We have investigated the possibility of application of akanols in order to protect ancient wall paintings from fungal contamination. In this study, the antifungal activities of isomers of alkanols in agar gel phase were examined and compared those with the activities of n-alkanols. The objective fungi used were xerotolerant Aspergillus niger and Penicillium funiculosum and xerophilic Aspergillus restrictus and Eurotium amstelodami and, as alkanols, ethanol (EtOH), n-propanol (n-PrOH), n-butanol (n-BuOH), n-pentanol (n-PeOH), 2-propanol (2-PrOH) , 2-butanol (2-BuOH), t-butanol (t-BuOH), 2-pentanol (2-PeOH), 3-pentanol (3-PeOH) and t-amyl alcohol (t-AmOH) were employed in this study. The kinetics of fungal growth were analyzed by using two empirical equations, one of which expresses the relationship between the colony area and the treatment time and the other of which does that between the inhibition percentage of fungal growth and the alkanol concentration. From the former relationship, the growth rate a was calculated and, the second parameter β indicating the dependency of the percentage of growth inhibition, which was obtained from a value, upon the alkanol concentration was calculated using the latter relationship. Further, from the latter relationship, the inhibitory concentration indices, IC₀, IC₅₀ and IC₁₀₀, were obtained and used to compare the antifungal activity among different alkanol isomers. We concluded by evaluating these parameters and indices that n-pentanol was the most effective among tested alkanols and secondary and tertiary alkanols were not as much powerful as primary alkanols. We also suggested that the hydrophobicity of alkanol molecule is the key factor for the growth inhibitory ability of alkanol, although we could not determine whether the surface hydrophobicity of fungal colony mat or spore had some substantial effect on the antifungal activity of alkanols. Based upon the results obtained in this study, we propose the potential use of n-pentanol possibly as a vapor for the protection of mural paintings from fungal contamination. |
