| Popis: | Microbial sampling was conducted in the stratosphere above Pacific Ocean adjacent to Japan Main Island by using a balloon in June 2005. Air was filtrated by membrane filters during sampling. Totally 4 isolates were obtained from the membrane filters incubated on culture medium. From their morphological characteristics, UV resistance and 16S rDNA sequencing data, the isolates appeared to be endospore-forming bacteria of terrestrial origin (3 Bacillus strains and 1 Paenibacillus strain). Endospores are known to have higher UV-resistance than vegetative cells. The isolation of endospore-forming bacterial species is associated with the high UV level in the stratosphere. 形態: カラー図版あり 資料番号: AA0064301002 レポート番号: JAXA-RR-08-001 |
