Fig. 5

Network interactions revealed relationships between microbial and geochemical factors with a threshold of 0.65 for spearman’s coefficient and 0.0001 for P-value. Purple lines indicated positive correlations with electron donors. Gray lines indicated positive correlations with electron acceptors. Circles: Archaeal OTUs; Diamonds: Bacterial OTUs; Triangles: Geochemical factors. The numbers representing generated OTU IDs were shown in Additional file 4: Table S3
