Overview:  
 
Abstract: The following master’s thesis deals with the issue of determining a decontamination method for archaeological pottery finds. The chosen method should not lead to a complete breakdown of any proteins from food that might have been preserved on the pottery surface. Ozone, ozone+ionization and UV-C radiation are used as decontamination methods in two consecutive test series. The first test series examines the effect of the respective decontamination method on the growth of four different microorganisms. The selection of microorganisms was made on the basis of previous examinations of pottery finds. The chosen microorganisms are Eurotium amstelodami, Eurotium rubrum, Aspergillus halophilicus and Penicillium chrysogenum. The microbial growth is evaluated after two different time intervals (24 h and 72 h). The second test series evaluates the effect of the three decontamination methods on the protein ovalbumin after the previously used time periods. The concentration of remaining ovalbumin after treatment is detected using the Enzyme-linked Immunosorbent Assay (ELISA). After evaluating both test series, it can be stated that treatment with ozone and ionization is the most suitable decontamination method for archaeological pottery finds.
