The component and antibacterial effects of six essential oils )EOs(, including Cuminum cyminum (CCEO), Artemisia sieberi (ASEO), Laurus nobilis (LNEO), Ferula Gummosa essential (FGEO), Lippia citriodora (LCEO), Cymbopogon citratus (CIEO) were measured by GC-MS and 96-well micro-plates (IC50), against Staphylococcus aureus and Pseudomonas aeruginosa. Then, the antibacterial effects of FGEO, the most efficient EO, were examined on the trolley surface in hospital for 1, 3, 5 and 10 min intervals. While CCEO, ASEO, and FGEO have the highest effects on the growth of S. aureus, CIEO and LNEO showed the best outcomes on P. aeruginosa. In addition, our finding showed that FGEO relatively decreases the growth of S. aureus and P. aeruginosa on the trolley surface (P < 0.05). In addition, FGEO, one of the best disinfectant agents of the present study, showed relatively antibacterial effects on the surface of the trolley.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
