Strain R2A43-10T was isolated from a greenhouse soil in Korea. Cells were Gram-negative rods, motile by means of a single flagellum. Growth occurred at 10–40 °C and at pH 5–8. Ubiquinone-8 (Q-8) was the only respiratory lipoquinone. Major fatty acids were summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) and C16 : 0. 16S rRNA gene sequence analysis revealed that strain R2A43-10T was closely related to Chitinimonas taiwanensis cfT (sequence similarity of 94.8 %), but it exhibited low sequence similarities (<92 %) to other members of the Betaproteobacteria. The G+C content of the genomic DNA of strain R2A43-10T was 65.0 mol%. The novel isolate could be differentiated from C. taiwanensis cfT by several physiological properties. On the basis of genomic and phenotypic data, it is concluded that R2A43-10T (=KACC 11467T=DSM 17726T) is the type strain of a novel species of the genus Chitinimonas, for which the name Chitinimonas koreensis sp. nov. is proposed.

A Gram-reaction-positive, rod-shaped, non-motile, non-spore-forming bacterium (strain BX5-10T) was isolated from the soil of a ginseng field on Baekdu Mountain in Jilin district, China. The taxonomic position of this bacterium was determined in an investigation based on a polyphasic approach. On the basis of 16S rRNA gene sequence analysis, strain BX5-10T was shown to belong to the family Nocardioidaceae and to be most closely related to Nocardioides plantarum NCIMB 12834T (96.5 % sequence similarity), Nocardioides dokdonensis KCTC 19309T (96.2 %) and Nocardioides fonticola NAA-13T (95.1 %). Strain BX5-10T was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in its cell-wall peptidoglycan, MK-8(H4) as the predominant menaquinone and C18 : 1ω9c, C16 : 0 and C17 : 1ω8c as its major fatty acids. The G+C content of the genomic DNA was 70.3 mol%. The novel strain could be differentiated genotypically and phenotypically from all recognized species of the genus Nocardioides. Based on the results of the phylogenetic analyses and the genotypic and phenotypic data, a novel species, Nocardioides ginsengagri sp. nov., is proposed. The type strain is BX5-10T ( = KCTC 19467T = DSM 21362T).

A yellow-coloured, aerobic, Gram-negative, rod-shaped bacterial strain, designated B-IT, was isolated from the water of a shrimp (Litopenaeus vannamei) mariculture pond in Taiwan. No species with a validly published name showed 16S rRNA gene sequence similarity of more than 96.5 % to this novel isolate. The highest sequence similarities displayed by strain B-IT (93.2–96.1 %) were to members of the genus Tenacibaculum. The phenotypic properties of this organism were consistent with its classification in the genus Tenacibaculum. The novel isolate could be distinguished from all Tenacibaculum species by several phenotypic characteristics. The major fatty acids were iso-C15 : 0 (22 %), summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH; 21.3 %), iso-C17 : 0 3-OH (12.7 %) and iso-C15 : 1 (8.7 %). The G+C content of the genomic DNA was 35.2 mol%. Hence, genotypic and phenotypic data demonstrate that strain B-IT should be classified within a novel species in the genus Tenacibaculum, for which the name Tenacibaculum litopenaei sp. nov. is proposed. The type strain is B-IT (=BCRC 17590T=LMG 23706T).

A Gram-stain-negative, rod-shaped, non-spore-forming bacterium (strain JM-1396T) producing a yellow pigment, was isolated from the healthy internal stem tissue of post-harvest cotton (Gossypium hirsutum, cultivar ‘DES-119’) grown at the Plant Breeding Unit at the E. V. Smith Research Center in Tallassee (Macon county), AL, USA. 16S rRNA gene sequence analysis of strain JM-1396T showed high sequence similarity values to the type strains of Novosphingobium mathurense, Novosphingobium panipatense (both 98.6 %) and Novosphingobium barchaimii (98.5 %); sequence similarities to all other type strains of species of the genus Novosphingobium were below 98.3 %. DNA–DNA pairing experiments of the DNA of strain JM-1396T and N. mathurense SM117T, N. panipatense SM16T and N. barchaimii DSM 25411T showed low relatedness values of 8 % (reciprocal 7 %), 24 % (reciprocal 26 %) and 19 % (reciprocal 25 %), respectively. Ubiquinone Q-10 was detected as the dominant quinone; the fatty acids C18 : 1ω7c (71.0 %) and the typical 2-hydroxy fatty acid, C14 : 0 2-OH (11.7 %), were detected as typical components. The polar lipid profile contained the diagnostic lipids diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid and phosphatidylcholine. The polyamine pattern contained the major compound spermidine and only minor amounts of other polyamines. All these data revealed that strain JM-1396T represents a novel species of the genus Novosphingobium. For this reason we propose the name Novosphingobium gossypii sp. nov. with the type strain JM-1396T ( = LMG 28605T = CCM 8569T = CIP 110884T).

A novel bacterial strain, designated THG-PC7T, was isolated from fallow farmland soil in Yongin, South Korea. Cells of strain THG-PC7T were Gram-stain-negative, dark yellow, aerobic, rod-shaped and had gliding motility. Strain THG-PC7T grew optimally at 25–35 °C, at pH 7 and in the absence of NaCl. Comparative 16S rRNA gene sequence analysis identified strain THG-PC7T as belonging to the genus Lysobacter, exhibiting highest sequence similarity with Lysobacter ximonensis KCTC 22336T (98.7 %) followed by Lysobacter niastensis KACC 11588T (95.7 %). In DNA–DNA hybridization tests, DNA relatedness between strain THG-PC7T and its closest phylogenetic neighbour L. ximonensis was below 25 %. The DNA G+C content of the novel isolate was determined to be 62.5 mol%. Flexirubin-type pigments were found to be present. The major cellular fatty acids were determined to be iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and iso-C17 : 1ω9c. The major respiratory quinone was identified as ubiquonone-8 (Q8). The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminophospolipid. On the basis of results from DNA–DNA hybridization and the polyphasic data, strain THG-PC7T represents a novel species of the genus Lysobacter, for which the name Lysobacter novalis sp. nov. is proposed. The type strain is THG-PC7T( = KACC 18276T = CCTCC AB 2014319T).

A Gram-staining-negative, strictly aerobic, motile (by gliding), non-spore-forming and rod-shaped bacterial strain, designated THG-DT86T, was isolated from soil of a ginseng field of Pocheon province in the Republic of Korea and its taxonomic position was investigated by a polyphasic approach. Growth occurred at 10–35 °C, at pH 6.5–8.5 and with 0–1.5 % (w/v) NaCl on trypticase soy agar. Flexirubin-type pigments were found to be present. On the basis of 16S rRNA gene sequence similarity, strain THG-DT86T was shown to belong to the genus Taibaiella and was related to Taibaiella smilacinae PTJT-5T (95.3 %). The G+C content of the genomic DNA was 50.1 mol%. The only isoprenoid quinone detected in strain THG-DT86T was menaquinone-7 (MK-7) and the only polyamine was homospermidine. The predominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 0, iso-C15 : 1 G and iso-C17 : 0, and the major polar lipids were phosphatidylethanolamine, an unidentified aminophosphoglycolipid and an unidentified aminophospholipid. Phenotypic data and phylogenetic inference supported the affiliation of strain THG-DT86T to the genus Taibaiella , and a number of biochemical tests differentiated strain THG-DT86T from the recognized species of the genus Taibaiella . Therefore, the novel isolate represents a novel species, for which the name Taibaiella koreensis sp. nov. is proposed, with THG-DT86T as the type strain ( = KACC 17171T = JCM 18823T).

A cholesterol side-chain-cleaving bacterial strain, AD-6T, was isolated from fresh faeces of a clouded leopard (Neofelis nebulosa) and was studied using a polyphasic taxonomic approach. 16S rRNA gene sequence analysis showed that the novel strain formed a distinct subline within the genus Gordonia, its closest neighbours being the type strains of Gordonia cholesterolivorans, Gordonia sihwensis and Gordonia hydrophobica, with sequence similarity values of 98.2, 97.8 and 97.6 %, respectively. The gyrB gene sequence of strain AD-6T exhibited similarities of 77–91 % with those of the type strains of recognized species of the genus Gordonia, being most similar to the type strains of G. sihwensis, G. hydrophobica and Gordonia hirsuta (91, 87 and 84 % similarity, respectively). The results of whole-cell fatty acid analyses and DNA–DNA relatedness data readily distinguished the new isolate from its nearest neighbours. Strain AD-6T is therefore considered to represent a novel species of the genus Gordonia, for which the name Gordonia neofelifaecis sp. nov. is proposed. The type strain is AD-6T (=NRRL B-59395T=CCTCC AB-209144T).

Strain DSM 44594T, which produces the glycopeptide antibiotic decaplanin, is a member of the genus Amycolatopsis based on 16S rRNA gene sequence analysis and chemotaxonomic properties. It is the first member of this genus that is reported to form pseudosporangia, which resemble those of members of the genus Kibdelosporangium. Phylogenetically, the novel taxon is related to Amycolatopsis orientalis, Amycolatopsis lurida, Amycolatopsis azurea, Amycolatopsis japonica and Amycolatopsis keratiniphila. Morphological, cultural and physiological properties, the production of a unique glycolipid and DNA–DNA similarity of <55 % with phylogenetically related strains reveal that strain DSM 44594T represents a novel species of the genus, for which the name Amycolatopsis decaplanina sp. nov. (type strain, FH 1845T=DSM 44594T=NRRL B-24209T) is proposed.
