Toplam 129 atıf DOI
The antimicrobial activities of the extracts of seven spices (cumin, Helichrysum compactum Boiss (HC), laurel, myrtle, oregano, sage and thyme) were examined in their capacity to inhibit the growth of Escherichia coli O157:H7. Spices were fractionated by the extraction method to obtain a methanolic fraction. Of the spices tested, thyme showed promising results by inhibiting growth both in paper disc assay and agitated liquid culture assay. Antibacterial effects of tested spices extracts vary related to concentrations. Thyme and oregano showed higher activity than the others. It was also found that laurel and HC markedly stimulated the growth of E. coli O157:H7. Statistically, important variations were found among the inhibitory effects of spice extracts. This study has shown that E. coli O157:H7 inhibition by spice extracts may be of use in the field of food preservation. © 2002 Elsevier Science Ltd. All rights reserved.

The antimicrobial effect of 11 selected Turkish spice essential oils was investigated against seventeen pathogenic bacteria. The antimicrobial activity of the essential oils of six spices (cumin, fennel, laurel, mint, marjoram, oregano, pickling herb, sage, savory, thyme (black) and thyme) was tested at four concentrations (0.2, 0.4, 1 and 2%) on various microorganisms (E. aerogenes, E. coli, E. coli O157:H7, K. pneumoniae, P. vulgaris, S. enteritidis, S. gallinarum, S. typhimurium, S. aureus, Y. enterocolitica, A. hydrophila, C. xerosis, M. luteus, M. smegmatis, E. feacalis, P. aeruginosa and P. fluorescens). All preparations showed antibacterial activity against at least one or more bacteria. The inhibitory effect of the essential oils was evaluated through paper disc diffusion method. In general, the essential oils at 1 and 2% levels were effective. The most active essential oils were marjoram, thyme and oregano. According to the results, the studied essential oils potentially might be used as antibacterial agents to prevent the spoilage of food products, although further research is needed.
