A Gram-negative, obligately aerobic, rod-shaped bacterium was isolated from greenhouse soil used to cultivate lettuce. The strain, GH2-10T, was characterized on the basis of phenotypic and genotypic data. 16S rRNA gene sequence analysis revealed that the isolate belonged to the genus Devosia, with highest sequence similarity (98.5 %) to Devosia riboflavina IFO 13584T. Sequence similarities with other strains tested were below 97.0 %. Strain GH2-10T had Q-10 as the predominant ubiquinone and C18 : 1 ω7c and C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 59.5 mol%. The results of DNA–DNA hybridization experiments (47 % relatedness between D. riboflavina DSM 7230T and strain GH2-10T) and physiological and biochemical tests suggested that strain GH2-10T represents a novel species of the genus Devosia, for which the name Devosia soli sp. nov. is proposed. The type strain is GH2-10T (=KACC 11509T=DSM 17780T).

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-negative, non-spore-forming, rod-shaped, motile bacterium, strain Ko06T, was isolated from soil from a ginseng field in South Korea and was characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain Ko06T belongs to the Gammaproteobacteria, and the highest levels of sequence similarity were with Thermomonas brevis LMG 21746T (98.4 %), Thermomonas fusca LMG 21737T (97.7 %), Thermomonas haemolytica A50-7-3T (96.5 %) and Thermomonas hydrothermalis SGM-6T (95.8 %). Chemotaxonomic data revealed that strain Ko06T possesses ubiquinone Q-8 and that the predominant fatty acids are C15 : 0 iso, C11 : 0 iso and C11 : 0 iso 3-OH, all of which corroborated assignment of the strain to the genus Thermomonas. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that strain Ko06T represents a distinct species. On the basis of these data, strain Ko06T (=KCTC 12540T=NBRC 101155T) should be classified as the type strain of a novel Thermomonas species, for which the name Thermomonas koreensis sp. nov. is proposed.

Chemotaxonomic analyses revealed that strain DCY01T possessed a quinone system with Q-8 as the predominant compound, and iso-C15 : 0 (28.2 %), C16 : 0 10-methyl (13.2 %), iso-C15 : 1 F (10.8 %) and C15 : 0 (7.5 %) as major fatty acids, corroborating assignment of strain DCY01T to the genus Stenotrophomonas. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that strain DCY01T represents a species distinct from recognized Stenotrophomonas species. Based on these data, DCY01T (=KCTC 12539T=NBRC 101154T) should be classified as the type strain of a novel species of the genus Stenotrophomonas, for which the name Stenotrophomonas ginsengisoli sp. nov. is proposed.

A Gram-negative, rod-shaped, non-spore-forming bacterium, strain GH9-3T, isolated from greenhouse soil, was investigated in a polyphasic study. The novel organism grew at 10–35 °C, 0–3 % NaCl and pH 5–9. It had ubiquinone 8 (Q-8) as the predominant isoprenoid quinone and possessed C16 : 0, summed feature 3, C17 : 0 cyclo and C18 : 1 ω7c as the major fatty acids (together representing 87.4 % of the total). The DNA G+C content was 67.1 mol%. 16S rRNA gene sequence analysis of strain GH9-3T showed that it grouped within the Variovorax cluster, with highest sequence similarities to Variovorax paradoxus IAM 12373T (98.3 %) and Variovorax dokdonensis DS-43T (98.0 %). DNA–DNA hybridization values between strain GH9-3T and V. paradoxus DSM 30034T and V. dokdonensis DS-43T were 38 and 29 %, respectively. Based on phenotypic, chemotaxonomic and phylogenetic features, it is proposed that strain GH9-3T represents a novel species of the genus Variovorax with the name Variovorax soli sp. nov. The type strain is GH9-3T (=KACC 11579T=DSM 18216T).

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 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).

An aerobic, Gram-stain-negative, non-flagellated, long rod or rod-shaped bacterial strain, 5GH22-11T, was isolated from a soil sample of a greenhouse in Gongju, Republic of Korea. According to 16S rRNA gene sequence analysis, strain 5GH22-11T showed the highest sequence similarities with Niastella populi THYL-44T (97.1 %), Niastella koreensis GR20-10T (95.7 %) and Niastella yeongjuensis GR20-13T (95.6 %), and < 93 % sequence similarity with all other species with validly published names. The phylogenetic tree also showed strain 5GH22-11T formed a compact cluster with members of the genus Niastella. DNA–DNA hybridization revealed strain 5GH22-11T is a novel species, showing far less than 70 % DNA–DNA relatedness with Niastella populi THYL-44T. Strain 5GH22-11T contained iso-C15 : 0 (34.3 %), iso-C17 : 0 3-OH (24.8 %) and iso-C15 : 1 G (18.2 %) as the major fatty acids; phosphatidylethanolamine, six unknown aminolipids, two unknown lipids and one unknown phospholipid as the polar lipids; and MK-7 as the predominant isoprenoid quinone. The DNA G+C content was 41.4 mol%. Based on these phylogenetic, physiological and chemotaxonomic data, it was demonstrated that strain 5GH22-11T represents a novel species of the genus Niastella, for which the name Niastella gongjuensis sp. nov. is proposed. The type strain is 5GH22-11T ( = KACC 17399T = JCM 19941T).

Two Gram-negative, rod-shaped, non-spore-forming bacteria (CCUG 39402T and CCUG 39797), isolated from different water sources, were investigated in a polyphasic study. The two isolates shared 100 % 16S rRNA gene sequence similarity and it was shown that they belonged to the Betaproteobacteria, most closely related to Polaromonas vacuolata (97·8 %) and Polaromonas naphthalenivorans (97·8 %). A polyamine pattern with 2-hydroxyputrescine and putrescine, as well as ubiquinone Q-8, were in agreement with characteristics of Betaproteobacteria. The presence of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine, and major fatty acids C16 : 1 ω7c, C16 : 0 and C17 : 0 cyclo supported the affiliation of the two strains to the genus Polaromonas. The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of the two isolates from the two Polaromonas species with validly published names. They therefore represent a novel species, for which the name Polaromonas aquatica sp. nov. is proposed, with the type strain CCUG 39402T (=CIP 108776T).

A Gram-negative, rod-shaped, phototrophic bacterium (JA181T) was isolated from a tidal water sample. On the basis of 16S rRNA gene sequence similarity, strain JA181T was shown to belong to the class Alphaproteobacteria, most closely related to Rhodovulum sulfidophilum (97.8 % similarity to the type strain), Rhodovulum adriaticum (93 %), Rhodovulum robiginosum (93 %), Rhodovulum iodosum (94 %), Rhodovulum imhoffii (94 %), Rhodovulum strictum (95 %), Rhodovulum euryhalinum (94.6 %) and Rhodovulum marinum (94.6 %). DNA–DNA hybridization with Rdv. sulfidophilum DSM 1374T (relatedness of 39 % with strain JA181T) and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain JA181T from the eight Rhodovulum species with validly published names. Strain JA181T therefore represents a novel species, for which the name Rhodovulum visakhapatnamense sp. nov. is proposed (type strain JA181T =JCM 13531T =ATCC BAA-1274T =DSM 17937T).
