Gram-positive rods (0.6-1.0 x 2.0-20.0 μm) occurring singly, in pairs and in short
chains. Nonmotile.
Colonies on MRS agar (at 37 ºC after 2 days) are 1.2-2.1 mm in diameter, circular to
slightly irregular, convex, opaque, rough, and white. Facultatively anaerobic. Can grow
at 45 ºC, but not at 15 ºC.
Isolated from chicken small intestine.
Undetermined.

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: esculin, fructose, galactose, glucose (acid, without gas production), maltose, mannose, and
sucrose.

Negative results for catalase,  fermentation of: amygdalin, arabinose, melezitose, melibiose, raffinose, rhamnose, ribose, sorbitol,
trehalose, and xylose. Milk is not curdled.

Variable results for fermentation of: cellobiose, lactose (weak), mannitol (weak), and salicin.
