Antimicrobial activity of exocellular metabolites Acinetobacter calcoaceticus IMV V-7241, Rhodococcus erythropolis IMV Ac-5017, Nocardia vaccinii K-8 ON Phytopathogenic bacteria / К. А. Pokora, K. V. Chebotarova // Ukrainian food journal. – 2012. - № 2. – С. 35-38.https://dspace.nuft.edu.ua/handle/123456789/21504We investigated the effect of exocellular metabolites, including surface- active substances (surfactants) of Rhodococcus erythropolis IMV Ac-5017, Acinetobacter calcoaceticus IMVВ-7241 and Nocardia vaccinii K-8 on somephytopathogenic bacteria. It was shown that after 2 h treatment with surfactant preparations (0.15 - 0.4 mg/mL of strains IMV Ac-5017 and IMV В-7241 survival of genus pathogenic bacteria (105 - 107 in mL of Pseudomonas and Xanthomonas was 0 - 33%. In the presence of a surfactant preparations (0.085 - 0.85 mg/mL), and other exocellular metabolites of N. vaccinii K-8 number of cells of studied phytopathogenic bacteria reduced by 95 - 100 %. The results show the possibility of use microbial surfactants for the development of environmentally friendly products to control the number of pathogenic bacteria.phytopathogenic bacteriasurface-active substancesповерхнево-активні речовинифітопатогенні бактеріїкафедра біотехнології і мікробіологіїArticle
