ABSTRACT
Experiments with macromycetes Pleurotus ostreatus, Neonothopanus nambi, and Agaricus bisporus demonstrated for the first time that live mycelium of mushrooms, cultivated on a liquid culture medium, can efficiently take up dissolved Am in its biomass. Biochemical fractionation of the mycelium biomass demonstrated for the first time that the major fraction (up to 90%) of Am accumulated in the mycelium is bonded to structural polysaccharides of the cell walls. The sorption capacity of cell wall polysaccharides for Am is 2.7-3.6 times higher than that of the initial mycelium biomass, and the activity concentration of Am in the polysaccharides reached 950 Bq g dry weight.
