Firmicutes / Clostridia / Clostridiales / Lachnospiraceae / Acetatifactor

Strictly anaerobic Gram-positive rods. Phylogenetically most closely related to members of the family Lachnospiraceae within the Firmicutes (<90% 16S rRNA gene sequence identity). Cells grow under strictly anoxic conditions and produce acetate and butyrate. They do not metabolize glucose and are positive for phenylalanine arylamidase, in contrast to members of most closely related genera. Major cellular fatty acids are C14:0 and C14:0 DMA (dimethyl acetal derivatives). In addition to the type species Acetatifactor muris, 16S rRNA gene-based diversity estimation indicates the existence of three other yet-to-be-cultured species clusters. The preferential habitat of all species is the large intestine of rodents.

DNA G + C content (mol%): 48.5 (T m); 47.7 (draft genome).

Type species: Acetatifactor muris Pfeiffer, Desmarchelier, Blaut, Daniel, Haller and Clavel 2013, 1VP (Effective publication: Pfeiffer, Desmarchelier, Blaut, Daniel, Haller and Clavel 2012, 906).
