ROUTINE TESTS FOR THE DESCRIPTIVE CHART v49-23 



milk, fractionally sterilized at temperatures not over 100° so as not to alter the color of 

 the milk. The growth is mixed with the milk by use of a platinum needle, and the tube 

 is incubated at 37° until coagulation occurs. 



Although the Committee is not prepared to recommend cither 

 method, it is felt that by a combination of the two a good indication 

 of rennet production can be obtained.
