A growth medium adapted for the growth of a variety of different lactobacilli is provided. The medium is based on milk which is supplemented by at least four free amino acids, at least two ribonucleosides or other ribonulcleotide precursors, and iron. A variety of different Lactobacilli, particularly Lactobacilli belonging to Johnson's group A and B groups, are able to reproduce at rates approximately the same as milk supplemented with yeast extract. This medium when used in the production of dairy products that contain Lactobacilli does not contain the off-flavor of a fermented medium that had been supplemented with yeast extract.
