Integrated bioprocesses have been developed to optimise yield and cost-effectiveness of production of low and high molecular weight molecules. Low molecular weight products are removed from the cultivation medium with in situ extraction, in situ adsorption or crystallisation to avoid product inhibition. One-pot processes are being developed to replace two-stage reactions. Recent developments in the integrated purification of high molecular weight products focus mainly on the integration of solid/liquid separation and initial product recovery such as expanded bed adsorption or extraction in aqueous two-phase systems. Additionally, new approaches for a more efficient processing of inclusion bodies have been developed.
已开发出综合生物工艺,以优化低分子量和高分子量分子生产的产量和成本效益。通过原位萃取、原位吸附或结晶从培养基中去除低分子量产物,以避免产物抑制。正在开发一锅法工艺以取代两步反应。高分子量产物综合纯化的最新进展主要集中在固液分离和初始产物回收的整合,如扩张床吸附或水相两相系统中的萃取。此外,还开发了更有效处理包涵体的新方法。
