The use of essential oils in foods has attracted great interest, due to their antagonistic action against pathogenic microorganisms. However, this action is undesirable for probiotic foods, as products containing Lactobacillus rhamnosus. The aim of the present study was to measure the sensitivity profile of L. rhamnosus and a yogurt starter culture in fermented milk, upon addition of increasing...

Antialgal activity of Zataria multiflora, Satureja khuzistanica and S. rechingeri were evaluated. These plant species are easily cultivable and their algicidal activity make them suitable candidate as biocontrol. This study aimed to identify effective algicidal compounds, practically new algicidal agents from essential oils of plants that could inhibit the growth of red tide microalgae. Prepare...

background: the rice weevil, sitophilus oryzae and rice moth, corcyra cephalonica are major and cosmopolitan insect. adults of s. oryzae (male and female) and both larvae are insatiable feeders on a great variety of grains. objective: this study was conducted to estimate the insecticidal effect of essential oils from peppermint, mentha piperita l. and black pepper, piper nigrum l. against two m...

PURPOSE The aim of this work was to identify the chemical composition of the essential oils obtained from the flowers and leaves of Elaeagnus angostifolia (Elaeagnaceae) along with evaluate the radical scavenging and general toxicity activities. METHODS A combination of GC-MS and GC-FID were utilized for analyzing the chemical profile of the essential oils extracted by hydro-distillation from...

The present study was conducted to characterize the in vitro antimicrobial activities of 3 essential oils [oregano, rosemary, and a commercial blend of essential oils (BEO)] against pathogenic and nonpathogenic bacteria and to evaluate their effects on broiler chicken performances. The chemical composition of the essential oils was determined using the gas chromatography interfaced with a mass ...

The antimicrobial activity of Lavandula angustifolia essential oil was assessed in combination with 45 other oils to establish possible interactive properties. The composition of the selected essential oils was confirmed using GC-MS with a flame ionization detector. The microdilution minimum inhibitory concentration (MIC) assay was undertaken, whereby the fractional inhibitory concentration (ΣF...

Background: Essential oils are very complex mixtures of compounds with variety of biological properties Objective: In the present study, the effect of Cumin (Cuminum cyminum), Sage (Salvia officinalis), Basil (Ocimum basilicum) essential oil at 250, 500, 750 and 1000 µL.L-1 and Thyme essential oil at 30, 60, 120, 250µL.L-1 on growth of Botrytis cinerea was investigated in in vitro condition. ...

Essential oils extracted from flower petals of palmarosa (Cymbopogon martini), evening primrose (Primula rosea), lavender (Lavandula angustifolia) and tuberose (Polianthus tuberosa) were tested for their antibacterial activities against gram-positive and gram-negative bacteria. Different concentrations of each essential oil ranging from 10-100% were tested. Both gram-positive and gram-negative ...

The antibacterial activity of essential oils hydrodistilled from local anise, coriander, cumin, marjoram, rosemary and thyme were screened against a group of food-borne pathogens comprising Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Escherichia coli O157:H7, Salmonella Typhimurium and Bacillus cereus. All the tested bacterial strains displayed varying degrees of susceptibi...

OBJECTIVE The purpose of this study was to assay the antifungal activity of selected essential oils obtained from plants against both fluconazole (FLU)-resistant and FLU-susceptible C. albicans strains isolated from HIV positive patients with oropharyngeal candidiasis (OPC). MATERIALS AND METHODS The essential oils were obtained by hydrodistillation method from Myrtus communis (My. communis),...
