title: [Number, species composition and antagonistic properties of Actinomadura from soddy-podzolic soils and from soils in the tundra zone].
abstract: Occurrence of Actinomadura in the turf-podzol soils of the Moscow region and in the tundra soils of Taimir was studied. It was found that there were practically no Actinomadura in the tundra soils, while their occurrence in the turf-podzol soils was rather high and amounted to 5 per cent of the actinomycetous flora. The occurrence of Actinomadura in cultured soils was higher and their species composition was more diverse as compared to those in virgin lands. The isolates represented 10 species and only 6 of them were detected in the virgin lands. The Actinomadura cultures showed moderately antagonistic properties when tested with the streak plate method. The majority of the Actinomadura cultures were active only against grampositive organisms.
