clusters. Non-motile. Non-spore-forming.
clusters. Non-motile. Non-spore-forming.
Colonies after 4 days incubation on TSA at 28 ºC are red, convex, round and 1.0 mm
in diameter. Growth occurs at 0-34 ºC (optimally at 25-28 ºC), pH 6.0–9.0 (optimally at
pH 7.0) and in the presence of 0-4.0% (w/v) NaCl. Aerobic.
