Identification of the microbiota with known riboflavin-producing activity among annotated OTUs. a Cumulative relative abundance of riboflavin-producing bacterial taxa (predicted from literature and KEGG database search) in oral control tissue and paired AP tissue. Relative gene counts of b RibA, c RibE, and d RibD as inferred from 16S sequence data by PICRUSt in control tissue compared to AP tissue. Wilcoxon matched-pairs signed rank test (two-tailed) was used to assess statistically significant difference between the two groups, p-values are displayed
