Manipulation of mll affects growth yield and neodymium bioaccumulation. (A) Growth of ΔmxaF (filled circles) and ΔmxaF/pMLL (empty circles) with 1 μm Nd2O3. Individual data points represent the mean of three replicates and error bars represent SD. (B) Growth of ΔmxaF (filled circles) and ΔmxaF/pMLL (empty circles) with 2 μm NdCl3. Individual data points represent the mean of three replicates and error bars represent SD. (C) Growth yield of ΔmxaF and ΔmxaFΔmll growing with 2 μm NdCl3, 1 μm Nd2O3, or 50 nM NdCl3, with or without 50 nM MLL. Values represent the mean of three replicates and error bars represent SD. (D) Intracellular accumulation of Nd by ΔmxaFΔmll, ΔmxaF, and ΔmxaF/pMLL with 2 μm NdCl3 and 1 μm Nd2O3. Values represent the mean of three replicates and error bars represent SD.
