B. patati/pIiOSHDi B, and B. enteritidus. These cultures were carried on 

 stock agar and transferred every twenty-four hours till ready for use. 



Inoculations were made in duplicate tubes with a straight platinvim 

 wire, inoculating the surface of the slant first and then making a stab 

 in the butt from the bottom of the slant to the bottom of the tube. In 

 reading the tubes the slant and stab were read separately. The stab 

 gave the acid production under anaerobic conditions while the slant 

 gave the acid change under aerobic conditions. 



All tubes were incubated at 37° C. for 24 hours. 



The following tables give the results obtained.
