Gram-variable, rods, ≤0.9 µm mean cell width. Motile. Spores: centrally/terminally,
spherical endospores  in swollen sporangia. Cell-wall peptidoglycan contains
lysine, alanine, glutamic acid and aspartic acid in the molar ratio of 1.81 : 1.0 : 0.69 :
0.64 as diagnostic amino acids.
Colonies are  opaque and smooth. Aerobic. Grow at pH 6-9.5, in 2%, 5% & 7% NaCl
and at 17 - 37 ºC. Allantoin or urate are not required for growth.
Isolated from soil. Resistant to chloramphenicol (8µg/ml), erythromicyn (1µg/ml) & streptomycin (8µg/ml)  (weak).
Unknown.
