One of the most abundant skin microbes, linked to acne development, becomes problematic when its strains are imbalanced, highlighting the need for targeted treatment strategies.
Researchers created a genome-scale metabolic model (GEM) for the virulent strain CA843 to better understand its behavior in skin environments and validated its predictions against experimental data.
They identified specific biosynthetic pathways in the model related to short-chain fatty acids, discovered the Wood-Werkman cycle's role in propionate production, and suggested potential anti-acne targets using a systematic, model-based approach.
