Abstract
Influence of different doses (100 mg/kg, 300 mg/kg, 450 mg/kg, 600 mg/kg) of pharmaceutical antibiotics (benzylpenicillin, pharmazin, nystatin) on the number of microorganisms of the chernozem was studied through model experiments. All studied doses of antibiotics have certain inhibitory effect on the number of soil microorganisms. Linear dependence between doses of antibiotics and changes in the number of soil microorganisms was established. As for resistance to pharmaceutical antibiotics the studied groups of soil microorganisms formed a row (high concentration): Azotobacter > amylolytic bacteria > ammonifying bacteria > micromycetes.
