The isolate formed milky-white colonies comprising aerobic, Gram-stain-positive, rod-shaped cells. Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the organism belonged to the genus Nocardioides and consistently formed a distinct cluster with Nocardioides agariphilus JCM 16020T and Nocardioides islandensis MSL 26T, sharing 95.5 and 94.8 % 16S rRNA gene sequence similarities, respectively. The genomic DNA G+C content was 69.9 mol%. Chemotaxonomically, the isolate contained ll-diaminopimelic acid in the cell-wall peptidoglycan, MK-8 (H4) as the predominant menaquinone, and diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol as the polar lipids found in the cell wall. The major fatty acids were 18 : 1 ω9c (38.6 %), 16 : 0 iso (20.3 %), 15 : 0 iso (6.8 %) and 18 : 0 (5.8 %). Based on its physiological, biochemical and chemotaxonomic characteristics, the strain represents a novel species of the genus Nocardioides , for which the name Nocardioides taihuensis sp. nov. (type strain X17T=CGMCC 4.7318T=NBRC 112321T) is proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002163
