摘要:
分析比较了3种不同微载体悬浮培养工艺——分批换液式、消化传代放大式、循环灌注培养式对Marc-145细胞微载体培养效能及生理代谢的特点及差异,并实现了从5 L至60 L反应器放大过程的PRRSV实际增殖应用。结果表明,在5 L动物细胞反应器中使用相同的微载体用量6 g/L,分批换液式培养和消化传代放大式培养仅获得27×105~28×105 cells/mL的细胞密度,低于循环灌注培养式的培养能力(59.4×105 cells/mL)。根据这3种不同培养工艺的特点,设计并实施了可应用于实际生产的工艺流程,即Marc-145种子细胞以循环灌注培养方式在5 L反应器中完成初级培养,经消化传代工艺,将种子细胞放大接种于60 L反应器中进行分批换液式的二级培养,用于PRRSV的大规模增殖,结果显示PRRSV增殖滴度可达到108.3TCID50/mL。该过程成功地模拟了Marc-145细胞在工业级水平上的放大培养操作工艺,其放大倍数达到1 ∶3的传代系数,具备实际应用价值。
