Atopobiaceae Gupta et al. 2013
General information
Description and emendation
The family contains the type genus Atopobium and the genus Olsenella. The species from this family are saccharolytic rods and cocci. They do not from spores or flagella and are strictly or facultatively anaerobic. These organisms produce lactic acid, acetic acid, formic acid, ethanol and hydrogen as products of glucose fermentation. The DNA G+C content for members of the family ranges from 35 mol% to 64 mol%. The species from this family form a distinct clade in phylogenetic trees, and they are distinguished from all other members of the class Coriobacteriia by the conserved signature indels described in this report in the following proteins: class V amino-transferase, lysine-tRNA ligase, ppGpp synthetase I SpoT/ RelA, putative translation elongation factor G, DNA translocase FtsK, THUMP domain-containing protein and a CinA domain protein.
1: The description is as given before (Gupta et al., 2013) with the following additions. Obligately or facultative anaerobe, Gram-stain-positive, non-motile, catalase-negative organisms that form short rods, which often show central swellings or small cocci which may be elliptical. The main fermentation products from glucose are lactic acid with acetic and fumaric acids. Growth is enhanced by Tween 80. The G+C content is around 35–46%.
