Abstract: The influence of the environment on the artefacts often translates (in absence of protecting measures) into their damage trough physical, chemical or biological processes. Most artefacts (regardless of their nature) are affected by the action of fungi. Previously it was shown that the most widespread fungi are those of Aspergillus sp. and Penicillium sp.
Developing new bioremediation recipes based on synthesized chemical substances (with low or absent toxicity for humans and to the rest of the environment) can remove the shortcomings of the currently used methods (gamma or UV irradiation, etc.).
This paper presents the synthesis and characterization of new materials (hydroxyapatite and its derivatives, hydroxides of alkaline earth metals). Characterization of the synthesized materials was performed using state-of-the-art analytical techniques (XRD, XRF, FTIR, thermal analysis). Characterization in terms of antifungal action was performed using the diluted inoculum technique on culture media. The obtained results allow us to hope for an alternative method for the removal of biodegradation, using selected synthesized materials.
