Gram-positive thin rods (0.5-0.7 x 2-3 μm) occurring singly and in short chains. Nonmotile.
Growth factor requirements: riboflavin, pyridoxal, pantothenic acid, niacin, and folic acid are essential. Can grow at 45 ºC; not at 15 ºC.
Isolated from swine waste-corn fermentation.
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: fructose, galactose, glucose, maltose, mannose,
and starch.
Negative results for fermentation of: amygdalin, cellobiose, lactose, mannitol,
melibiose, raffinose, salicin, sucrose, and trehalose.
