Multiple E. coli cultivations, producing recombinant proteins, lead to the formation of inclusion bodies (IBs). IBs historically were considered as nondesired by-products, due to their time- and cost-intensive purification. Nowadays, many obstacles in IB processing can be overcome. As a consequence, several industrial processes with E. coli favor IB formation over soluble production options due to the high space time yields obtained. Within this chapter, we discuss the state-of-the art biopharmaceutical IB process, review its challenges, highlight the recent developments and perspectives, and also propose alternative solutions, compared to the state-of-the art processing.
多次大肠杆菌培养生产重组蛋白会导致包涵体(IB)的形成。由于包涵体的纯化既耗时又昂贵,因此历史上它们被认为是不受欢迎的副产物。如今,许多包涵体处理方面的障碍都已被克服。因此,由于获得的高时空产率,许多采用大肠杆菌的工业生产过程更倾向于形成包涵体,而不是选择可溶表达产物。在本章中,我们讨论了最先进的生物制药包涵体工艺,回顾了其面临的挑战,强调了最近的发展和前景,并与最先进的工艺相比提出了替代解决方案。
