Azoarcus
''Azoarcus'' is a genus of nitrogen-fixing bacteria. Species in this genus are usually found in contaminated water, as they are involved in the degradation of some contaminants, commonly inhabiting soil. These bacteria have also been found growing in the endophytic compartment (inside the plant between the living cells) of some rice species and other grasses. The genus is within the family '' Zoogloeaceae'' in the ''Rhodocyclales'' of the ''Betaproteobacteria''. Many studies reported this genus about its potential extracellular electron uptake metabolism and has been found in the cathodic part of many microbial fuel cell Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system that generates electric current by diverting electrons produced from the microbial oxidation of reduced compounds (also known as fuel or electron donor) on the anode to oxid ...s, notably in nitrate and oxygen reducing bio-cathodes biofilms.

Rhodocyclales
The ''Rhodocyclales'' are an order of the class ''Betaproteobacteria'' in the phylum "'' Pseudomonadota''".Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. . Following a major reclassification of the class in 2017, the previously monofamilial order was split into three families: *'' Rhodocyclaceae'' ( type family) contains the genera '' Rhodocyclus'' (type genus), '' Azospira'' and '' Propionivibrio''. Cells are curved rods, rings or spirillae. Dominant respiratory quinones are menaquinone-8, ubiquinone-8 and rhodoquinone-8. G+C fractions are 61.6 - 65.3 mol%. *'' Azonexaceae'' contains the genera '' Azonexus'' (type genus), '' Dechloromonas'', '' Ferribacterium'' and '' Quatrionicoccus''. Cells are curved rods or cocci.

Rhodocyclaceae
The ''Rhodocyclaceae'' are a family of gram-negative bacteria.Garrity, George M.; Brenner, Don J.; Krieg, Noel R.; Staley, James T. (eds.) (2005). Bergey's Manual of Systematic Bacteriology, Volume Two: The Proteobacteria, Part C: The Alpha-, Beta-, Delta-, and Epsilonproteobacteria. New York, New York: Springer. . They are given their own order in the beta subgroup of Pseudomonadota, and include many genera previously assigned to the family ''Pseudomonadaceae''. The family was revised in 2017 with the creation of other families within the order ''Rhodocyclales'', and the family now contains the genera: *'' Rhodocyclus'' (type genus) species can grow photoheterotrophically or photoautotrophically (using molecular hydrogen as their electron donor) under anoxia or heterotrophically on fatty acids under air. Dominant respiratory quinone is rhodoquinone-8. Cells are curved rods or rings. *'' Propionivibrio'' species grow anaerobically by fermentation of hydrocarbons, yielding f ...

Microbial Fuel Cell
Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system that generates electric current by diverting electrons produced from the microbial oxidation of reduced compounds (also known as fuel or electron donor) on the anode to oxidized compounds such as oxygen (also known as oxidizing agent or electron acceptor) on the cathode through an external electrical circuit. MFCs can be grouped into two general categories: mediated and unmediated. The first MFCs, demonstrated in the early 20th century, used a mediator: a chemical that transfers electrons from the bacteria in the cell to the anode. Unmediated MFCs emerged in the 1970s; in this type of MFC the bacteria typically have electrochemically active redox proteins such as cytochromes on their outer membrane that can transfer electrons directly to the anode. In the 21st century MFCs have started to find commercial use in wastewater treatment. History The idea of using microbes to produce electricity was conceived in ...
