Gut microbiota composition in healthy Japanese before and after fermented milk intake
This project involves a randomized placebo-controlled double-blind parallel-group comparison trial to investigate the influence of Bifidobacterium longum BB536 on gut microbiota and fecal metabolites. Fecal samples from 34 healthy Japanese subjects were analyzed by high-throughput sequencing of amplicons derived from the V3-V4 region of the 16S rRNA gene.
