Abstract

A pink-pigmented, non-motile, coccoid bacterial strain, designated G3-6-20, was isolated from a soil sample collected in the Grove Mountains, East Antarctica. This strain was resistant to UV irradiation (810 J m) and slightly more sensitive to desiccation as compared with . Phylogenetic analyses based on the 16S rRNA gene sequence of the isolate indicated that the organism belongs to the genus . Highest sequence similarities were with CC-FR2-10 (93.5 %), X-82 (92.8 %), Wt/1a (92.5 %), MJ27 (92.3 %), R-12 (92.3 %), PB314 (92.2 %) and DSM 20539 (92.2 %). Major fatty acids were Cω7, summed feature 3 (Cω7 and/or Cω6), anteiso-C and C. The G+C content of the genomic DNA of strain G3-6-20 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 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is G3-6-20 ( = DSM 27864 = CCTCC AB 2013263).
