Gram positive, 0.5-1.0 x 2.0-3.0 µm, motile bacilli. Spores are ellipsoidal, subterminal or terminal, swelling the sporangium.
Non-pigmented, smooth, translucent, circular, 1-2 mm diameter colonies. Maximum temperature 45 ºC; minimum temperature 20 ºC,
optimum 28 ºC. Grow in anaerobic agar. Growth in 5% NaCl is variable. Not growing in 10% NaCl. Not growing at 5.7 pH.
Isolated from human feces and dead honeybees larvae. Resistant to 0.001% lysozyme.
Uncertain pathogenicity. Possible implication in Europeean foulbrood as an associated germ.

Similarity with Paenibacillus alvei.
Decomposes thiamine actively.

Positive results for catalase, hydrolysis of starch, indole production,reduction of nitrate
to nitrite, decomposition of casein, decomposition of tyrosine, acid production from:
D-galactose, glucose, lactose, maltose, saccharose, trehalose

Negative results for arginine dihydrolase, lysine decarboxylase, ornithine
decarboxylase, hydrolysis of urea, Voges-Proskauer test, citrate utilization & acid
production from xylose.

Variable results for acid production from: arabinose, mannitol & sorbitol.
