The research presents the results of oyster mycelium growth on the liquid medium. The mycelim growth: Pleurotus citrinopileatus Singer, P. djamor (Rumph.: Fr.)Boedjin, P. erynii (DC.)Gillet and P. precoce (Fr). Quél. was tested. The quality and quantity of mycelium was assumed.
The substratum photomorphogenesis — the increase of dry weight in light as compared with darkness — takes place only on the nutrient solution with yeast extract. On a synthetic medium with the phosphate level varying from 2.87 to 22.96 mM, the dry weight of mycelia is the same in light and in darkness. In a similar way the phosphorus content in the mycelia and the amount of this element taken up are not related to light conditions. The organism utilizes about 66% of the phosphate present in the nutrient solution.
Translocation of selected heavy metals in a mycelium growing in an agar medium supplemented with heavy metals was studied. The study showed that zinc, cadmium and lead were higly accumulated in the mycelium structures and that mycelium actively inhibited metal ion translocation.
