Abstract
An aerobic, Gram-stain-positive, non-motile, dull-yellow, short rod-shaped actinomycete strain, designated G10T, was isolated from Tagetes patula (marigold) roots collected from Goyang in the Republic of Korea. The isolate showed best growth on Reasoner's 2A agar at 25 °C, pH 6.5.0 and with 0% NaCl (w/v). The strain was negative for oxidase activity and positive for catalase activity. On the basis of 16S RNA gene sequence similarity, strain G10T was affiliated to the genus Nocardioides and the closest species were Nocardioides glacieisoli HLT3-15T (98.8 %), Nocardioides zhouii HLT2-9T (98.8 %), Nocardioides ganghwensis JC2055T (98.7 %), Nocardioides cavernae YIM A1136T (98.6 %), Nocardioides flavus Y4T (98.5 %), Nocardioides oleivorans DSM 16090T (98.3 %), Nocardioides alpinus Cr7-14T (98.2 %), Nocardioides exalbidus DSM 22017T (98.1 %) and Nocardioides hwasunensis KCTC 19197T (98.1 %). Strain G10T formed a monophyletic cluster with N. glacieisoli HLT3-15T, N. zhouii HLT2-9T and N. hwasunensis KCTC 19197T in all phylogenetic trees. The cell-wall peptidoglycan of strain G10T contained ll-diaminopimelic acid as the diagnostic amino acid. The predominant fatty acids were iso-C16 : 0 and C17 : 1 ω8c. MK-8(H4) was the major isoprenoid quinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol. Average nucleotide identity and digital DNA-DNA hybridization values were 78.6-88.7 % and 21.5-36.2 %, respectively, with the type strains of related species of the genus Nocardioides, suggesting that strain G10T represents a novel species. The genome of strain G10T is 4 231 000 bp long with a DNA G+C content of 71.5 mol% and encodes 4071 predicted proteins, six rRNAs and 46 tRNAs. The genome of strain G10T comprises the biosynthetic gene cluster for T3PKS, terpene, NRPS-like fragment and RRE-containing element as secondary metabolites. The results of taxonomic, phylogenetic, biochemical, chemotaxonomic and genomic analysis clearly supported that strain G10T represent a novel species within the genus Nocardioides, for which the name Nocardioides baculatus sp. nov is proposed and the type strain is G10T (=KCTC 49626T=NBRC 114801T).

Abstract
Two novel Gram-stain-positive, irregular rod-shaped actinomycetes, S-1144T and 4053, were isolated from leaves of Lamiophlomis rotata on the Qinghai-Tibet Plateau, PR China. Cells were aerobic, catalase-positive and oxidase-negative. Colonies on Reasoner's 2A agar were light yellow, circular, shiny, smooth and convex after 2 days of incubation. The isolates grew optimally at 25 °C, pH 7.5 and with 0 % (w/v) NaCl. The results of polyphasic analyses indicated that strain S-1144T belonged to the genus Nocardioides and its close phylogenetic neighbours (16S rRNA gene sequence similarity) were Nocardioides litoris DSM 103718T (98.4 %), Nocardioides rubriscoriae DSM 23986T (98.2%) and Nocardioides plantarum DSM 11054T (97.8 %). The genome of strain S-1144T showed less than 70 % digital DNA-DNA hybridization and < 95-96 % average nucleotide identity values to the above reference strains. The DNA G+C content of strain S-1144T was 73.5 mol%. MK-8(H4) was the predominant respiratory quinone (96.0 %) and llLL-2,6-diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The polar lipid profile of strain S-1144T consisted of diphosphatidylglycerol, phosphatidylglycerol, three unidentified phospholipids, one unidentified glycolipid and one unidentified lipid. The major cellular fatty acids were iso-C16 : 0, C17 : 1 ω8c, C17 : 0 and C18 : 1 ω9c. On the basis of obtained data, strain S-1144T represented a novel species of the genus Nocardioides, for which the name Nocardioides dongxiaopingii sp. nov. is proposed. The type strain is S-1144T (=CGMCC 4.7568T=JCM 33469T).

Nocardioides jejuensis sp. nov., isolated from soil. Antonie van Leeuwenhoek 2019; 113:339-347.

Abstract
A Gram-stain positive, asporogenous, aerobic, white -coloured bacterium, designated 18JY15-6T, was isolated from soil from Jeju Island, Korea. Pairwise analysis of the 16S rRNA gene sequence of strain 18JY15-6T indicated high similarity to Nocardioides phosphati DSM 104026T (97.4%), Marmoricola terrae KACC 17308T (96.7%) and Nocardioides jensenii KCTC 0074BPT (96.6%). Phylogenetic analysis revealed that strain 18JY15-6T formed a distinct lineage within the family Nocardioidaceae and is closely related to members of the genus Nocardioides. Genome sequencing of strain 18JY15-6T revealed 3221 total genes, including 3162 protein coding genes, 59 RNA and 31 pseudogenes. Growth was observed at 18-37 °C (optimal 30 °C) in R2A medium at pH 7.0. The major cellular fatty acids of strain 18JY15-6T were identified as C16:0, C18:1ω9c, C18:0 10-methyl, tuberculostearic and C17:0. The fatty acid profile of strain 18JY15-6T was more dissimilar when compared with M. terrae. The only respiratory quinone present was found to be MK-8(H4). The major polar lipids are diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. The results of phylogenetic, biochemical and chemotaxonomic characterisation allow the differentiation of strain 18JY15-6T from N. phosphati WYH11-7T, M. terrae JOS5-1T and N. jensenii NBRC 14755T which supports the conclusion that this strain represents a novel species of the genus Nocardioides, for which we propose the name Nocardioides jejuensis sp. nov. The type strain of Nocardioides jejuensis is 18JY15-6T (= KCTC 49105T = JCM 33182T).

Abstract
A novel actinobacterial strain, designated YIM A1136T, was isolated from a soil sample collected from a karst cave in Xingyi county, Guizhou province, south-western China. The taxonomic position of the strain was investigated using a polyphasic approach. Cells of the strain were aerobic, Gram-staining-positive and rod-shaped. Colonies of the strain were circular, convex, opaque and yellowish-white in colour. On the basis of 16S rRNA gene sequence analysis, strain YIM A1136T was most closely related to the type strains Nocardioides ganghwensis JC2055T (98.3 % sequence similarity), Nocardioides exalbidus RC825T (98.2 %), Nocardioides alpinus Cr7-14T (98.2 %), Nocardioides hwasunensis HFW-21T (98.0 %), Nocardioides oleivorans DSM 16090T (97.9 %) and Nocardioides furvisabuli SBS-26T (97.8 %) and is therefore considered to represent a member of the genus Nocardioides. DNA-DNA hybridization values between strain YIM A1136T and related type strains of the genus Nocardioides were less than 70 %. ll-Diaminopimelic acid was the diagnostic diamino acid in the cell-wall peptidoglycan. The whole-cell sugars were galactose, glucose, mannose, rhamnose and ribose. The major isoprenoid quinone was MK-8(H4), while the major fatty acids (>10 %) were C16 : 0, summed feature 3 and summed feature 8. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and two unidentified phospholipids. The genomic DNA G+C content was 71.4 mol%. On the basis of phenotypic, genotypic and phylogenetic data, strain YIM A1136T merits representation of a novel species of the genus Nocardioides, for which the name Nocardioides cavernae sp. nov. is proposed. The type strain is YIM A1136T (=KCTC 39551T=DSM 29950T).
