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.
