Gram negative, motile rods, 0.5-1.0 x 2.0-6.0 µm. Produces subterminally / terminally
ellipsoidal spore, swelling the sporangia.
Grows on routine media (nutrient agar, TSA): growth at 30°C is initially slow, with
more rapid growth following 24 h incubation; after 3–4 days the slightly umbonate
colonies are 1–8 mm in diameter, with slightly irregular margins. Colonies are
brownish-yellow, and have silky surfaces; the centers are opaque and the edges
translucent. Aerobic. No anaerobic growth. Maximum temperature 35 ºC; minimum
temperature 15 ºC; optimum 30 ºC. Grows at pH 6.0-8.5.
Isolated from a pharmaceutical fermentation plant and its antibiotic raw product.
Undetermined.
