Gram-positive rods, grouped in chains.
Colonies on BHI medium after 48 h are circular, smooth, shiny with entire margins
roughly 0.3-0.4 mm in diameter. Haemolytic. Grows well in a temperature range of
30-40 ºC, with weak growth at 45 ºC. It tolerates a range of NaCl concentrations
(1-20%), with delayed growth between 7-20% in PY-X medium. Facultatively anaerobic.

Positive results for acid production (API 50 CHB) from: ribose, glucose, sorbose, aesculin, melezitose, gentibiose, D-tagatose and 5-
ketogluconate. Weak results for acid production from: D- and L-arabinose, D-lyxose, turanose, D- and L-xylose, fructose, mannose,
melibiose and sucrose.
Can utilize (Biolog GEN III): gentiobiose, D-fructose, D- and L-fucose, L-rhamnose, D-serine, D-fructose-6-phosphate, minocycline,
L-galactonic acid lactone, D-glucuronic acid, glucuronamide and sodium butyrate.
Negative results for catalase, oxidase, acid production from: methyl alpha-D-glucoside, methyl alpha-D-mannoside, 2-ketogluconate,
adonitol, amygdalin, arbutin, cellobiose, D- and L-arabitol, D- and L-fucose, dulcitol, erythritol, galactose, gluconate, glycerol,
glycogen, inositol, inulin, lactose, maltose, mannitol, N-acetylglucosamine, raffinose, rhamnose, salicin, sorbitol, methyl
beta-D-xyloside, starch, trehalose and xylitol.
