This article explores the integration of physical outputs from bioreactor geometries into structured kinetic models to accurately predict cell growth, metabolism, and product formation rates.

Metabolic Flux Analysis (MFA) is a computational technique used to determine the optimal distribution of metabolic fluxes ($\mathbf{v}$) within a biochemical network. By solving the steady-state equation $\mathbf{S} \cdot \mathbf{v} = 0$ and incorporating experimental constraints, MFA identifies metabolic bottlenecks and guides strain engineering efforts.
