The Deferribacteraceae are a family of gram-negative bacteria which make energy by anaerobic respiration.[1]

Scientific classification
Domain: Bacteria
Phylum: Deferribacteres
Order: Deferribacterales
Family: Deferribacteraceae
Huber & Stetter 2002


Deferribacteraceae are rod-shaped, although the rods may be straight or bent. They are gram-negative. Deferribacteraceae perform anaerobic respiration using iron, manganese, or nitrate. They can also produce energy by fermentation. The type genus of the family is Deferribacter.[1]

'The All-Species Living Tree' Project

'The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB, SILVA rRNA database project, and LPSN, with the aim of assembling a database of 16S rRNA sequences of all validly published species of Bacteria and Archaea. At one stage, 23S sequences were also collected, but this has since stopped.Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species.


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


Calditerrivibrio is a genus of bacteria from the family of Deferribacteraceae with one known species (Calditerrivibrio nitroreducens). Calditerrivibrio nitroreducens has been isolated from a hot spring from Yumata in Japan.


Deferribacter is a genus in the phylum Deferribacteres (Bacteria).

Deferribacter autotrophicus

Deferribacter autotrophicus is an iron-reducing bacteria. It is thermophilic, anaerobic, chemolithoautotrophic, motile, straight to bent rod-shaped with one polar flagellum, 0.5–0.6 µm in width and 3.0–3.5 µm in length. The type strain is SL50T (=DSM 21529T =VKPM B-10097T).

Deferribacter desulfuricans

Deferribacter desulfuricans is a species of sulfur-, nitrate- and arsenate-reducing thermophile first isolated from a deep-sea hydrothermal vent. It is an anaerobic, heterotrophic thermophile with type strain SSM1T (=JCM 11476T =DSM 14783T).

Deferribacter thermophilus

Deferribacter thermophilus is an iron-reducing bacteria. It is a manganese- and iron-reducing bacterium. It is thermophilic and anaerobic bacterium, its type strain being designated as strain BMAT. The cells are straight to bent rods (1 to 5 by 0.3 to 0.5 μm).


Geovibrio is a Gram-negative, non-spore-forming, strictly anaerobic and motile genus of bacteria from the family of Deferribacteraceae.

Geovibrio ferrireducens

Geovibrio ferrireducens is a Gram-negative, Fe(III)-reducing, obligately anaerobic and motile bacterium from the genus of Geovibrio.

Geovibrio thiophilus

Geovibrio thiophilus is a Gram-negative, non-spore-forming and sulfur-reducing bacterium from the genus of Geovibrio which has been isolated from a drainage ditch in Konstanz in Germany.

List of bacteria genera

This article lists the genera of the bacteria.


Mucispirillum is a genus in the phylum Deferribacteres (Bacteria). It is represented by the single species Mucispirillum schaedleri|. It has been found in the intestinal tract of some rodents and considered a commensal with some association to disease. This species has been found in cockroaches mice, turkeys, dogs, pigs, goats, termites, and sometimes humans. It is anaerobic and does not form spores. It is motile, flagellated and thought to have the ability to move through mucus.
