2.6 | Prediction of microbiome functions by using bioinformatics analysis
We predicted the gut microbiome functions by using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) to elucidate the physiological features and metabolism capability during the process of dietary conversion. To compare the functional categories of microbiota among the four groups (HE, FI, OM and CA) by PICRUSt analyses, functional profile heatmaps based on 423 categories (KEGG level-3) were constructed, which showed marked differences among feeding habits.
