Figure 3.

Growth of A. fumigatus mutant strain ΔsidA/ΔftrA after 48 h incubation at 37 °C on iron‐depleted Aspergillus minimal medium containing different iron-fluorophore conjugates at increasing concentrations (from right to left 0.1; 1; 10; 50 µM). Whitish mycelia result from hyphal growth, while green colouring reflects the formation of conidia. The bottom row shows growth without siderophores demonstrating that this mutant strain is not able to grow without usable siderophores. Data of [Fe]DAFC-Cy5 from reference¹⁸.
