A Gram-positive, psychrophilic, rod-shaped bacterium, designated strain N-05, was isolated from soil samples collected off King George Island, west Antarctica (6 ° 13′ 31″ S 5 ° 57′ 08″ W). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain N-05 was related to members of the genus and had highest 16S rRNA gene sequence similarity with the type strain of (98.0 %). The temperature range for growth of strain N-05 was 0–23 °C, with optimum growth occurring at 17–18 °C and approximately pH 6.0–8.0. Strain N-05 had MK-7 as the major menaquinone and anteiso-C and C 7 alcohol as major fatty acids. The genomic DNA G+C content was 39.2 mol%. On the basis of phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness data, strain N-05 is considered to represent a novel species of the genus , for which the name is proposed. The type strain is N-05 (=CGMCC 1.6503=JCM 14646).
