Fig. 2From: Bifidogenic and butyrogenic effects of young barely leaf extract in an in vitro human colonic microbiota modelPCoA of 16S rRNA gene sequences from fecal samples of nine healthy subjects (HS-1–HS-9). The large, medium, and small circles in the PCoA plot represent the microbiota in feces, the corresponding KUHIMM cultures without YBL, and the KUHIMM cultures with 1.5% YBL, respectively. The cultures were sampled at 48 h after fermentation was initiatedBack to article page
