VARIANTS OF LACTIC ACID BACTERIA USEFUL IN PRODUCING VITAMIN K2 AND THEIR APPLICATIONS TO THE PREPARATION OF FOOD PRODUCTS

摘要

The present invention relates to variants of strains of lactic acid bacteria which produce, under standard fermentation conditions, at least about 1.2 times more vitamin K2 than strains of lactic starter bacteria grown under the same conditions, and the ferments comprising In addition, the present invention relates to a process for obtaining a natural variant having these characteristics.The invention also relates to a process for the preparation of food products, especially fermented products and / or fresh dairy products, enriched vitamin K2, as well as the food products thus obtained.
