Geobacteraceae Holmes et al. 2004
General information
Description and emendation
The family Geobacteraceae is located within the domain Bacteria and the δ-subclass of the Proteobacteria. This family branches phylogenetically between the orders 'Desulfovibrionales' and 'Desulfobacterales'. The family Geobacteraceae comprises five genera: Geobacter, Desulfuromonas, Desulfuromusa, Pelobacter and Malonomonas. The type genus is Geobacter. Microorganisms within this family have mostly been isolated from anoxic sedimentary environments. All species of the Geobacteraceae are able to reduce Fe(III) and some are able to utilize S0 and/or the humics analogue AQDS as terminal electron acceptors. With the exception of Pelobacter and Malonomonas, all genera of the Geobacteraceae contain species that can oxidize acetate and other multi-carbon organic substrates to carbon dioxide. This family includes species with rod-like morphology, and members of all of the genera within this family, except Pelobacter, contain abundant c-type cytochromes. In addition, cells of members of the Geobacteraceae are non-motile or are motile by means of flagella.
