445iron(III) oxyhydroxideTEMDuring fungus-mineral cultivation, transmission electron microscopy (TEM) revealed that the mineral grains (from the initial hematite particles) experienced an 8-fold size reduction, giving rise to a high-density distribution (3,000–6,000 per μm−2; Figure 1A) of ∼3-nm-sized nanoparticles in the aggregates within 48 h.0.120
