    摘要: The invention concerns mutant L. bulgaricus strains bearing a nonsense mutation, in at least one of the sequences coding for the lactose operon, and free from β-galactosidase activity, and lactic starters comprising these strains. The strains and starters can be used to obtain fermented milk products from glucose-added milk.
