The strain was Gram-staining- and catalase-positive and contained lysine and alanine in the cell-wall peptidoglycan. The major cellular fatty acids were anteiso-C15 : 0 (54.92 %), iso-C15 : 0 (11.47 %), anteiso-C17 : 0 (6.48 %) and anteiso-C15 : 1 (6.38 %) and the major menaquinones were MK-8, MK-9 and MK-10. The major polar lipids were phosphatidylethanolamine and diphosphatidylglycerol. The G+C content was 68±0.5 mol%. Based on 16S rRNA gene sequence similarities, the nearest phylogenetic neighbours of strain SPC26T were identified as Arthrobacter gangotriensis Lz1yT (98.8 %), A. sulfureus DSM 20167T (98.6 %), A. psychrophenolicus DSM 15454T (97.9 %) and A. kerguelensis KGN15T (97.5). With these strains, strain SPC26T exhibited DNA–DNA relatedness values of 36, 21, 12 and 10 %, respectively. Therefore, on the basis of 16S rRNA gene sequence comparisons, phylogenetic analysis, phenotypic characteristics and DNA–DNA relatedness, it is proposed that strain SPC26T represents a novel species of Arthrobacter, for which the name Arthrobacter antarcticus sp. nov. is proposed, with strain SPC26T (=LMG 24542T =NCCB 100228T) as the type strain. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.012989-0
