The Desulfuromonadales are an order within the Proteobacteria. Various members of the Desulfomonadales are capable of anaerobic respiration utilizing a variety of compounds as electron acceptors, including sulfur, Mn(IV), Fe(III), nitrate, Co(III), Tc(VII), U(VI) and trichloroacetic acid[1][2]

The order Desulfuromonadales contains the following families and genera:[3]

The suffix -bacter is in microbiology for many genera and is intended to mean "bacteria".


The Deltaproteobacteria are a class of Proteobacteria. All species of this group are, like all Proteobacteria, Gram-negative.

The Deltaproteobacteria comprise a branch of predominantly aerobic genera, the fruiting body-forming Myxobacteria which release myxospores in unfavorable environments, and a branch of strictly anaerobic genera, which contains most of the known sulfate- (Desulfovibrio, Desulfobacter, Desulfococcus, Desulfonema, etc.) and sulfur-reducing bacteria (e.g. Desulfuromonas spp.) alongside several other anaerobic bacteria with different physiology (e.g. ferric iron-reducing Geobacter spp. and syntrophic Pelobacter and Syntrophus spp.).

A pathogenic intracellular deltaproteobacterium has recently been identified.


Desulfuromonas is a Gram negative bacterial genus from the family of Desulfuromonadaceae. Desulfuromonas can reduce elemental sulfur to H2S. Desulfuromonas occur in anoxic sediments and saline lakes.

Desulfuromonas acetoxidans

Desulfuromonas acetoxidans is a species of bacteria. It is strictly anaerobic, rod-shaped, laterally flagellated and Gram-negative. It is unable to ferment organic substances; it obtains energy for growth by anaerobic sulfur respiration.

Desulfuromonas chloroethenica

Desulfuromonas chloroethenica is a gram-negative metal-reducing proteobacterium. It uses tetrachloroethylene and trichloroethylene as electron acceptors.

Desulfuromonas michiganensis

Desulfuromonas michiganensis is a species of tetrachloroethene-reducing, acetate-oxidizing anaerobic bacteria.

Desulfuromonas svalbardensis

Desulfuromonas svalbardensis is a species of psychrophilic, Fe(III)-reducing bacteria. It is Gram-negative, rod-shaped and motile. Its type strain is 112T (=DSM 16958T =JCM 12927T) .


Geopsychrobacter is a genus of bacteria from the family of Geobacteraceae.

Geoalkalibacter ferrihydriticus

Geoalkalibacter ferrihydriticus is a Gram-negative, obligately anaerobic, non-spore-forming, iron-reducting bacterium from the genus of Geoalkalibacter which has been isolated from sediments from the Lake Khadin in Russia.


Geobacter is a genus of Proteobacteria. Geobacter species are anaerobic respiration bacterial species which have capabilities that make them useful in bioremediation. Geobacter was found to be the first organism with the ability to oxidize organic compounds and metals, including iron, radioactive metals, and petroleum compounds into environmentally benign carbon dioxide while using iron oxide or other available metals as electron acceptors. Geobacter species are also found to be able to respire upon a graphite electrode. They have been found in anaerobic conditions in soils and aquatic sediment.

Geobacter bemidjiensis

Geobacter bemidjiensis is a Fe(III)-reducing bacteria. It is Gram-negative, slightly curved rod-shaped and is motile via means of monotrichous flagella. Its type strain is BemT (=ATCC BAA-1014T =DSM 16622T =JCM 12645T).

Geobacter lovleyi

Geobacter lovleyi is a gram-negative metal-reducing and tetrachloroethene-dechlorinating proteobacterium.It has potential as a bioremediation organism, and is actively researched as such.

Geobacter metallireducens

Geobacter metallireducens is a gram-negative metal-reducing proteobacterium. It is a strict anaerobe that oxidizes several short-chain fatty acids, alcohols, and monoaromatic compounds with Fe(III) as the sole electron acceptor. It can also use uranium for its growth and convert U(VI) to U(IV).Geobacter metallireducens was discovered by Derek Lovely at UMass Amherst in 1993. It is an iron-reducing bacteria and it has been thought that the microbe could be used to treat industrial sites where “cyanide-metal complexes” have formed to contaminate the site. This microbe only grows a flagella when it is needed, like when the environment is not to its liking. Geobacter metallireducens becomes motile when necessary.The genome of Geobacter metallireducens has a chromosome length of 3,997,420 bp. It has a circular bacterial chromosome, meaning there are no free ends of DNA. The shape is roughly like that of an egg. Geobacter metallireducens also has a GC content of 59.51%. The plasmid has a lower GC content, of 52.48%, and is 13,762 bp in length. The plasmid encodes a stabilizing protein, RelE/ParE, which allows Geobacter metallireducens to adapt and thrive in different and new environmental conditions.

Geobacter psychrophilus

Geobacter psychrophilus is a Fe(III)-reducing bacterium. It is Gram-negative, slightly curved, rod-shaped and motile via means of monotrichous flagella. Its type strain is P35T (=ATCC BAA-1013T =DSM 16674T =JCM 12644T).

Geobacter sulfurreducens

Geobacter sulfurreducens is a gram-negative metal and sulphur-reducing proteobacterium. It is rod-shaped, obligately anaerobic, non-fermentative, has flagellum and type four pili, and is closely related to Geobacter metallireducens. Geobacter sulfurreducens is an anaerobic species of bacteria that comes from the family of bacteria called Geobacteraceae. Under the genus of Geobacter, G. sulfurreducens is one out of twenty different species. The Geobacter genus was discovered by Dr. Derek R. Lovely in 1987. G. sulfurreducens was first isolated in Norman, Oklahoma, USA from materials found around the surface of a contaminated ditch.

Geobacter toluenoxydans

Geobacter toluenoxydans is a bacterium from the genus of Geobacter which has been isolated from sludge from an aquifer in Stuttgart in Germany.

Geobacter uraniireducens

Geobacter uraniireducens is a Gram-negative, rod-shaped and motile bacterium from the genus of Geobacter.


Malonomonas is a Gram-negative, non-spore-forming, chemoorganotrophic, anaerobic and motile genus of bacteria with single polar flagellum from the family of Pelobacteraceae with one known species (Malonomonas rubra).Strains of Malonomonas have been isolated from anoxic sediments. the bacteria Malonomonas rubra bacteria metabolizes malonate.


Pelobacteraceae is a bacterial family in the order Desulfuromonadales. The species are anaerobic and have a fermentative metabolism.
