Metagenomic bacterial functional predications analyzed by Phylogentic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt2). (A) Clusters of Orthologous Groups of proteins (COG) function classification. (B) Principal component analysis (PCA) plot of bacteria metabolic functions. (C) Bar plot of metabolic pathways at level 1. (D) Bar plot of Kyoto Encyclopedia of Genes and Genomes (KEGG) ortholog functional predictions at Level 2. (E) Heatmap of the significantly different microbial functions at level 3. All the values contained 6 repetitions. BA40 = Bacillus amyloliquefaciens 40.
