Chernobyl effect : growth characteristics of soil fungi Cladosporium cladosporioides (Fresen) De Vries with and without positive radiotropism

Vol. 49, nr 4

309-318

Positive radiotropism is common in fungi isolated from the area of the Chernobyl power plant. The aim was to study the submerged growth of one of these fungi, strains of Cladosporium cladosporioides, to search for correlations between positive radiotropic reaction and melanin synthesis with growth responses under low-level gamma-irradiation. In contrast to control strains the conidial germination of Chernobyl strains was not affected by the radiation treatment. The highest level of biomass melanin and of inhibitory constant was found for one of the Chernobyl strains. The characteristics of the Chernobyl strains indicated an adaptation to an environment with ionizing radiation.
