Summary: | The number, diversity, and structure of the actinomycetal complexes in the soils of the industrial and residential zones of the city of Kirov are considered. The total content of mobile cadmium, zinc, lead, iron, and nickel in the soils of the industrial biotopes was 1.8 and 6.0 times higher than their concentration in the soils of the residential and background zones, respectively. In the heavy metal (HM)-polluted soils, the share of actinomycetes in the total number of prokaryotes and the relative abundance of the micromono-spores in the actinomycetal complex were much higher and the species diversity of the streptomycetes was lower than these characteristics in the soils of the residential zone. The differences in the composition of the mycelial prokaryote complexes appear to be related to the selective resistance of some of their representatives to heavy metals. The possibility to select the strains resistant to HMs and suitable for use in the bioremediation of polluted soils is considered. |
