Definition
planned process that is a part of a cultivation or production process and triggers a defined change in cellular function, pathway activity, production phase, or differentiation state
Explanatory Notes
An induction process is intentionally designed to push the culture into a new physiological or metabolic state. This may include activation or repression of gene expression, initiation of a production phase, promotion of differentiation, or induction of a stress response that enhances productivity. The mechanism of induction can vary and may involve material addition (e.g., IPTG, tetracycline, retinoic acid), material depletion or starvation (e.g., serum withdrawal, nutrient limitation), environmental changes (e.g., temperature shift, pH shift), or physical stimuli (e.g., light pulse for optogenetic activation).
Examples
- IPTG (Isopropyl-Ξ²-D-1-thiogalactopyranoside) addition to induce recombinant protein expression under a lac promoter; Temperature downshift from 37 Β°C to 32 Β°C to initiate production phase
Counter-Examples
- galactose addition to shift glycosylation profile
