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-FR2-10T (93.5 %), Deinococcus xinjiangensis X-82T (92.8 %), Deinococcus indicus Wt/1aT (92.5 %), Deinococcus daejeonensis MJ27T (92.3 %), Deinococcus wulumuqiensis R-12T (92.3 %), Deinococcus aquaticus PB314T (92.2 %) and Deinococcus radiodurans DSM 20539T (92.2 %). Major fatty acids were C18 : 1ω7c, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), anteiso-C15 : 0 and C16 : 0. The G+C content of the genomic DNA of strain G3-6-20T was 63.1 mol%. Menaquinone 8 (MK-8) was the predominant respiratory quinone. Based on its phylogenetic position, and chemotaxonomic and phenotypic characteristics, strain G3-6-20T represents a novel species of the genus Deinococcus , for which the name Deinococcus antarcticus sp. nov. is proposed. The type strain is G3-6-20T ( = DSM 27864T = CCTCC AB 2013263T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.066324-0
