Ability of Pleurotus eryngii mycelium to absorb selenium depending on the selenium source and concentration in medium

Abstract

The aim of our research was to investigate the influence of three different inorganic Se sources, added to the synthetic medium, on the Pleurotus eryngii mycelium ability to absorb and retain this microelement. All investigated P. eryngii strains were good Se absorbers from the media enriched with all studied Se sources. Strain HAI 711, which was cultivated in the Na2SeO4-enriched medium at Se concentration of 1.0 and 1.3 mgl-1 respectively, showed extraordinarily high Se concentrations in the mycelium (725 μgg-1 of dry weight and 575 μgg-1 of dry weight, respectively).
