This study evaluated the influence of the essential oil from Origanum vulgare L. on the enterotoxin production, membrane permeability and cell surface characteristics of Staphylococcus aureus. The suppression of enterotoxin production occurred totally in the broth added with the essential oil at subinhibitory concentrations (0.3 and 0.15 microL/mL). Loss of 260-nm-absorbing material and potassium ions occurred immediately after addition of the essential oil at 0.6 and 1.2 microL/mL and followed up to 120 min. Electron microscopy of essential oil-treated cells revealed the formation of roles in the cell surfaces and loss of cytoplasm material. According to these results, O. vulgare essential oil could be rationally applied in food products both to inhibit the growth of S. aureus and to suppress the synthesis of staphylococcal enterotoxins.

Lemongrass (Poaceae) is one of the aromatic plants with strong odors. Traditionally, lemon grass oil has been used for the treatment of many diseases such as gastrointestinal cramps, high blood pressure, high body temperatures, and fatigue, and is also considered an antibacterial and anti-diarrheal agent. Therefore, this study aims to investigate volatile active constituents and a few important biological activities of the volatile oil of lemongrass (Cymbopogon citratus) grown in Oman.

Accurately predicting the phase behavior and properties of reservoir fluid plays an essential role in the simulation of petroleum recovery processes. Similar to the inaccurate liquid-density prediction issue in the isobaric-isothermal (PT) phase equilibrium calculations, an inaccurate pressure prediction issue can also be observed in isothermal-isochoric (VT) phase equilibrium calculations which involves a liquid phase. In this work, a practical methodology is proposed to incorporate a volume-translated equation of state in VT phase equilibrium calculations for more accurate pressure predictions.

The misuse of tetracycline in livestock farming leads to environmental residues that promote the proliferation of antibiotic resistance genes (ARGs), particularly tetracycline resistance (tet) genes. Black soldier fly (BSF) larvae, used for organic waste bioconversion, may carry tetracycline residues in their guts, raising concerns about ARG spread. To address this issue, plant-derived additives such as lavender essential oil (LEO) have been explored as alternative antibiotics.

The urgent need to address the growing problem of antimicrobial resistance in multidrug-resistant bacteria requires the development of pioneering approaches to treatment. The present study aims to evaluate the antimicrobial potential of the essential oils (EOs) of Moringa oleifera (moringa), Cinnamomum verum (cinnamon), and Nigella sativa (black seed) and the synergistic effect of the mixture of these oils against Staphylococcus aureus MCC 1351. Statistical modeling revealed cinnamon oil had the highest individual antimicrobial potency, followed by black seed oil.
