Abstract
A Gram-stain-negative, motile (by single polar flagellum) and rod-shaped bacterium, designated W1-6T, was isolated from a sediment of drainage ditch in winery in Guiyang, south-western China. Strain W1-6T showed the highest 16S rRNA gene sequence similarities with the type strain of Acidovorax wautersii (98.1%) and Simplicispira lacusdiani (97.9%). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain W1-6T was placed adjacent to the members of the genus Simplicispira and formed a separat subclade. Cells showed oxidase and catalase negative reactions. The only respiratory quinone detected was ubiquinone-8 (Q-8). Summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), C16:0 and summed feature 8 (C18:1 ω7c and/or C18:1 ω6c) were predominant cellular fatty acids (> 10%) of strain W1-6T. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and five unidentified phospholipids were found in the polar lipid extraction. The genomic DNA G + C content was 65.6%. Strain W1-6T shared the highest digital DNA-DNA hybridization [dDDH, (27.6%)] and average nucleotide identity [ANI (84.3%)] values with the type strain of S. lacusdiani. The dDDH and ANI values were below the cutoff level (dDDH 70%; ANI 95-96%) for species delineation. The polyphasic characteristics indicated that the strain W1-6T represents a novel species of the genus Simplicispira, for which the name Simplicispira sedimenti sp. nov. is proposed. The type strain is W1-6T (= CGMCC 1.16274T = NBRC 115624T).

Abstract
Three aerobic, rod-shaped actinobacterial strains, designated MMS17-SY117T, MMS17-SY207-3T and MMS17-SY213T, were isolated from soil and their taxonomic positions were analysed using a polyphasic approach. The isolates showed best growth at 30 °C, pH 7 and 0-1 % (w/v) NaCl. On the basis of 16S rRNA gene sequence similarity, the isolates were affiliated to the genus Nocardioides, and the closest species to MMS17-SY117T, MMS17-SY207-3T and MMS17-SY213T were Nocardioides aestuarii JC2056T (97.76%), Nocardioides currus IB-3T (97.41%) and Nocardioides exalbidus RC825T (98.71%), respectively. Each isolate formed a distinct cluster within the Nocardioides clade in the phylogenetic tree. The orthologous average nucleotide identity and digital DNA-DNA hybridization values were in the range of 74.4-85.7 % and 16.6-39.2 %, respectively, with the type strains of related species. The major polar lipids in all three strains were phosphatidylinositol, phosphatidylglycerol and diphosphatidylglycerol. The predominant fatty acids were iso-C16 : 0 and C17 : 1 ω8c. MK-8(H4) was the major isoprenoid quinone and ll-DAP was the major diamino acid. Galactose, glucose and rhamnose were present in the whole-cell hydrolysate, and MMS17-SY213T also contained mannose and ribose. The DNA G+C contents of MMS17-SY117T, MMS17-SY207-3T and MMS17-SY213T were 72.2, 70.4 and 71.5 mol%, respectively. The phylogenetic, phenotypic and chemotaxonomic data supported the classification of each strain as representing a new species of Nocardioides, for which the names Nocardioides euryhalodurans sp. nov. (MMS17-SY117T=KCTC 49175T=JCM 32831T), Nocardioides seonyuensis sp. nov. (MMS17-SY207-3T=KCTC 49176T=JCM 32832T) and Nocardioides eburneiflavus sp. nov. (MMS17-SY213T=KCTC 49177T=JCM 32833T) are proposed accordingly.

Abstract
A mycolic acid-containing actinobacterium designated strain MMS17-SY073T was isolated from island soil. The isolate showed best growth at 25 °C, pH 6, and 0 % (w/v) NaCl. The phylogenetic analysis based on 16S rRNA gene sequences indicated that strain MMS17-SY073T belongs to the genus Gordonia, and is mostly related to the type strains of Gordonia soli (98.5 % sequence similarity), Gordonia polyisoprenivorans (98.1%), and Gordonia hankookensis (97.8%). The genome-based comparisons showed a clear distinction between the strain and the two neighbouring species, G. soli and G. polyisoprenivorans, with the average nucleotide identities (ANI) of 75.8 and 76.3 %, respectively. Notably, the genome of strain MMS17-SY073T was the largest in total stretch and gene counts among the complete genomes of Gordonia, and contained a number of biosynthetic gene clusters for secondary metabolites, in particular those for non-ribosomal peptide synthetases. The major polar lipids were diphosphatidyl glycerol (DPG), phosphatidyl glycerol (PG), phosphatidyl ethanolamine (PE), phosphatidyl inositol (PI) and phosphatidyl inositol mannoside (PIM). The isoprenoid quinone was MK-9(H2), and the main fatty acids were C16 : 0 (30.2%) and 10-methyl-C18 : 0 (33.7%). The whole cell hydrolysates contained galactose, arabinose, and meso-diaminopimelic acid. The DNA G+C content was 67.4 mol%. Based on phenotypic, chemotaxonomic and genetic analysis, strain MMS17-SY073T should be classified as a new species of the genus Gordonia, for which the name Gordonia insulae sp. nov. is proposed (type strain=MMS17-SY073T=KCTC 49257T=JCM 33277T).
