Abstract
The present invention relates to a novel wild-type Lactococcus lactis subsp. cremoris bacteria strain with increased vitamin K2 production and mutants and variants thereof and methods for preparation of a fermented food or feed product enriched in vitamin K2 and a vitamin K enriched edible product for amelioration and/or prevention of vitamin K deficiency. The present invention also relates to the fermented food or feed product and the edible product obtainable by the methods herein and to the wild-type Lactococcus lactis subsp. cremoris bacteria strain for use in treatment and/or prevention of vitamin K deficiency in a mammal, such as a human.
Claims11
An isolated lactic acid bacteria strain, wherein the lactic acid bacteria strain is Lactococcus lactis subsp. cremoris strain CHCC12675 that was deposited with the Deutsche Sammlung von Mikroorganismen und Zellkulturen under accession No. DSM 23589 or a strain derived therefrom having all identifying characteristics of said Lactococcus lactis subsp. cremoris strain CHCC12675.
