Definition
plan specification that prescribes how one or more feeding processes are to be executed during a cell culture process, including scheduling and amounts or rates, and any specified triggering conditions
Explanatory Notes
A feeding strategy specifies how feeding processes are to be executed, rather than performing them. It defines scheduling and frequency and may also specify decision rules that determine feed additions, such as fixed pre-set schedules, condition-based triggers based on process measurements, or model-based rules. As a plan specification, it serves as a template guiding execution of one or more feeding processes. Feeding strategies are commonly used to maintain favorable culture conditions, sustain cell growth, and support or optimize product accumulation.
Examples
- periodic bolus feeding strategy for CHO fed-batch cultures; dual-feed strategy combining separate carbohydrate and amino acid/vitamin feeds in CHO cultivation; exponential feeding strategy maintaining a defined specific growth rate in E. coli fed-batch process; model-predictive feeding strategy controlling nutrient supply in CHO perfusion culture
