Homotypic synonym: Companilactobacillus futsaii (Chao et al. 2012) Zheng et al. 2020.
Gram-positive rods, 0.7-0.8 / 1.5-10.0 µm, occurring singly, in pairs or in short chains.
Colonies are beige, smooth to rough, circular to slightly irregular, 2-3 mm in diameter
after 2 day in anaerobic incubation at 30 ºC on MRS agar. Can grow at 15 ºC, pH 4.0
and in 12% NaCl media. Weak growth at 10 ºC. No growth at 45 ºC.
Isolated from traditional fermented mustard products, fu-tsai and suan-tsai, in Taiwan.
Description is based mostly on API 50 CHL (bioMerieux) results.
