    摘要:

    头孢菌素C由丝状真菌顶头孢霉产生,属于β-内酰胺类抗生素。其经改造后的7-氨基头孢烷酸是头孢类抗生素的重要中间体。头孢类抗生素在国内外抗生素市场中占有巨大的份额,是临床上的主要抗感染药物。随着分子生物学的发展,头孢菌素C的生物合成途径已基本阐明。为提高头孢菌素C的产量和降低生产成本,越来越多的研究者开始关注其较为精细、复杂的调控机制。本文重点对头孢菌素C生物合成及其调控机制的最新进展进行了简述,希望为今后头孢菌素C生产菌株的菌种改造和传统产业的升级换代提供一定的借鉴。

    Abstract:

    The beta-lactam antibiotic cephalosporin C is produced industrially by Acremonium chrysogenum. Its derivative 7-aminocephalosporanic acid (7-ACA) is the intermediate of most chemical modification cephalosporins that are the most frequently used antibiotics for the therapy of infectious diseases. Due to its importance, the biosynthetic pathway of cephalosporin C has been elucidated in Acremonium chrysogenum. To improve the yield of cephalosporin C and reduce the cost of production, recent studies have been focused on the sophisticated regulation of cephalosporin C biosynthesis. In this review, recent advances in cephalosporin C biosynthesis and regulation are summarized.
