Gram-variable straight or slightly curved, round-ended, rods 0.8-1.0 x 3.0-8.0 µm,
occurring singly and in pairs. Motile. Produce terminally, spherical endospores in
swollen sporangia. Endospore formation is slow and scarce on NA MnSO4 after 10
days incubation at 30 ºC. On 1/2 BFA, endospores are formed abundantly after
approximately 3 days incubation at 30 ºC.

Colonies are are butyrous, glossy, cream-coloured, semi-translucent and slightly
raised, with irregular margins that may spread along the inoculation streak, 1-2 mm
in diameter. On casein agar produces a pale-pink, diffusible pigment. Growth occurs
at 20 and 30 ºC but not at 45 ºC. Strains grow at pH 9 as profusely as at pH 7, but are
unable to grow at pH 5; tolerate 5% (w/v) NaCl but not 7%. Strictly aerobic.

Positive results for casein hydrolysis, catalase, gelatinase (weak), nitrate reduction, acid production from: N-acetylglucosamine
(weak) and D-fructose. The other API 50 CHB substrates are not fermented.
Negative results for arginine dihydrolase, aesculin hydrolysis, citrate utilization, H2S production, indole production, lysine
decarboxylase, ONPG, ornithine decarboxylase, oxidase, starch hydrolysis, urease and Voges-Proskauer test.
No substrate is acidified in the API 50 CHB gallery.
No substrate was used as the sole carbon source in the API Biotype 100 kit.
