“…In this way, several binary or ternary combinations have exhibited synergistic antimicrobial activities for different mixtures of components of essential oils [69,70]. This synergy could be a result of some components present in EOs attached to the surface of the cell, and thereafter some other could penetrate the phospholipid bilayer of the cell membrane [57]. The result is a disruption of the cell membrane by their accumulation, negatively affecting the cell metabolism and causing cell death [71,72].…”

“…The essential oil of Ruta graveolens was acquired from Krauters (Bogotá, Colombia), and its composition was determined by gas chromatography-mass spectrometry (GC-MS) according to the methodology reported by [57], using an AT 6890 Series plus gas chromatography spectrometer, with a mass selective detector (full scan). A DB-5MS fused silica capillary column was employed with a temperature ramp of 60 °C for 10 min, then 5 °C/min to 250 °C, and maintained for 10 min.…”

Guava is a fruit appreciated worldwide for its high content of bioactive compounds. However, it is considered a highly perishable fruit, generally attacked by pathogenic species such as the fungi Colletotrichum gloeosporioides, which causes anthracnosis. To diminish the losses caused by pathogenic fungi, coatings of chitosan (CS) with Ruta graveolens essential oil (RGEO) in different concentrations (0.5, 1.0, 1.5% v/v) were applied in situ and their effects on the physical properties and microbiological quality of the guavas were studied. The CS+RGEO coated fruits exhibited better physicochemical behavior and lower microbiological decay as compared to the uncoated guavas, demonstrating the effectiveness of the coatings, especially those with 1.5% of RGEO content. All the fruits coated had greater acceptance and quality than the controls, being more those with essential oil incorporation. In situ investigation of C. gloesporioides infection of guavas demonstrated that the CS+RGEO coated guavas showed a high percentage of inhibition in the development of anthracnose lesions. In the present investigation, an alternative method has been proposed to extend the stability of the guavas fruit up to 12 days with application in the food industry.

“…They recorded that, Penicillium nalgiovense and Aspergillus parasiticus were more resistant to the essential oil of Austroeupatorium inulifolium (Grande-Tovar et al, 2016) whilst both fungal isolates were tend to be more sensitive to the Juniper essential oil in current study.…”

“…Similar results were reported by Talepzadeh et al (2012) that, growth of Neocallimastix-like fungal isolate was totally inhibited when it was cultured in the medium containing essential oil of Zataria multiflora. Furthermore Grande-Tovar et al (2016) studied the possible effects of essential oil, extracted from Austroeupatorium inulifolium, on the survival of the aerobic fungal genera namely Aspergillus spp, Pencillium spp and Fusarium spp and they reported that fungal growth was inhibited up to 70% by this essential oil.…”

Due to the ban on antibiotics and ionophores, which were used as feed supplements, scientists have become more interested in evaluating other alternatives to control the rumen fermentation. Plant essential oils might be alternative to that kind of supplements for farm animals. However, our knowledge about the possible effects of plant essential oils on survival rate and enzyme activity of anaerobic fungi (besides other rumen microbes) is still limited. Current study, therefore, aimed to determine the effects of plant essential oils on this unique group of rumen microorganisms. Effects of various dosages of myrtle (Myrtus communis), juniper (Juniperus communis), melissa (Melissa officinalis) and thyme (Thymus vulgaris) plant essential oil, which have antimicrobial properties, were investigated on survival rate and enzyme activity of Neocallimastix sp. GMLF2 and Orpinomyces sp. GMLF18. Accordingly, plant essential oils were dissolved in ethyl alcohol and added into medium. Fungal growth (Neocallimastix sp. GMLF2 and Orpinomyces sp. GMLF18) was completely inhibited in the 1 mg/ml essential oil concentration of culture medium. Furthermore carboxymethylcellulase and xylanase activities were decreased remarkably when 0.5 mg/ml concentration of essential oil was added into culture media regardless of type of the oil.

“…After GC-MS and GC-FID analyses, 25 compounds were recognized in the essential oil (Table 1): 23 monoterpenes (99.7%), one sesquiterpene (0.2%) and one non-identified compound. Monoterpenes have been described to exert acaricidal (Sánchez-Ramos and Castañera 2000) and antimicrobial (Dorman and Deans 2000) effects, while sesquiterpenes might account for antimicrobial and antifungal properties (Grande-Tovar et al 2016).…”

Chitosan-based coatings and films have been widely studied, demonstrating to be an efficient and eco-friendly approach to extend the shelf life of food products. The effect of incorporating essential oil (TCEO) at different concentrations (0.5, 1.0, and 1.5% w/w) on physical, mechanical and antimicrobial properties of chitosan films was studied. The antimicrobial activity of the films was evaluated by agar diffusion method, against 23 spoiling microorganisms isolated from tuna and swordfish (ten , one, one , two, two , five spp., one and one) and ATCC 49138. The films exerted antimicrobial activity against all the tested strain, although not proportional to increasing TCEO concentration. In particular, was the most sensitive species and the inhibition was stable after 72 h. In general, TCEO incorporation in chitosan films, significantly ( < 0.05) decreased the water permeability (from 0.577 ± 0.060 gmm/kPahm at 61% R.U. for chitosan to 0.487 ± 0.037 gmm/kPahm for the film with 1.5% TCEO), the elongation at brake (from 27.322 ± 2.35% for chitosan to 14.695 ± 3.99% for the film with 1.5% TCEO) and increased the tensile strength (from 1.697 ± 0.16% for chitosan to 19.480 ± 2.86% for the film with 1.5% TCEO). Moisture content and water contact angle of the films also showed a similar trend with TCEO introduction, because of crosslinking reaction among the polymer chains and TCEO components. Scanning electron microscopy confirmed structure-properties relationships. These results suggest chitosan films incorporated with TCEO as an alternative treatment to inhibit the growth of degradative bacteria with potential application in the fish industry. The importance of testing more than one strain of the same bacteria species to evaluate the effectiveness of chitosan-essential oils coatings was also demonstrated.
