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
growth.
Isolated from cotton-waste composts in Suwon, Korea. No growth in the presence of lysozyme.
Undetermined.

Positive results for catalase, hydrolysis of esculin, hydrolysis of urea, hydrolysis of
gelatin, hydrolysis of starch, nitrate reduction, acid production from L-arabinose,
D-glucose, D-mannitol & D-xylose.

Negative results for degradation of tyrosine, deamination of phenylalanine, egg yolk reaction, oxidase, indole production, hydrolysis of
