动物细胞的灌注培养与分批或补料分批培养相比具有若干优点。例如,它们提供更高的生产率和一致的产品质量,并允许稳态操作和更好的细胞生理学控制。然而,限制灌注过程的性能和规模扩大的主要方面之一是需要足够的细胞保留装置。目前用于搅拌灌注生物反应器的装置是连续离心机、切向流膜过滤器、动态过滤器、旋转过滤器、超声和介电泳分离器、重力沉降器以及最近的水力旋流器。这些方法中的每一种的优点和缺点将被讨论。
Perfusion cultures of animal cells have several advantages over batch or fed-batch cultures. They give, for instance, higher productivities and a consistent product quality, and allow steady state operation and better cell physiology control. However, one of the main aspects limiting performance and scale-up of perfusion processes is the need for an adequate cell retention device. The devices currently in use for stirred perfusion bioreactors are continuous centrifuges, tangential flow membrane filters, dynamic filters, spin-filters, ultrasonic and dielectrophoretic separators, gravity settlers and, more recently, hydrocyclones. The advantages and disadvantages of each of these methods will be discussed.
