Gram-positive irregular cells with protuberances, knobs or branchings, 0.6-0.7 x
2.0-5.0 µm, occurring in pairs with wide angles, clumps of branched cells.
Non-motile. Non-spore-forming.

Non-motile. Non-spore-forming.
Colonies are smooth, convex, entire margins, cream to white, glistening, soft
consistency. The sediment in liquid cultures is flaky or in mold-like pellets and is
dispersed only with difficulty; the supernatant is clear. Grows at temperature 25-50 ºC
(optimum 39-40 ºC), pH 6.0-7.4 (optimum pH 6.5-7.0); no growth at pH 5.0 or 8.0.
Aerotolerance is variable.
