Fermentation’s microbial metabolism preserves food while transforming its bioactive components, synthesizing health-promoting metabolites, including vitamins, bioactive peptides, antioxidants, and short-chain fatty acids. This review article examines how fermentation utilizes microbial populations to enhance food quality and confer health benefits. We begin by examining the fundamental role of microbes in fermentation, emphasizing essential microorganisms such as lactic acid bacteria, yeast, and mold, which are responsible for the biochemical changes that enhance the quality of fermented foods. These microbes not only enhance flavor, texture, and shelf life but also contribute to improved gut health, regulate the immune system, and reduce inflammation by producing probiotics and other bioactive compounds. The review discusses the emerging applications of fermentation in developing functional foods, emphasizing the growing body of evidence that fermented products can help prevent and manage chronic diseases, including gastrointestinal disorders, cardiovascular disease, and metabolic syndrome. Particular emphasis is placed on how microbial fermentation can enhance the bioavailability of key elements, such as B vitamins and minerals, while degrading anti-nutritional substances like phytates and oxalates, making fermented foods extremely beneficial to a wide range of individuals. In conclusion, this review emphasizes the underutilized potential of microbial metabolism in food fermentation as a valuable tool for improving human health. Researchers and the food industry can design nutrient-dense, functional foods that fulfill customers’ desire for healthier alternatives while simultaneously contributing to global food system sustainability.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8279,"journal":{"name":"Archives of Microbiology","volume":"207 9","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metabolic profiling and multivariate analysis further revealed significant metabolic shifts under co-cultivation, highlighting the strong influence of VOCs on microbial metabolism. In co-culture, <i>P. megaterium</i> showed increased secretion of amino acids (e.g. proline, valine) nucleobases (e.g. thymine) and secondary metabolites (macrolactins, bacilliskamide A, oxydifficidin), suggesting VOC-driven activation. In contrast, <i>B. licheniformis</i> downregulated secondary metabolite secretion, indicating a trade-off favoring intracellular metabolite retention. Key adaptive response involved metabolic routes related to amino acid use and nitrogen recycling, including pathways for lysine and arginine breakdown, which support energy generation and cellular protection.

Advanced technologies are crucial in improving the efficiency of the entire production chain. Enzymatic hydrolysis has emerged as an innovative method, employing enzymes to break down starch into fermentable sugars. This approach is more precise and efficient compared to traditional acid or heat-based methods. Simultaneous Saccharification and Fermentation (SSF) is another advanced technique that combines fermentation and enzymatic hydrolysis, streamlining production and lowering overall costs. Innovations in genetic engineering, particularly the CRISPR/Cas9 system and strain improvement, have significantly enhanced fermentation efficiency, substrate tolerance, and resistance to inhibitors, resulting in higher yields and greater process robustness. This approach aligns with the circular bio-economy principle, where waste streams and by-products are efficiently utilised. The emergence of integrated biorefineries supports circular bioeconomy principles by enabling the co-production of bioethanol and value-added by-products, maximizing resource utilization and minimizing waste.
