The Antifungal Activities of Syzygium aromaticum and Alpinia purpurata Extracts Against Candida krusei: Bioactivity Tests, Molecular Modeling, and Toxicity Tests.

Researchers found that extracts from Syzygium aromaticum and Alpinia purpurata can be used as alternative drugs to treat Candida krusei infections, which are highly lethal and resistant to fluconazole treatment. This offers potential new treatment options for combating this deadly fungal infection.

Albocycline Is the Main Bioactive Antifungal Compound Produced by Streptomyces sp. OR6 against Verticillium dahliae.

Actinobacteria from olive tree soil can potentially control Verticillium wilt. One strain, sp. OR6, produced albocycline which effectively inhibited the pathogen's growth. This marks the first evidence of albocycline's efficacy against Verticillium wilt, highlighting its potential as a biocontrol agent.

In Vitro Antioxidant and Antifungal Activities of Four Essential Oils and Their Major Compounds against Post-Harvest Fungi Associated with Chickpea in Storage.

This study evaluated the antifungal and antioxidant properties of essential oils derived from four plants. The EO with the highest antioxidant and antifungal activity was found to contain a high concentration of eugenol. Combining eugenol and carvacrol in a 1:3 ratio showed promising potential for grain protection during storage.
