Gram-positive short, slender rods, 0.6-0.8 x 1.5-2.5 µm. Nonmotile.
Can grow at 15-37 ºC; no growth at 4, 10, 45 or 50 ºC. Grows at pH 5.0-10.0 and in
1-9% NaCl.
1-9% NaCl.
Isolated from marinated fish products, meat products (fermented sausages, sliced prepacked sausages), and sourdough.

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).

beta-glucosidase, beta-galactosidase, N-acetyl-beta-glucosaminidase, leucine arylamidase, naphthol-AS-BI-phosphohydrolase,
valine arylamidase, Voges-Proskauer test, fermentation of arbutin, fructose, galactose, glucose, gentibiose (weak), mannose, salicin,
trehalose, N-acetylglucosamine, cellobiose, esculin, ribose, and sucrose.
