Fri.ed.man.ni.el'la. N.L. fem. dim. n. Friedmanniella named after E. Imre Friedmann (1921–2007), an American microbiologist, in recognition of his contributions to Antarctic microbiology. Actinobacteria / Actinobacteria / Propionibacteriales / Propionibacteriaceae / Friedmanniella Spherical to ellipsoidal cells that occur mostly in more or less regular packets which develop through cell division in three perpendicular planes. The packets aggregate, forming clusters. Gram‐stain‐positive. Nonmotile . Nonsporeforming. Nonacid‐fast. Strictly aerobic. Oxidase‐negative. Catalase‐positive . Chemo‐organotrophic. Only a few carbohydrates, organic acids, and other carbon sources are metabolized. The peptidoglycan type is A3 γ' containing LL ‐ diaminopimelic acid , glycine in position 1 of the peptide subunit, and a single glycine residue as interpeptide bridge. The major menaquinone is MK‐9(H 4 ), and the main fatty acids are 12‐ and 13‐methyltetradecanoic acid ( C 15:0 anteiso and C 15: 0 iso). Mycolic acids are absent. The phospholipid pattern includes phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol , and one unknown phospholipid. DNA G + C content ( mol %): 69–74.
