The family Beu.ten.ber.gi.a.ce'ae. currently accommodates the genera Beutenbergia, Salana, Serinibacter, and Miniimonas. Cells are irregular rods and cocci that occur singly, in pairs, or in small clusters. Gram-stain positive. Endospores are not observed. Nonmotile. Aerobic and facultatively anaerobic. Colonies are circular, convex, and vary in color from white to yellow. Grow well on complex organic media and utilize a broad spectrum of carbon sources. Optimum growth at 28 and 37°C. Oxidase positive or negative, catalase positive. Characteristic diamino acids in the peptidoglycan are L-lysine or L-ornithine that correspond to peptidoglycan types A4α or A4β, respectively. The major menaquinone is MK-8(H4). The polar lipid pattern consists of diphosphatidylglycerol and (except Serinibacter) several unidentified phospholipids, and possibly phosphatidylglycerol, phosphatidylinositol, and phosphatidylethanolamine. Cellular fatty acid profiles are dominated by iso- and anteiso-branched-chain acids and minor amounts of saturated straight-chain acids. Harbors specific 16S rRNA gene sequence signatures differentiating the family from other related families. Isolation sources are cave soil, sea sand, rhizosphere of a mangrove, an aerobic bioreactor, and the intestinal tract of a fish. DNA G+C content (mol%): 71–75. Type genus: Beutenbergia Groth, Schumann, Schuetze, Augsten, Kramer, and Stackebrandt 1999, 1738VP.
