Yoon et al. 2003.
Gram-positive cocci, 0.6-1.1 μm diameter. Non-motile. Non-spore-forming.
Colonies are smooth, glistening, low convex, circular to slightly irregular and light
yellow in colour on Marine Agar. Optimal growth temperature is 20-25 ºC; growth
occurs at 4 and 34 ºC but not above 35 ºC. The optimal pH for growth is 7.0-8.0 and
no growth is observed at pH 5.5. Growth occurs in the presence of 14% NaCl but not
in the presence of 15% NaCl. No growth occurs in the absence of NaCl. The optimal
NaCl concentration for growth is 2-5% NaCl. Facultatively anaerobic.
Isolated from jeotgal, traditional Korean fermented seafood.
