Abstract

The aim of the research was to study the features of the influence of various concentrations of oil on the dynamics of the activity of the microflora of sod-podzolic soil and the residual amount of oil products when using biological products based on oil-oxidizing microorganisms. The article examines the dynamics of the number and composition of such physiological groups of microorganisms as heterotrophs, micromycetes, actinomycetes, cellulolytic. As a result of the studies, the following features were revealed: 1. low oil concentrations stimulate the number of all studied microorganisms; 2. micromycetes are the most resistant to oil pollution; 3. the most sensitive to the pollutant are actinomycetes and cellulite microorganisms. It was found that the biological activity of oil-contaminated soil correlated with the residual amount of oil products. The destruction of oil products is more intensive in the rhizosphere of wheat.
