The ability of mycelia to accumulate bioelements was demonstrated in an experiment in which the world\-renowned fruiting bodies and mycelia from in vitro cultures of Pleurotus citrinopileatus, Pleurotus djamor and Pleurotus pulmonarius were used. The research undertaken in the study was aimed at determining the effect of the addition of inorganic Mg and Zn salts to the culture media on the growth of biomass, as well as the degree of their accumulation. The bioavailability of selected metals \(Mg, Zn\) and ions \(Cl\-, SO42\-\) from the obtained enriched biomass was determined for the first time by extraction of freeze\-dried mycelium in artificial digestive juices. As an addition to the culture media, the following salts were used\: ZnSO4 · 7H2O, ZnCl2, MgSO4 · 7H2O and MgCl2 · 6H2O. The content of Mg and Zn as well as organic compounds \(phenolic compounds, indole compounds, amino acids\) was determined in the obtained material. It has been shown that enrichment of the substrates causes an increase in biomass growth by 30% and an increase in the accumulation of bioelements. The addition of the salts selected for the study also influenced the content of biologically active organic compounds, including indole compounds. In another experiment, indole compounds were also determined using the RP\-HPLC"]
