Nocardioides antarcticus sp. nov., isolated from marine sediment Deng, Sangsang and Chang, Xulu and Zhang, Yumin and Ren, Lvzhi and Jiang, Fan and Qu, Zhihao and Peng, Fang,, 65, 2615-2621 (2015), doi = https://doi.org/10.1099/ijs.0.000309, publicationName = Microbiology Society, issn = 1466-5026, abstract= Strain M-SA3-94T, an aerobic, Gram-stain-positive, ovoid- to rod-shaped, non-motile bacterium, was isolated from the marine sediment of Ardley cove, King George Island, Antarctica. 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)., language=, type=
