THE BIOMINERAL CONCENTRATIONS AND ACCUMULATION IN SOME WILD GROWING EDIBLE SPECIES OF MUSHROOMS

Many mushrooms species are known to accumulate metals to a higher level than the plants and are considered as a source of proteins, vitamins – riboflavin, biotin and thiamine, fats, carbohydrates, amino acids and minerals. The trace metals concentrations were established by Inductively Coupled Plasma - Atomic Emission Spectrometry method. The aim of this paper is to determinate the minerals content of some wild growing mushrooms, which may be useful in the phytopharmaceutical biotechnologies in order to obtain important quantities of biominerals accessible for the human body. The results are varying with the analyzed species of mushrooms between 11869.85 and 32088.68 mg/kg for potassium, 240.81 to 716.98 mg/kg for calcium and between 0 to 5350 mg/kg for phosphorus. The highest concentration if potassium was founded in B. griseus species, 32088.68 mg/kg. Only two species, Hygrophorus virgineus and Marasmius oreades show a phosphorus concentration in the fruiting body higher than in soil, indicating the accumulation capacity.
