Kim, Go and Lee 2007.
Gram-positive, motile (a single polar flagella) rods, 0.5-0.7 x 2.0-3.0 µm. Produce
subterminal / terminal, ellipsoidal endospores in swollen sporangia.
Colonies are yellowish white, 2-3 mm in diameter after 2 days incubation on TSA.
Grow at pH 6-8 (optimum pH 7), in 0-5% NaCl media and at 15-50 ºC (optimum 30
ºC). Aerobic, facultatively anaerobic. NaCl, allantoin or urate are not required for
Isolated from cotton-waste composts in Suwon, Korea. No growth in the presence of lysozyme.
