Article Synopsis
- * The yeast strains demonstrated resilience, growing in high concentrations of sucrose, salt, and extreme temperatures, and showed significant inhibition of mycotoxigenic species that affect dates, with inhibition percentages between 43.6% and 70.3%.
- * The strains produced volatile compounds that effectively inhibited fungal growth and sporulation, indicating their potential as a safe and eco-friendly alternative to synthetic fungicides for protecting stored dates.
Article Synopsis
- The study evaluated how two strains of Saccharomyces cerevisiae, both alive and dead, could remove ochratoxin A (OTA) from grape juice contaminated with the toxin.
- One strain was a commercial yeast used in winemaking, while the other was isolated from table grapes.
- Results showed that both strains, especially in their dead form, significantly reduced OTA levels in both artificially and naturally contaminated grape juice after just one hour of contact.
Biological control of brown spot pathogen, by different essential oils.

August 2023
Article Synopsis
- The study investigated the antifungal effects of laurel, myrtle, and peppermint essential oils on the mycelial growth of Alternaria alternata and on Citrus leaf disease.
- Myrtle oil contained α-pinene and 1,8-cineole, while peppermint oil was rich in menthol and menthone, with laurel oil primarily composed of 1,8-cineole.
- The essential oils effectively inhibited fungal growth at a concentration of 3 mg/mL, with a notable synergistic effect observed when peppermint and laurel oils were combined, significantly reducing mycelial growth on infected leaves at concentrations above 1.5 mg/mL.
An increasing human population necessitates more food production, yet current techniques in agriculture, such as chemical pesticide use, have negative impacts on the ecosystems and strong public opposition. Alternatives to synthetic pesticides should be safe for humans, the environment, and be sustainable. Extremely diverse ecological niches and millions of years of competition have shaped the genomes of algae to produce a myriad of substances that may serve humans in various biotechnological areas.

Many of the currently used synthetic pesticides are not authorized for application in organic agriculture. In addition, the developed resistances of various pests against classical pesticides necessitate the urgent demand for efficient and safe products with novel modes of action.
