[New species, Actinomadura fulvescens sp. nov. and Actinomadura turkmeniaca sp. nov. and their antagonistic properties].
Two new species of Actinomadura isolated from soil samples of the Turkmen SSR, i.e. Actinomadura fulvescens sp. nov. and Actinomadura turkmeniaca sp. nov. are described. The first species is characterized by formation of short (1-2 turns) spiral spore chains, smooth spores, scanty white aerial mycelium, colourless or yellowish substrate mycelium on synthetic media and brownish-yellow substrate mycelium and soluble pigment of the same colour on organic media. No melanoid pigment is secreted. The type culture is designated as INA 3321. The cultures of A. fulvescens show antibiotic activity. A. turkmeniaca is characterized by formation of short straight or spiral spore chains, smooth spores, scanty white aerial mycelium, substrate mycelium and soluble pigment of pinkish-violet colour, absence of melanoid pigment. The type culture is designated as INA 3344. The strains of this species have low antibiotic activity. The study on the use of carbon sources by the representatives of 7 species (9 strains) of Actinomadura showed that the majority of the cultures (5 species, 7 strains) produced no growth on the Pridham and Gottlieb medium (ISP-9) with various carbon sources, including glucose. Possibly this medium cannot be used as the main medium for investigation of the spectrum of carbohydrate consumption in Actinomadura.
