Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, Terrestrial microbes may be ejected to outer space by natural events such as volcanic eruption, meteorite impact and electrostatic interactions. Microbes have been collected at high altitude up to several tens km using balloons and aircrafts. Some of the sampled microbes showed the high UV-resistance. To test the possible interplanetary migration of terrestrial life, we propose the microbe sampling experiments on International Space Station (ISS) at low Earth orbit (400 km). Ultra low-density aerogel will be exposed to space to capture micro-particles. After the curation of tracks and particles on the aerogel, the samples will be distributed to scientists to examine mineralogical, organo-chemical and microbiological characteristic of the particles. For the microbiological analysis, samples will be stained with DNA-specific fluorescence-pigment, and will be inspected with a fluorescence microscope. The fluorescent particles will be used for PCR amplification of the rRNA sequence followed by cloning and DNA sequencing. The sequence will be used to estimate the origin and properties of the captured microbes., 著者人数: 21人, Number of authors: 21, 資料番号: AA0065129069}, pages = {185--188}, publisher = {宇宙航空研究開発機構宇宙科学研究所 (JAXA)(ISAS), Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)}, title = {有機物・微生物の宇宙曝露と宇宙塵・微生物の捕集: たんぽぽ}, volume = {27}, year = {2011} }
