Paper Abstract

When speaking of sensitive artifacts, control of the environmental conditions seems to be the best means of protecting theme. In theory, for a well preserved and uninfected artifact the best way to prevent fungal growth is to protect surfaces from contamination, control moisture and relative humidity (RH). For already biodeteriorated or fungus-infected artifacts, several methods, such as vacuum cleaning, freezing, heat treatment, chemicals, altered atmospheric gases or radiation, could be used. Realistically speaking, these methods often cannot be applied for some disadvantage of their use or because their high cost. This is why the aim of our research is to propose alternative chemical methods, based on natural extracts and/or synthetic chemical compounds for the removal of fungus from affected artifacts. To obtain remediation of the biodeterioration of the artifacts, we used mixtures of hydroxyapatite and alkali-metals hydroxides dispersed in isopropyl alcohol. An example of the treatment effectiveness is presented, using a selected recipe. Also, natural extracts were evaluated for their use in the bioremediation of the artifacts.
