Gram-positive, ovoids to short rods, approximately 0.7-0.9 × 0.8-1.1 µm. Non-motile.
Non-spore-forming. No rod-coccus life cycle.
Non-spore-forming. No rod-coccus life cycle.
Colonies on TSA after 3 days incubation at 30 ºC are yellow, circular, opaque and
convex with entire margins, 1 mm in diameter. Temperature range for growth is 4-37 ºC
(optimal growth at 28-30 ºC). The pH range for growth is 6-10; optimum pH 8-9. Grows
iin the presence of 0-7 % (w/v) NaCl; no growth in the presence of 8 % NaCl. Strictly
aerobic.
