  • Patent number: 10982242
    Abstract: The present invention relates to an optimized fermentation process of coenzyme Q10, particularly to a fermentation process of coenzyme Q10 via flow feeding based on cooperative control of changes of online oxygen consumption rate and conductivity. During the fermentation process of coenzyme Q10 production strains, the oxygen consumption rate is controlled between 30-150 mmol/L·h and the conductivity is maintained between 3.0-30.0 ms/cm via flow feeding, so as to facilitate strain growth and the start of coenzyme Q10 synthesis and accumulation. The present invention can substantially increase output of coenzyme Q10 and greatly reduce the production cost with simple process control and strong operability, thus being applicable to large-scale industrial production.

  • Patent number: 10774350
    Abstract: The present application relates to a method for fermentative production of oxidized coenzyme Q10 and high-content oxidized coenzyme Q10 prepared therefrom. For the method for fermentative production of oxidized coenzyme Q10, in a fermentation process of a production strain, the oxidation-reduction potential (ORP) of a fermentation broth is controlled to be ?50 to 300 Mv, and preferably the oxidation-reduction potential (ORP) of the fermentation broth is controlled to be 50 to 200 mV. By controlling the ORP of the fermentation broth, the method for fermentative production of oxidized coenzyme Q10 enables the oxidized coenzyme Q10 content in the coenzyme Q10 produced by microorganisms to reach 96% or more, and the product is substantially composed of a single component, which makes post-treatment more convenient.
