Toxic substances are often employed in conventional stone preservation techniques, whereas biorestoration offers material compatibility along with significant benefits for cultural heritage preservation, environmental safety, and sustainability. However, the application of this innovative technique to natural rocks is not fully understood. In this study, we evaluated the efficiency of a carbonatogenic bacterial strain (Lysinbacillus fusiformis 3.

- The study focuses on preserving the Etruscan Necropolis of Tarquinia, Italy, which has valuable painted tombs that are threatened by microbial growth.
- Since 2016, researchers have been monitoring fungi in one of the tombs, known as the Tomba degli Scudi, to understand the cause of newly observed black spots on the artwork.
- The findings reveal that the fungal strains discovered are commonly found in similar underground environments, highlighting the importance of ongoing monitoring for successful preservation efforts.
Up to 70 % of the oil paintings conserved in collections present metal soaps, which result from the chemical reaction between metal ions present in the painted layers and free fatty acids from the lipidic binders. In recent decades, conservators and conservation scientists have been systematically identifying various and frequent conservation problems that can be linked to the formation of metal soaps. It is also increasingly recognized that metal soap formation may not compromise the integrity of paint so there is a need for careful assessment of the implications of metal soaps for conservation.
