Gram-positive, short rods, 0.4-0.5 x 1.2-1.4 µm. Non-motile. Non-spore-forming.
Colonies after 24 h incubation at 40 ºC on LB medium, are smooth, circular, opaque
and yellow in colour and 1.0-1.5 mm in diameter. Optimum temperature for growth is
40-42 ºC and the optimal pH is 9.0-10.0. Growth occurs in the presence of 0-10 %
NaCl.
