Definition
role held by a material entity when it is added, or planned to be added, to a cell culture during cultivation or production to supply or replenish nutrients
Explanatory Notes
This role applies to additions that are part of a controlled feeding strategy after inoculation. The purpose of nutrient feeds can include sustaining cell growth and viability, preventing nutrient depletion, extending the productive phase, optimizing productivity, or steering metabolic activity. Feeds are often chemically defined solutions and can be single or multicomponent solution containing glucose, amino acids, vitamins, trace elements, and sometimes lipids, but may also be provided as powders or slurries in some settings.
Examples
- role held by concentrated glucose feed pumped to maintain glucose above a target setpoint; role held by a feed solution containing glucose, amino acids, vitamins, trace metals, and lipids added during cultivation to support high cell density and balanced metabolism
Counter-Examples
- role held by IPTG when it is used for induction; role held by glucose already present in the medium
