AbstractCinnamon essential oil (CEO) has antibacterial properties, but its ability to suppress the formation of multi-species oral biofilms has not been fully elucidated. This study evaluated the antibacterial and antibiofilm activities of cinnamon essential oil nanoemulsion (CEON) against oral biofilms formed using a microcosm biofilm model. The biofilms were formed on bovine enamel specimens over a 7-day period, during which all specimens were treated with one of three solutions: 5% CEON (n = 35), 0.5% cocamidopropyl betaine (n = 35), or 0.12% chlorhexidine gluconate (CHX; n = 35). Antibacterial and antibiofilm activities were determined by the red/green ratios (R/G values) of 7-day-old mature biofilms photographed with quantitative light-induced fluorescence-digital, the number of aciduric bacterial colony-forming units (CFUs) within each biofilm, and the absorbance of bacterial suspensions. One-way and repeated-measures analysis of variance were performed to compare differences among the three solutions. R/G values were lowest in the 0.12% CHX group, but not significantly differ from the 5% CEON group. The number of CFUs and absorbance were lowest in the 5% CEON group. This study showed that nanoemulsified CEO inhibited the maturation of multi-species oral biofilms and the growth of oral microorganisms in biofilms, including aciduric bacteria that cause dental caries.

<p>This experiment was performed to investigate the effects of some essential oils on chemical properties and aerobic stability of lucerne silage. Treatments included lucerne silage without additives (control), lucerne silage with 60 mg cinnamon essential oil/kg, lucerne silage with 60 mg flaxseed essential oil/kg, lucerne silage with 60 mg lemon seed essential oil/kg, lucerne silage with 180 mg blend of essential oils (60 mg cinnamon + 60 mg flaxseed + 60 mg lemon seed essential oils/kg).<strong> </strong>Adding essential oils to lucerne silage reduced silage pH (<em>p </em>&lt; 0.001) compared to control. The highest level of total volatile fatty acids (tVFA) was found when lemon seed essential oil and the lowest level when flaxseed essential oil was used. The lucerne silages treated with essential oils had the highest crude protein contents (<em>p </em>&lt; 0.01). Untreated lucerne silage had the highest level of gas production compared to lucerne silage treated with lemon seed and flaxseed essential oils (<em>p </em>&lt; 0.01). The essential oil additives increased the aerobic stability of the silage. It can be concluded that the use of essential oil additive in the preparation of high quality lucerne silage, can improves the quality and nutritive value of silages.</p>

The antimycobacterial activity of cinnamaldehyde has already been proven for laboratory strains and for clinical isolates. What is more, cinnamaldehyde was shown to threaten the mycobacterial plasma membrane integrity and to activate the stress response system. Following promising applications of metabolomics in drug discovery and development we aimed to explore the mycobacteria response to cinnamaldehyde within cinnamon essential oil treatment by untargeted liquid chromatography–mass spectrometry. The use of predictive metabolite pathway analysis and description of produced lipids enabled the evaluation of the stress symptoms shown by bacteria. This study suggests that bacteria exposed to cinnamaldehyde could reorganize their outer membrane as a physical barrier against stress factors. They probably lowered cell wall permeability and inner membrane fluidity, and possibly redirected carbon flow to store energy in triacylglycerols. Being a reactive compound, cinnamaldehyde may also contribute to disturbances in bacteria redox homeostasis and detoxification mechanisms.
