Wei and Gu 2019.
Gram-positive rods, 1/1-2 µm, occurring in pairs or in short chains. Non-motile.
Colonies on modified MRS agar are white, convex, smooth with entire edges, 1.0-1.5
mm in diameter after 3 days incubation at 37 ºC. Facultative anaerobe. Grows at
temperature range 15-37 ºC (optimally at 30 ºC). Can grow at pH 5.0 and in 6.5%
NaCl. No growth at 45 ºC or pH 11.0.
Isolated from traditional pickle, in China. Positive tellurite tolerance.
Description is based mostly on API 50 CHL (bioMerieux) results.
