Khianngam, Akaracharanya, Tanasupawat, Lee and  Lee, 2009.
Gram-positive, motile (peritrichous flagella) rods, 1-1.2 x 3-8 µm. Produce
ellipsoidal, central / subterminal spore in swollen sporangium.
Colonies are white,  convex,  1-3 mm in diameter after incubation at 37 ºC 2 days  on
C agar  (5 g peptone Difco, 1 g yeast extract Difco, 4 g K
2HPO4, 1 g MgSO4 * 7H2O, 0.2
g KCl,0.02 g FeSO
4  * 7H2O and 1000 ml distilled water and adjusted to pH 7.0).
Aerobic and anaerobic growth. Growth temperature 20-45 ºC, optimum 37 ºC. No
growth at 15 or 50 ºC. Can grow in 3%, but not in  5% NaCl. Grow at pH 6.5-9
(optimum pH 7.5), but not at pH 5-6.
The type strain was isolated from soil in Thailand.
Undetermined.
