Zn(II) Induces Fibril Formation and Antifungal Activity in Shepherin I, An Antimicrobial Peptide from Capsella bursa-pastoris.

Researchers found that the peptide shepherin I from shepherd's purse has strong antifungal activity when it binds with Zn(II) ions, causing a structural change and the formation of fibrils. This suggests a link between metal binding, morphology, and biological activity.

Optimization of oil yield of Pelargonium graveolens L'Hér using Box-Behnken design in relation to its antimicrobial activity and in silico study.

The study optimized the extraction of oil from Pelargonium graveolens and found that autumn yielded the highest amount. The oil showed antimicrobial properties and was effective against Gram-negative bacteria and MRSA when combined with certain antibiotics. This has potential applications in the perfume, cosmetic, and medical industries.

Exploring the Antimicrobial Properties of 99 Natural Flavour and Fragrance Raw Materials against Pathogenic Bacteria: A Comparative Study with Antibiotics.

This study examines the antimicrobial properties of natural fragrance raw materials on multidrug-resistant microorganisms. The substances with the lowest MIC values were black seed oil, fir balsam absolute, and cubeb oil. The findings can help in developing treatments for infectious diseases and reducing microbiological contaminations in cosmetic products.
