Fig. 4From: Pre-digest of unprotected DNA by Benzonase improves the representation of living skin bacteria and efficiently depletes host DNAChanges of OTU abundance in mock community samples upon serial dilutions. Relative OTU abundance obtained from amplified 16S rRNA gene sequencing from mock communities processed by a BDA or b after NDA extraction decreased for most mock community strains but increased for S. epidermidis. p values were calculated using Wilcoxon-Mann-Whitney test. * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001Back to article page
