Gram-positive rods (0.9-1.0 x 1.5-2.5 µm) with rounded ends, that occur in pairs,
rarely in single or in short chains (depending on the medium for growth).
Non-spore-forming. Non-motile.

Non-spore-forming. Non-motile.
Colonies on xylose-YP agar for 48 h at 30 ºC are 2 mm in diameter; CaCO3 is clearly
dissolved on the plate. The liquid culture is highly turbid and the cells precipitate
gradually in xylose-YP broth and glucose-YP broth. Optimum growth temperature is
30 ºC. Can grow at 20-40 ºC; not at 45 ºC. Variable growth at 15 ºC. Range of pH
4.5-7.5. Growth factor requirements: thiamine, riboflavin, pantothenic acid, niacin and
biotin are essential.

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: arabinose, D-glucose (acid is produced in more than 4 days; gas is produced under anaerobic
conditions), gluconate (acid and gas are produced), maltose, ribose and xylose.
Negative results for arginine hydrolysis (NH3 from arginine), catalase, gelatin liquefiaction, nitrate reduction, fermentation of:
cellobiose, esculin, glycerol, inulin, lactose, mannitol, mannose, melezitose, melibiose, raffinose, rhamnose, salicin, sorbitol, starch,
sucrose, trehalose and xylan. Litmus milk is not changed.
Variable and weak results for fructose and galactose fermentation.
