Carbon source–dependent transcriptomic regulation and monosaccharide remodeling of exopolysaccharide biosynthesis in Pediococcus pceusentosa LL-07
Carbon source selection alters the transcriptional profile of P. pentosaceus LL-07, affecting the monosaccharide composition, in vitro antioxidant activity, and thermogravimetric properties of its EPSs. These findings connect sugar metabolism to EPS structural changes. They provide a potential strategy to tailor microbial polysaccharides through substrate engineering for applications in functional foods and biotechnology.
