Abstract
ABSTRACT
Synthetic biology is expanding from single‐species engineering toward the design of synthetic microbial consortia capable of distributed metabolism, coordinated behavior, and enhanced functional robustness. However, engineering frameworks derived from intracellular genetic circuits remain insufficient to capture the ecological, temporal, and spatial dynamics that govern multispecies systems. Here, a symphony‐inspired systems‐engineering framework is presented for multimicrobial synthetic biology, organizing consortium design across four application‐dependent coordination layers: communication, temporal regulation, ecological structuring, and predictive modeling. Building on this framework, a modular engineering blueprint is proposed to guide the rational selection and integration of coordination layers according to engineering objectives, translating systems‐level principles into operational strategies for the construction, stabilization, and optimization of synthetic microbial consortia. The manuscript integrates advances in interspecies signaling, oscillatory control, synthetic ecology, hybrid modeling, and real‐time monitoring while addressing constraints including metabolite transport, population drift, parameter uncertainty, and process‐scale implementation. The proposed framework is modular rather than prescriptive, allowing different coordination layers to be deployed according to application requirements and environmental complexity. By repositioning multimicrobial engineering as a problem of coordinated systems design rather than isolated genetic control, this Perspective provides a structured foundation for the development of synthetic microbial communities across industrial, environmental, and therapeutic applications.
