et al.,1998 (Proom and Knight ,1950). Old synonym:
Bacillus pantothenticus Proom and Knight, 1950
Gram positive, 0.4-0.7 x 1.2-3.5 μm, motile with peritrichous flagella. May form filaments.  Spores are oval, terminal or subterminal,  
swelling the sporangium. Colonies: 1-4 mm in diameter, low convex, circular and slightly irregular, butyrous, creamy-grey and almost
opaque.
Requires pantothenic acid, amino acids, thiamine and biotin. Maximum growth
temperature is 45-50 ºC; minimum temperature, 15-20 ºC
Grows in anaerobic agar. Can grow in 5% and 10% NaCl. No growth at 5,7 pH.
Isolated from soil.
Unknown.

Positive results for catalase, starch hydrolysis, acid (without gas) production from:
glucose, D-mannose, salicin & trehalose.

Negative results for decomposition of tyrosine, Voges-Proskauer, resistance to
lysozyme, citrate utilization, indole production, arginine dihydrolase, H
2S, acid  
production from: adonitol, dulcitol, erythritol, mannitol, arabinose, xylose & glycogen.

Reduction of nitrate to nitrite & decomposition of casein is variable.
