all of the sucrose-negative, salicin-negative strains be included 

 in the species B. acidi-lactici in which may be recognized two 

 varieties, the motile B. acidi-lactici var. Gruenthali and the non- 

 motile B. acidi-lactici var. immohili.

THE SUCROSE POSITIVE STRAINS OF THE COLI GROUP 



Of the 93 organisms which fermented sucrose with gas forma- 

 tion, 77 (82.8 per cent) were motile; 84 (90.4 per cent) formed 

 indol; and positive gas reactions were obtained as follows: 

 dulcitol 64 (72.1 per cent); glycerol 56 (60.2 per cent) and sahcin
