214 PRINCIPLES OF SOIL MICROBIOLOGY 



spores 1 to 2.2 by 0.6 to 1.2^ (1.8 by 0.8/x) ; weak reducing power; diastase is formed; 

 gelatin is liquefied. 



5. Bac. hollandicus A. M. & S., with peritrichic flagellation, is 6 by 0.7 to 0.8^; 

 spores 1.6 X 0.8^; weak reducing power; diastase not formed, gelatin is liquefied. 



6. Bac. carolarum Koch. 



Ulpiani and Cinglani 32 isolated from pigeon manure a bacterium capable of 

 decomposing guanin and guanidin, but not uric acid. 



The chemical processes involved in the transformation of urea, 

 uric and hippuric acids are discussed elsewhere (p. 487).
