Summary

The nutritional deficiencies of co-precipitate as a growth medium for a strain of Lactobacillus acidophilus have been studied. Acid production by this organism was insignificant in a medium composed of 4% low-calcium co-precipitate and 5% lactose.

Additions of the amino acids phenylalanine, tyrosine, valine, cysteine and threonine as well as of nicotinic acid, manganese, magnesium and citric acid all increased acid production.

When only half the milk solids of skim-milk powder was replaced by the coprecipitate, fortification with manganese only was required.
