Shieh, Chen and Chiu 2000.
Gram-negative, straight or curved rods, 0.6-0.8 x 2-3 µm, motile by double-sheathed
polar flagella. No lateral flagella on solid media. Accumulation of PHB inside the cells
is not observed.
Colonies on agar media are flat, circular, off-white and nonluminescent with an entire
margin. The species is a facultative anaerobe capable of both aerobic and anaerobic
Can grow in nutrient broth with: 6% NaCl. No growth in 0% NaCl, 1% NaCl, 8% NaCl,
10% NaCl & 12% NaCl.
Can grow at pH 10. Optimal growth at 30-35 ºC. No growth at 4 ºC or 40 ºC.
Isolated from sediment in a stand of seagrass, Taiwan.

Can utilize cellobiose, galactose, glucose, sucrose, mannose, xylose, citrate, fumarate, pyruvate, inositol, mannitol, l-alanine,
L-aspartate, L-glutamate, and L-threonine. The following compounds are not utilized as sole carbon and energy sources:
D-arabinose, lactose, melibiose, trehalose, acetate, beta-hydroxybutyrate, DL-malate, malonate, tartrate, adonitol, dulcitol, sorbitol,
L-arginine, L-glycine, L-lysine, L-methionine, L-ornithine, L-phenylalanine, L-tryptophan & L-valine.
Acid and gas are produced from fermentation of glucose, cellobiose, galactose, inositol, mannitol, mannose, sucrose and xylose.
D-arabinose, dulcitol, lactose, sorbitol and trehalose are not fermented.
Catalase, indole (Heart Infusion Broth, 1% NaCl), arginine (1% NaCl), gelatin hydrolysis (1% NaCl, 22°C), gas production from
D-glucose, nitrate reduction to nitrite & lipase are positive.
Negative for Voges-Proskauer (1% NaCl), oxidase, lysine (1% NaCl), ornithine (1% NaCl), L-arabinose, dulcitol, lactose & D-sorbitol.
