Geopsychrobacter electrodiphilus is a species of bacteria, the type species of its genus. It is a psychrotolerant member of its family, capable of attaching to the anodes of sediment fuel cells and harvesting electricity by oxidation of organic compounds to carbon dioxide and transferring the electrons to the anode.
In microbial communities, G. electrodiphilus could be similar to other Geobacteraceae. The community may ferment complex organic matter, thereby breaking up plant matter, for example; G. electrodiphilus would then oxidize the fermentation products (especially acetate) to carbon dioxide, whereby a terminal electron acceptor [e.g. iron(III) oxide] would be reduced. At least one strain (A1T) can oxidize hydrogen too.
Since G. electrodiphilus belongs to the Geobateraceae and can transfer electrons to the outside, one could assume that electron transfer to a methane producing archaeon could happen. There is another member of Geobacteraceae, well investigated for its interspecies electron transfer, even to a methanogen.
