Milk. Slightly acid, coagulated slowly or not at all. Nitrates reduced to 



nitrites. 

 Habitat. Water.

206. B. vacuolosis Steinberg 



Manual, 1892, 717. 



Morphology. Bacilli i.o: 1.5-5 filaments; ends rounded.

the surface. 



Agar slant. Growth creamy white. 

 Potato. Growth thin, creamy white.
