Biotechnology and Bioengineering, EarlyView.ABSTRACT Maintaining consistent cellular physiology during bioprocess scale‐up or scale‐down is key to developing robust processes. However, the reliability of scale‐down bioreactor systems remains debated. Although the calibration of physiological parameters in mechanistic models across scales has been proposed as a scale‐down strategy, few studies ...
