Abstract

Tons of pharmacologically active substances are used by human annually in medicine, agriculture, and for farm-animal production. The influence of pharmaceutical antibiotics (benzylpenicillin, pharmazin, and nystatin) in different doses (100, 300, 450, and 600 mg/kg) on a number of microorganisms of the chernozem region has been studied. All tested doses of pharmaceutical antibiotics had a significant inhibitory effect on the abundance of soil microorganisms. Bactericidal drugs (benzylpenicillin) are most effective against ammonifiers and bacteriostatic drugs (pharmasin) are effective against amylolytic bacteria. In complexes of antibacterial antibiotics with fungicides, a less significant effect on ammonificators was established; this is not true for amylolytic bacteria. There is a linear dependence between the dose of antibiotics and a change in the abundance of soil microorganisms. The higher the concentration of the introduced antibiotic is, the stronger the inhibitory effect is. In terms of resistance to pharmaceutical antibiotics, the studied groups of soil microorganisms formed a series (high concentrations): bacteria of genus Azotobacter > amylolytic bacteria > ammonifiers >micromycetes.
