Antibacterial activity of six essential oil against some pathogenic bacteria

In the present study effort have been made to find the anti-bacteria effect of six medicinal plant essential oil namely, Ocimum bascilicum (Basil oil), mentha arvensis (Cormint oil),Zingiber officinale(ginger oil),citrus limon(lemon oil), thymus mastichina (Marjoram oil) and mentha spicata (Spearmint oil) were assessed for anti bacterial activity against therefore pathogenic bacteria such as B.cereus, E.aerogens, E.coli, K.oxytoca, K.pnemoniae, L.vulgaris, P.aeruginosa, P.mirabilis, S.paratyphi, S.facsalis, S.typhi, S.aureus and V.cholera. The activity was measured in terms of zone of growth inihibition in mm. These included animal and plant pathogens, food spoisoning and spoilage bacteria. The essential oils exhibited considerable inhibitory effects against all organism. The essential oil show the strong growth inhibiting activity was found in the lemon oil and moderate growth inhibition was found in the essential oil of Basil oil, ginger oil Marjoram oil, and spearmint oil. However, the lowest range of growth inhibition was found in the cormint oil. © 2010 IJRSR. All rights reserved.
