Dy.a.do.bac' ter. G. n. dyas two in number, pair; N.L. masc. n. bacter from the Gr. n. baktron rod or staff; N.L. masc. n. Dyadobacter rod or staff occurring in pairs. Bacteroidetes / Cytophagia / Cytophagales / Cytophagaceae / Dyadobacter Rods , 0.75–2 µm in length, in straight to curved arrangements , occurring in pairs (Figure 1) in young cultures and forming chains of coccoid cells in old cultures . Nonmotile. Nonsporeforming. Gram‐stain‐negative. Aerobic, chemoorganoheterotrophs, unable to hydrolyze cellulose or starch or gelatin. Oxidase‐ and catalase‐positive. Cells produce a non‐diffusible , yellow , flexirubin‐like pigment . The major fatty acids are C 15 : 0 iso, C 16 : 1 ω 5 c and C 16 : 1 ω 7 c . DNA G + C content ( mol %): 44–49.
