The effect of sequencing depth on PanPhlAn analysis of the two most abundant kefir species, Lactobacillus kefiranofaciens and Leuconostoc mesenteroides. a The predicted percentage similarity of kefir strains relative to their most closely related reference strain, at each sequencing depth. Grey cells indicate that the species was not classified to the strain level at the specified depth. b Statistical differences in the percentage similarity at 100,000, 1,000,000, and 7,500,000 reads per sample
