[Leaching of calcium, silicon, aluminum and iron from micromycetes grown in submerged culture in the presence of ground concrete].

The leaching of chemical elements from concrete by microfungi of genera Aspergillus and Cladosporium during fungal growth on the medium containing ground barrier concrete under submerged conditions has been studied. It was shown that the leaching of chemical elements depended on the process of growth and metabolites excretion, on fungi species and on concrete concentration on the medium. Specificity of metals mobilization by different fungi was found.
