Fig. 3From: The accumulation of rare-earth yttrium ions by Penicillium sp. ZD28Effects of different concentrations of Y3+ on the morphology of Penicillium sp. ZD28. a–d are the mycelium pellet morphologies of Penicillium sp. ZD28 under the culture conditions with different concentrations of Y3+ for 3 days. a-1/2, b-1/2, c-1/2 and d-1/2 denote micromorphologies of Penicillium sp. ZD28 cultured with different concentrations of Y3+, scale bar 10 μm. The concentrations of Y3+ added according to the a/-1/-2, b/-1/-2, c/-1/-2, d/-1/-2, were 0, 73.71, 461.57, 580.67 μM respectively.Back to article page
