Rods : 0.5 to 1.0 by 7.0 to 35.0 microns, 

 occurring singly and in chains. Non- 

 motile. Gram-positive. 



Gelatin colonies: No growth. 



Beer wort gelatin stab : Beaded to 

 arborescent growth. 



Beer wort agar colonies: Small, gray, 

 raised, filamentous. 



Agar slant : Little or no growth ; better 

 in stab. 



Broth: Good growth in yeast extract. 

 Turbid. 



Litmus milk: Acid. 



Nitrites not produced from nitrates. 



Acid from arabinose, glucose, fructose, 

 galactose, maltose, sucrose, dextrin, 

 rafRnose, trehalose and mannitol and 

 slightly from lactose and starch . No acid 

 from xylose, rhamnose or inulin. Forms 

 1.5 per cent acid in mash. Also forms 

 CO2 and alcohol, lactic, formic and acetic 

 acid. 



The species includes the ordinarily 

 long rod types from spoiled beers. Ap- 

 parently the same variations in regard to 

 sugar fermentation may be found as are 

 noted for similar species. 



Optimum temperature 29° to 33°C. 

 :\Iinimum 11 °C. Maximum 37°C. 



Microaerophilic. 



Source : From sour beer and from dis- 

 tillery yeast. 



Habitat: Probably more widely dis- 

 tributed than indicated by isolations.

 f. Garungsphysiol., 5, 1916, 273; Lacto-
