Gram-positive cocci, 1 µm in diameter. Non-motile. Non-spore-forming.
After 7 days incubation on GYP/sodium acetate/mineral salts agar, colonies are
smooth, low convex, circular, opaque, matt and white in colour. Grows on trypticase
soy agar at 30 ºC aerobically and in an anaerobic jar. No growth on R2A agar, nutrient
agar or MacConkey agar. Growth occurs at 15-30 ºC on GYP/ sodium acetate/mineral
salts agar but not at temperatures of 4 ºC or above 37 ºC. Optimum growth
temperature is 30 ºC. Optimal pH is 9.0. Grows at 0-8% (w/v) NaCl, optimally at 2-5%
(w/v) NaCl. Facultatively aerobic.
Isolated from the traditional Korean food kimchi in Daejeon, South Korea.
Undetermined.
