  • Patent number: 10006067
    Abstract: The invention relates to a method for fermentation production of DHA, in particular a method for producing DHA through solid culture and liquid fermentation of Schizochytrium. The method comprises steps of activation of a strain, preparation of a suspension of the strain, preparation of a primary seed, preparation of a secondary solid seed, enlarging cultivation of the secondary solid seed in a fermentor, collection of cells after fermentation, and extraction of DHA oil. With the fermentation method, the seed preparation method is improved, the seed enlarging technology is simplified, the period of seed culture and fermentation is shortened, and therefore the investment is reduced and the cost is saved; in addition, the solid culture medium is of eutrophy and rich in a plurality of growth factors, and is more beneficial to the growth of the seed; cells are strong in viability and good in synchronism in solid culture medium.

  • Patent number: 8765421
    Abstract: A method for producing coenzyme Q10 by using stock culture from solid phase fermentation. The strain used in this method is Rhodobacter sphaeroides. Strain passaging is carried out by culturing in a slant medium. After steam cooking and air drying, solid medium is subpackaged and sterilized, wherein said solid medium includes solid components and liquid components. The fresh culture of Rhodobacter sphaeroides on the slant medium is added with sterile water, and the resultant bacterial suspension is added into the solid medium, cultured and used as stock culture for primary fermentation. The method of the present invention can enhance the fermentation level of coenzyme Q10, reduce the cascades of fermentation, shorten production cycle, simplify production processes, and lower production cost.
