Description
Engineered fermentation microbes convert amino‑acid precursors into high‑value flavor compounds under tightly controlled conditions.
Technical
By introducing heterologous enzymes such as phenylalanine ammonia‑lyase or proteases into Lactobacillus, Saccharomyces, and Bacillus strains, the metabolic flux is redirected toward the synthesis of 2‑phenylethanol, vanillin, and umami peptides. The engineered pathways rely on co‑factor regeneration and substrate channeling to achieve yields of 0.3–0.5 g L⁻¹ for aromatics and 10 mg mL⁻¹ for peptides, illustrating the power of synthetic biology in flavor chemistry.
