Strain M-SA3-94T grew optimally at pH 5.0–6.0, 20 °C and in the presence of 1.0 % (w/v) NaCl. Phylogenetic analysis, based on 16S rRNA gene sequences, indicated that strain M-SA3-94T belonged to the genus Nocardioides in the family Nocardioidaceae, clustering with Nocardioides plantarum NCIMB 12834T, Nocardioides ginsengagri BX5-10T, Nocardioides marinquilinus CL-GY44T and Nocardioides lianchengensis D94-1T (with 96.1 %, 95.9 %, 94.5 % and 94.7 % 16S rRNA gene sequence similarity, respectively). The chemotaxonomic properties of strain M-SA3-94T were similar to those of members of the genus Nocardioides with validly published names. The major fatty acid was iso-C16 : 0. The polar lipid pattern contained diphosphatidylglycerol, phosphatidylglycerol and three unknown phospholipids. The diagnostic diamino acid in the cell-wall peptidoglycan was ll-2, 6-diaminopimelic acid. MK-8(H4) was the predominant menaquinone and the DNA G+C content of this strain was 66.7 mol%. On the basis of these phenotypic, phylogenetic and chemotaxonomic data, strain M-SA3-94T represents a novel species of the genus Nocardioides, for which the name Nocardioides antarcticus sp. nov. is proposed. The type strain is M-SA3-94T ( = CCTCC AB2014053T = LMG 28254T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.000309
