Strain UST040317-058T, comprising non-pigmented, rod-shaped, facultatively anaerobic, Gram-negative cells that are motile by means of single polar flagella, was isolated from the surface of a marine sponge (Ircinia dendroides) collected from the Mediterranean Sea. Comparative 16S rRNA gene sequence-based phylogenetic analysis placed the strain in a separate cluster with the recognized bacterium Shewanella algae IAM 14159T, with which it showed a sequence similarity of 95.0 %. The sequence similarity between strain UST040317-058T and its other (six) closest relatives ranged from 91.6 to 93.8 %. Strain UST040317-058T showed oxidase, catalase and gelatinase activities. The typical respiratory quinones for shewanellas, menaquinone MK-7 and ubiquinones Q-7 and Q-8, were also detected. The predominant fatty acids in strain UST040317-058T were i15 : 0, 16 : 0, 17 : 1ω8c and summed feature 3 (comprising i15 : 0 2-OH and/or 16 : 1ω7c), altogether representing 56.9 % of the total. The DNA G+C content was 39.9 mol%. The strain could be differentiated from other Shewanella species by its inability to reduce nitrate or produce H2S and by 10–22 additional phenotypic characteristics. On the basis of the phylogenetic and phenotypic data presented in this study, strain UST040317-058T represents a novel species in the genus Shewanella, for which the name Shewanella irciniae sp. nov. is proposed. The type strain is UST040317-058T (=JCM 13528T=NRRL B-41466T).

The taxonomic position of an actinobacterium strain, C296001T, isolated from a soil sample collected in Sarawak, Malaysia, was established using a polyphasic approach. Phylogenetically, strain C296001T was closely associated with the genus Luteipulveratus and formed a distinct monophyletic clade with the only described species, Luteipulveratus mongoliensis NBRC 105296T. The 16S rRNA gene sequence similarity between strain C296001T and L. mongoliensis was 98.7 %. DNA–DNA hybridization results showed that the relatedness of strain C296001T to L. mongoliensis was only 21.5 %. The DNA G+C content of strain C296001T was 71.7 mol%. Using a PacBio RS II system, whole genome sequences for strains C296001T and NBRC 105296T were obtained. The genome sizes of 4.5 Mbp and 5.4 Mbp determined were similar to those of other members of the family Dermacoccaceae. The cell-wall peptidoglycan contained lysine, alanine, aspartic acid, glutamic acid and serine, representing the peptidoglycan type A4α l-Lys-l-Ser-d-Asp. The major menaquinones were MK-8(H4), MK-8 and MK-8(H2). Phosphatidylglycerol, phosphatidylinositol, diphosphatidylglycerol and phosphoglycolipid were the polar lipids, while the whole-cell sugars were glucose, fucose and lesser amounts of ribose and galactose. The major fatty acids were iso-C16 : 0, anteiso-C17 : 0, iso-C16 : 1 H, anteiso-C17 : 1ω9c, iso-C18 : 0 and 10-methyl C17 : 0. Chemotaxonomic analyses showed that C296001T had typical characteristics of members of the genus Luteipulveratus, with the main differences occurring in phenotypic characteristics. On the basis of the phenotypic and chemotaxonomic evidence, it is proposed that strain C296001T be classified as a representative of a novel species in the genus Luteipulveratus, for which the name Luteipulveratus halotolerans sp. nov. is recommended. The type strain is C296001T ( = ATCC TSD-4T = JCM 30660T).

The taxonomic position of the coral pathogen strain CBMAI 722T was determined on the basis of molecular and phenotypic data. We clearly show that the novel isolate CBMAI 722T is a member of the family Colwelliaceae, with Thalassomonas ganghwensis as the nearest neighbour (95 % 16S rRNA gene sequence similarity). CBMAI 722T can be differentiated from its nearest neighbour on the basis of phenotypic and chemotaxonomic features, including the utilization of cellobiose and l-arginine, the production of alginase and amylase, but not oxidase, and the presence of the fatty acids 12 : 0 3-OH and 14 : 0, but not 10 : 0 or 15 : 0. The DNA G+C content of CBMAI 722T is 39·3 mol%. We conclude that this strain represents a novel species for which we propose the name Thalassomonas loyana sp. nov., with the type strain CBMAI 722T (=LMG 22536T). This is the first report of the involvement of a member of the family Colwelliaceae in coral white plague-like disease.

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-negative, rod-shaped, Flavobacterium-like bacterial strain, DS-20T, was isolated from soil from the island of Dokdo, Korea, and subjected to a polyphasic taxonomic study. Strain DS-20T grew optimally at pH 6.5–7.0 and 25 °C. It contained MK-6 as the predominant menaquinone and iso-C15 : 0, iso-C17 : 0 3-OH and iso-C17 : 1 ω9c as the major fatty acids. The DNA G+C content was 38.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-20T belonged to the genus Flavobacterium. Levels of 16S rRNA gene sequence similarity between strain DS-20T and the type strains of recognized Flavobacterium species were below 94.9 %. Strain DS-20T differed from phylogenetically related Flavobacterium species in several phenotypic characteristics. On the basis of its phenotypic and phylogenetic distinctiveness, strain DS-20T was classified in the genus Flavobacterium as representing a novel species, for which the name Flavobacterium terrigena sp. nov. is proposed. The type strain is DS-20T (=KCTC 12761T=DSM 17934T).

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

A Gram-negative, strictly aerobic, rod-shaped, non-motile, non-spore-forming bacterial strain, designated TR6-04T, was isolated from compost and characterized taxonomically by using a polyphasic approach. The organism grew optimally at 30 °C and at pH 6.5–7.0. The isolate was positive for catalase and oxidase tests but negative for gelatinase, indole and H2S production. Comparative 16S rRNA gene sequence analysis showed that strain TR6-04T fell within the radiation of the cluster comprising Sphingobacterium species and clustered with Sphingobacterium mizutaii ATCC 33299T (96.7 % sequence similarity); the similarity to sequences of other species within the family Sphingobacteriaceae was less than 92.0 %. The G+C content of the genomic DNA was 38.7 mol%. The predominant respiratory quinone was MK-7. The major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c). These chemotaxonomic data supported the affiliation of strain TR6-04T to the genus Sphingobacterium. However, on the basis of its phenotypic properties and phylogenetic distinctiveness, strain TR6-04T (=KCTC 12579T=LMG 23402T=CCUG 52468T) should be classified as the type strain of a novel species, for which the name Sphingobacterium daejeonense sp. nov. is proposed.

A Gram-negative, rod-shaped, non-spore-forming bacterium (designated strain Kw05T) was isolated from granules used in the wastewater treatment plant of a beer-brewing factory in Kwang-Ju, Republic of Korea. On the basis of 16S rRNA gene sequence similarity, strain Kw05T was shown to belong to the family Flavobacteriaceae, and was most closely related to Flavobacterium limicola (96·6 %), Flavobacterium hibernum (96·3 %), Flavobacterium hydatis (96·1 %) and Flavobacterium xinjiangense (96·1 %). The G+C content of the genomic DNA of strain Kw05T was 36·2 mol%, within the range of 32–37 mol% for the genus Flavobacterium. Chemotaxonomic data (major menaquinone MK-6; major fatty acids iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 0 3-OH and iso-C17 : 1 ω9c) supported the classification of strain Kw05T within the genus Flavobacterium. Kw05T therefore represents a novel species, for which the name Flavobacterium granuli sp. nov. is proposed. The type strain is Kw05T (=KCTC 12201T=IAM 15099T).

Gram-positive, spore-forming rods were isolated from blood cultures of three different patients. Based on phylogenetic analyses, these strains were placed within the Paenibacillus cluster and specific phenotypic characteristics for each strain were described. Levels of 16S rRNA gene sequence similarity between existing Paenibacillus species and the three novel strains 2301065T, 2301032T and 2301083T were 87·6–94·4, 88·5–95·4 and 87·5–96·0 %, respectively, and anteiso-branched C15 : 0 was the major fatty acid. On the basis of phenotypic data and phylogenetic inference, it is proposed that these strains should be designated Paenibacillus massiliensis sp. nov., Paenibacillus sanguinis sp. nov. and Paenibacillus timonensis sp. nov. The type strains are respectively strain 2301065T (=CIP 107939T=CCUG 48215T), strain 2301083T (=CIP 107938T=CCUG 48214T) and strain 2301032T (=CIP 108005T=CCUG 48216T).

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).
