Sawabe, Fujimura, Niwa and Aono, 2007.
Gram-negative, rod-shaped cells, with rounded ends, 0.5-1.0 x 1.2-2.0 μm.
Nonmotile, nonflagellated. 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 ºC. No growth at 37 ºC.
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.
Isolated from the gut of the Californian red abalone (Haliotis rufescens).
Susceptible to vibriostatic agent O/157.
