“…Besides, the electrogenesis mechanism is speculated to be the reversed methanogenesis with electrons deposited on the anodes by methanotrophs in combination with electron production by exoelectrogens (e.g., Geobacter and Desulfovibrio ) that degrade the AOM intermediates. This is analogous to the bacterial syntrophic electrogenic behaviors observed previously among pure cocultures. , Therefore, the syntrophic interaction between certain archaea and bacteria can be designed as an alternative electrogenic strategy in future MFCs. Such synergistic biocatalysts will expand the biodegradable substrate types of MFCs.…”

“…A wide variety of dissolved substrates, ranging from macromolecular carbohydrates (starch, lignose, etc.) to simple compounds (e.g., acetate and formate), have been utilized for electricity generation in MFCs. − However, MFCs powered by gaseous substrates, such as methane and hydrogen, have emerged only in recent years and remained largely unexplored.…”

Microbial fuel cells (MFCs) are a promising technology that converts chemical energy into electricity. However, up to now only few MFCs have been powered by gas fuels, such as methane, and their limited performance is still challenged by the low solubility and bioavailability of gases. Here, we developed a gas diffusion cloth (GDC) anode to significantly enhance the performance of methane-powered MFCs. The GDC anode was constructed by simply coating waterproof GORE-TEX cloth with conductive carbon cloth in one step. After biofilm enrichment, the GDC anodes obtained a methane-dependent current up to 1130.2 mA m −2 , which was 165.2 times higher than conventional carbon cloth (CC) anodes. Moreover, MFCs equipped with GDC anodes generated a maximum power density of 419.5 mW m −2 . Illumina high-throughput sequencing revealed that the GDC anode biofilm was dominated mainly by Geobacter, in contrast with the most abundant Methanobacterium in planktonic cells. It is hypothesized that Methanobacterium reversed the methanogenesis process by transferring electrons to the anodes, and Geobacter generated electricity via the intermediates (e.g., acetate) of anaerobic methane oxidation. Overall, this work provides an effective route in preparing facile and cost-effective anodes for high-performance methane MFCs.

“…In separate fermentation (first by Streptococcus bovis 148 followed by Shewanella oneidensis MR-1), a Pdm of 49.9mW m -2 , and CE of 10.2% were obtained. In parallel fermentation (using both bacteria at the same time), a Pdm of 12.1mW m -2 and CE of 4.7% were obtained [117]. The results indicated that two-stage fermentation has a higher performance in comparison with parallel fermentation in one stage.…”

Today, the world is facing climate change challenges with environmental protection being a top priority. Optimizing energy consumption due to its high cost and environment protection is a basic human demand. For industries, reduction in production costs is determinative to success. In this regard, Microbial fuel cell (MFC) is a unique promising technology with wastewater treatment and bioelectricity generation. The MFCs will help reduce energy consumption, curb the wastewater pollution, and standardize it for releasing into the environment. The food industry by producing high volumes of biomass with high organic pollution load are highly prone to use in MFCs as a substrate. Various food industry effluents have been tested, in real or synthetic form in the MFCs. Due to the improvements in the process and progress in novel configurations, better results have been increasingly obtained. Now, the MFC can be used in the industries individually or by integration with other technologies. In this review, the latest results from the use of food industry wastewater in MFCs along with effective process conditions are evaluated.
