摘要 |
A method for culturing Bacillus subtilis in such a manner that a vitamin K derivative is accumulated in the largest amount in the cells of the microorganism. A method for the culture of Bacillus subtilis, which comprises culturing Bacillus subtilis and recovering the cells of the microorganism before the vitamin K produced within the cells of the microorganism is released from the cells is disclosed, as well as the cultured product of Bacillus subtilis cultured by this method, a water-soluble vitamin K derivative originating in the cultured product, a food product, beverage, or feed containing the cultured product and/or the water-soluble vitamin K derivative, and a method for extracting vitamin K.
