Strain optimization

Definition

Strain optimization is the process of enhancing microbial strains or cell lines to improve their performance in producing desired compounds, such as pharmaceuticals or biofuels. This involves genetic modifications, metabolic pathway adjustments, and environmental condition changes to maximize yield and efficiency, ultimately leading to more effective drug discovery and development.
