Gram-negative rods, 0.5-1.3 x 1.5-3.0 μm. Non-capsulated. Motile by peritrichous
flagella. Non-spore-forming.
flagella. Non-spore-forming.
Colonies on nutrient agar are pale yellow, smooth, translucent and convex with entire
margins, about 1-2 mm (24-48 h) in diameter. Grows at 10-37 ºC with optimally at
20-30 ºC. Growth occurs in peptone water with 0-3.6% (w/v) NaCl; some strains grow
with up to 5.2 % NaCl (weaker growth). Growth occurs at pH 4.5-11 (optimally at pH
7-9). Facultatively anaerobic. Produces 2-isopropyl-3-methoxypyrazine giving a strong
potato-like odour.
