“…The content of selected macronutrients (Ca, Mg, P, K) and micronutrients (Na, Fe, Zn, Mn) was analyzed. Comparing our results of the selected substances with the results of the study by Zakil et al [ 32 ], we found out that a significantly higher concentration of Ca, Fe and Mn was observed in P. ostreatus samples from Zakil et al [ 32 ]. On the other hand, it was also found out that in our analyzed samples there was a higher content of Mg, K, Na and Zn than in the monitored samples from Zakil et al [ 32 ].…”

On the other hand, it was also found out that in our analyzed samples there was a higher content of Mg, K, Na and Zn than in the monitored samples from Zakil et al [ 32 ]. The authors of Regula et al [ 33 ], however, in their study, grew fruiting bodies on the same substrate as in our study (wheat straw), and they reported related concentrations of metallic elements.…”

“…In many scientific papers it is written that many fungi can absorb certain metals and metalloids from their substrate into their fruiting bodies in high concentrations [ 29 , 30 , 31 ]. Zakil et al [ 32 ], in their study, had 5 different substrate combinations with various biomass ratios which were used for cultivation of P. ostreatus . As a substrate for cultivation of P. ostreatus was used oil palm empty fruit bunch, oil palm press fiber, oil palm frond, sugarcane bagasse and corn cob.…”

“…In our research, it was detected in range concentration of Mg in the stipe from 880 mg kg −1 to 2400 mg kg −1 and in the cap the range of Mg concentration from 1400 mg kg −1 to 2400 mg kg −1 . The concentration of Mg in the samples of P. ostreatus in the study by Zakil et al [ 32 ] ranged from 270 mg kg −1 to 1140 mg kg −1 . The research done by Włodarczyk et al [ 43 ] found that addition of inorganic Zn and Mg salts into the media resulted in the increase of the production biomass by 30% and in the increase of bioaccumulation of the inorganic salts.…”

“…In the research by Zakil at al. [ 32 ] it was mentioned that only in one type of substrate was detected the content of Na in P. ostreatus and its content was 67 mg kg −1 . When comparing the results with previously mentioned studies, it can be stated that the content of Na in Pleurotus ostreatus samples in our study is higher.…”

The species Pleurotus ostreatus is a commercially, gastronomically, and biotechnologically important fungus. Its strain variability has been little researched. The study provides an evaluation of 59 oyster mushroom production strains in terms of the ability to accumulate selected metals in the cap and stipe. The fruiting bodies were grown under identical model conditions on straw substrate. Metal concentrations (ET-AAS) in dry fruiting bodies ranged in values 1.7–22.4 mg kg−1 for Al, 2.6–9.7 mg kg−1 Ba, 199–4560 mg kg−1 Ca, 1.7–12.0 mg kg−1 Cu, 12–120 mg kg−1 Fe, 16,000–49,500 mg kg−1 K, 876–2400 mg kg−1 Mg, 0.39–11.0 mg kg−1 Mn, 46–920 mg kg−1 Na and 11–920 mg kg−1 for Zn. More Cu, Fe, K, Mg, Mn, Zn accumulated in the cap, while in the stipe Ba was amassed. No significant difference was found between Al, Ca and Na between the accumulation in the cap and the stipe. Furthermore, the dependence of metal uptake from the substrate depending on the fortification of the substrate was confirmed. Statistically significant (p < 0.05) synergistic relationships were shown in pairs Al and Ba, Al and Fe, Ba and Na, Ba and Ca, Ca and Na, Cu and Fe, Fe and Mn, Fe and Zn, K and Mg, K and Mn, K and Zn, Mg and Mn, Mg and Na, Mg and Zn and Mn and Zn in the substrate without the addition of sodium selenate to the substrate. Altered relationships were observed after the application of sodium selenate to the substrate, synergism of Se and Ni, Se and Co and Se and Hg, Cu and Mn, Cu and Fe, Zn and Co, Zn and Ni, Zn and Hg, Mn and Fe, Mn and Cr, Co and Ni, Co and Hg, Ni and Hg, Pb and Cd. The findings of the study may help in the selection of production strains with hypercumulative properties for a particular metal and subsequent use in the addition of fortified fruiting bodies (e.g., with Zn). Based on the study the strains less sensitive to the accumulation of hazardous metals is possible to select for large-scale production, which is important from the perspective of food safety.
