Description is based on a single isolate.
Gram-variable, motile rods, 0.5–0.6 x 1.0–2.5 μm, single cells or pairs.
Produce ellipsoidal spores positioned terminally in swollen sporangia.
Produce ellipsoidal spores positioned terminally in swollen sporangia.
Colonies are convex with undulated margins and light yellowish-white, spreading as
single colonies over the entire plate. Aerobic; no anaerobic growth. Grow in TSB and
on TSA. Mesophilic, growth temperature 20 to 37 ºC, no growth at 40 ºC. Grow at
6.8-12.0 pH and in 2.5% NaCl, but not in 3% NaCl media.
