Gram-positive irregular rods showing a rod-coccus cycle, 0.8-1.0 x 1.3-1.9 µm, and
occurring in pairs as typical V-forms.
occurring in pairs as typical V-forms.
Colonies on R2A agar and on nutrient agar are creamy to yellow after 3 days and
yellow after 6 days, round, convex, shiny, and with an entire margin. Colony diameter
is 1–1.5 mm after 3 days at 20 ºC on R2A agar. Growth occurs at 1-25 ºC, with
optimum at 20-25 ºC; no growth at 30 ºC. Grows in the presence of 0-5% (w/v) NaCl.
The pH range for growth is 6-9. Aerobic.
