Disposable bioreactor for cell culture using wave-induced agitation

Area of Science:

• Biotechnology
• Cell Biology
• Bioprocess Engineering

Background:

• Traditional cell culture systems face challenges in scalability, cost, and operational complexity.
• Existing bioreactors often require extensive cleaning, sterilization, and specialized infrastructure.

Purpose of the Study:

• To introduce a novel disposable bioreactor system utilizing wave agitation for versatile cell cultivation.
• To demonstrate the system's efficacy in supporting various cell types and applications, including research and Good Manufacturing Practice (GMP).

Main Methods:

• Wave agitation induced by a rocking motion for cell suspension and nutrient distribution.
• Disposable bioreactor design eliminating the need for cleaning and sterilization.
• Simple scale-up demonstrated up to 100 L culture volume.

Main Results:

• Achieved efficient nutrient distribution, off-bottom suspension, and excellent oxygen transfer without damaging shear stress.
• Successfully cultivated recombinant NS0 cells, human 293 cells for adenovirus production, Sf9 insect cells, and human 293 cells on microcarriers.
• Demonstrated suitability for suspension, anchorage-dependent cultures, and virus production.

Conclusions:

• The novel wave-agitated bioreactor offers a cost-effective, scalable, and versatile solution for laboratory and pilot-scale cell cultivation.
• Its disposable nature and simplified operation reduce operational burdens and expenses.
• The system is suitable for diverse research and GMP applications, including cell-based therapies and biologics manufacturing.
