Spirulina polysaccharide-based prebiotic foods preparations-a promising approach for modulating gut microbiota and improving health

Abstract

Disruptions in the gut microbiota can impede gene expression and metabolic enzyme activity, thereby precipitating the onset of diverse ailments. Spirulina polysaccharides, which are characterized by their high molecular weight and composed of multiple monosaccharides connected by glycosidic bonds, demonstrate notable biological activity. Gut microbiota possesses the ability to break down Spirulina polysaccharides into butyrate, short-chain fatty acids, and other metabolites that can be readily absorbed and utilized by the human body. Furthermore, Spirulina polysaccharides have the capacity to modulate the composition and metabolic products of the gut microbiota, thus fostering general well-being and averting the onset of diseases. This study reviews and summarizes the critically examines and consolidates the significant regulatory impacts of Spirulina polysaccharides on gut microbiota, elucidating their structural attributes and potential mechanisms of operation. These findings offer a valuable point of reference for the subsequent advancement of prebiotic foods preparations based on Spirulina polysaccharides.
