Zusammenfassung
Perfusion processes have experienced increased popularity in recent years due to their ability to sustain high cell densities and productivities in biopharmaceutical production, offering advantages over traditional batch and fed-batch cultivation methods. The Mobius® Breez microbioreactor significantly reduces experimental effort by downsizing the classical volume of perfusion bioreactors to the mL range and thus represents a valuable tool for process development. However, miniaturization has raised questions regarding comparability with traditional bioreactors in terms of the physical environment, such as hydrodynamic shear stress. Therefore, the maximum hydrodynamic shear stress, cultivation performance, and membrane-wall contact were evaluated to elucidate the system's behavior. Findings reveal two distinct operational conditions, distinguished by the presence or absence of membrane-wall contact, resulting in varying levels of hydrodynamic stress. Conditions lacking membrane contact demonstrate stress levels within safe operating thresholds for CHO cells, while those involving membrane contact exceed these thresholds, potentially leading to cell damage. Through the identification of critical frequencies of membrane motion, this study offers insights for optimizing microbioreactor operation and enhancing overall bioprocess efficiency.
