Nonmotile.
Colonies are white to gray, 1-5 mm in diameter, semi-rough, often with raised areas.
Facultatively anaerobic. Can grow at 30-45 ºC; not at 22 or 48 ºC.

Obligately heterofermentative (hexoses are fermented to lactic acid, acetic acid
(ethanol), and CO2 via the phosphogluconate pathway; pentoses are fermented
to lactic acid and acetic acid by the related pentose phosphate pathaway).
Positive results for fermentation of: galactose, glucose (acid), lactose, levulose, maltose, mannose, melibiose, raffinose, and
sucrose.
Negative results for catalase, fermentation of: N-acetylglucosamine, adonitol, arbutin, arabinose, arabitol, cellobiose, dulcitol,
erythritol, fucose, gentiobiose, glycerol, glycogen, inositol, inulin, 2 and 5-ketogluconate, lyxose, mannitol, melezitose, rhamnose,
salicin, sorbitol, sorbose, starch, tagatose, trehalose, turanose, xylose, and xylitol.
Variable and weak results for esculin and ribose fermentation.
