Prevalence of the actinomycetes of the Actinomadura genus in the virgin and cultivated light chestnut soils of the Volgograd Region was studied. It was shown that Actinomadura were one of the constituents of the actinomycetous flora of these soils. No significant changes in the number of the Actinomadura and the total number of the actinomycetes were observed in the cultivated and virgin soils. The cultures of Actinomadura isolated from the virgin and cultivated soils belonged to 17 and 18 known species, respectively. Some ecological indices were determined for estimation of the similarities and differences in the species structure of Actinomadura in the virgin and cultivated soils. It was shown that cultivation of the soils increased the species variety, equalization and general variety of Actinomadura. In the process of the species identification of Actinomadura the chemical nature of the pigments of the substrate mycelium of the same group of the isolates and the type culture of A. salmonea ATCC 33580 was studied. The pigment responsible for the colour of the substrate mycelium of A. salmonea belonged to the maduromycin group. The antagonistic properties of the Actinomadura isolated from the soils were studied. The isolates had a moderate antagonistic activity mainly against grampositive organisms.
对伏尔加格勒地区原生和耕种的淡栗钙土中马杜拉放线菌属放线菌的患病率进行了研究。结果表明，马杜拉放线菌是这些土壤中放线菌区系的组成部分之一。在耕种土壤和原生土壤中，未观察到马杜拉放线菌数量和放线菌总数有显著变化。从原生土壤和耕种土壤中分离出的马杜拉放线菌培养物分别属于17种和18种已知物种。确定了一些生态指标，以评估原生土壤和耕种土壤中马杜拉放线菌物种结构的异同。结果表明，土壤耕种增加了马杜拉放线菌的物种多样性、均匀度和总体多样性。在马杜拉放线菌的物种鉴定过程中，研究了同一组分离物的基质菌丝体色素以及鲑色马杜拉放线菌ATCC 33580模式菌株色素的化学性质。负责鲑色马杜拉放线菌基质菌丝体颜色的色素属于马杜拉霉素类。研究了从土壤中分离出的马杜拉放线菌的拮抗特性。这些分离物主要对革兰氏阳性菌具有中等拮抗活性。
