The hydrodistilled essential oils from the exudates of
Pistacia
vera
L.
stems have been tested against three bacteria,
Escherichia coli, Staphylococcus aureus and
Proteus using three methods: agar disc diffusion method,
determination of MIC (minimal inhibitory concentrations)
and in the liquid phase, by Maruzella method.
The results obtained showed that
E. coli
was the greatest inhibitor of all the strains tested, and
that
Gram
negative bacteria (E. coli and
Proteus spp.)
showed more inhibition than that observed on Gram positive
bacteria (S. aureus)
by the essential oil tested.
Key words:
Essential oils, oleoresin of
Pistacia vera
L., strains tested, antimicrobial activity determination.
