Gram positive, motile (peritrichous flagella) rods, 0.5-1.0 x 2.0-6.0 µm. Produces
ellipsoidal spores, swelling the sporangia. The spores do not tend to lie centrally in
the sporangia.
Grows on routine media (nutrient agar, TSA): nonpigmented, translucent, thin,
smooth, colonies of 2-3 mm in diameter. Aerobic. No anaerobic growth.
Maximum temperature 40 ºC; minimum temperature 10 ºC; optimum 28 ºC.
No growth in 3% NaCl. No growth at pH 5.6 or 9.
Isolated from child’s feces, clinical specimens, spinach and estuarine seagrass rhizosphere.
No growth in 0.001% lysozyme.
Isolated from clinical specimens.
