Mushrooms supplementation with iron (Fe) is usually limited, and therefore it would be beneficial to search for other vital elements able to improve the process. The aim of this study was to verify a possible interaction between Fe and calcium (Ca) to estimate the role of the addition of the latter metal to stimulate Fe accumulation in . Additionally, an analysis of phenolic compounds and low molecular weight organic acids (LMWOAs) was performed. The increase of Fe concentration in the substrate caused a significantly higher accumulation of this metal in . The addition of Ca (5 or 10 mM) stimulated Fe accumulation, just as Fe concentration in the substrate stimulated Ca accumulation, which pointed to a synergism between these metals. The obtained results show that the presence of Fe in the substrate may also promote K, Mg, Mn, Na, P, and S accumulation. In contrast, the addition of Ca stimulates and/or inhibits their content in fruit bodies. The phenolic and organic acids profile was poor. Only gallic, 4-hydroxybenzoic, sinapic and syringic acids (phenolics), as well as citric and succinic acids (LMWOAs), were quantified in some combinations in fruiting bodies.
铁（Fe）对蘑菇的补充通常有限，因此寻找其他能够改善这一过程的重要元素将是有益的。本研究的目的是验证铁与钙（Ca）之间可能的相互作用，以评估添加后一种金属对刺激铁在……中积累的作用。此外，还对酚类化合物和低分子量有机酸（LMWOAs）进行了分析。基质中铁浓度的增加导致该金属在……中的积累显著更高。添加钙（5或10 mM）刺激了铁的积累，正如基质中的铁浓度刺激了钙的积累一样，这表明这些金属之间存在协同作用。所得结果表明，基质中铁的存在也可能促进钾、镁、锰、钠、磷和硫的积累。相反，添加钙会刺激和/或抑制它们在子实体中的含量。酚类和有机酸谱较简单。在子实体的某些组合中，仅对没食子酸、4-羟基苯甲酸、芥子酸和丁香酸（酚类）以及柠檬酸和琥珀酸（LMWOAs）进行了定量分析。
