differ widely. These differences may be due to the influence of the 
salts on the enzymes produced in the different media. Sodium 
chloride is least toxic in glucose, starch and peptone, the limit 
concentration being approximately the same in these three media. 
It is more toxic in saccharose than in lactose and more toxic in 
lactose than in glucose, starch or peptone. The average of the 
limit concentrations in the different media is .62 molar. When all 
of the media are thus taken into consideration we see that sodium 
chloride is much more toxic than potassium chloride.
