Abstract


Currently, the antibacterial properties of honeydew honey are increasingly valued, being regarded as superior to blossom honeys. Over the years, the antibacterial activity of propolis has been highly appreciated, due to the flavonoids and phenolic acids present in its composition. Moreover, essential thyme oil and sea buckthorn oil have been recognized as valuable resources of natural antimicrobial compounds. The present research aimed to evaluate the antibacterial potential of two natural mixtures, consisting of honeydew honey and sea buckthorn oil and honeydew honey, propolis soft extract and essential thyme oil respectively. The tested bacterial strains were represented by Staphylococcus aureus ATCC 6538P, Bacillus cereus ATCC 11778, Escherichia coli ATCC 25922, Salmonella enteritidis ATCC 13076, Pseudomonas aeruginosa ATCC 27853 and Enterococcus faecalis ATCC 29212. Our results showed that the investigated products recorded good antibacterial activity and the Gram-positive bacterial strains were more sensitive than the Gram-negative ones.
