The Nutritional Requirements of Lactic Streptococci Isolated from Starter Cultures. I. Growth in a Synthetic Medium

Abstract
The use of reconstituted nonfat milk solids for the growth of lactic cultures has provided greater uniformity in composition of culture medium than is true of selected whole milk or skimmilk ( Yet day to day variations in the rate of growth of such cultures still are encountered. Cultures also frequently show a gradual loss in activity, which suggests some shift in the nutritional requirement of strains comprising the culture. Another possibility is that even highgrade fresh or reconstituted milk may be deficient in some nutrients essential for active growth of some organisms.
