Scale-down models

Definition

Scale-down models are simplified representations of larger biological systems used to study, predict, and optimize the behavior of these systems in metabolic engineering and biotechnology. These models help researchers understand complex biological processes by reducing the system's size and complexity while still maintaining essential features and functionalities. By using scale-down models, scientists can efficiently test hypotheses and make informed decisions about engineering modifications in metabolic pathways or biotechnological applications.
