METHOD FOR OBTAINING VARIANTS OF LACTIC ACID BACTERIA USABLE FOR PRODUCING VITAMIN K2 AND APPLICATION TO THE PREPARATION OF FOOD PRODUCTS

摘要

The present invention relates to the production of variants of lactic bacteria stems that produce, under standard fermentation conditions, at least about 1.2 times more K2 vitamin than the starting lactic bacteria stems cultured in the same conditions. The invention further relates to a method for preparing food products, including fermented products and/or fresh diary products, enriched with K2 vitamin, and to the food products thus obtained.
