Abstract:
A pink-pigmented, non-motile, coccoid bacterial strain, designated G3-6-20 T , was isolated from a soil sample collected in the Grove Mountains, East Antarctica. This strain was resistant to UV irradiation (810 J m −2 ) and slightly more sensitive to desiccation as compared with Deinococcus radiodurans . Phylogenetic analyses based on the 16S rRNA gene sequence of the isolate indicated that the organism belongs to the genus Deinococcus . Highest sequence similarities were with Deinococcus ficus CC-FR2-10 T (93.5 %), Deinococcus xinjiangensis X-82 T (92.8 %), Deinococcus indicus Wt/1a T (92.5 %), Deinococcus daejeonensis MJ27 T (92.3 %), Deinococcus wulumuqiensis R-12 T (92.3 %), Deinococcus aquaticus PB314 T (92.2 %) and Deinococcus radiodurans DSM 20539 T (92.2 %). Major fatty acids were C 18 : 1 ω7 c , summed feature 3 (C 16 : 1 ω7 c and/or C 16 : 1 ω6 c ), anteiso-C 15 : 0 and C 16 : 0 . The G+C content of the genomic DNA of strain G3-6-20 T was 63.1 mol%. Menaquinone 8 (MK-8) was the predominant respiratory quinone. Based on its phylogenetic position, and chemotaxonomic and phenotypic characteristics, strain G3-6-20 T represents a novel species of the genus Deinococcus , for which the name Deinococcus antarcticus sp. nov. is proposed. The type strain is G3-6-20 T ( = DSM 27864 T = CCTCC AB 2013263 T ).
