Mycelial biomass concentration (A), iron content in the mycelial biomass (B), iron transfer from culture medium to the mycelial biomass (C), solubilized iron from the mycelial biomass (D), iron availability from the mycelium biomass (E), and overall iron yield (soluble iron amount per liter of culture medium) (F) of basidiomycetes grown in liquid culture medium of malt-extract or sugarcane molasses for 21 days. Malt-extract culture medium: 60.00 mg L⁻¹ nitrogen, 19.14 g L⁻¹ carbohydrate, 0.116 mg L⁻¹ iron, and 260.00 µg L⁻¹ magnesium; sugarcane molasses culture medium: 120.00 mg L⁻¹ nitrogen, 16.72 g L⁻¹ carbohydrate, 91.23 mg L⁻¹ iron, and 903.12 µg L⁻¹ magnesium. Different letters indicate differences among data by Tukey's HSD test (p ≤ 0.05).
