Growth studies and measurement of La3+ uptake suggest La3+ storage capability. (a) Growth of wild type (red dashed circles), lutH (white triangles), lutA (blue squares), lutE (gray diamonds), and lutF (black circles) strains grown with limiting succinate (3.75 mM), methanol (125 mM), and 2 μM LaCl3. Data are the average of three biological replicates. Standard deviations between biological replicates were less than ± 0.02. (b) La3+ concentrations (μM) in culture supernatants of lut mutant strains depicted in same color code as in (a). Data depict the average of three biological replicates with error bars showing the standard deviation. One-way analysis of variance (ANOVA) followed by a t-test was used to represent statistical significance. *The p-value is < 0.005.
