doi:10.13304/j.nykjdb.2022.1020

Abstract

Abstract:

Surfactin is a kind of lipopeptide produced by the secondary metabolism of microorganisms of Bacillus， which has a variety of biological activities with a broad application prospect in many fields such as food， medicine， daily chemical， oil extraction and biological defense. However， the low production efficiency and high production cost of natural strains of Bacillus sp. have severely limited the practical application of surfactin. The structural properties， application effects and regulation of the microbial surfactin on synthesis pathway were briefly described. Several strategies for increasing the yield of microbial surfactin were emphatically reviewed， and the prospects of its efficient production and application was also prospected.

Key words: surfactin, high efficiency synthesis, genetic engineering, rational design
