内容記述 |
Cultural properties including mural paintings, ancient papers and documents, and historical stones are often contaminated with various fungi. To protect such valuable properties from fungal growth, we investigated the effects of gamma ray irradiation on the spores of Aspergillus restrictus as a xerophilic fungus and Aspergillus brasiliensis as a xerotolerant fungus. Paper disks containing approximately 100 fungal spores were irradiated with gamma ray at doses between 0.2 and 2.5 kGy and then placed on agar plates. During the cultivation of those plates at 25℃ for seven days, the diameters of the colonies on each paper disk were measured to calculate colony areas as the parameter A(mm²). The increase in A was apparently proportional to the cultivation day after an apparent lag period. Notably, the antifungal effect of gamma irradiation did not represent the delay of the initiation of growth, but the suppression of the growth rate after growth initiation. By comparing the rates of increase of the colony areas for unirradiated and irradiated spore samples, the percentage of growth inhibition was estimated to compare the radiation sensitivity of the two fungi. Consequently, A. restrictus was found to be more sensitive to gamma irradiation than A. brasiliensis. On the basis of these results, the growth kinetics of radiation-injured fungal spores as a fundamental aspect and the possibility of utilization of irradiation for the decontamination of cultural properties as an application aspect were discussed. |
