Description
  • Some plants contain various compounds, which can influence microbial growth, reproduction or basic cell functions. Phenols, polyphenols, micronutrients, essential oils and other compounds belong to them. These compounds are primarily present in various herbs. Extract s from these plants could be used as natural food preservatives, which could inhibit growth of undesirable microorganisms. In this work, antimicrobial activity of aqueous extracts of Thymus vulgaris, Lavandula angustifolia, Melissa officinalis, Ocimum basilicum , Allium schoenoprasum and Petroselinum crispum was tested on five gram negative bacteria -- Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae, Hafnia alvei and Raoultella terrigena, which were isolated from dairy products except Escherichia coli (CCM 7929). Antimicrobial activity was tested by disc diffusion method. It was found out the less effective extracts were from thyme and lavender. Basil, chive and parsley extracts showed higher potential to inhibit bacterial growth.
