Abstract
There is a new described antifungal system (GALVI) involving the moving of bioactive ions of Zn, Cu and Bi for the protection of cultural heritage objects such as buildings, sculptures and stretchers. There were two kinds of galvanic cells that were used: the first composed of a two-electrodes system, Zn, Cu, and second one composed of a three-electrodes system, Zn, Bi and Cu. Moreover, two-phase media are proposed with various kinds of rocks used in architectonical objects. Microorganisms inhabit the boundaries of two liquid and solid phases. This enables the investigation of the process of rock colonization. Possible applications of the suggested GALVI system are mentioned.
Highlights
Cultural heritage contains buildings and mines, caves, graves, old canals, bridges, ships, boats, historical glass, ceramics, sculptures, and artistic painting
Various microorganisms are involved in the biodeterioration of the architecture objects
Fungi can cause the biodeterioration of stone elevations, surfaces, various kinds of monuments, buildings, sculptures, and other objects made of stone as well as wooden elements, artistic paintings, and even concrete walls [38]
Summary
Andrzej Chlebicki 1, *, Wojciech Spisak 2 , Marek W. Using paint with Zn, Bi, Cu (three electrode systems) for covering the lower side of the stretchers is suggested. Two-phase media with SNA (synthetic low-nutrient agar) medium + sterile grandiorite, melabasanite, sandstone, marl and sodium glass (as control) were used. This enables the investigation of the processes of colonization, course, and development of selected microorganisms in the emerging rock microhabitats (patent pending). A dark or even black rock (i.e., melabasanite) exposed to solar radiation heats up much more than a light or even white one In this particular case, granodiorite is light gray, sandstone is beige, and marl is pale beige.
