Abstract

Differences in the functional structure of streptomycete complexes isolated from ecotopes with varying degrees of contamination by heavy metals (HMs) have been revealed using data on the growth kinetics of representatives of the genus Streptomyces in the presence of lead, zinc, and copper ions. Streptomycete complexes isolated from moderately polluted soils (residential areas and garden plots in the city) and highly polluted soils (transport and industrial areas) are enriched in representatives reacting to metal ions (3 mg/L) by an increase in radial growth relative to the complex isolated from the soil of the control site, while the accumulation of biomass in a liquid medium containing 10 mg/L Pb2+ is less intensive in the former complexes than in the latter.
