High-Throughput 16 S rRNA Gene Sequencing Reveals Bacterial Diversity of Infant Formula Production Line Samples in Spring and Summer

Figure 2

Heatmaps of bacterial operational taxonomic unit (OTU) abundance at the phylum level and genus level in spring (a) and (e), respectively, and summer (b) and (f), respectively; red indicates higher relative abundance. Relative abundance of bacterial species at the phylum and genus levels in spring (c) and (g), respectively, and summer (d) and (h), respectively. The diagrams show the mean relative abundance of top 10 phyla and top 30 genera in each sample.
