Gram-negative rods. Non-motile. Non-sporeforming.
Colonies are circular, convex, entire, cream in colour and 1.0-1.5 mm in diameter on
R2A agar after 3 days of incubation at 28 ºC. Growth also occurs on NA, LB agar, MA
and ISP2 agar. Grows at 10-55 ºC (optimally at 28 ºC), pH 3.0-8.0 (optimally at pH 6.0)
and with 0-4.0% (w/v) NaCl, optimmum in 0% NaCl. Strictly aerobic.
