A Gram-reaction-negative, yellow-pigmented, gliding, rod-shaped, aerobic bacterium (RA5-111T) was isolated from foreshore soil. The taxonomic status of the novel isolate was determined using a polyphasic approach. On the basis of 16S rRNA gene sequence similarities, strain RA5-111T could be assigned to the genus Gramella, with sequence similarities of 97.7, 97.3 and 96.2 % to the type strains of Gramella echinicola, Gramella portivictoriae and Gramella marina, respectively. Chemotaxonomic and phenotypic characteristics also supported the affiliation of strain RA5-111T with the genus Gramella. The genomic DNA G+C content was 39.1 mol%. The isolate contained MK-6 as the predominant menaquinone, iso-C15 : 0, iso-C17 : 0 3-OH and a summed feature (iso-C15 : 0 2-OH and/or C16 : 1ω7c) as major fatty acids, and phosphatidylethanolamine and unknown phospholipids as the polar lipids. DNA–DNA relatedness, phenotypic, genotypic and chemotaxonomic data clearly indicate that the isolate represents a novel species of the genus Gramella, for which the name Gramella gaetbulicola sp. nov. is proposed. The type strain is RA5-111T ( = KCTC 23022T  = JCM 16528T  = NBRC 106272T).

Strain BZ30T was isolated from hydrocarbon-contaminated soil. The Gram-negative, aerobic bacterium was psychrophilic and able to grow at temperatures ranging from 1 to 30 °C. The predominant cellular fatty acids of strain BZ30T were summed feature 3 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH) (37.4 %), C18 : 1 ω7c (19.6 %), C16 : 0 (8.2 %), C14 : 0 2-OH (8.0 %) and C16 : 0 2-OH (5.0 %). The predominant ubiquinone was Q-10. Major polar lipids were sphingoglycolipids, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine. Spermidine was the major polyamine. The genomic DNA G+C content was 64.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain BZ30T belonged to the family Sphingomonadaceae of the α-4 group of the phylum Proteobacteria, and was related to the members of the genus Sphingopyxis, sharing the highest sequence similarities with the type strains of Sphingopyxis chilensis (98.3 %), S. witflariensis (98.2 %), S. taejonensis (97.4 %) and S. ginsengisoli (97.2 %). On the basis of the phenotypic characteristics, phylogenetic analysis and DNA–DNA relatedness data, strain BZ30T represents a novel species of the genus Sphingopyxis, for which the name Sphingopyxis bauzanensis is proposed. The type strain is BZ30T (=DSM 22271T =CGMCC 1.8959T =CIP 110136T).

A polyphasic study was undertaken to establish the taxonomic status of a Gram-positive, aerobic actinomycete, strain HPA177T, isolated from a marine sponge, Hymeniacidon perleve. The organism formed branching, non-fragmenting vegetative hyphae and produced black pigment. Chemotaxonomic characteristics were consistent with its assignment to the genus Actinoalloteichus. Analysis of the 16S rRNA gene sequence showed that strain HPA177T formed a robust clade with type strains of the genus Actinoalloteichus, but was distinct from them. A number of phenotypic characteristics also readily distinguished strain HPA177T from species of the genus Actinoalloteichus with validly published names. On the basis of the above data, it is proposed that strain HPA177T represents a novel species, Actinoalloteichus hymeniacidonis sp. nov. The type strain of Actinoalloteichus hymeniacidonis is HPA177T (=CGMCC 4.2500T=JCM 13436T).

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).

Three Gram-negative, anaerobic, rod-shaped bacteria (strains CB40, CB41 and CB42T) were isolated from human faeces. Based on phylogenetic analysis and specific phenotypic characteristics, these strains were included in the genus Bacteroides, and 16S rRNA gene sequence analysis indicated that these strains represented a novel species. The strains were most closely related to the type strains of Bacteroides barnesiae and Bacteroides salanitronis, with sequence similarities of 93.4 and 89.8 %, respectively. The G+C content of strain CB42T is 44.7 mol%. Major fatty acids were anteiso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH and C18 : 1 ω9c. On the basis of the data presented, a novel Bacteroides species, Bacteroides coprophilus sp. nov., is proposed, with CB42T (=JCM 13818T=DSM 18228T) as the type strain.

A Gram-negative, aerobic bacterium, designated strain FR1439T, was isolated from the soil of Dokdo in the Republic of Korea. The cells of strain FR1439T were catalase- and oxidase-positive, motile and rod-shaped. Phylogenetic analysis of the 16S rRNA gene sequence revealed that it represents a distinct line of descent within the genus Pseudomonas. The levels of DNA–DNA relatedness between strain FR1439T and type strains of phylogenetically related species, namely Pseudomonas flavescens, Pseudomonas mendocina, Pseudomonas pseudoalcaligenes and Pseudomonas straminea, ranged from 28 to 37 %. Several phenotypic characteristics, together with the cellular fatty acid composition, can be used to differentiate strain FR1439T from related pseudomonads. On the basis of the polyphasic taxonomic evidence presented in this study, strain FR1439T represents a novel species, for which the name Pseudomonas segetis sp. nov. is proposed. The type strain is FR1439T (=IMSNU 14101T=CIP 108523T=KCTC 12331T).

An actinomycete, strain 4776T, was isolated from soil collected from Emei Mountain in Sichuan Province, China. The taxonomic status of this strain was established using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of streptomycetes. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that the novel isolate belongs to the genus Streptomyces and consistently falls into a clade together with Streptomyces prasinopilosus DSM 40098T, Streptomyces prasinus JCM 4603T, Streptomyces bambergiensis DSM 40590T, Streptomyces hirsutus DSM 40095T and Streptomyces cyanoalbus DSM 40198T. However, DNA–DNA relatedness and phenotypic data distinguished strain 4776T from these phylogenetically related type strains. It is therefore concluded that strain 4776T (=CGMCC 4.3504T=DSM 41884T) represents a novel species of the genus Streptomyces, for which the name Streptomyces emeienseis sp. nov. is proposed.

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, non-motile bacterium, designated MJ17T, was isolated from sludge at the Daejeon sewage disposal plant in South Korea. Comparative 16S rRNA gene sequence analysis showed that strain MJ17T belonged to the genus Paracoccus in the family Rhodobacteraceae of the class Alphaproteobacteria. 16S rRNA gene sequence similarities between strain MJ17T and type strains of species of the genus Paracoccus were 94.1–97.4 %. The highest similarities were between strain MJ17T and Paracoccus homiensis DD-R11T, Paracoccus zeaxanthinifaciens ATCC 21588T and Paracoccus alcaliphilus JCM 7364T (97.4, 97.2 and 96.3 %, respectively). Strain MJ17T exhibited <22 % DNA–DNA relatedness with P. homiensis KACC 11518T and P. zeaxanthinifaciens JCM 21774T. The G+C content of the genomic DNA was 58.7 mol%. Strain MJ17T contained ubiquinone Q-10. The major fatty acids were C18 : 0 (11.3 %), C16 : 0 (10.2 %) and summed feature 7 (containing one or more of C18 : 1ω7c, C18 : 1ω9c and C18 : 1ω12t; 54.3 %). Poly-β-hydroxybutyrate granules are formed. On the basis of phenotypic and genotypic properties and phylogenetic distinctiveness, strain MJ17T should be classified in a novel species of the genus Paracoccus, for which the name Paracoccus caeni sp. nov. is proposed. The type strain is MJ17T ( = KCTC 22480T  = JCM 16385T  = KEMB 9004-001T).

Three Gram-positive-staining strains isolated from fermented stinky tofu brine were rod-shaped, non-motile, asporogenous, facultatively anaerobic, heterofermentative and did not exhibit catalase activity. Comparative analyses of 16S rRNA, rpoA and pheS gene sequences demonstrated that the novel strains were members of the genus Lactobacillus. On the basis of 16S rRNA gene sequence similarity, the type strains of Lactobacillus collinoides (98.6 %), Lactobacillus paracollinoides (98.6 %) and Lactobacillus similis (99.6 %) were the closest neighbours. However, DNA–DNA reassociation values with these strains were less than 10 %. The phenotypic and genotypic features demonstrated that these isolates represent a novel species of the genus Lactobacillus, for which the name Lactobacillus odoratitofui sp. nov. is proposed. The type strain is YIT 11304T (=JCM 15043T =BCRC 17810T =DSM 19909T).
