Abstract
Consumption of chitooligosaccharides (COS) prevents intestinal microecological disorder. The mechanisms for the effects of different COS on the gut microbiota are currently unclear. This study examined the impact of COS with different degrees of polymerization (DPs) on the gut microbial community and metabolic profile. COS significantly promoted the growth of Bacteroidetes, and inhibited that of Proteobacteria, which were significantly correlated with DPs. COS3 and COS2 enriched the butyrate production in microbial communities composed of Clostridium and Parabacteroides. Microbial communities enriched by DPs 4-6 COS displayed increased diversity in differential metabolite function. Several biomarkers were distinguished significantly, including unsaturated fatty acids, bile acids, indoles and amines, which are mainly related to processes such as fatty acid synthesis and decomposition, bile acid modification, and tryptophan metabolism. The results display the relationship among COS structure-gut microbes-metabolomics, providing a new perspective for COS as a functional food to improve intestinal health.
