A novel Gram-stain-negative rod-shaped gliding bacterial strain, designated 35/09T, was isolated from diseased European sea bass (Dicentrarchus labrax L.) in Spain. Colonies were pale-yellow-pigmented with uneven edges and did not adhere to the agar. The DNA G+C content of the isolate was 31.3 mol%. 16S rRNA gene sequence analysis indicated affiliation to the genus Tenacibaculum (family Flavobacteriaceae, phylum ‘Bacteroidetes’). Sequence similarities between the isolate and type strains of other members of the genus were 93.1–97.3 %. The major fatty acids (>5 % of the total fatty acids) were iso-C15 : 0 (24.8 %), iso-C15 : 0 3-OH (18.0 %), anteiso-C15 : 0 (8.1 %), C15 : 1ω6c (6.9 %) and iso-C15 : 1 (6.2 %). Genotypic and phenotypic data indicate that strain 35/09T should be classified as a representative of a novel species in the genus Tenacibaculum, for which the name Tenacibaculum dicentrarchi sp. nov. is proposed; the type strain is 35/09T ( = CECT 7612T = NCIMB 14598T).

The taxonomic position of two soil actinomycetes, strains A2012T and A2019T, isolated from Turkish soils, was determined using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that the strains belonged to the family Nocardiaceae . Strains A2012T and A2019T were most closely related to Nocardia caishijiensis DSM 44831T (98.9 %) and Nocardia mexicana CIP 108295T (98.6 %), respectively; similarity to other type strains of the genus Nocardia ranged from 96.9 to 97.9 %. However, DNA–DNA relatedness and phenotypic data demonstrated that strains A2012T and A2019T could be clearly distinguished from members of the most closely related Nocardia species. It is evident from the genotypic and phenotypic data that the two isolates represent two novel species of the genus Nocardia . It is proposed, therefore, that strains A2012T and A2019T be classified in the genus Nocardia as representatives of Nocardia goodfellowii sp. nov. (type strain A2012T = DSM 45516T = NRRL B-24833T = KCTC 19986T) and Nocardia thraciensis sp. nov. (type strain A2019T = DSM 45517T = NRRL B-24834T = KCTC 19985T), respectively.

A Gram-stain-negative, yellow, non-spore-forming, strictly aerobic bacterium, designated C3T, was isolated from a cyanobacterial culture pond. Cells were halophilic, rod-shaped and able to move by gliding. Growth of strain C3T was observed at 15–30 °C (optimum 25 °C), pH 6.0–9.0 (optimum pH 7.5), and in the presence of 1–7 % (w/v) NaCl (optimum 2–3 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain C3T formed a distinct lineage within the family Flavobacteriaceae and exhibited the highest similarity (95.21 %) to the type strains of Maribacter dokdonensis, Maribacter arcticus, Maribacter orientalis and Maribacter stanieri, and ‘Maribacter caenipelagi’ HD-44. The only isoprenoid quinone present within strain C3T was menaquinone 6 (MK-6). The G+C content of genomic DNA was 41.5 mol%. The major polar lipids were phosphatidylethanolamine and three unidentified lipids. The predominant cellular fatty acids (>5 % of the total fatty acids) were iso-C15 : 1 G, iso-C15 : 0, iso-C15 : 0 3-OH, iso-C17 : 0 3-OH, and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). On the basis of the phenotypic, chemotaxonomic and phylogenetic characteristics, strain C3T represents a novel species of the genus Maribacter, for which the name Maribacter flavus sp. nov. is proposed. The type strain is C3T ( = KCTC 42508T = CGMCC 1.15112T).

A novel aerobic, Gram-negative, motile, rod-shaped bacterial strain designated 5516S-2T was isolated from an air sample taken in Suwon, Republic of Korea. Colonies were yellow-pigmented and circular with entire margins. 16S rRNA gene sequence analysis showed that strain 5516S-2T was closely related to Xylophilus ampelinus DSM 7250T (97.6 % sequence similarity), Variovorax soli KACC 11579T (97.5 %) and Xenophilus azovorans DSM 13620T (97.1 %). However, the phylogenetic tree indicated that strain 5516S-2T formed a separate clade from Xenophilus azovorans. Strain 5516S-2T displayed 42, 31 and 30 % DNA–DNA relatedness to the type strains of Xenophilus azovorans, Xylophilus ampelinus and V. soli, respectively. The major fatty acids (>10 % of total fatty acids) were C16 : 0 (33.3 %), C17 : 0 cyclo (18.8 %), C18 : 1 ω7c (17.5 %) and summed feature 3 (comprising C16 : 1 ω7c and/or iso-C15 : 0 2-OH; 13.0 %). The DNA G+C content was 69 mol%. The major quinone was ubiquinone Q-8. The predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and two unknown aminophospholipids. Genotypic and phenotypic characteristics clearly distinguished strain 5516S-2T from closely related species and indicated that it represents a novel species within the genus Xenophilus, for which the name Xenophilus aerolatus sp. nov. is proposed. The type strain is 5516S-2T (=KACC 12602T=DSM 19424T).

A Gram-negative, catalase-negative, oxidase-positive, rod-shaped bacterium, strain DQHS21T, was isolated from sediment of a seawater pond used for sea cucumber culture at Jimo in Qingdao province on the east coast of China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DQHS21T belonged to the genus Cohaesibacter, sharing the highest sequence similarity (96.1 %) with Cohaesibacter gelatinilyticus CL-GR15T, while the similarity to other strains was below 93.0 %. The cellular fatty acids consisted mainly of C18 : 1ω7c (60.7 %), C18 : 0 (17.8 %), C16 : 0 (8.5 %) and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH; 6.0 %), which together accounted for 93 % of the total fatty acids. Ubiquinone 10 was the major quinone. The G+C content of the chromosomal DNA of strain DQHS21T was 55.2 mol%. The combined genotypic and phenotypic data showed that strain DQHS21T represents a novel species of the genus Cohaesibacter, for which the name Cohaesibacter marisflavi sp. nov. is proposed, with the type strain DQHS21T ( = CGMCC 1.9157T  = NCCB 100300T).

‘Bacillus macroides’ ATCC 12905T ( = DSM 54T = LMG 18474T), isolated in 1947 from cow dung, was not included in the Approved Lists of Bacterial Names and so it lost standing in bacteriological nomenclature. Reinvestigation of the strain, including DNA–DNA relatedness experiments, revealed that ‘Bacillus macroides’ is genomically distinct from its closest relatives Lysinibacillus xylanilyticus , Lysinibacillus boronitolerans and Lysinibacillus fusiformis (as determined by 16S rRNA gene sequence analysis, with pairwise similarity values of 99.2, 98.8 and 98.5 %, respectively, with the type strains of these species). Further analysis showed that ‘Bacillus macroides’ shares the A4α l-Lys–d-Asp peptidoglycan type with other members of the genus Lysinibacillus and can thus be attributed to this genus. These results, combined with additional phenotypic data, justify the description of strain LMG 18474T ( = DSM 54T = ATCC 12905T) as Lysinibacillus macroides sp. nov., nom. rev.

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 soil isolate, strain CC-AB07T, was characterized using a polyphasic approach. This organism had chemotaxonomic and morphological properties consistent with its classification in the genus Gordonia. 16S rRNA gene sequence analysis showed that the novel strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus Gordonia, its closest neighbours being the type strains of Gordonia alkanivorans, Gordonia amicalis, Gordonia bronchialis, Gordonia desulfuricans, Gordonia polyisoprenivorans and Gordonia rhizosphera. The novel isolate was distinguished from all of these type strains using a range of phenotypic properties and by gyrB gene sequence analysis. It was evident from the genotypic and phenotypic data that strain CC-AB07T should be classified as representing a novel species in the genus Gordonia, for which the name Gordonia soli sp. nov. is proposed. The type strain is CC-AB07T (=BCRC 16810T=DSM 44995T).
