motile, non-flagellated. No endospores or capsules are formed.
Can grow in nutrient broth with 1% & 6% NaCl. No growth in 0% or 1% 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 growth factors requirement.
