Abstract: Spiramycin is a 16-membered ring macrolide antibiotics,and plays an important role in clinical practice. It is produced by S. ambofaciens. Spiramycin is composed of three parts:forosamine,mycaminose and mycarose. This article describes briefly the physicochemical properties and pharmacological effects of the spiramycin,and recent advances on the biosynthetic pathway and the fermentation process. According to biosynthetic pathway of spiramycin,the techniques for increasing its yield,i.e.,adding precursor or beneficial substances to precursor,and direct overexpression of some important genes,were briefly summarized from 3 aspects of the molecular and genetic level,as well as fermentation process,respectively

Key words: spiramycin, biosynthesis, gene-regulation, precursor
