Fig. 1From: The accumulation of rare-earth yttrium ions by Penicillium sp. ZD28Effects of different concentrations of Y3+ on fungal growth. The concentration of Y3+ in column of a–e were 10, 100, 200, 400 and 800 mg/L, respectively; the line I, II and III contain strains number 1–4, 5–8, 9–11, respectively. The strain number 1 in red circle is the target fungus, identified Penicillium sp. ZD28Back to article page
