The present invention discloses a method for promoting B. subtilis to synthesize surfactin based on multi-gene synergy, and belongs to the field of genetic engineering. Firstly, B. subtilis is enabled to obtain the ability to synthesize surfactin by integrant expression of sfp protein derived from a high-yield strain, on this basis, by knocking out genes associated with a competitive pathway, overexpressing genes associated with the surfactin tolerance of B. subtilis, strengthening genes associated with a branched chain fatty acid synthesis pathway or improving the intracellular srfA gene transcription level, the synergy among genes is realized, and systemic metabolic engineering transformation is performed on the B. subtilis, thereby greatly improving the ability of B. subtilis genetically engineered bacteria to synthesize surfactin. Compared with a starting strain B. subtilis 168, the amount of extracellular accumulation of surfactin of the B. subtilis genetically engineered bacteria increases from 0 g/L to 12.8 g/L. The present invention obtains the recombinant B. subtilis with significantly improved ability to synthesize surfactin by multi-gene cooperative transformation of B. subtilis, and has a good application prospect.
