Relationships among bacterial communities on each sample. (a) Hierarchical clustering tree of the bacterial community composition at the OTU level based on Bray-Curtis distances. (b) PCoA plot based on an OTU-based unweighted-Unifrac distance metrics derived from the different treatments. The two PCs (PC1 and PC2) extracted accounted for 46.77% of the total variance. (c) Heat map of mean relative abundances (%) of bacteria in samples
