Gram-positive or variable, irregular rods, usually swollen and branched, 0.5-1.0 x 3-8
µm, occurring singly, in pairs or in chains. Non-motile.
µm, occurring singly, in pairs or in chains. Non-motile.
Colonies are white, smooth, 1-2 mm in diameter after 2 days of anaerobic incubation
on MRS agar supplemented with 50 mg/l L-cysteine. Optimum growth temperature
30-42 ºC. Weak growth at 30 ºC. No growth at 26 or 45 ºC. Grows at pH 5.0-7.0.
Facultatively anaerobic.

inositol, inulin, N-acetylglucosamine, methyl alpha-D-mannopyranoside, L-sorbose, trehalose, methyl beta-D-xylopyranoside, and L-
xylose.
Variable results for acid production from L-arabinose, arbutin, D-galactose, gluconate (weakly), glycerol (weakly), maltose, D-mannitol
(weakly), melezitose, raffinose, D-ribose, salicin, D-sorbitol (weakly), starch, trehalose, turanose, and D-xylose
