Gram-positive, coccoid cells 0.6-0.9 µm in diameter, grouped in pairs, tetrads and
clusters. Non-motile. Non-spore-forming.
clusters. Non-motile. Non-spore-forming.
Colonies are light yellow-pigmented, circular, somewhat convex and non-translucent
with glistening surfaces and entire margins and 2-3 mm in diameter. Growth occurs
at 10-40 ºC (optimum 25-30 ºC) and pH 6.5-10.5 (optimum pH 8.5), and in 0.5-20%
(w/v) NaCl (optimum 5-10% NaCl). Aerobic. Good growth also occurs in the presence
of 0.5-20% (w/v) KCl (optimum 5–8%) or 0.5-25% (w/v) MgCl2 6H2O (optimum 5-10%).
