Eighty-eight strains of microorganisms were isolated from soils collected in northern and southern Chile, and 10 fungi which showed the highest solubilizing action upon the iron in granodiorite were then selected. These fungi were incubated with the following iron-containing minerals: augite, hornblende, biotite, magnetite, hematite, and the igneous rock granodiorite. The solubility of iron in these minerals depended on their nature, crystalline structure, the concentration of metabolic products, or all three. Complex formation could be the mechanism involved, as a strong cation-exchange resin was not able to extract Fe from culture solutions. This conclusion is also confirmed by the R(F) values obtained by thin-layer chromatography of iron-containing culture solutions.
从智利北部和南部采集的土壤中分离出88株微生物，然后挑选出10株对花岗闪长岩中的铁具有最高溶解作用的真菌。将这些真菌与以下含铁矿物一起培养：普通辉石、角闪石、黑云母、磁铁矿、赤铁矿和火成岩花岗闪长岩。这些矿物中铁的溶解度取决于它们的性质、晶体结构、代谢产物的浓度，或者这三者的综合作用。由于强阳离子交换树脂无法从培养液中提取铁，因此可能涉及络合物形成机制。含铁培养液的薄层色谱法获得的R(F)值也证实了这一结论。
