| Research Abstract |
The objective of this study is to test an quantitative analytic method for airborne ice nucleating bacteria. By the laboratory experiments, it was confirmed that the ice nucleating activity of Pseudomonas syringae (Snowmax: artificial snow inducer) was decreased by the heat treatment at low temperature. This heat sensitivity of ice nucleating bacteria is different from the sensitivities of other ice nuclei. It was also observed that the numbers of ice nuclei in fresh snow were decreased by the heat treatment at low temperature. This suggests that the heat sensitivity at low temperature may be one of the indicator for the quantitative detection of airborne ice nucleating bacteria.
