  Sreevarshini. S1, Saranya N1*, G. Umamageshwari1 1Department of Biotechnology, Nehru Arts and Science College, Coimbatore, Tamil Nadu, India *Corresponding Author E-mail: [email protected] Abstract: Postbiotics represent a paradigm shift in microbiome-based therapeutics, offering the functional benefits of probiotics without the challenges associated with live microorganism administration. Defined by the International Scientific Association for Probiotics and Prebiotics (ISAPP) as "preparations of inanimate microorganisms and/or their components that confer a health benefit on the host," postbiotics encompass a diverse array of bioactive compounds including cell wall components, metabolites, short-chain fatty acids, bacteriocins, and extracellular vesicles. This review synthesizes current evidence on the mechanisms through which postbiotics modulate host physiology, their therapeutic applications across various disease states, and the challenges and opportunities that lie ahead for clinical translation. Emerging evidence supports their efficacy in gastrointestinal disorders, metabolic diseases, immune modulation, and beyond, while their superior stability, safety profile, and standardization potential position them as attractive candidates for next-generation biotherapeutics. Keywords: Postbiotics, Biotherapeutics, Gut Microbiota Received: Jan. 18, 2026 Revised: Feb. 28, 2026 Accepted: March.

  The present study is primarily limited by its exclusively in vitro the absence of comprehensive metabolomic design and characterisation of the postbiotic compounds. The SCFA detection in this work was of a preliminary nature and not fully validated quantitatively. Additionally, the taxonomic identification based on 16S rRNA gene sequencing may not provide strain-level resolution. The potential influences of age-related variability on the composition of the gut microbiome were not specifically controlled and represent another limitation of this study. Future studies involving whole-genome sequencing, metabolomic profiling, and in vivo validations are therefore necessary to confirm the functional and therapeutic potential of the identified isolates. Notwithstanding these limitations, our study offers important preliminary insights into the functional potential of probiotic isolates derived from a traditionally underexplored population. The integration of culturebased isolation with multi-parameter functional screening provides a useful framework for identifying candidate strains with desirable properties. From a translational perspective, such strains may serve the development of postbiotic-based as a formulations or next-generation probiotics pending rigorous validation.
