Empedobacter Vandamme et al. 1994
General information
Description and emendation
cells are gram-negative, nonmotile, non-spore-forming rods with parallel sides and rounded ends; typically the cells are 0.5 μm wide and 1 to 2 μm long. Intracellular granules of poly-β-hydroxybutyrate are absent. Aerobic, having a strictly respiratory type of metabolism. Chemoorganotrophic. All strains grow at 30°C; most strains grow at 37°C. Growth on solid media is light yellow. Colonies are circular, low convex, smooth, and shiny, with entire edges. Positive for catalase, oxidase, and phosphatase activities. Indole is produced. Several carbohydrates are oxidized, but glycerol and trehalose are not oxidized. Strong proteolytic activity occurs. Esculin is not hydrolyzed. Agar is not digested. Resistant to a wide range of antimicrobial agents. Fatty acids 15:0 iso, 16:1 ω7c, 16:1 ω5c, 16:0, 16:0 3-0H, and 17:0 iso 3-0H are predominant. Sphingophospholipids are absent. Menaquinone 6 is the only respiratory quinone. The DNA base composition ranges from 31 to 33 mol% G+C.
1: Colonies are non-pigmented or pigmented by flexirubin or non-flexirubin pigments. Aesculin hydrolysis is variable. Growth on MacConkey agar. Nitrates are not reduced. Fatty acids iso-C15:0 and iso-C17:0 3-OH are predominant. The major polar lipid is phosphatidylethanolamine. Menaquinone 6 is the predominant respiratory quinone. Homospermidine is the major polyamine. The DNA G+C content ranges from 31 to 35 %.
