Gram-positive (early stages of growth) rods, 0.5 x 2-4 µm, occur as single cells, in
pairs, or in short chains. Nonmotile. Nonspore-forming.
Colonies grow well on MRS agar plates under both anaerobic and aerobic (air)
conditions. Colonies on MRS agar are yellowish-white, smooth and 1-2 mm in
diameter after incubation for 2 days at 30 ºC. Grow at 20-30 ºC. No growth at 10 or 37
ºC. Weak growth at 15 ºC. Grow in 5.5% NaCl, but not in 6.5% NaCl medium.
Isolated from flowers (Caltha palustris, a buttercup; Aster glehnii subsp. hondoensis, a chrysanthemum; Cirsium japonicum, a
plumed thistle;
Aster ageratoides subsp. ovatus, a chrysanthemum) in mountainous areas in Japan.
Undetermined.

Homofermentative.

Positive results for fermentation of: fructose, D-glucose (L-lactic acid is produced as
the end product; no gas production), and starch
(weak reaction).

Negative results for catalase, nitrate reduction, fermentation of: D-arabinose, cellobiose, galactose, gluconate, lactose, maltose,
mannitol, mannose, melezitose, melibiose, raffinose, rhamnose, ribose, salicin, sorbitol, sucrose, trehalose
, and D-xylose.
