Abstract

Growing interest is now addressed to using essential oils (EOs) as antimicrobial substances, in medical, industrial, food, and many other sectors. Oregano and thyme EOs are among the most effective oils and, for this reason, they have also been investigated in the field of cultural heritage. This work reports some preliminary results of a new approach for monitoring in-situ the biocide action on biological patinas by a fast analysis based on bioluminescence. In this research, we evaluated the efficacy of a commercial biocide based on EOs, in comparison with common commercial biocides containing hazardous formulations for human health and environment. Keywords: essential oil; biocide; Origanum spp. oil; bioluminescence; biological patina cleaning; historical buildings.
