Abstract
The human gut microbiota plays a critical role in regulating host health and disease, making it a key target for the development of targeted microbial therapies. This review focuses on designer probiotics and synbiotics, which are genetically engineered microorganisms used in combination with prebiotics to modulate the gut microbiota and support personalised health outcomes. Unlike conventional probiotics, these engineered strains are designed to perform specific metabolic or signalling functions, thereby enhancing colonisation efficiency and functional efficacy. The article summarises recent advancements in systems biology, synthetic biology, and omics technologies (including genomics, proteomics, and metabolomics) that facilitate the design and optimisation of next-generation microbial formulations. Their significance lies in enabling precision nutrition and the development of functional foods tailored to individual host requirements. This review also discusses strategies for microbial strain engineering, synbiotic formulation, and the application of high-throughput omics approaches to better understand host-microbe interactions. Furthermore, it highlights applications in managing gut-related disorders and improving food quality. While addressing challenges such as biosafety concerns, regulatory limitations, and environmental implications, the review emphasises the potential of designer probiotics and synbiotics as innovative tools for precision-guided health through dietary interventions. Overall, this emerging field provides a sustainable approach to advancing nutrition and microbiome-based therapies by bridging precision health with food science.
