    Activity of streptomyces Spp. from agriculture soils against phytopathogens
    (CEP USM, 2024) Burțeva, Svetlana; Birsa, Maxim; Sasanelli, Nicola
    Antimicrobial activity of Moldovian selected strains of streptomycetes revealed that the growth of test cultures was actively delayed by 11 Streptomyces strains. Strain Streptomyces sp. 9 caused the formation of zones of lacking growth in 6 out of the 11 phytopathogens tested. Metabolites of the strains Streptomyces spp. 10 and 33 completely suppressed Alternaria alternata growth, while Streptomyces spp. 10 and 17 – Botrytis cinerea, strain Streptomyces sp. 10 – Fusarium graminearum. Growth of Clavibacter michiganensis was completely suppressed by the metabolites of the strain Streptomyces sp. 145. Results confirm the prospective to continue the research in bio-pesticide usage.
