Bacteroidetes / Flavobacteriia / Flavobacteriales / Flavobacteriaceae / Subsaxibacter Small coccibacilli , 0.4–1.0 × 0.3–0.5 µm. Gram‐stain‐negative . Cells occur singly or in pairs. Spores and resting cells are not present. Gas vesicles and helical or ring‐shaped cells are not formed. Gliding motility is present . Strictly aerobic . Oxidative metabolism . Catalase‐positive . Oxidase weakly positive . Chemoheterotrophic . Colonies are orange due to production of carotenoids. Flexirubin pigments are not produced . Sodium ions are required for growth. Best growth occurs in organic media containing seawater salts. Psychrophilic . Grows between −2 and 20°C, with temperature optima at 10–15°C in seawater or NaCl‐containing media. Neutrophilic, with optimal growth occurring at about pH 7.5–8.0. The major fatty acids include C 15:1 iso ω10 c , C 15:1 anteiso ω10 c , C 15:0 iso, C 15:0 anteiso, C 16:1 ω7 c , C 17:1 , and C 16:0 3‐OH iso. The major isoprenoid quinone is menaquinone‐6 . Habitat: Antarctic quartz stone sublithic cyanobacterial biofilms. DNA G + C content ( mol %): 35. Type species : Subsaxibacter broadyi Bowman and Nichols 2005, 1481 VP .
