Gram-positive slender and slightly curved rods, 2.0-8.0 µm long with tapered ends,
occurring in irregular chains; often cells are poorly refractile and appear as empty or
vacuolized. Non-motile. Non-spore-forming.

Colonies are convex, entire, cream to white, soft, glistening. Growth temperature 30-
45 ºC (optimum 37-39 ºC); no growth at 29 or 46.5 ºC. Optimum pH range is 6.7-6.9;
no growth at pH 5.5 or 8.7. Anaerobic.
