A novel aerobic, Gram-stain-negative, motile bacterium, designated strain BUT-10T, was isolated from the sludge of a pesticide manufacturing factory in Kunshan, China. Cells were rod-shaped (0.4–0.45×0.9–1.4 µm) and colonies were white, circular with entire edges and had a smooth surface. The strain grew at 25–37 °C, at pH 6.0–8.0 and with 0–0.5 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain BUT-10T was a member of the genus Phenylobacterium , and showed highest sequence similarities to Phenylobacterium muchangponense A8T (97.49 %), Phenylobacterium immobile DSM 1986T (97.14 %) and Phenylobacterium lituiforme FaiI3T (96.34 %). Major fatty acids (>5 %) were summed feature 8 (comprising C18 : 1ω7c and/or C18 : 1ω6c), C16 : 0 and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). The major isoprenoid quinone was ubiquinone-10. The DNA G+C content was 71.85 mol%. Strain BUT-10T showed low DNA–DNA relatedness with P. muchangponense A8T (15.7±2.9 %) and P. immobile DSM 1986T (12.8±1.1 %). On the basis of the phenotypic, phylogenetic and genotypic data, strain BUT-10T is considered to represent a novel species of the genus Phenylobacterium , for which the name Phenylobacterium kunshanense sp. nov. is proposed. The type strain is BUT-10T ( = CCTCC AB 2013085T = KCTC 42014T).

Phospholipid Profile

A Gram-reaction-positive aerobic actinomycete, designated strain MN08-A0118T, which produced short chains of non-motile spores on the tips of long sporophores and formed yellow–brown colonies with branched substrate mycelium, was studied in detail to determine its taxonomic position. On the basis of 16S rRNA gene sequence analyses, strain MN08-A0118T was grouped into the genus Herbidospora , being most closely related to Streptosporangium claviforme (98.2 %), Herbidospora osyris (98.2 %), Herbidospora daliensis (98.2 %), Herbidospora cretacea (97.9 %) and Herbidospora yilanensis (97.4 %). Chemotaxonomic data supported allocation of the strain to the genus Herbidospora . MK-10(H4) was the predominant menaquinone with minor amounts of MK-10(H6), MK-10(H2) and MK-9(H4); the fatty acid profile contained major amounts of iso-C16 : 0, C17 : 0 10-methyl, iso-C14 : 0 and iso-C16 : 0 2-OH; the phospholipid profile contained phosphatidylethanolamine, phosphatidylmethylethanolamine and glucosamine-containing phospholipids; and the whole-cell sugars included ribose, glucose, galactose, madurose and rhamnose (trace). The phylogenetic data, phenotypic and genotypic properties and DNA–DNA hybridization differentiated this strain from its closely related strains, S. claviforme (35–54 % DNA–DNA relatedness), H. osyris (39–51 %), H. daliensis (3–16 %), H. cretacea (34–39 %) and H. yilanensis (34–42 %). Thus, MN08-A0118T represents a novel species of the genus Herbidospora , for which the name Herbidospora mongoliensis sp. nov. is proposed, with MN08-A0118T ( = NBRC 105882T  = VTCC D9-22T) as the type strain. In addition, DNA–DNA hybridization results showed that S. claviforme and H. osyris are synonyms of H. cretacea .

Taxonomic Approach

A non-motile, coccobacillus-shaped and pink pigmented bacterium, designated strain 03SU10-PT, was isolated from wetland freshwater (Woopo wetland, Republic of Korea). Cells were Gram reaction-negative and catalase- and oxidase-positive. The major fatty acids (>10 % of total) were C18 : 1ω7c and summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c). The predominant respiratory lipoquinone was Q-10. The DNA G+C content was 68 mol%. The major polar lipids were phosphatidylethanolamine, phosphatidylcholine and an unknown aminolipid. Spermidine, putrescine and 1,3-diaminopropane were the major polyamines. A phylogenetic tree based on 16S rRNA gene sequence comparisons showed that strain 03SU10-PT formed an evolutionary lineage within the radiation enclosing the members of the genus Roseomonas . The nearest neighbour to the novel strain was Roseomonas stagni HS-69T (96.3 % gene sequence similarity). The evidence provided by the polyphasic taxonomic approach used in this study indicated that strain 03SU10-PT could not be assigned to any recognized species; therefore a novel species is proposed, Roseomonas riguiloci sp. nov., with 03SU10-PT ( = KCTC 23339T = JCM 17520T) as the type strain.

Members of the genus Sneathia are fastidious bacteria that predominantly colonise the female genital tract and are significantly associated with reproductive disorders and genital and neonatal disease. From a taxonomical perspective, the genus only comprises the species Sneathia sanguinegens . Numerous reports on a second species, ‘Sneathia amnii’, have been published, but the name has never been validated. The same is the case for ‘Leptotrichia amnionii’, which was previously shown to belong to the same species as ‘Sneathia amnii’. We studied strains DSM 16631T and DSM 16630, which have been identified and deposited as ‘Leptotrichia amnionii’ previously. At the time of isolation, these strains were found to be most closely related to, but clearly different from, Sneathia sanguinegens based on 16S rRNA gene sequence similarities. Both strains proved to be almost indistinguishable from ‘Sneathia amnii’ based on molecular, morphological and physiological traits. The 16S rRNA gene sequence analysis revealed that strain DSM 16631T was assigned to the genus Sneathia with a sequence similarity of 95.47 % to Sneathia sanguinegens CCUG 41628T, followed by type strains of Caviibacter abscessus (93.03 %), Oceanivirga salmonicida (92.68 %) and Oceanivirga miroungae (91.97 %) as the next closely related members of the Leptotrichiaceae . The novel species was also clearly differentiated from other related taxa by core genome phylogeny, average nucleotide and amino acid identities, in silico DNA–DNA hybridization and MALDI-TOF MS. With respect to chemotaxonomic and physiological patterns, strains DSM 16631T and DSM 16630 were again highly similar to Sneathia sanguinegens . On the basis of these data, we propose the novel species Sneathia vaginalis sp. nov. with the type strain DSM 16631T (=CCUG 52977T=CCUG 52889AT) and a second strain DSM 16630 (=CCUG 52976=CCUG 52888) that were both isolated from bloodstream infections in women with puerperal fever in France. The G+C content of the DNA of the type strain is 28.4 mol% and the genome size is 1.28 Mbp. Based on the observed extremely high similarities of genotypic and phenotypic traits of the novel proposed species to those reported for ‘Sneathia amnii’, we recommend using this new name in all further publications on this taxon.

A bacterial strain THG-B283T, which has β-glucosidase activity, was isolated from soil of a ginseng field. Cells were Gram-reaction-negative, oxidase- and catalase-positive, aerobic, motile with one polar flagellum and rod-shaped. The strain was subjected to a polyphasic taxonomic study. Strain THG-B283T grew optimally at around pH 7.0, at 25–28 °C and in the absence of NaCl on R2A agar. 16S rRNA gene sequence analysis revealed that strain THG-B283T belongs to the family Sphingomonadaceae and is closely related to Sphingomonas melonis DAPP-PG 224T (98.2 %), S. aquatilis JSS7T (98.1 %), S. insulae DS-28T (97.6 %), S. mali IFO 15500T (97.1 %) and S. pruni IFO 15498T (97.0 %). Strain THG-B283T contained Q-10 as the predominant ubiquinone. The major fatty acids included summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c), C18 : 1ω7c, C14 : 0 2-OH and C16 : 0. The DNA G+C content was 72.2 mol%. The major component in the polyamine pattern was sym-homospermidine. The major polar lipids were phosphatidylglycerol, phosphatidylethanolamine, phosphatidyldimethylethanolamine, phosphatidylcholine, sphingoglycolipid, diphosphatidylglycerol, an unidentified glycolipid, unidentified aminolipids, an unidentified phospholipid and unidentified lipids. Genomic and chemotaxonomic data supported the affiliation of strain THG-B283T to the genus Sphingomonas . DNA–DNA relatedness between strain THG-B283T and its closest phylogenetic neighbours was below 23 %. On the basis of phenotypic, phylogenetic and genetic data, strain THG-B283T represents a novel species of genus Sphingomonas , for which the name Sphingomonas kyungheensis sp. nov. is proposed. The type strain is THG-B283T ( = KACC 16224T = LMG 26582T).

A novel endophytic actinomycete, designated strain NEAU-TX2-2T, was isolated from moss and characterized using a polyphasic approach. The isolate was found to have morphological characteristics typical of the genus Microbispora . The isolate formed longitudinally paired spores on the tips of short sporophores that branched from aerial hyphae. Analysis of the 16S rRNA gene sequence supported the assignment of the novel strain to the genus Microbispora , and strain NEAU-TX2-2T exhibited 99.08 and 98.62 % gene sequence similarities to Microbispora amethystogenes JCM 3021T and Microbispora rosea subsp. rosea JCM 3006T, respectively. However two tree-making algorithms supported the position that strain NEAU-TX2-2T formed a distinct clade with M. rosea subsp. rosea JCM 3006T. A low level of DNA–DNA relatedness allowed the isolate to be differentiated from M. amethystogenes JCM 3021T and M. rosea subsp. rosea JCM 3006T. Moreover, strain NEAU-TX2-2T could also be distinguished from its closest phylogenetic relatives by morphological and physiological characteristics. Therefore, it is proposed that strain NEAU-TX2-2T represents a novel species of the genus Microbispora for which the name Microbispora bryophytorum sp. nov. is proposed. The type strain is NEAU-TX2-2T ( = CGMCC 4.7138T = DSM 46710T).

A taxonomic study was performed on two isolates, designated strains MK-B5T and MK-B7, isolated from sediment of a solar saltern pond in Gomso Bay, Republic of Korea. Comparative 16S rRNA gene sequence analysis showed that strains MK-B5T and MK-B7 belong to the Gammaproteobacteria and are related most closely to Salinisphaera shabanensis JCM 11575T ( = E1L3AT) (96.3 and 96.5 % similarity, respectively), Salinisphaera dokdonensis KCCM 90064T ( = CL-ES53T) (95.6 and 95.6 %) and Salinisphaera hydrothermalis JCM 115514T ( = EPR70T) (95.1 and 95.3 %). The level of 16S rRNA gene sequence similarity between strains MK-B5T and MK-B7 was 99.8 %. The G+C contents of their genomic DNAs were 63.4 and 63.6 mol%, respectively, and the major respiratory quinone was ubiquinone-8. DNA–DNA relatedness between strains MK-B5T and MK-B7 was 98 %, indicating that the two isolates represent a single species. However, the level of DNA–DNA relatedness between the two isolates and S. shabanensis E1L3AT (26.4–30.8 %) indicates that they represent a novel species. Strains MK-B5T and MK-B7 possessed C14 : 0, C16 : 0 and C19 : 0ω8c cyclo as major fatty acids. The two isolates were Gram-stain-negative, strictly aerobic, short rod-shaped and motile. They grew at 10–40 °C (optimum, 35–37 °C), at pH 5.0–8.5 (optimum, 7.0–7.5) and with 5–25 % (w/v) NaCl (optimum, 15 % NaCl). On the basis of phenotypic and phylogenetic analyses, strains MK-B5T and MK-B7 are thus considered to represent a novel species of the genus Salinisphaera , for which the name Salinisphaera orenii sp. nov. is proposed. The type strain is MK-B5T ( = KCTC 23198T = JCM 17073T).
