The results of my research on mould damaged photographs and their disinfection with ethanol just got published in Restorator.
This study deals with mould damaged photographic gelatin disinfection methods. Ethanol is used as an antifungal treatment, with success, in the medical and food industry. A solution of deionised water and absolute ethanol (30:70 v/v) mixture has been shown as the most efficient. The goal of this study was to determine a suitable method to apply this mixture in order to obtain a biocide effect. Three implementations were tested: solvent chamber, direct contact and direct contact followed by a mechanical removal. Different treatment times were tested for each method. The tests were done on four fungal strains: Alternaria alternata, Aspergillus niger, Chaetomium globosum and Penicillium brevicompactum.
The deionized water and absolute ethanol mixture, applied for two hours in a solvent chamber, succeeded in inactivating the four tested fungal strains.
