[Directed isolation of Micromonospora generic cultures on a selective medium with gentamycin].

The results of using selective media with gentamicin for directed isolation of Micromonospora are presented. It was shown that the use of the selective media with gentamicin for isolation of actinomycetes from soils of usual humidity levels markedly increased the frequency of Micronomonospora detection. The use of the selective media with gentamicin for plating out silt substrates containing mainly Micromonospora had practically no effect on the increase in the number of the Micromonospora cultures grown. The number of antibiotic-producing Micromonospora isolated on the media with gentamicin was 3 times higher than that on the control media. The use of the selective media with gentamicin provided directed isolation of Micromonospora.
