  • Title: [Population dynamics and structures of Streptomyces lanatus in 2 soil types].
    Author: Mikhaĭlov VV, Zenova GM.
    Journal: Mikrobiologiia; 1980; 49(6):1011-13. PubMed ID: 7207256.
    Abstract:
    The dynamics and structure(mycelium--spores) of a population of the soil actinomycete Streptomyces lanatus 21-5 were studied in two types of nonsterile soil using the technique of inoculation on solid growth media in combination with autofluorescence, heat treatment of the culture, and addition of antibiotics, when the population was introduced into soil at a level of density close to the natural one. The dynamics of the population was found to depend on the form (spores or mycelium) in which it was introduced into soil. The population was shown to be stabilized at different levels of density in various types of soil at an identical level of inoculation. The population was found to behave differently in various types of soil. The population was represented in soils preferentially by spores. The structural coefficient K changing from 0 (only mycelium) to 1 (only spores) was proposed in order to estimate quantitatively the structure of the population.
