Visualization of La3+ storage. TEM of ultrathin sections of wild-type cells harvested at OD600 of ~ 0.6 after growth with 3.75 mM succinate and 125 mM methanol containing (a, b) and lacking (e, f) 20 µM La3+. (c, g) Elemental analysis of electron dense deposits from cells grown with (c) and without (g) La3+. (d) High-resolution transmission electron microscopy analysis of the wild-type strain shows an atomic lattice structure in electron-dense areas suggesting that La3+ is embedded in cytoplasmic crystals.
