The differences of microbes composition between YX-p1 and P (a for bacteria, c for fungi), or P, R, F, and M (b for bacteria, d for fungi) using venn analyses. Venn diagram was used to count the number of common and unique species (such as OTU) in multiple groups or samples, and it could show the similarity and overlap of species in different samples intuitively.
