Gram-negative pleomorphic rods; 0.8 x 1 µm, nonmotile. Filamentous cells are occasionally seen: “morse code” forms and chains
are common in growing broth culture. Cells within an extracellular matrix are common in aerobically grown cultures.
are common in growing broth culture. Cells within an extracellular matrix are common in aerobically grown cultures.
Colonies are circular, gray, translucent on TSB agar, 1-1.5mm diameter after 24
hours at 37 ºC with CO2. Non-hemolytic. V-factor independent growth.
Chemoorganotrophic. Yeast extract and CO2 stimulate growth. Growth occurs at 37
ºC, but not at 20 or 45 ºC. Marked production of succinic acid in presence of CO2 and
high substrate concentration.

Isolated from the bovine rumen.
Bacteria is adapted to a symbiotic living in the bovine rumen.
