Treść
Agaricus bisporus species (J.E. Lange) Imbach one of the most popular Basidiomycota species was chosen for the research because of its dietary and medicinal value. The presented herein studies included determination of essential mineral accumulation level in the mycelium of A. bisporus, cultivated on liquid cultures in the medium supplemented with addition of the chosen metals’ salts. Quantitative analyses of Zn, Cu, Mg, and Fe in liquid cultures made it possible to determine the relationship between accumulation of the selected mineral in A. bisporus mycelium and the culture conditions. Monitoring of the liquid cultures and determination of the elements’ concentrations in mycelium of A. bisporus were performed using the flame technique of AAS method. Concentration of Zn in the mycelium, maintained in the medium with the addition of its salt, was in a very wide range from 95.9 to 4462.0 mg/g DW. In the analyzed A. bisporus mycelium, cultured in the medium enriched with copper salt, this metal concentration changed from 89.79 to 7491.50 mg/g DW; considering Mg in liquid cultured mycelium (medium with Mg addition), its concentration has changed from 0.32 to 10.55 mg/g DW. The medium enriched with iron salts has led to bioaccumulation of Fe in mycelia of A. bisporus. Determined Fe concentration was in the range from 0.62 to 161.28 mg/g DW. The proposed method of liquid A. bisporus culturing on medium enriched with the selected macro- and microelements in proper concentrations ratio have led to obtaining maximal growth of biomass, characterized by high efficiency of the mineral accumulation. As a result, a dietary component of increased nutritive value was obtained.
