Polymerization-dependent gut microbiome responses to curdlan β-1,3-glucan and its oligosaccharides.
β-1,3-Glucan is a dietary fiber with microbiome-modulating potential, yet the role of polymerization degree on microbial composition and metabolism remains unclear. Curdlan is an insoluble linear β-1,3-glucan widely used as a food hydrocolloid that provides a model to examine structure-dependent microbiome responses. W...
