Resumen:
Pseudomonas syringae is one of the main causal agent of plant bacterial iseases. The objective was to evaluate the antibacterial activity of natural phenolic compounds against Pseudomonas syringae strains isolated foom soybean. Four phytopathogenic strains (Q, LS3, EM1 and LSC13) isolated from soybean plants of Córdoba province and provided by the Department of Microbiología e Inmunología of the Facultad de Ciencias Exactas, Físico-Químicas y Naturales (UNRC)were used. The minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of 11 phenolic compounds (carvacrol, thymol, isoeugenol, eugenol, vanillin, o-cresol, p-cresol, m-cresol, estragole, guaiacol and phenol) were evaluated. Carvacrol and thymol showed the highest bioactivity against the 4 strains evaluated. The thymol and carvacrol MICs were 0.23 mM and 0.13 mM, respectively, while the MBC value for thymol was 0.27mM and for carvacrol, 0.22mM. The compounds with the lowest antibacterial activity were phenol, guaiacol, and vanillin. All strains presented similar sensitivity to the evaluated compounds, which indicate their potential use as alternative to protect crops from bacterial infections.
