Agro-industrial residues, typically viewed as a low-value by-product, have demonstrated significant potential to produce prebiotic oligosaccharides, such as xylo-oligosaccharides (XOS) and cello-oligosaccharides (COS). This study evaluates the effects of XOS and COS, derived from sugarcane bagasse (SB) and corn hulls (CH) through enzymatic hydrolysis, on the modulation of human intestinal microbiota in vitro. S...
