a–c Optical and d–f confocal microscopy images of a, d T2, b, e T4, and c, f T6. Scale bars correspond to 20 µm. Confocal images are overlay images of red and green excitation. Pheroids fluoresce red by association with Nile red. Green spots in d are most probably an artifact from background noise. Arrows highlight particulate agglomerates, namely ferric precipitates for T4 and FePO4 for T6
