Fluctuations in Intestinal Microbiota Following Ingestion of Natto Powder Containing SONOMONO Spores: Considerations Using a Large-Scale Intestinal Microflora Database.

Improving the intestinal microbiota using probiotics, prebiotics, and synbiotics has attracted attention as a method of disease prevention and treatment. This is the first study to discuss the effects of food intake on the intestinal microbiota using a large Japanese intestinal microbiota database. Here, as a case study, we determined changes in the intestinal microbiota caused by ingestion of a processed natto food containing SONOMONO spores, SONOMONO NATTO POWDER CAPSULES, by analyzing 16S rRNA sequence data generated using next-generation sequencing techniques.
