| Outline of Final Research Achievements |
To characterize airborne bacterial and eukaryotic communities, the DGGE analysis of 16S rRNA and 18S rRNA genes amplified by PCR was performed for air samples collected at a suburban site (University of Toyama) and a high-altitude site (Mt. Jodo) in Toyama. The airborne bacterial communities were significantly different between suburban and high-altitude sites. In contrast, the eukaryotic communities appeared to be similar between the two sites. Moreover, three red-pigmented bacterial isolates from air showed resistance to ultraviolet (UV-B and UV-C), desiccation, and hydrogen peroxide. These bacteria could have a built-in advantage for survival in the atmosphere.
