Antimicrobial activities of selected essential oils against Fusarium oxysporum isolates and their biofilms

M.C. Manganyi, T. Regnier, E.I. Olivier, M.C. Manganyi, more

South African Journal of Botany > 2015 > 99 > Complete > 115-121

Fusarium infections, such as keratitis, are becoming increasingly difficult to control due to the build-up of resistance of fungi towards conventional antibiotics. Resistance is further enhanced by their ability to form fungal biofilms. Poor storage conditions and inadequate cleaning of contact lenses often lead to corneal infections. The solution to problems associated with contamination and resistance...

Improvement in quality and storage ability of rabbit semen by using black or thyme seed as dietary supplementation

Yassmine Moemen El‐Gindy

Journal of Animal Physiology and Animal Nutrition > 106 > 3 > 642 - 654

The quality of incubated or chilled rabbit semen is quickly lowered with time due to high‐rate production of reactive oxygen species (ROS). Black seed (BS) and thyme (THY) are rich sources of natural antioxidants, which may be able to control ROS production and improve semen quality for use in artificial insemination. In this study, V‐line rabbit bucks, seven months old, were fed diets supplemented...

Plant Biology > 22 > 1 > 81 - 89

Potato common scab is a worldwide disease mainly caused by Streptomyces scabiei. It seriously affects potato crops by decreasing tuber quality. Essential oils (EO) are natural products with recognised antimicrobial properties. In this research, the antibacterial activities of thyme, oregano, suico and mint EO against S. scabiei were analysed. Infected tubers and soil samples were used for bacterial...

Natalia Verónica Tonello, Fabiana D’Eramo, Juan Miguel Marioli, Agustín G. Crevillen, more

Microchimica Acta > 2018 > 185 > 7 > 1-8

An extraction-free method is described for the colorimetric determination of thymol (TY) and carvacrol (CA) isomers in essential oils by making use of the pH-dependent formation of gold nanoparticles (AuNPs). In solutions of pH 12, TY and CA form gold nanoparticles, while at pH ≤ 11 only CA does so. By taking advantage of this finding, two different approaches based on colorimetric assay (absorption...
