Gram-negative, motile rods, 0.5-1.4 x 2-8 μm. Produce oval spores; usually not
swelling the sporangium.
swelling the sporangium.
Colonies on peptone-urea agar are whitish; colonies sink into the agar within a few
days, but do not liquefy it. Aerobic. No anaerobic growth.
Mesophilic, maximum growth temperature 35-40 ºC, optimum 30 ºC. No growth at pH
5.7 or in 5% NaCl. Growth is inhibited by peptones but inhibition may be neutralized
by urea.

Isolated from soil (Germany, Yugoslavia, Mexico, England). Susceptible to lysozyme.
