An orange-pigmented, non-motile, coccoid bacterial strain, designated TR0125^T, was isolated from dust samples collected in the high atmosphere above Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was within the radiation of Deinococcus species. The major peptidoglycan amino acids were D-glutamic acid, glycine, D-alanine, L-alanine and ornithine. The predominant fatty acids were iso-C_{17 : 0}, iso-C_{17 : 1}9c and iso-C_{15 : 0}. Strong resistance to desiccation, UV-C and gamma radiation and high DNA G+C content also supported the affiliation of strain TR0125^T to the genus Deinococcus. Strain TR0125^T showed the highest 16S rRNA gene sequence similarity value (95.7 %) to the type strain of Deinococcus apachensis, and phylogenetic analysis showed that it was further separated from D. apachensis than from Deinococcus geothermalis, indicating that strain TR0125^T was not a member of these two Deinococcus species. In addition, phenotypic differences were found between strain TR0125^T and the type strains of these two Deinococcus species. Therefore, a novel species of the genus Deinococcus, Deinococcus aerius sp. nov. (type strain, TR0125^T=JCM 11750^T=DSM 21212^T), is proposed to accommodate this isolate.

Tables showing the differential characteristics and fatty acid compositions of strain TR0125^T and the type strains of closely related Deinococcus species are available as supplementary material with the online version of this paper.
