Mycelial growth of edible and medicinal oyster mushroom Pleurotus ostreatus (Jacq.:Fr.) Kumm. on selenium-enriched media

Abstract

The edible and medicinal oyster mushroom Pleurotus ostreatus (Jacq.: Fr.) Kumm. is economically highly praised for its nutritional and pharmacological value. One of selenium's roles is as an antioxidant when it acts as a cellular protector against free-radical oxidative damage. The aim of our research was to investigate the influence of selenium added to media on the growth rate ofmycelia, and the ability ofmycelia to accumulate this microelement. Analyzed concentrations of selenium did not show a significant influence on the mycelial growth in comparison to the control. The results of selenium accumulation in mycelia have shown higher concentration in hyphae grown on enriched media.
