Travertine is a sedimentary carbonate rock widely used in Roman arts and frequently subjected to biodeterioration. In this preliminary multi-analytical study, three essential oils (EOs) from T. vulgaris, O. vulgare, C. nepeta and their respective phenolic major components (thymol, carvacrol, pulegone) were selected to evaluate their biocidal potential against a multi-species biofilm grown on a travertine test wall located inside Sapienza University Campus in Rome. A preliminary characterization of the biofilm occurred through the employment of genomic methodologies.

Tansy daisy (Tanacetum macrophyllum (Waldst. et Kit.) Schultz Bip., Asteraceae) is a perennial herb worldwide cultivated for ornamental and industrial purposes. Sometimes, this species is misidentified by herb collectors and botanists with its family mate Achillea grandifolia (white yarrow). In the present work, we have analysed the essential oil and ethanolic extract obtained from the aerial parts of tansy daisy cultivated in Italy and evaluated the biological activity in terms of cytotoxic, antioxidant and anticholinesterase activities.
