Gram-positive round to ovoid cells, grouped mostly in pairs or short chains. Nonmotie.
Endospores are not formed.
Pinpoint colonies on MRS agar plates are white, opaque and 0.4 mm in diameter.
Facultatively anaerobic. Good growth anaerobically on MRS agar at 30 ºC. Grows at
pH 4, at 35 ºC and in 3 % (w/v) NaCl but not at pH 3.5, at 40 ºC or in 6.5 % (w/v) NaCl.
Isolated from Chinese cabbage (Brassica rapa L. var. glabra Regel) sample taken from a commercial vegetable food factory in Japan.
