See text The Deferribacteraceae are a family of gram-negative bacteria which make energy by anaerobic respiration.

[2] Deferribacteraceae are rod-shaped, although the rods may be straight or bent.

Deferribacteraceae perform anaerobic respiration using iron, manganese, or nitrate.

The type genus of the family is Deferribacter.

[2] The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LSPN) [3] [4] Limisalsivibrio Spring et al. 2022 Geovibrio Caccavo et al. 2000 Denitrovibrio Myhr & Torsvik 2000 Seleniivibrio Rauschenbach et al. 2013 Mucispirillum Robertson et al. 2005 Calditerrivibrio Iino et al. 2008 Deferrivibrio Zavarzina et al. 2023 Petrothermobacter Tamazawa et al. 2017 Flexistipes Fiala et al. 2000 Deferribacter Greene et al. 1997 Mucispirillum Limisalsivibrio Geovibrio Denitrovibrio Seleniivibrio Flexistipes Calditerrivibrio Deferrivibrio Deferribacter The family was first described in 2001 in order to hold the genera Deferribacter, Flexistipes, and Geovibrio.
