【Abstract】 Cytidine is an important antitumor and antiviral drug intermediate. Its synthesis and industrialization process can directly affect the research and production of drug products. The synthesis methods of cytidine are mainly divided into chemical synthesis method and biological method, in which biological method is the hot spot of current research. The common methods are ribonucleic acid hydrolysis, precursor addition fermentation and direct fermentation. Direct fermentation has many advantages, such as high yield, low cost and so on. The core of direct fermentation is to breed stable and high yield strains by modern molecular biotechnology. In this paper, the main methods and pathways of biosynthesis of cytidinewerebrieflysummarized, andthebreedingexamplesofBacillusamylolyticawerereviewed.更多还原
