Method for producing reduced coenzyme Q10 by fermentation of recombinant strains

The invention discloses a method for producing reduced coenzyme Q10 by fermentation of recombinant strains, belonging to the technical field of molecular biology. The method comprises the steps of transferring genes for producing the reduced coenzyme Q10 into strains with reduced coenzyme Q10 ratio of more than 70%; using mutagenesis technology to screen strains with reduced coenzyme Q10 ratio of more than 90%; using the strains with the reduced coenzyme Q10 ratio of more than 90% as cultivated strains to produce the reduced coenzyme Q10. The method further improves production capacity of the gene recombinant strains by using high-yield strains built by gene engineering and mutagenesis technology, so that the method can satisfy requirement of the commercial production.
