 border ; becoming sunken in the liquefied gelatin ; border filamentous ; 

 odor cheesy.

 scopically, dark gray and granular in the interior ; border filamentous — 

 floccose. 



Potato. Growth yellowish gray, soft, flat ; border indented.

 tin liquefied more slowly than B. subtilis ; a membrane on the surface of 

 the liquefied gelatin. 



Gelatin colonies. Like B. subtilis. 



Agar slant. Growth creamy white. 



Potato. Growth dry, yellowish.
