High Diversity in Iron Cycling Microbial Communities in Acidic, Iron-Rich Water of the Pyhäsalmi Mine, Finland

Figure 3

The number of bacterial (bright red – primers P1/P2, dark red – primers 358f/785r) and archaeal (blue) 16S rRNA genes, fungal 5.8S rRNA genes (brown), and the number of bacterial 16S rRNA genes belonging to Leptospirillum (yellow) and Acidithiobacillus (green) mL⁻¹ in the sample water and enrichment cultures. The efficiencies of the qPCR assays (in order from left to right) were 2.01 (slope −3.29), 2.10 (slope −3.08), 1.65 (slope −4.71), 1.88 (slope −3.66), 1.96 (slope −3.2), and 1.77 (slope −4.02).
