(A) Dilution curve of fungal population. This sequencing can cover the vast majority of fungal population information in the samples. (B) Amplicon sequence variants (ASVS) distribution of fungi in each sample. NDaqu and RM share the highest ASV, while Daqu and air share the highest ASV. (C) Venn diagram is used to represent the ASV shared by fungi in the experimental sample, there are 7 ASVS common to all samples. (D) The fungal population diversities of Daqu, RM and environment were evaluated by richness index (Chao1 and observed species), good's coverage index (good's coverage) and diversity index (Shannon and Simpson). The richness and diversity of fungi is the highest in the air and the lowest in Daqu.
