The molecular genetic identification of bacterial strains of genus Pseudomonas isolated from soil and vegetative material of potato plants (Solanum tuberosum) was carried out. PCR analysis using the genus-specific OpriF / OpriR primer showed that 9 samples of a pure bacterial culture were characterized by the presence of one amplicon characteristic of Pseudomonades. Affiliation of selected bacteria to genus Pseudomonas was confirmed by a comparative analysis of the deciphered nucleotide sequence of the 16S rRNA gene with the reference nucleotide sequences of typical strains from the RDP database. A wide range of enzymatic activity and pronounced antagonistic properties in relation to phytopathogenic micromycetes of genera Alternaria and Fusarium were established in selected strains of bacteria.
