Svec et al. 2006.
Gram-positive ovoid cocci, grouped in pairs, short chains or small groups. Nonmotile.
Colonies on sheep blood agar are nonpigmented, shiny, circular, smooth with entire
margins, 1 mm in diameter after 24 h of cultivation at 37 ºC.
Growth occurs in BHI broth at 10 ºC, no growth occurs at 45 ºC and is weak in
the presence of 6.5% NaCl and at pH 9.6. Poor growth on Slanetz–Bartley medium
containing 0.04% sodium azide, producing small dark-red colonies.
Isolated from a drinking water filter, in Silesia.
