Kumm., Pleurotus sajor-caju (Fr.) Singer, and Agaricus bisporus (Large) Sign. was determined. Dry matter, moisture, crude ash, protein, fat, cellulose, organic matter, and nitrogen-free extract were , , , , , , , and of dry weight, respectively. Mineral element contents were g K kg−1, g Ca kg−1 , g Mg kg−1, and g Na kg−1 as macronutrients, and mg Fe kg−1, mg Zn kg−1 , mg −1 −1 −1 −1 Mn kg , mg Cu kg , mg Cr kg , and mg Cd kg as micronutrients (dry wt). Furthermore, toxic elements, such as Pb, Ni, and Co, were not detected in any of the 3 species of mushroom.

Kumm., Pleurotus sajor-caju (Fr.) Singer ve Agaricus bisporus (Large) Sign.’in besin değerleri saptandı. Kuru madde, nem, ham kül, protein, yağ, selüloz, organik madde ve azotsuz öz madde miktarı sırasıyla; % 89,7-90,3, % 9,7-10,0, % 6,0-13,7, % 27,8-41,6, % 0,5-1,3, % 10,0-16,2, % 76,0-84,0 ve % 26,7-36,8 olarak gösterildi. Mineral element içerikleri; 14,1-45,6 K, 0,2-1,2 Ca, 0,4-1,9 Mg, 0,2-0,9 Na gibi makro elementler (g −1 −1 kg ); 176,5-838,0 Fe, 35,0-46,0 Zn, 4,8-65,4 Mn, 6,5-21,5 Cu, 0,0-11,5 Cr ve 0,0-1,65 Cd gibi mikro elementler (mg kg ) olarak belirlendi. Ayrıca, tüm mantar türlerinde Pb, Ni ve Co gibi toksik elementler ise .
