The antibacterial activity of the oil was evaluated via the disc diffusion bioassay against. The oil showed significant activity against Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli. However, it showed partial activity against Bacillus subtilis and it was inactive against the yeast Candida albicans.
