Gram-negative rods, 0.4-0.8 x 1.5-3.0 μm with rounded ends. Occur as single units or
in pairs.
in pairs.
Colonies grown on YEM agar are creamy white in colour and mucoid. Temperature
range for optimal growth is 20-30 ºC, with no growth at 45 ºC. Growth is observed in
Nutrient Broth medium with 0%-10% NaCl and pH 4-8 at 28 ºC (optimal growth in 0%
NaCl, and at pH 6 and 7).
