Isolation of viral RNA from stool using the QIAamp Viral RNA - Qiagen Remember to save RNA flow through and ensure all sample has passed through the filter plate. The non-phylogenetic metric (i.e., BrayCurtis dissimilarity distance) was calculated for fungi due to the inapplicability of phylogenetic-based metrics (i.e., Weighted/Unweighted UniFrac distance) for ITS1 sequence analysis (Halwachs et al., 2017). However, since fungi form a marginal community in fecal samples, the capability of recovering fungal DNA seems to be an advantage in fecal mycobiome research. Front. During E. faecalis DNA detection, a positive signal was occasionally captured in one of the baseline controls real-time PCR duplicates (once in both, n = 5/15) across methods, with values lower than 1 copy (Supplementary Table S1). Use of the single human stool sample was intended to avoid the effect of inter-individual variability observed elsewhere (Huseyin et al., 2017). These reads (range 7112483383 per method; range 2093830270 per replicate) were distributed into 60 bacterial taxa assigned at genus level (Supplementary Table S3). The speciesrichness and diversity analysis, as well as the compositional analysis were performed among four treatment groups. For both species, the IHMS and ZR methods provided the highest DNA yields consistently (Figures 2B,C). Three independent sets of DNA extraction were performed (Figure 1), and all experimental samples were processed in triplicates for the reproducibility evaluation.
