycerol, would be beneficial for electron generation. In addition, 31 metabolic engineering targets were predicted to improve electricity production, three of which have been experimentally demonstrated, while the remainder are potential targets for modification. Two potential electron transfer pathways were identified, which could be new engineering targets for increasing the electricity production capacity of MR-1. Finally, the iLJ1162 model was used to simulate the optimal biosynthetic pathways for six platform chemicals based on the MR-1 chassis in microbial electrosynthesis systems. These results offer guidance for rational design of novel BESs.

Dual functions of activated carbon air‐cathode: Nitrobenzene removal and electricity production in microbial fuel cells

et al. 2022

The removal of nitrobenzene (NB) in microbial electrochemical systems generally requires electrical power to operate systems in the mode of microbial electrolysis cells (MECs). The present study demonstrates that single‐chamber microbial fuel cells (S‐MFCs) assembled with a bioanode and an activated carbon (AC) air cathode could simultaneously remove NB and generate electricity. S‐MFCs with 1 mM NB exhibit long term NB tolerance and stable electricity production, with NB removal up to 98% in an operation cycle and a maximum power of 16.2 ± 1.3 W m−3. High NB loadings significantly inhibited the activity of anodic biofilms, but the inhibition was reversible. Investigating the removal of NB and its reduction product aniline (AN) in different operations supported the fact that the adsorption at the AC air cathode is the main pathway for the removal of NB and AN from solution, except for the partial conversion of NB to AN by anaerobic reduction in solution. In S‐MFCs, the activated carbon in the cathode plays both functions: catalyzing the oxygen reduction reaction and adsorbing NB and AN, so that the S‐MFC assembled with the AC air cathode, unlike most NB removing MECs, functions as a system with both NB removal and electricity production.
