Gram-positive, short to long rods (0.5–1.5 x 1.5–10 μm) occurring singly, in pairs and
in short chains. Nonspore-forming.
in short chains. Nonspore-forming.
Colonies on BL (glucose-blood liver) agar plates are 0.5 to 2.0 mm in diameter,
circular to slightly irregular, entire, grayish brown to reddish brown, and rough.
Facultatively anaerobic. Can grow at 15-45 ºC, and in 4% NaCl medium.

Obligately homofermentative (hexoses are fermented almost exclusively to lactic acid
by the Embden-Meyerhof pathway; pentoses or gluconate are not fermented).
Positive results for fermentation of: amygdalin, cellobiose, esculin, fructose, galactose, glucose (without gas production), maltose,
mannose, melibiose, raffinose, salicin and sucrose.
Negative results for catalase, fermentation of: arabinose, mannitol, melezitose, rhamnose, ribose, sorbitol, trehalose & xylose.
Variable fermentation of lactose and starch.
