Abstract
The present invention relates to a method for improving the heterologous synthesis of a polyketide byand use thereof. The yield of the polyketide heterologously synthesized byis significantly increased by attenuating the expression of seventy-two genes, such as sucC and talB, in a host strain, wherein the highest yield increase rate can reach 60% or more. Currently, erythromycin is the most clear model compound in the study on the biosynthesis of polyketids. The production strain of the present invention enables massive accumulation of 6-deoxyerythronolide (6-dEB), an erythromycin precursor, in the fermentation process, laying the foundation for the industrial production of the heterologous synthesis of erythromycin by
