From: Capturing the diversity of the human gut microbiota through culture-enriched molecular profiling
Culture-enriched molecular profiling detects more OTUs than culture-independent sequencing. a A comparison of the number of OTUs detected by culture-independent and culture-enriched sequencing for each fecal sample. The average number of OTUs detected by each method is shown; error bars represent standard deviation. b Phylogeny of Greengenes 16S rRNA gene sequences to which OTUs were assigned (clustered to 97 % sequence similarity). The branch nodes and three innermost rings are labeled based on detection by culture-independent, culture-enriched, or both methods. The outer ring and background are colored by phyla, as indicated in the legend
