“…3 ). In addition to Geobacter , 10 other genera that include known electrogenic bacteria species were detected among the top 100 genera in all CW mesocosm samples, including Geothrix , Desulfobulbus , Desulfovibrio , Pseudomonas , Clostridium ( 2 ), Desulfotomaculum ( 36 ), Enterobacter ( 37 ), Bacillus , Rhizomicrobium ( 38 ), and Anaeromyxobacter ( 32 ). Most of the aforementioned electrogenic bacteria were more abundant on the electrodes than in the nearby soil samples (paired two-sample t test, P < 0.05) (Table S2).…”

Most studies on electrogenic microorganisms have focused on the most abundant heterotrophs, while other microorganisms also commonly present in electrode microbial communities, such as Actinobacteria strains, have been overlooked. The novel Acidimicrobiaceae sp. strain A6 (Actinobacteria) is an iron-reducing bacterium that can colonize the surface of anodes in sediments and is linked to electrical current production, making it an electrode-reducing bacterium. Furthermore, A6 can carry out anaerobic ammonium oxidation coupled to iron reduction. Therefore, findings from this study open the possibility of using electrodes instead of iron as electron acceptors, as a means to promote A6 to treat NH4+-containing wastewater more efficiently. Altogether, this study expands our knowledge of electrogenic bacteria and opens the possibility of developing Feammox-based technologies coupled to bioelectric systems for the treatment of NH4+ and other contaminants in anoxic systems.

“…Cellulose‐fed MFCs require suitable microorganisms capable of both decomposing cellulose and producing a current. So far, only one microorganism has shown both cellulolytic and electrogenic activity [31,32] . Commonly, to produce electricity by cellulose‐fed MFCs a syntrophic bacteria consortium has to be used: cellulolytic bacteria convert the biomass to chemicals that can be used by exoelectrogenic bacteria.…”

“…Commonly, to produce electricity by cellulose‐fed MFCs a syntrophic bacteria consortium has to be used: cellulolytic bacteria convert the biomass to chemicals that can be used by exoelectrogenic bacteria. The characteristics, operating conditions, and performance, in term of MPD, of some cellulose‐fed MFCs are reported in Table 2 [31–47] . Insoluble cellulose (IC), with few exceptions, [34,35,44] was used as the substrate.…”

“…Thus, as an Pt alternative, in many cellulose‐fed MFCs, due to its good performance, ferricyanide was added to graphite [31,35,37,40,41,44] . Regarding the microorganisms, only two works reported the use of Enterobacter cloacae , the unique microorganism that fulfills the requirements of both cellulose degradation and electricity generation, in cellulose‐fed MFCs [31,32] . Generally mixtures of bacteria are used in cellulose‐fed MFCs.…”

“…representing 73% of the Enterobacteriales order may have important influence on current production, since several species belonging to the Enterobacteriales order have been described as electrochemically active bacteria [50,52e54]. Several authors have reported current generation by species belonging to the Enterobacteriales such as Enterobacter cloacae in a mediatorless microbial fuel cell [55]. Furthermore, Geobacter sp assigned to the Desulfuromonadales order was identified in the biofilm developed on the C-Tex under anode potential control.…”

Anode performance of Microbial Electrolysis Cells (MECs) fed with urine using different anodes, Keynol (phenolic-based), C-Tex (cellulose-based) and PAN (polyacrylonitrile-based) was compared under cell potential control (1st assay) and anode potential control (2nd assay). In both assays, C-Tex MEC outperformed MECs using Keynol and PAN. C-Tex MEC under anode potential control (À0.300 V vs. Ag/AgCl) generated the highest current density (904 mA m À2), which was almost 3-fold higher than the Keynol MEC and 8-fold higher than the PAN MEC. Analysis of anodes textural, chemical and electrochemical characteristics suggest that the higher external surface area of C-Tex enabled higher current density generation compared to Keynol and PAN. Anodes properties did not influence significantly the microbial diversity of the developed biofilm. Nonetheless, C-Tex had higher relative abundance of bacteria belonging to Lactobacillales and Enterobacteriales suggesting its correlation with the higher current generation.
