Plant Products as Biocides for Conservation of Cultural Asset Sustainable for Human and Environmental Health

In the last decades plants products are increasingly used also in defining innovative procedures for sustainable conservation of cultural heritage. Particularly, essential oils or hydro-alcoholic extracts have been fruitful applied to contrast microbial colonization on organic and inorganic artworks insect infestation (Anobidae) having regard repellent action.
 this paper, from Asteraceae Lamiaceae plant families utilized counteract widespread (bacteria, cyanobacteria, fungi) due their antimicrobial activity. order define adequate concentration correlating it species detected, activity natural is preliminary vitro assayed by Agar Disc Well Plate Diffusion methods. Moreover, an integrated approach based morphological analysis (optical, scanning confocal electron microscopy), cultures (Nutrient Sabouraud agar) molecular investigation (genomic DNA extraction, sequencing sequence analysis) routinely performed identification largest number taxa.
 Besides, enhance different protocols performed, such as Thymus vulgaris directly wooden sculpture surface extract, followed exposure, a dedicated chamber, volatile compound corresponding Essential Oil. other case studies, exposure compounds Crithmum maritmum, Inula critmoides, Origanum vulgare was under controlled vacuum conditions, comparing effects environmental condition exposure. These studies confirm possible use replacing synthetic chemical biocides, full respect human health environment sustainability.
