The majority concentrations of essential oil did not give any antimicrobial results. Turkish oil gave the inhibition against P. aeruginosa at the concentration 1, 0.5 and0.25 mg/ml with the range of 0e7 mm. However, P. vulgarisand S. aureus gave inhibition against Turkish oil only at the concentration 0.5 mg/ml with the diameter zone 5 and 6 mm. But E. coli did not show any activity at any concentration. However, Indian lemon oil gave the inhibition against the pathogenic bacteria such as E. coli, S. aureus and P. aeruginosaat the concentration of 2mg/ml with inhibition zone 6, 75 and 70 mm (Table 3). P. vulgaris did not give any activity at the concentration 2 mg/ml. But, the Indian essential oil at concentration 0.25 against P. vulgaris gave small activity. Whereas, Indian essential oil at concentration 0.25 against the S. aureus gave very strong activity (Table 3).
