Long and Gu 2019.
Gram-positive rods, 0.8-1.5 / 2-10 µm, occurring singly. Non-motile. Non-spore-forming.
Colonies are white, convex, smooth, sometimes rough with entire edges, 1mm in
diameter after 2 days at 30 ºC on mMRS agar. Facultative anaerobe. Grows at
temperature range 15-37 ºC (optimally at 30 ºC). Variable growth at 37 ºC. Can grow
at pH 5.0-9.0. Can grow in 6.0% NaCl, but not in 6.5% NaCl media.
Isolated from traditional pickle, China. Tellurite tolerant.
Description is based mostly on API 50 CHL (bioMerieux) results.
