Abstract

The mineral elements of Agaricus bisporus and Pleurotus ostreatus (separately in the caps and stipes of the fruit body) were analysed. The main conclusions are: 1. 1. The classical (conventional) and the new cultivation methods produce different mineral compositions in champignon. The new method (on pure wheat straw) produced lower B, Ca, Cu, Na, Zn and higher K, Fe, Mg, Ni, P and Ti concentrations. 2. 2. The caps of fruit bodies have, in general, greater concentrations of mineral elements than the stipes in both A. bisporus and P. ostreatus. The exceptions are Ba, Cd, Cr, Li and Sr, whose concentrations are approximately identical in caps and stipes). 3. 3. A. bisporus has higher P, K, Ca but lower trace element concentrations than P. ostreatus, which has higher Mg, B, Cd, Fe and Mn concentrations. 4. 4. Accumulation of heavy metals was not found in the samples examined.
