Gram-positive, nonmotile rods that occur as single cells, in pairs, or occasionally in
short chains. On MRS-MOD medium with 1.2-propanediol as substrate, cells are 1
μm x 2 μm whereas, on glucose, the cells are longer, up to 10 μm. Nonspore-
forming.

Colonies are off-white on MRS medium. Facultatively anaerobic. Can grow in 0-2%
NaCl, but not in 4% NaCl medium. Optimum growth temperature 30-32 ºC. Can grow
at 15 ºC, but not at 12, 42, or 45 ºC. Grow at pH 4.0-7.0.

Isolated from maize silage in the Netherlands. It may play an important role in stabilizing maize silages.

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). Fermentative growth on
1,2-propanediol under anoxic conditions, producing propanol and propionic acid.
Positive results for alkaline phosphatase, cystine aminopeptidase, beta-glucosidase, valine aminopeptidase, fermentation of:
D-arabitol, L-arabinose, fructose, galactose, D-glucose, gentiobiose, gluconate, 5-ketogluconate, maltose, melibiose, methyl
alpha-D-glucoside, methyl beta-xyloside, raffinose, ribose, turanose, xylitol, and D-xylose.
Negative results for catalase, esterase (C4), esterase lipase (C8), alpha-fucosidase, fermentation of: adonitol, amygdalin, L-arabitol,
arbutin, D-arabinose, cellobiose, dulcitol, erythritol, fucose, glycerol, glycogen, inositol, inulin, 2-ketogluconate, lyxose, melezitose,
N-acetylglucosamine, rhamnose, sorbose, starch, trehalose, turanose, and L-xylose.
Variable and weak results for fermentation of esculin, lactose, D-mannose, D-mannitol, D-sorbitol, salicin, and sucrose.
