An orange pigmented, non-motile, coccoid bacterial strain, TR0125, was isolated from dust samples collected in the high atmosphere above Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that it was within the radiation of species. Major peptidoglycan amino acids were D-glutamic acid, glycine, D-alanine, L-alanine and ornithine. Predominant fatty acids were 17:0 iso, iso 17:1 9c and 15:0 iso. Strong resistance to desiccation, UV-C and -radiation, high DNA G+C content also supported the affiliation of strain TR0125 to the genus . TR0125 had a highest similarity value (95.7 %) of the 16S rRNA gene sequence to the type strain of the species , and phylogenetic analysis shows that it was further separated from than from , indicating that strain TR0125 was not a member of these two species. Besides, there were phenotypic differences between strain TR0125 and type strains of the two species. Therefore, we propose a new species of the genus , sp. nov. (type strain, TR0125 = JCM 11750 = DSM 21212), to accommodate this isolate.
