Antifungal properties of oregano and clove volatile essential oils tested on biodeteriorated archaeological mummified skin

The study of the potential use essential oils in field Cultural Heritage has increased last decade due to their demonstrated antimicrobial and absence toxicity. This work aimed at assessing, for first time, volatile antifungal activity two (EOs) (Origanum vulgare Syzygium aromaticum) against fungi isolated from biodeteriorated archaeological mummified skin. object was a Mustela frenata Tiahuanaco culture Bolivia. found on animal's skin were preliminarily identified by DNA-based analysis. Subsequently, oil biocidal evaluated parchments inoculated with (Aspergillus tabacinus, Aspegillus tennesseensis, Trichoderma longibrachiatum). Vapour tests conducted Petri dishes parchment specimens assess fungicidal effect components EOs. EOs used this showed tested fungi. oregano be most effective EO vitro three fungal strains. EOs, particularly EO, represents promising green strategy sustainable conservation organic-based cultural assets.
