ABSTRACT
Model experiments have shown prolonged nature of impact of veterinary antibiotic tylosin (100-600 mg/kg) and its complex with fungicidal antibiotic nystatin at the same concentrations on microbiocenosis and enzymatic activity of ordinary chernozem. Full rehabilitation of chernozem biological properties does not take place even after 120 days. According to the degree of resistance to tylosin, the studied microorganisms formed the series (concentration of 600 mg/kg): micromycetes > Azotobacter genus bacteria > amylolytic bacteria > ammonifiers bacteria; ferments formed the following series: catalase > dehydrogenase > invertase > phosphatase.

Keywords: pollution, tylosin, microorganisms, enzymatic activity, chernozem.
