“…Rosado et al [35] demonstrated that different bacterial and fungal taxa display distinctive sensitivity to different biocides. The different solvents and biocidal products affected in a specific manner the growth and/or the pigmentation of the four fungal taxa isolated from the sacristy vault of a religious building [18]. Evaluating the effects of the biocide Rohm and Haas Rocima™ 103, Urzì et al [22] showed that the biocidal treatment had a limited effect on cyanobacteria and strongly decreased community biodiversity.…”

Aesthetic Alteration of Marble Surfaces Caused by Biofilm Formation: Effects of Chemical Cleaning

et al. 2020

Despite the massive presence of biofilms causing aesthetic alteration to the façade of the Monza Cathedral, our team in a previous work proved that the biocolonization was not a primary damaging factor if compared to chemical-physical deterioration due to the impact of air pollution. Nonetheless, the conservators tried to remove the sessile dwelling microorganisms to reduce discolouration. In this research, two nearby sculpted leaves made of Candoglia marble were selected to study the effects of a chemical treatment combining the biocides benzalkonium chloride, hydrogen peroxide and Algophase® and mechanical cleaning procedures. One leaf was cleaned with the biocides and mechanically, and the other was left untreated as control. The impact of the treatment was investigated after 1 month from the cleaning by digital microscopy, environmental scanning electron microscopy, confocal microscopy and molecular methods to determine the composition and the functional profiles of the bacterial communities. Despite the acceptable aesthetic results obtained, the overall cleaning treatment was only partially effective in removing the biofilm from the colonized surfaces and, therefore, not adequately suitable for the specific substrate. Furthermore, the cleaning process selected microorganisms potentially more resistant to biocides so that the efficacy of future re-treatment by antimicrobial agents could be negatively affected.

“…Menthol is a naturally occurring cyclic monoterpene alcohol existing in many plants, which may also have an antifungal ability. Penicillium and Aspergillus are common fungi species [31][32][33] and are often observed in archaeological excavations [34,35]. Thus, they were chosen to explore the antifungal evaluation of menthol coating on mock-ups in laboratory.…”

Once excavated, cultural relics face immediate threats from oxidation, water loss, mold growth, etc., which are caused due to severe environmental changes. Covering with plastic films, spraying water, or applying biocides followed by mechanical polish are common conservation practices, which are effective to some extent, but with obvious side effects. Menthol, often used as volatile binding material (VBM) in heritage conservation, has been proved to be safe to conservators and cultural relics and can be removed easily via sublimation with no residue. In this study, the possibility of using menthol coatings as a reversible environmental barrier to protect cultural relics during excavation is examined. Laboratory results show that menthol coating has an excellent ability to prevent oxygen and water molecules from passing through it, to stop various fungal growths and cut off radiation below 300 nm. On-site antifungal applications on a mural tomb of the Tang Dynasty, located in the north of Xi’an Xianyang International Airport, provided satisfactory results. Laboratory and field results show that menthol coating has high potential of being used for the emergency protection of relics against sudden environmental changes during excavation.

“…Quaternary ammonium compounds are widely used as antiseptics and disinfectants in medical and industrial fields (Gilbert and Moore, 2005). In cultural heritage, those components are commonly used during cleaning procedures by professional restorers (Stupar et al, 2014;Favero-Longo et al, 2018). The efficiency of Preventol RI80 was proven in many studies as a curative treatment to eliminate a wide spectrum of microorganisms, such as fungi and bacteria (Blazquez et al, 2000;Maxim et al, 2012).…”

“…The biocidal effect of Preventol RI80 was effective for only three weeks, despite the good antibiocolonisation preventive results of benzalkonium chloride for a longer time as two months in an accelerated growing assay with a mixing of green algae and cyanobacteria (Barriuso et al, 2017). Moreover, Preventol RI80 was efficient on cultural heritage to remove fungi and bacteria (Urzì et al, 2016;Favero-Longo et al, 2018;Li et al, 2020;Rugnini et al, 2020) as well as algae and lichens (Nugari et al, 2009;De los Ríos et al, 2012;Pfendler et al, 2018b). Furthermore, many studies have demonstrated antimicrobial activity for a curative action in a short time in most of case and in a longer time when lichen was previously soaked for 1 h in Preventol RI80 (Coutinho et al, 2016;Vannini et al, 2018).…”
