Bioactivity of oregano (Origanum vulgare) essential oil against Alicyclobacillus spp.

Atividade antimicrobiana de kefir fermentado com subproduto de uva contra Alicyclobacillus acidoterrestris

“…In comparison to other natural compounds, the kefir extracts analyzed in this study obtained values of minimum inhibitory concentrations against A. acidoterrestris higher than the essential oil of oregano (Dutra et al, 2019) and bromelain (Anjos et al, 2016). Although the values of the bactericidal concentrations did not show the same result, the kefir extracts showed effective antimicrobial activity against the deteriorating microorganism.…”

“…Food safety is a global and important factor for the food industry and public health, so the concern with the use of synthetic preservatives, the discovery of microorganisms resistant to antimicrobial agents and the increase in consumption for natural foods are challenges for the industry of food (Miao et al, 2016). In this sense, natural antibacterial products have been studied to control the spoilage caused by the A. acidoterrestris, such essential oil of oregano, Piperaceae extracts, citral essential oils, rosemary extracts, grape seed extract (Dutra et al, 2019;Pascoli et al, 2018;Huertas et al, 2014;Piskernik et al, 2016;Molva & Baysal, 2015).…”

Electrospun Active Biopapers of Food Waste Derived Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) with Short-Term and Long-Term Antimicrobial Performance

“…In addition, they are classified as Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration (FDA) [11]. Among them, oregano essential oil (OEO) is one of the most important and it is widely used in the pharmaceutical, food, and cosmetics industries [12]. It comes from the genus Origanum that belongs to the Lamiaceae family [13], which is constituted by more than 38 monoterpenoids [14].…”

“…Their main active compounds are carvacrol, thymol, p-cymene, and γ-terpinene, which are responsible for its high antimicrobial and antioxidant activities [15,16]. These active compounds have been particularly related to the inhibition of G− bacteria such as Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), and Salmonella typhimurium (S. typhimurium) and G+ bacteria including Staphylococcus aureus (S. aureus), Listeria monocytogenes (L. monocytogenes), Bacillus subtilis (B. subtilis), Streptococcus pyogenes (S. pyogenes), and Alicyclobacillus acidoterrestris (A. acidoterrestris) [12,15,[17][18][19]. Some other studies have also demonstrated the high antioxidant activity of OEO, which ranges from 80% to 90% inhibition of free radicals of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2 -azino-bis-(-3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) [12,20,21] due to the presence of hydroxyl groups (-OH) in its chemical structure [22].Zinc oxide (ZnO) is an inorganic material, which can have up to three crystal structures including hexagonal wurtzite, cubic zinc-blende structure, and a rarely-observed cubic rock-salt (NaCl-type) [23].…”

Determination of the phytochemical profile, in vitro the antioxidant and antimicrobial activities of essential oil from Arbutus andrachne L. wood growing in Turkey

“…It is prominent to point out that the antioxidant activity of the essential oils depends on the species, harvest time and geographical attitude (Mechergui et al, 2016) which can be explained by fact that the oils chemical composition varies because of extrinsic and intrinsic factors (Dutra et al, 2019). The determined antioxidant activities were related to compounds, such as cinnamyl alcohol, isobornyl acetate and 4-tert-butylcyclohexyl acetate which are commonly presented in the essential oils.…”
