“…4,79 The genus Sphaerochaeta was detected in microbial electrolizer cells. 33,80 The action of Sphaerochaeta may be consistent with the probable generation of H 2 in the methanogenesis carried out by the Archaea domain. On the other hand, the genus Propionicimonas is believed to take part in mediated transfer through the production of phenazines or other soluble electron shuttles susceptible to use in other metabolic pathways.…”

“…Among the Bacteria selected, despite being typically a marine microorganism that grows by oxidizing acetate under anaerobic conditions, Desulfuromonas acetoxidans are known to be susceptible to producing electrogenic activity and, thus, it has been proved to be able to carry out electron transfer to the electrode , . The genus Sphaerochaeta was detected in microbial electrolizer cells , . The action of Sphaerochaeta may be consistent with the probable generation of H 2 in the methanogenesis carried out by the Archaea domain.…”

“…On the other hand, the production of electricity should be mainly related to bacteria population. The energy recovery is mainly associated with Shewanella and Geobacter in the literature . The presence of Geobacter is negligible, while the presence of Shewanella increases with the sludge age, opposite to the direction in which the production of electricity increases (it can be related to its slow growth).…”

But despite the presence of Shewanella and other known electrogenic genera such as Pseudomonas and Arcobacter, 36,42,78 there was only a small fraction of microorganisms whose abundance varies in a similar fashion and also follows the same trend as the generation of electricity.…”

BACKGROUND This work is focused on the assessment of the performance of mini‐scale air‐breathing microbial fuel cells (MFCs), by monitoring the evolution of the bio‐electrogenic activity for a period of 40 days and by comparing the microorganisms populations developed in each of the MFCs after this period. RESULTS Five MFCs were operated at sludge ages ranging from 1.4 to 10.0 days. Results showed the superb performance of the MFC operating under a sludge age of 2.5 days. Desulfuromonas, Syntrophothermus, Solitalea, Acholeplasma, Propionicimonas, Desulfobacula and Sphaerochaeta are proposed as potentially responsible for the bio‐electrogenic activity. CONCLUSIONS Microbial population analysis through Illumina amplicon sequencing demonstrated that despite all MFCs being seeded with the same mixed culture inoculum, the biological cultures developed in the suspension and the biofilm are completely different and depend strongly on sludge age. © 2017 Society of Chemical Industry

In bioelectrochemical systems (BES), the catalytic activity of anaerobic microorganisms generates electrons at the anode which can be used, for example, for the production of electricity or chemical compounds. BES can be used for various purposes, including wastewater treatment, production of electricity, fuels and chemicals, biosensors, bioremediation, and desalination. Electrochemically active microorganisms are widely present in the environment and they can be found, in sediment, soil, compost, wastewaters and their treatment plants. Exoelectrogens are microorganisms capable of donating electrons to anode electrode or accepting electrons from cathode electrode and are mainly responsible for current generation or use in BES. However, current generation from fermentable substrates often requires the presence of electrochemically inactive microorganisms that break down complex substrates into metabolites which can be further utilized by exoelectrogens. The growth and electron transfer efficiency of anaerobes depend on several parameters, such as system architecture, electrode material and porosity, electrode potential and external resistance, pH, temperature, substrate concentration, organic loading rate, and ionic strength. In this chapter, the principles and microbiology of bioelectrochemical systems as well as selective factors for exoelectrogens are reviewed. The anaerobic microorganisms and their electron transfer mechanisms at the anode and cathode are described and future aspects are briefly discussed.
