Phylum Proteobacteria, Class Gammaproteobacteria, Order Vibrionales, Family Vibrionaceae, Genus Vibrio, Vibrio halioticoli
Sawabe, Sugimura, Ohtsuka, Nakano, Tajima, Ezura and Christen 1998.
Gram-negative, curved rods, nonmotile, nonflagellated. No lateral flagella on solid
media. No swarming on complex media. Cells bind to and utilize alginic acid. Cells
are rod-shaped, with rounded ends, and are 0.6-0.4 µm in diameter and 1.7-2.0 µm
long when the organism is grown in ZoBell 2216E broth, but cells are spherical
shaped 0.7-1.0 µm in diameter and 1.9-1.6 µm long when the organism is grown in
ZoBell2216E broth containing alginate.
Colonies on ZoBell 2216E agar are beige, circular, smooth and convex with entire
edge. No luminescence or pigmentation are produced.
Can grow in nutrient broth with: 3% NaCl. No growth in 1% NaCl or 6% NaCl.
Optimal growth at 30 ºC. No growth at 4 or 40 ºC.
Isolated from gut of the abalone Haliotis discus hannai (a rock-climbing gastropod mollusk), where this bacterium may aid in the
digestion of algae that contain alginic acid.
