Abstract: The ability of bioenrichment action of Iron. Zcinc and Selenium irons of Lentinus edodes. Agrocybe chuxingu and Flammulina velutipes cultured in the same and different media were compared.The results showed that medium composition, trace element concentrations and fungi strains can atytct the bioenrichment action of edible fungi.The high quantify of protein. fat and the concentration of iron Zinc and Selenium ions in the medium is more advantageous to bioenrichment of edible 1’ungi.The best ability of’ bioenrichment action of iron and Zinc ions is Lentinus edodes and the bioenrichment action of Selenium ion of Flammulina velutipes is very strong.The high concentration of iron Zinc and Selenium can promote mycelium growth of Lentinus edodes.
