Gram negative, rod-shaped cells, with rounded ends, 0.5-1.0 x 1.2-2.0 μm. Non-
motile, non-flagellated. No endospores or capsules are formed.
motile, non-flagellated. No endospores or capsules are formed.
Can grow in nutrient broth with: 1% & 6% NaCl. No growth in 0% NaCl. Growth occur
at 4 to 30 °C. No growth at 37 °C.
Colonies on agar (ZoBell 2216E) are smooth, beige, convex . Colonies are green on
TCBS agar (selective media : thiosulfate-citrate-bile salts-sucrose agar).
Facultatively anaerobic, mesophilic, neutrophilic ,chemo-organotroph. No
luminescence. No requirement for organic growth factors.
