ORDER IV, EUBACTERIALES 



ether, chloroform and benzol; soluble (Hef- 

 feran, op. cit., 1903, 529). Yellow pigment 

 insoluble. 



Distinctive character: Milk becomes 

 blood-red in 12 to 20 days. 



Non-pathogenic for mice (Fuller and 

 Johnson, op. cit., 1899, 609). 



Optimum temperature, between 28° and 

 35° C. 



Aerobic (Fuller and Johnson, loc. cit.). 

 Facultatively anaerobic (Hefferan, op. cit., 

 1903,530). 



Source : Isolated from red milk by Hueppe 

 in Wiesbaden in 1886. Isolated from feces of 

 a child by Baginsky (Cent. f. Bakt., 6, 1889, 

 137). Isolated from Ohio River water by 

 Fuller and Johnson (op. cit., 1899, 609). Iso- 

 lated from Mississippi River water by Hef- 

 feran {op. cit., 1903, 456). Burri and Staub 

 (Landwirtsch. Jahrb. d. Schweiz, 40, 1926, 

 1006) isolated an organism of this type from 

 Emmenthal cheese; they regarded it as 

 closely related to or possibly identical with 

 this species. 



Habitat: Probably widely distributed in 

 nature.
