ULTRA SCALE-DOWN CONCEPTS TO ADDRESS EARLY STAGE PROCESS DEVELOPMENT CHALLENGES IN INTEGRATED CONTINUOUS BIOPROCESSING

摘要

The benefits of continuous bioprocessing, e.g. accelerated process development and scale-up, reduced capital costs, and standardisation, could be achieved through facility automation, universal process architecture, and the alignment of operational structures for the development and manufacturing organisations [1]. Both control strategy and rational design of universal process architecture demand an understanding of the limits and interdependence of these unit operations, and knowledge on how these could be controlled to sustain desired product quality over long periods of time. For example, to effectively implement global process control, which coordinate feed flowrates, will require information as to the impact on product quality and operational efficiency of the range of flowrates on individual process equipment.
