Microbial diversity analysis of the 16S rRNA gene sequencing reads

Sample No. of reads Average read length (bp) No. of detected OTUs Average No. of observed species Average Shannon diversity index
H1 current method 8602 530 696 ∼611 6.346
H2 current method 6323 530 497 ∼635 6.852
H1 method A 16,640 530 870 ∼515 5.795
H2 method A 22,697 530 844 ∼496 5.245

Note: H1 and H2 represent metagenomic DNA isolated from fresh human feces of healthy individuals. OTU, operational taxonomic unit.
