Description is based on a single isolate.
Gram-positive (but with the onset of spore formation, the cells became Gram-
negative), rods, 0.5-0.9 x 2.3-4.5 μm. Motile by peritrichous flagella. Produce   
ellipsoidal spores in swollen sporangium.
3 types of colonies are formed on TSA: circular, flat, smooth and opaque; circular,
convex, glistening and translucent; and circular or irregular, wrinkled hollow and
opaque. Grow on soybean meal media.
Aerobic and anaerobic growth. Can grow at 10-50 ºC. Grows optimally on blood agar
at 38-40 ºC. No growth in 7% NaCl media.
Isolated from a compost sample prepared with rice husk and fishery industrial wastes collected from Chinju, Republic of Korea,
using the standard dilution agar plating method with minimal salt agar medium supplemented with 0.2% (w/v) colloidal chitin.
Resistant to lysozyme 0.001%.
Produces an iturin-like antifungal antibiotic; the strain showed strong antifungal activity against
Rhizoctonia solani, a plant-pathogenic
fungus,
Fusarium oxysporum, Colletotrichum lagenarium, Sclerotinia sclerotiorum and Botrytis cinerea.
Undetermined.
