An actinomycete strain, NAR01T, was isolated from root nodules of a Coriaria plant. The 16S rRNA gene sequence of strain NAR01T showed most similarity to the type strains of Micromonospora endolithica (98.94 %) and Micromonospora chersina (98.4 %). The chemotaxonomic results obtained confirmed the taxonomic position of the isolate within the genus Micromonospora, and revealed differences at the species level. Physiological and biochemical tests showed that strain NAR01T could be clearly distinguished from its closest phylogenetic neighbours, while DNA–DNA hybridization results indicated that the isolate represents a novel species. On the basis of these results, strain NAR01T (=DSM 44875T=LMG 23557T) is proposed as the type strain of the novel species Micromonospora coriariae sp. nov.

An actinomycete strain was recovered from a pond where radon is known to be dissolved. A polyphasic study was undertaken to identify the new isolate. The 16S rRNA gene sequence of strain WA201T showed closest similarity to the type strains of Micromonospora carbonacea (98·5 %) and Micromonospora matsumotoense (98·1 %). The chemotaxonomic results confirmed the taxonomic position of the isolate in the genus Micromonospora. DNA–DNA relatedness values supported the classification of this isolate as a novel species. A number of physiological and biochemical tests were able to distinguish strain WA201T from its closest phylogenetic neighbours. Therefore, it is proposed that isolate WA201T (=DSM 44830T=LMG 22229T) be considered the type strain representing a novel species, Micromonospora mirobrigensis sp. nov.

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 novel actinomycete, designated strain GUI 15T, isolated from the root nodules of a Pisum sativum plant was characterized taxonomically by using a polyphasic approach. The 16S rRNA gene sequence of strain GUI 15T showed highest similarity to Micromonospora pattaloongensis TJ2-2T (98.7 %) and Polymorphospora rubra TT 97-42T (98.5 %). Phylogenetic analysis based on the gyrase B gene also supported the close relationship of these three strains, but indicated that strain GUI 15T should be assigned to the genus Micromonospora. Chemotaxonomic results confirmed the position of the isolate in the genus Micromonospora, but revealed differences at the species level. The novel strain could be distinguished from recognized Micromonospora species by using a combination of physiological and biochemical tests. Based on these observations, strain GUI 15T is considered to represent a novel species of the genus Micromonospora, for which the name Micromonospora pisi sp. nov. is proposed. The type strain is GUI 15T (=DSM 45175T=LMG 24546T).

A Gram-negative, rod-shaped, non-motile, non-spore-forming, pink-pigmented bacterium, SV97T, was isolated from a wetland soil near Ny-Ålesund, Svalbard Islands, Norway (78° N). On the basis of 16S rRNA gene sequence similarity, strain SV97T was shown to belong to the Alphaproteobacteria and was highly related to a number of non-characterized Methylocystis strains with GenBank accession nos AJ458507 and AJ458502 (100 %) and AF177299, AJ458510, AJ458467, AJ458471, AJ431384, AJ458475, AJ458484, AJ458501 and AJ458466 (99 %). The most closely related type strains were Methylocystis parvus OBBPT (97·2 %) and Methylocystis echinoides IMET 10491T (97 %). The closest related recognized species within the genus Methylosinus was Methylosinus sporium NCIMB 11126T (96·0 % similarity). Chemotaxonomic and phenotypic data (C18 : 1 ω8 as the major fatty acid, non-motile, no rosette formation) supported the affiliation of strain SV97T to the genus Methylocystis. The results of DNA–DNA hybridization and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain SV97T from the two recognized Methylocystis species. Strain SV97T therefore represents a novel species, for which the name Methylocystis rosea sp. nov. is proposed, with the type strain SV97T (=DSM 17261T=ATCC BAA-1196T).

Two strains of gliding, agarolytic bacteria, strains YS10T and YML5, were isolated from coastal seawater off Kamogawa, Japan. Phylogenetic analysis based on 16S rRNA gene sequences showed that the novel isolates represent a separate lineage within the genus Flammeovirga. DNA–DNA hybridization values between these isolates and the type strains of species of the genus Flammeovirga were significantly lower than those accepted as threshold values for the phylogenetic definition of a species. Furthermore, some of the phenotypic characteristics indicate that the isolates differ from other Flammeovirga species. Based on these differences, it is suggested that the isolates represent a novel species, for which the name Flammeovirga kamogawensis sp. nov. is proposed. The type strain is YS10T (=IAM 15451T=NCIMB 14281T).

A Gram-negative, rod-shaped bacterial strain, designated K19414T, was isolated from a chironomid (Diptera; Chironomidae) egg mass which was sampled from Kishon River in northern Israel. Phylogenetic analysis based on the 16S rRNA gene sequence positioned the novel strain among the genus Rheinheimera, with closest similarity to Rheinheimera pacifica KMM 1406T. The levels of similarity to type strains of Rheinheimera species were lower than 96.5 %. Isolate K19414T is aerobic, motile by means of a single polar flagellum, catalase-negative and oxidase-positive; growth was observed at salinities of 0–2 % NaCl and the temperature for growth ranged from 4 to 40 °C. The major cellular fatty acids are 16 : 0 (14.8 %) and 16 : 1ω7c and/or 15 : 0 iso 2-OH (25.76 %). The DNA G+C content is 49.9 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain K19414T (=LMG 23818T =DSM 18694T) was classified in the genus Rheinheimera as the type strain of a novel species, for which the name Rheinheimera chironomi sp. nov. is proposed.

The taxonomic position of strain JL-22T, isolated from litter of a bamboo (Sasa borealis) forest, was determined using a polyphasic approach. The organism had phenotypic and morphological properties consistent with it being a member of the genus Streptomyces . Phylogenetic analysis of the 16S rRNA gene sequence showed that strain JL-22T was closely related to Streptomyces prunicolor NRRL B-12281T (99.2 %), Streptomyces galilaeus JCM 4757T (99.0 %) and Streptomyces chartreusis NBRC 12753T (99.0 %). However, the results of DNA–DNA hybridization and physiological and biochemical tests showed that strain JL-22T could be differentiated from its closest phylogenetic relatives both genotypically and phenotypically. Based on phenotypic and genotypic data, strain JL-22T represents a novel species of the genus Streptomyces , for which the name Streptomyces graminifolii sp. nov. is proposed. The type strain is JL-22T ( = KACC 17180T = NBRC 109806T).

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).

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 bacterium, designated strain DCY01T, 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 DCY01T belonged to the Gammaproteobacteria and was most closely related to Stenotrophomonas koreensis KCTC 12211T (98.4 % similarity), Stenotrophomonas humi R-32729T (97.2 %), Stenotrophomonas terrae R-32768 (97.1 %), Stenotrophomonas maltophilia DSM 50170T (96.9 %) and Stenotrophomonas nitritireducens DSM 12575T (96.8 %). 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.
