[Isolation and investigation of natural yeast strains resistant to heavy metal salts and radionuclides].
The collection of yeasts (more than 2000 strains) from extreme natural environment of Kamchatka peninsular and Kuril Islands was created. 448 strains were selected for their resistance to salts of such heavy metals as Cu, Cd, Co and to high temperature (37-52 degrees C). 72% of strains appeared to be resistant to one or more selective factors. We obtained several strains able to grow on medium with 0.1 M/L nonradioactive strontium and (or) cesium. Four of this strains accumulated radioactive isotope 90Sr with 45-80% efficiency. Thus, we demonstrated that yeast strains from nature could be used for bioremediation of industrial waste solutions, polluted by radionuclides and salts of heavy metals.
