Actinobacteria / Actinobacteria / Micrococcales / Beutenbergiaceae / Beutenbergia

Cells are irregular rods or cocci occur singly, in pairs, shortchains, or clusters and exhibit a rod–coccus growth cycle. Gram-stain positive, not acidfast. Endospores are not formed. Nonmotile. Aerobic to microaerobic. Colonies grown on rich (R) agar are smooth, circular, convex, opaque with entire margins, and cream to bright yellow in color. Good growth on complex organic media at 28°C. Oxidase negative, catalase positive. The peptidoglycan type is A4α based on L-lysine. The acyl type is acetyl. Whole cell sugars are glucose, mannose, and galactose. The predominant menaquinone is MK-8(H₄ ); MK-8(H₂), MK-8, and MK-9(H₄) occur in minor amounts. The polar lipids consist of phosphatidylinositol, diphosphatidylglycerol, and unknown phospholipids. The cellular fatty acid profile is dominated by iso- and anteiso-branched-chain acids. Mycolic acids are absent. Based on 16S rRNA gene sequence similarities, strains of Beutenbergia are closely related both to the genera of the families Beutenbergiaceae (Salana, Serinibacter, and Miniimonas) and Bogoriellaceae (Georgenia and Bogoriella) and to the genera Cellulosimicrobium (Promicromonosporaceae), Sanguibacter (Sanguibacteraceae) and Intrasporangium (Intrasporangiaceae) and the genus Ruania.

DNA G + C content (mol%): 71 (HPLC), 73.1 (complete genome sequence).
