PRODUCTION OF ACID IN LACTOSE UROTII AND INIIIBITIVE POWERS OF THE LACTIC ACID 

 PRODUCED RY DIFFERENT ORGANISMS CONTRASTED. 



b c 



CURVE 2. 



Acidity curve shows minimum acidity producing total inhibition. 

 Time curve shows minimum hours recorded for iuliibition to talve place. 

 *=One typhoid colony found at the time recorded above. 

 a.:=Bact. lactis acidi (from starter), 

 b = Bad. lactis acidi, No. 2. 

 c^=Bact. lactis acidi, (from sour milk). 

 d =: Bact. buloaricum. 

 e = Bact. lactis acidi, 5?, B2. 



Conclusion: The time required for inhibition to take place is in inverse propor- 

 tion to the minimum acidity producing inhibition.
