Description is based on a single isolate.
Gram-variable rods. Produce ellipsoidal, subterminal spore in swollen sporangium.
Colonies are smooth, flat, bright, 1-2 mm in diameter and translucent on nutrient
agar. Non-haemolytic. Aerobic and anaerobic growth. Optimum growth temperature
25-30 ºC. No growth at 50 ºC. No growth in 5 or 7% NaCl. Grow at pH 8.5.
The type strain was isolated from surface-sterilized seeds of the garden pea Pisum sativum. Habitat is not known.
Sensitive to cephalothin, vancomycin, erythromycin, tetracycline & piperaillin. Resistant to clindamycin and chloramphenicol.
Undetermined.
