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 °C with CO2. Non-hemolytic. V-factor independent growth.
Chemoorganotrophic. Yeast extract and CO2 stimulate growth. Growth occurs at 37 °C ,
but not at 20 °C or 45 °C.
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.
