Table 2.
Verification of the consortium ability to inhibit activity of tested plant pathogenic bacteria. The table shows ability of the developed consortium (107 CFU mL⁻¹ ) to inhibit the growth of individual plant pathogenic bacterial strains and their mixture. Taxonomic identity of the pathogenic strains was confirmed as Pectobacterium carotovorum (Pc), Burkholderia cepacia (B3217), Enterobacter cloacae subsp. dissolvens (Edi), Kosakonia cowanii (CH51) (PZ315353, PZ315355, PZ315356, PZ315354)
