A Gram-positive, psychrophilic, rod-shaped bacterium, designated strain N-05^T, 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^T was related to members of the genus Sporosarcina and had highest 16S rRNA gene sequence similarity with the type strain of Sporosarcina macmurdoensis (98.0 %). The temperature range for growth of strain N-05^T was 0–23 °C, with optimum growth occurring at 17–18 °C and approximately pH 6.0–8.0. Strain N-05^T had MK-7 as the major menaquinone and anteiso-C_{15 : 0} and C_{16 : 1}7c 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^T is considered to represent a novel species of the genus Sporosarcina, for which the name Sporosarcina antarctica is proposed. The type strain is N-05^T (=CGMCC 1.6503^T=JCM 14646^T).

A table detailing the cellular fatty acid content of strain N-05^T in comparison with other recognized Sporosarcina species is available as supplementary material with the online version of this paper.
