Antimicrobial activity of extracts of basil (Ocimun sanctum L.) | Actividad antimicrobiana de extractos de albahaca (Ocimun sanctum L.)

إنجليزي. The objective of this research was to investigate the antimicrobial activity of extracts of basil (Ocimum sanctum L.), on: Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Saccharomyces cerevisiae and Aspergillus oryzae. It was obtained that the inhibitory minimum concentration for E. coli was 1500 mg/kg; for St. aureus 750 mg/kg and S. cerevisiae 500 mg/kg. For B. subtilis, the extract caused bacteriostatic effect and on A. oryzae inhibition was not found at any of concentrations neither studied times. Keywords: antimicrobial activities, phenolic compound, basil.
