Gram-positive, ovoid cocci, 1 µm in diameter. Non-motile.
Grow equally well under aerobic, anaerobic and microaerophilic conditions. Growth
occurrs aerobically from 4-30 ºC (type strain 4-25 ºC, optimum 10-25 ºC), with
0-3%NaCl (type strain 0-2.5%, optimum 0-2%) and at pH 5-8.5 (optimum 6-7.5) on
TSA. Facultatively anaerobic.

Isolated from high-oxygen modified atmosphere packaged beef steaks purchased in Freising, Germany.
