Rods with rounded ends, 0.6-0.8 x 3.0-8.0 µm, with tendency to form “snakes” and,
after prolonged incubation, long characteristically wrinkled chains. Nonmotile.

In broth cultures, a flocculent sediment is observed. Colonies are grayish and flat.
Can grow at 15 ºC, but not at 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 fermentation of: amygdalin, cellobiose, galactose, lactose, maltose, mannose, and salicin.
Negative results for arginine hydrolysis, indole production, lipase, urease, fermentation of: mannitol, melibiose, raffinose, sucrose,
and trehalose.
