[Population dynamics study of Streptomyces olivocinereus in soil].

The dynamics of the population of the soil actinomycetes Streptomyces olivocinereus can be studied in its natural habitat using a conventional technique of inoculation at a level of the population density close to the natural one. The colonies are registered and counted in UV where they are clearly visible due to their bright orange luminescence. Techniques employed for obtaining information about the population structure (spores--mycellium) are described. The dynamics of the population has been studied within a year. The population introduced into soil is stabilized at a relatively high level.
