This study evaluated the in vitro antibacterial activity of essential oils from Lippia graveolens (Mexican oregano), Origanum vulgaris (oregano), Thymus vulgaris (thyme), Rosmarinus officinalis (rosemary), Cymbopogon nardus (citronella), Cymbopogon citratus (lemongrass), and Eucalyptus citriodora (eucalyptus) against Escherichia coli (n = 22) strains isolated from Alouatta spp. feces. Minimum i...

An improved method of sample preparation was used in a microplate assay to evaluate the bactericidal activity levels of 96 essential oils and 23 oil compounds against Campylobacter jejuni, Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica obtained from food and clinical sources. Bactericidal activity (BA50) was defined as the percentage of the sample in the assay mixture...

An active packaging system has been designed for the shelf life extension of ready to eat meat products. The package included an inner surface coated with a chitosan film with thyme essential oil (0%, 0.5%, 1%, and 2%) not in direct contact with the meat. Our aim was to reduce the impact of thyme essential oil (EO) on meat sensory properties by using a chemotype with low odor intensity. The pH,...

The antifungal, antibacterial, and antioxidant activity of four commercial essential oils (EOs) (thyme, clove, rosemary, and tea tree) from Romanian production were studied in order to assess them as bioactive compounds for active food packaging applications. The chemical composition of the oils was determined with the Folin-Ciocâlteu method and gas chromatography coupled with mass spectrometry...

BACKGROUND Thymol (2-isopropyl-5-methylphenol) is the main monoterpene phenol found in thyme essential oil. This compound has revealed several biological properties, including antibacterial, anti-inflammatory and antioxidant activities. In this work, a comparison was made between the performance of different green solvents (ethanol, limonene and ethyl lactate), by pressurized liquid extraction ...

AIM/BACKGROUND The emergence of drug-resistant pathogens has drawn attention on medicinal plants for potential antimicrobial properties. The objective of the present study was the investigation of the antimicrobial activity of five plant essential oils on multidrug resistant Gram-negative bacteria. MATERIALS AND METHODS Basil, chamomile blue, origanum, thyme, and tea tree oil were tested agai...

in this study, rainbow trout (oncorhynchus mykiss) eggs were treated with effective doses of  daenensis thyme, thymus daenensis (20, 10 and 5 mgl-1) and mentha, mentha longifolia (10, 5 and 2.5 mgl-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. the mortality level in normal control (without any treatment) was sign...

In this study, it was aimed to evaluate the effectiveness of different levels thyme leaf and oil as feed additives in white shrimp (Litopenaeus vannamei) culture. experiment, five groups were formed 1% 2% leaves (ThyL1% ThyL2%), 0.5% (ThyO0.5% ThyO1%), control group. Shrimps (6.67±1.52 g) stocked at a stocking rate 15 shrimp/250 L (100% water change day-1) three-replications. At end trial, high...

a comparative study was made between the acaricidal activities of some essential oils: rosemary (rosmarinus officinalis l.), lavandula (lavandula angustifolia mill.), thyme (thymus vulgaris l.) and ziziphora (ziziphora clinopodioides lam.) on the important mite pest, tetranychus cinnabarinus boisduval, the carmine spider mite, oncut roses during 2010-2012. the sublethal concentrations of ziziph...

Four essential oils in two concentrations (50 and 100%) of thyme, Thymus vulgaris; Cinnamon, Cinnamomum zeylanicum; Lemon grass, Cymbopagon flexuosus; Anise, Pimpinella anisum and formic acid (65%) were used against varroa mite, Varroa destructor infesting honey bee colonies. Results show that, formic acid and the highest concentration (100%) of tested essential oils caused effective control of...
