Method for extracting coenzyme Q10 from microorganism

The invention discloses a method for extracting coenzyme Q10 from microorganisms, wherein the ultrasonic disintegration is to mix microorganisms with the ability of producing the coenzyme Q10 and an organic solvent in which the coenzyme Q10 is well dissolved according to the mass volume ratio of 1-5 to 10-20, and to obtain the coenzyme Q10 after ultrasonication at a temperature of 0 DEG C, wherein the ultrasonic frequency is between 0.2 and 0.8 and the power is between 300 and 500 watts; and the alkaline splitting method is to extract the coenzyme Q10 from fermentation broth of Rhodobacter sphaeroides. The microorganisms are preferred to be microorganisms of the Rhodobacter sphaeroides. The method for extracting the coenzyme Q10 has the advantages of high efficiency, low pollution, low requirements on apparatuses and equipment, low cost and so on, and is suitable for promotion and application.
