Gram-positive cocci, 0.5-0.8 µm in diameter. Some cells are oval in the very early
growth phase. Non-motile. Non-spore-forming.
growth phase. Non-motile. Non-spore-forming.
Colonies are smooth, circular, slightly convex or raised, glistening and 1.0-2.0 mm in
diameter after 5 days cultivation at 30 ºC on marine agar. Colonies on marine agar
are vivid yellow in colour at 30 ºC, but orange-yellow in colour at 25 ºC. Colonies on
solid PYGV medium are light yellow in colour at 25 and 30 ºC. Optimal growth
temperature is 25-30 ºC; growth occurs at 4 and 36 ºC, but not at 37 ºC. Optimal pH
for growth is 7.5-8.5; growth occurs at pH 6.0, but not at pH 5.5. Optimal growth occurs
in the presence of 2–5% (w/v) NaCl; growth occurs in the presence of 0-16% NaCl
(w/v). Aerobic.
