Gram-positive rods with rounded ends, 1.0-1.2 x 3-6 µm, occuring singly or in pairs. Nonmotile.
Grows at temperature 15 ºC. No growth at 45 ºC.
Isolated from dental plaques and intestines of animals.

Facultatively heterofermentative (hexoses are fermented almost exclusively to lactic acid by the Embden-Meyerhof pathway or, at least
by some species, to lactic acid, acetic acid, ethanol, and formic acid under glucose limitations; pentoses are fermented to lactic acid
and acetic acid via an inducible phosphoketolase).
Positive results for fermentation of: cellobiose, esculin & melibiose.
Negative results for arginine hydrolysis, fermentation of: gluconate, mannitol, melezitose, sorbitol & xylose.
Variable results for fermentation of: arabinose, raffinose & ribose.
