As model systems for the protection of cultural properties from fungal contamination, the suppressive effects of gamma-ray irradiation at low doses on the viability of and the development from Aspergillus niger conidiospores were investigated using liquid and solid agar media. In the liquid system, after irradiation at relatively low doses (0.2 kGy and 0.4 kGy) and the subsequent cultivation at 25℃ in potato dextrose broth (PDB), the rate of development of A. niger from spores, as measured by the increase in optical density at 600 nm (OD₆₀₀) of the culture, decreased in a dose dependent manner, but the initiation of active growth was not delayed. Irradiation at relatively high doses (above 0.6 kGy and 0.8 kGy) not only suppressed the growth rate but also substantially delayed the start of active growth. In the solid system, spores developed and formed a colony around a paper disk placed on a plate of potato dextrose agar (PDA). In this analysis, the area rather than the radius of the colony correlated with the cultivation time. Based on this finding, the suppressive effect of irradiation on growth was evaluated. The viability measured using the colony-count method on PDA was clearly lower than the integrated viability measured using the growth delay analysis method in PDB. Microscopic observation demonstrated that irradiated spores were unable to form a colony and swelled at a lower rate than that of unirradiated spores. These results suggest the possible beneficial use of ionizing irradiation for the protection of cultural properties from fungal contamination and deterioration. |
