An orange-coloured, rod-shaped, non-motile, Gram-reaction-negative, strictly aerobic bacterial strain, designated JC2680T, was isolated from a seawater sample of Jeju Island, Korea. The isolate required sea salts for growth. Flexirubin-type pigments were absent. 16S rRNA gene sequence analysis indicated that the test strain belonged to the genus Aquimarina within the family Flavobacteriaceae, but shared relatively low levels of similarity (93.6–95.9 %) with the type strains of recognized Aquimarina species. The predominant cellular fatty acids [iso-C17 : 0 3-OH, iso-C15 : 0 and summed feature 9 (comprising 10-methyl C16 : 0 and/or iso-C17 : 1ω9c) and DNA G+C content (35 mol%) were consistent with the assignment of strain JC2680T to the genus Aquimarina. However, a number of phenotypic characteristics, namely inability to grow under microaerophilic conditions, differences in enzyme reactions, and absence of flexirubin-type pigments and gliding motility, clearly distinguished strain JC2680T from recognized species of the genus Aquimarina. The data presented thus indicate that strain JC2680T represents a novel species of the genus Aquimarina, for which the name Aquimarina addita sp. nov. is proposed. The type strain is JC2680T ( = KACC 14156T  = JCM 17106T).

A novel bacterial strain, S1-9T, was isolated from a lead–zinc tailing in Nanjing, Jiangsu Province, China. Cells of strain S1-9T were Gram-stain-negative, ellipsoidal endospore-forming, aerobic rods and motile by means of peritrichous flagella. On the basis of 16S rRNA gene sequence analysis, strain S1-9T was shown to belong to the genus Paenibacillus and the closest phylogenetic relatives were Paenibacillus glucanolyticus DSM 5162T (96.8 % similarity), Paenibacillus lautus NRRL NRS-666T (96.5 %) and Paenibacillus lactis MB 1871T (95.4 %). The predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15:0 and iso-C16:0. The polar lipid profile contained phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, two unknown phospholipids and two unknown lipids. The total DNA G+C content of strain S1-9T was 49.9 mol%. Based on the low levels of DNA–DNA relatedness (ranging from 21.8 to 48.4 %) to the type strains of the above species of the genus Paenibacillus and unique phenotypic characteristics, strain S1-9T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus qingshengii sp. nov. is proposed. The type strain is S1-9T ( = CCTCC AB 2014290T = JCM 30613T).

A strictly aerobic, orange-pigmented and Gram-staining-negative bacterium, designated K17-16T, was isolated from seawater of Gangjin Bay, Korea. Comparative 16S rRNA gene sequence analysis revealed that strain K17-16T was a member of the genus Polaribacter in the family Flavobacteriaceae and showed 94.0–95.6 % sequence similarity with the type strains of recognized species of the genus Polaribacter. The G+C content of the genomic DNA was 34.6 mol% and the major respiratory lipoquinone was MK-6. The major polar lipids detected were phosphatidylethanolamine, three unidentified amino-group-containing lipids and an unidentified aminophospholipid. The predominant cellular fatty acids were iso-C15 : 0 (15.4 %), C15 : 0 (12.4 %), summed feature 3 (comprising iso-C15 : 0 2-OH and/or C16 : 1ω7c; 10.6 %), C15 : 1ω6c (9.8 %) and iso-C15 : 0 3-OH (8.6 %). On the basis of phenotypic and genotypic data, strain K17-16T represents a novel species in the genus Polaribacter, for which the name Polaribacter gangjinensis sp. nov. is proposed. The type strain is K17-16T ( = KCTC 22729T = JCM 16152T).

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 bacterium (designated strain UST030701-295T) with fast gliding motility was isolated from the surface of the sponge Lissodendoryx isodictyalis in the Bahamas. Colonies of UST030701-295T were yellow in colour, 2–4 mm in diameter, convex with a smooth surface and entire margins. UST030701-295T was heterotrophic, strictly aerobic and required NaCl for growth (1·0–4·0 %). Growth was observed at pH 6·0–10·0 and at 12–44 °C. Phylogenetic analysis of the 16S rRNA gene sequence placed UST030701-295T within the genus Winogradskyella of the family Flavobacteriaceae, sharing 94·7–95·8 % similarity with the three recognized members of the genus. The G+C content of the DNA was 32·8 mol% and the predominant fatty acids were iso-C15 : 1, iso-C15 : 0, iso-C15 : 0 2-OH, iso-C15 : 0 3-OH, iso-C16 : 0 3-OH, C16 : 1 ω7 and iso-C17 : 0 3-OH (together representing 75·4 % of the total); these data supported the affiliation of UST030701-295T to the genus Winogradskyella. UST030701-295T differed from the three recognized species of Winogradskyella in 7–17 traits. Molecular evidence together with phenotypic characteristics suggests that UST030701-295T represents a novel species within the genus Winogradskyella, for which the name Winogradskyella poriferorum sp. nov. is proposed. The type strain is UST030701-295T (=NRRL B-41101T=JCM 12885T).

A Gram-positive, endospore-forming, alkalitolerant bacterial strain, designated MLB2T, was isolated from soil from Leh, India, and was subjected to a polyphasic taxonomic study. The strain exhibited phenotypic properties that included chemotaxonomic characteristics consistent with its classification in the genus Bacillus. Growth was observed at pH 7.0–11.0, but not at pH 6.0. The DNA G+C content was 41.4 mol%. The highest level of 16S rRNA gene sequence similarity was with Bacillus oshimensis JCM 12663T (98.8 %). However, DNA–DNA hybridization experiments indicated low levels of genomic relatedness with the type strains of B. oshimensis (62 %), Bacillus patagoniensis (55 %), Bacillus clausii (51 %) and Bacillus gibsonii (34 %), the species with which strain MLB2T formed a coherent cluster (based on the results of the phylogenetic analysis). On the basis of the phenotypic characteristics and genotypic distinctiveness of strain MLB2T, it should be classified within a novel species of Bacillus, for which the name Bacillus lehensis sp. nov. is proposed. The type strain is MLB2T (=MTCC 7633T=JCM 13820T).
