Gram-positive, nonmotile, nonspore-forming rods.
Colonies on MRS agar are round, smooth, white, 1 mm in diameter. Facultatively
anaerobic. Optimum growth temperature is 35-37 ºC. No growth at 15 or 45 ºC.

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