Overview

Computational modeling demonstrates accurate prediction of multi-phase growth in Staphylococcus aureus and Pseudomonas aeruginosa, suggesting reliable estimation of cellular stress history.

Key Points

To develop a mechanistically inspired geometric growth model using a mean-field approach to predict bacterial growth trajectories across distinct environments without making assumptions about specific intracellular mechanisms.
Formulated a geometry-based population growth model treating bacterial cells as a cascading sequence of biochemical events under a mean-field framework.
Fitted and evaluated the model against existing experimental growth data for Staphylococcus aureus and Pseudomonas aeruginosa cultured in both closed and open environments.
Benchmarked the framework against contemporary phenomenological and mechanistic growth models.
Captured the lag, exponential, and stationary phases observed experimentally without relying on detailed cellular mechanism assumptions.
Extracted model parameters across multiple datasets that reliably reflected the bacterial population's historical exposure to cellular stress.
Demonstrated superior robustness and predictive accuracy compared to contemporary models across varying environmental conditions.
