A Gram-positive, coccoid, non-endospore-forming actinobacterium (strain CCUG 35676T) was isolated from cerebrospinal fluid from a 24-year-old woman in Gothenborg, Sweden. Based on pairwise 16S rRNA gene sequence similarity studies, strain CCUG 35676T was shown to belong to the genus Dietzia and was most closely related to the type strains of Dietzia aerolata (99.3 %), Dietzia lutea (98.8 %), Dietzia schimae (98.5 %), Dietzia maris (98.5 %), Dietzia alimentaria (98.3 %) and Dietzia cercidiphylli (98.0 %). The major menaquinone was MK-8(H2). Major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, an unidentified aminophospholipid (APL1), an unidentified phospholipid (PL1) and unidentified glycolipids (GL1 and GL3). Numerous other lipids were also detected. The fatty acid profile, comprising C16 : 0, C17 : 0, C18 : 1ω9c and 10-methyl-C18 : 0 as major fatty acids, supported the affiliation of strain CCUG 35676T to the genus Dietzia. On the basis of the results of physiological and biochemical tests and DNA–DNA hybridizations, a clear phenotypic and genotypic differentiation of strain CCUG 35676T from the most closely related Dietzia species is possible. Strain CCUG 35676T represents a novel species, for which the name Dietzia aurantiaca sp. nov. is proposed, with CCUG 35676T ( = JCM 17645T) as the type strain.

A Gram-negative, rod-shaped, non-spore-forming bacterial strain, designated LMG 2337T, was isolated from the blood of a patient with endocarditis and characterized. The strain was affiliated with the alphaproteobacterial genus Brevundimonas, with Brevundimonas diminuta LMG 2089T (98.3 % 16S rRNA gene sequence similarity) and Brevundimonas terrae KSL-145T (97.5 %) as its closest relatives. This affiliation was supported by chemotaxonomic data: the G+C content was 66.3 mol %, the major polar lipids were phosphatidyl diacylglycerol, sulfoquinovosyl diacylglycerol and phosphatidyl glucopyranosyl diacylglycerol and the major fatty acids were summed feature 7 (one or more of C18 : 1 ω7c, C18 : 1 ω9t and C18 : 1 ω12t) and C16 : 0. Strain LMG 2337T displayed an unusually broad substrate spectrum. The results from DNA–DNA hybridization and physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain LMG 2337T from all of the type strains of hitherto-described Brevundimonas species. The strain therefore represents a novel species, for which the name Brevundimonas vancanneytii sp. nov. is proposed, with type strain LMG 2337T (=CCUG 1797T =ATCC 14736T).

A Gram-negative, facultatively anaerobic strain was isolated from black tea. On the basis of 16S rRNA gene sequence similarity comparisons, strain QC88-366T was grouped into the genus Pantoea, being related most closely to the type strains of Pantoea gaviniae (98.5 %) and Pantoea calida (98.3 %); sequence similarities were ≤ 97.0 % to the type strains of other species of the genus Pantoea. Multilocus sequence analysis based on partial sequences of the gyrB, rpoB, infB and atpD genes also revealed P. gaviniae and P. calida as the closest phylogenetic relatives. The fatty acid profile showed the major fatty acids of strain QC88-366T were C16 : 0, C16 : 1 and C18 : 1, the same as those of its closest related species. However, the ratio of C16 : 1, C17 : 0 cyclo, C18 : 1 and C18 : 2 differed slightly compared with those of the related neighbours. In addition, the results of physiological and biochemical tests also allowed the phenotypic differentiation of strain QC88-366T from its closest phylogenetic neighbours. The G+C content of the DNA was 57.2 mol%. Strain QC88-366T therefore represents a novel species of the genus Pantoea, for which the name Pantoea theicola sp. nov. is proposed. The type strain is QC88-366T ( = DSM 29212T = NBRC 110557T).

A Gram-negative, rod-shaped, motile, non-spore-forming bacterium, designated strain A62-14BT, was isolated from a constant-temperature, spring-fed, freshwater lake. On the basis of the complete 16S rRNA gene sequence, strain A62-14BT was shown to belong to the class Gammaproteobacteria, being most closely related to Rheinheimera sp. HTB082 (96.2 % sequence similarity), Rheinheimera baltica (95.01 %), Rheinheimera pacifica (96.35 %), Rheinheimera perlucida and Alishewanella fetalis (95.9 %). The major fatty acids (C16 : 1 ω7c, 38.56 %; C16 : 0, 19.04 %; C12 : 0 3-OH, 12.83 %; C18 : 1 ω7c, 7.70 %) and the motility of strain A62-14BT support its affiliation to the genus Rheinheimera. The salt intolerance of strain A62-14BT, together with the results of other physiological and biochemical tests, allowed the differentiation of this strain from the three species of the genus Rheinheimera with validly published names. Therefore strain A62-14BT represents a novel species of the genus Rheinheimera, for which the name Rheinheimera texasensis sp. nov. is proposed. The type strain is A62-14BT (=ATCC BAA-1235T=DSM 17496T). The description of the genus Rheinheimera is emended to reflect the halointolerance and freshwater origin of strain A62-14BT.

A Gram-negative, rod-shaped, motile bacterium was isolated from the soil of a ginseng field in Daejeon, South Korea, and characterized in order to determine its taxonomic position. Phylogenetic analysis based on 16S rRNA gene sequence analysis revealed that strain DCY34T belonged to the family Sphingomonadaceae, and the highest degree of sequence similarity was found with Sphingopyxis witflariensis W-50T (97.1 %), Sphingopyxis ginsengisoli Gsoil 250T (97.0 %), Sphingopyxis chilensis S37T (96.9 %), Sphingopyxis macrogoltabida IFO 15033T (96.8 %), Sphingopyxis alaskensis RB2256T (96.7 %) and Sphingopyxis taejonensis JSS54T (96.7 %). Chemotaxonomic data revealed that strain DCY34T possessed ubiquinone Q-10 as the predominant respiratory lipoquinone, which is common to members of the genus Sphingopyxis. The predominant fatty acids were C18 : 1 ω7c (27.5 %), summed feature 4 (C16 : 1 ω7c and/or C15 : 0 iso 2-OH; 18.6 %), C16 : 0 (15.6 %) and summed feature 8 (C19 : 1 ω6c and/or unknown 18.864; 15.4 %). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, sphingoglycolipid and an unknown polar lipid. The results of physiological and biochemical tests clearly demonstrated that strain DCY34T represented a separate species and supported its affiliation to the genus Sphingopyxis. Based on these data, the new isolate represents a novel species, for which the name Sphingopyxis panaciterrulae sp. nov. is proposed. The type strain is DCY34T (=KCTC 22112T=JCM 14844T).

A Gram-negative, rod-shaped, non-spore-forming bacteria was isolated from a nitrifying inoculum. On the basis of 16S rRNA gene sequence similarity, this strain, designated LMG 22951T, was shown to belong to the ‘Alphaproteobacteria’ and to be related to Devosia neptuniae (97·4 %) and Devosia riboflavina (97·0 %). The results of DNA–DNA hybridization, analysis of fatty acid composition, SDS-PAGE, physiological and biochemical tests allowed genotypic and phenotypic differentiation of LMG 22951T from the two recognized Devosia species. LMG 22951T therefore represents a novel species within this genus, for which the name Devosia limi is proposed. The type strain is LMG 22951T (=DSM 17137T).

A Gram-positive, rod-shaped, spore-forming bacterium, Gsoil 3088T, was isolated from soil from a ginseng field in Pocheon Province in South Korea and characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 3088T was shown to belong to the family Paenibacillaceae, being related to Brevibacillus centrosporus (96.6 %), Brevibacillus borstelensis (96.3 %), Brevibacillus parabrevis (96.1 %), Brevibacillus formosus (96.1 %), Brevibacillus brevis (96.1 %) and Brevibacillus laterosporus (96.0 %). The phylogenetic distances from other validly described species within the genus Brevibacillus were greater than 4.0 % (i.e. there was less than 96.0 % similarity). The G+C content of the genomic DNA was 52.1 mol%. Phenotypic and chemotaxonomic data (major menaquinone, MK-7; fatty acid profile, iso-C15 : 0, iso-C14 : 0 and anteiso-C15 : 0) supported the affiliation of strain Gsoil 3088T to the genus Brevibacillus. The results of physiological and biochemical tests allowed strain Gsoil 3088T to be distinguished genotypically and phenotypically from Brevibacillus species with validly published names. Strain Gsoil 3088T, therefore, represents a novel species of the genus Brevibacillus, for which the name Brevibacillus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 3088T (=KCTC 13938T=LMG 23403T).

A bacterial strain (designated KMY03T) that possesses β-glucosidase activity was isolated from soil from a ginseng field in South Korea and was characterized in order to determine its taxonomic position. The bacterium was found to comprise Gram-negative, rod-shaped, motile cells with unipolar polytrichous flagella. On the basis of 16S rRNA gene sequence similarity, strain KMY03T was shown to belong to the family Burkholderiaceae of the Betaproteobacteria, being most closely related to Burkholderia caledonica LMG 19076T (97.8 %), Burkholderia terricola LMG 20594T (97.5 %), Burkholderia xenovorans LMG 21463T (97.4 %) and Burkholderia phytofirmans LMG 22146T (97.3 %). Chemotaxonomic data (major ubiquinone, Q-8; major fatty acids, C17 : 0 cyclo, C16 : 0, C19 : 0 cyclo ω8c and summed feature 2) supported the affiliation of the novel strain with the genus Burkholderia. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed the strain to be differentiated genotypically and phenotypically from Burkholderia species with validly published names. On the basis of these data, strain KMY03T represents a novel species of the genus Burkholderia, for which the name Burkholderia ginsengisoli sp. nov. is proposed. The type strain is KMY03T (=KCTC 12389T=NBRC 100965T).

A Gram-negative, rod-shaped, non-spore-forming bacterium (strain NS11T) was isolated from a lichen-colonized rock surface. On the basis of 16S rRNA gene sequence similarity, strain NS11T was shown to belong to the Betaproteobacteria, and was most closely related to Herminiimonas arsenicoxydans ULPAs1T (98.8 %), Herminiimonas aquatilis CCUG 36956T (98.0 %) and Herminiimonas fonticola S-94T (98.0 %). Major whole-cell fatty acids were C16 : 0, C17 : 0 cyclo and C16 : 1 ω7c. Strain NS11T also contained high proportions of C10 : 0 3-OH and C18 : 1 ω7c. This pattern is typical for members of the genus Herminiimonas. The results of DNA–DNA hybridization experiments and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain NS11T from the three recognized Herminiimonas species. It is therefore concluded that strain NS11T represents a novel species of the genus Herminiimonas, for which the name Herminiimonas saxobsidens sp. nov. is proposed. The type strain is NS11T (=DSM 18748T=CCM 7436T).

A coral-red-pigmented actinobacterium, strain K30-10T, was isolated from a soil sample from a cold desert of the Indian Himalayas. Chemical and phenotypic properties of strain K30-10T were consistent with its classification in the genus Dietzia. It showed 97.9 % 16S rRNA gene sequence similarity to Dietzia maris MTCC 7011T; similarities to the type strains of three other species of the genus, Dietzia natronolimnaea, Dietzia psychralcaliphila and Dietzia cinnamea, were 94.4–96.0 %. The DNA–DNA relatedness between K30-10T and the closely related strain D. maris MTCC 7011T was 59.2 %. The DNA G+C content of strain K30-10T was 67.0 mol%. Based on physiological and biochemical tests and genotypic differences between strain K30-10T and its closest phylogenetic relatives, it is proposed that this strain represents a novel species, Dietzia kunjamensis sp. nov.; the type strain is K30-10T (=MTCC 7007T=DSM 44907T=JCM 13325T).

Sixteen Gram-negative, rod-shaped, non-spore-forming isolates were obtained from a nitrifying inoculum. Analysis of repetitive sequence-based PCR and SDS-PAGE banding patterns, 16S rRNA gene sequence analysis and DNA–DNA hybridizations showed that the isolates belonged to various groups within the genus Pseudomonas. One group of isolates could be assigned to Pseudomonas migulae and a second to Pseudomonas veronii. Two groups could be differentiated genotypically from each other and from all other currently known Pseudomonas species. Analysis of the fatty acid composition and physiological and biochemical tests allowed differentiation of these groups from their closest phylogenetic neighbours and they therefore represent two novel species within the genus Pseudomonas, for which the names Pseudomonas peli sp. nov. and Pseudomonas borbori sp. nov. are proposed, with strains LMG 23201T (=DSM 17833T=R-20805T) and LMG 23199T (=DSM 17834T=R-20821T), respectively, as the type strains.
