DESCRIPTION OF SIM 



521 



They were isolated from deep- 

 sea dredgings. 



Bacillus liodermos (Fliigge). 

 Small short rods with rounded 

 ends : actively motile. 



Colonies with irregular outlines 

 float on liquefied gelatine in the 

 form of small white flakes. 



Inoculated in gelatine a greyish 

 growth occurs along the track of the 

 needle, but the medium later be- 

 comes liquefied and a greyish-white 

 flocculent deposit settles at the 

 bottom. 



On potato a smooth shining yel- 

 lowish-white layer spreads quickly 

 over the whole surface, and after 

 some days becomes opaque and 

 slightly wrinkled. 



They occur on potato. 



Bacillus liquefaciens (Eisen- 

 berg). Rods short and thick, with 

 rounded ends. Very motile. 



Colonies round, with smooth 

 edges and slimy centres. Lique- 

 faction follows, and a putrefactive 

 odour is noticed. 



In gelatine they make a funnel- 

 shaped whitish growth along the 

 track of the needle. 



On potato the growth is pale 

 yellow. 



They occur in water. 



Bacillus liquefaciens commu- 

 nis (Sternberg). Rods 1 to 2 p in 

 length, and '7 /x in width : singly 

 and in pair-. 



In the depth of gelatine they 

 produce rapid liquefaction in the 

 track of the needle. 



On potato a wrinkled pinkish 

 layer is formed. 



"They were isolated from the eva- 

 cuations of yellow-fever patients. 



Bacillus " liquefaciens magnus 

 (Liideritz). Rods 3 to C> p in 

 length, -8 to 1-1 p. in width, and 

 filaments. They are anaerobic. 



Colonies develop below the sur- 

 face of the gelatine, and liquefaction 

 extends upwards to the surface. 



The bacilli inoculated in the 

 depth of gelatine cause liquefaction 

 in the lower part of the track of 

 the needle. 



In the depth of agar the colonies 

 have delicate branches. 



They liquefy blood-serui 

 produce a putrefactive odour. 



They occur in earth.

 (Liideritz). -Rmls 2 to M in 

 length, -5 to 7 M in width.

Colonies are white, and li ,

 spherical or almond-shaped. 



In the depth of gelatine isolated 

 colonies appear in th- track < 

 needle, and in the depth of agar 

 there is gas formation. 



They occur in earth.
