Antibacterial Effect of Turkish Black Cumin Seed Oil Against Pathogen Bacteria's

Abstract

Black cumin seeds are used for medicinal and aromatic purposes in Turkey. Black cumin seed oil (BSCO) was provided from a local producer. BCSO was extracted by cold-pressing method. Antibacterial effect of BCSO was investigated against B. cereus (ATCC 10876), L. monocytogenes (ATCC 19115), E. coli (ATCC 25922), Salmonella Thypimurium (ATCC 14028) and S. aureus (ATCC 25923) by minimum inhibitory concentration (MIC) method. MIC values were determined according to micro tube dilution method. BCSO had antibacterial effect against B. cereus and S. aureus and didn’t have antibacterial effect against other bacterias. B. cereus and S. aureus are Gram (+) and others are Gram (-). In various studies, it had been found that Gram (+) bacterias are less resistance to aromatic oils. Fatty acid composition of BCSO was investigated for additional information of material and major fatty acids of BCSO are linoleic acid, oleic acid and palmitic acid. As a results, study suggests that cold-pressed BCSO can be used for its functional property. Pract?cal Appl?cat?ons Black seed oil is widely used in ethnopharmacology. It is marketed as a treatment agent for many mild diseases in the shops called "Aktar" in Turkish culture and it finds a response by the public. However, its use in industry is limited due to its pungent odor and taste. In this study, the functional properties of black cumin oil were investigated.
