Gram-positive rods, 0.57 x 1.29 μm. Motile (flagella). Non-spore-forming.
Colonies on R2A medium are circular, convex and yellow. Growth occurs on LB, PDA,
TSA, R2A and NA, but not on MacConkey agar. Growth occurs at 4–34 ºC (optimally at
30 ºC), at pH 4-10 (optimum pH 7), and with 0-5 % (w/v) NaCl. Aerobic.
