Rods, 0.8-1.0 x 1.5-2.5 µm, occuring singly or in pairs and in chains. Nonmotile.
Can grow at 15 ºC, but not at 4 or 45 ºC. No growth in 4%, 6.5% or 8% NaCl media.
Isolated from beer.
Undetermined.

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 arginine hydrolysis (NH3 from arginine), chymotrypsin, alpha-glucosidase, fermentation of fructose,
glucose (acid and gas production), N-acetylglucosamine, maltose, and ribose.
Negative results for esculin hydrolysis, alpha- and beta-galactosidase, beta-glucosidase, urease, Voges-Proskauer reaction,
fermentation of amygdalin, arabinose, D-arabitol, arbutin, cellobiose, esculin, galactose, 2- and 5-ketogluconate, lactose, mannitol,
mannose, melezitose, melibiose, raffinose, rhamnose, salicin, sorbitol, sucrose, trehalose, methyl beta-D-xylopyranoside and xylose.
Fermentation with acid production from gluconate is variable.
