A Streptomyces-like strain, 172205T, was obtained from mangrove soil collected at Qinglan Harbour, Wenchang, Hainan, China. The strain was characterized by white aerial mycelium and long spore chains. Comparison of 16S rRNA gene sequences indicated that the strain represents a novel member of the genus Streptomyces, exhibiting highest levels of similarity (<98.29 %) to the type strains of members of the genus Streptomyces. However, DNA–DNA relatedness and phenotypic data readily distinguished strain 172205T from phylogenetically related type strains. The predominant menaquinones were MK-9(H6) and MK-9(H8). The major fatty acids were iso-C15 : 0 (10.31 %), anteiso-C15 : 0 (35.19 %), iso-C16 : 0 (20.24 %) and anteiso-C17 : 0 (10.05 %). The diagnostic phospholipid was phosphatidylethanolamine. The cell wall contained ll-diaminopimelic acid and meso-diaminopimelic acid and whole-cell hydrolysates contained ribose, galactose and glucose. The results of DNA–DNA hybridization, physiological and biochemical tests allowed the genotypic and phenotypic differentiation of strain 172205T from phylogenetically related type strains. Therefore, strain 172205T is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces qinglanensis sp. nov. is proposed. The type strain is 172205T ( = CGMCC 4.6825T  = DSM 42035T).

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).

A Gram-stain-positive, coccoid, non-endospore-forming actinobacterium (strain CC-12602T) was isolated from a spawn used for growing the edible mushroom Agaricus brasiliensis in the laboratory. On the basis of 16S rRNA gene sequence analysis, strain CC-12602T was shown to belong to the genus Microlunatus and was related most closely to the type strains of Microlunatus ginsengisoli (96.1 % similarity), M. phosphovorus (95.9 %), M. panaciterrae (95.8 %) and M. aurantiacus (95.5 %). The quinone system comprised menaquinone MK-9(H4) as the major component and the polyamine pattern consisted of spermidine and spermine as major compounds. The predominant polar lipids were phosphatidylglycerol and unknown phospholipid PL3. Moderate amounts of diphosphatidylglycerol, an unknown glycolipid and three unknown phospholipids and minor amounts of an unknown phospholipid and a polar lipid were detected. The peptidoglycan type was A3γ′, based on ll-2,6-diaminopimelic acid with an interpeptide bridge consisting of a single glycine residue and a second glycine residue at position 1 of the peptide subunit. Peptidoglycan structure and major fatty acids (anteiso-C15 : 0, iso-C16 : 0 and iso-C15 : 0) supported the affiliation of strain CC-12602T to the genus Microlunatus. The results of physiological and biochemical tests allowed strain CC-12602T to be differentiated phenotypically from recognized Microlunatus species. Strain CC-12602T is therefore considered to represent a novel species of the genus Microlunatus, for which the name Microlunatus soli sp. nov. is proposed. The type strain is CC-12602T (=DSM 21800T =CCM 7685T).

An actinomycete, designated strain GIMN4.003T, was isolated from seawater collected in Sanya, China. It produced white aerial mycelium and yellow substrate mycelium on Gause’s synthetic agar medium no. 1. The substrate mycelium colour was not sensitive to pH. Scanning electron microscopy observations revealed that GIMN4.003T produced straight to flexuous spore chains of rough to warty spores. ll-Diaminopimelic acid was present in the cell-wall hydrolysate. Based on chemotaxonomy and morphological features, strain GIMN4.003T was identified as a member of the genus Streptomyces. Melanin was not produced. No antimicrobial activity was detected against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Penicillium citrinum or Candida albicans. Analysis of the 16S rRNA gene sequence revealed that the highest sequence similarity was to Streptomyces radiopugnans R97T (99.0 %). However, DNA relatedness between GIMN4.003T and S. radiopugnans DSM 41901T was low (41.24±1.47 %). Furthermore, the morphological, physiological and biochemical characteristics of strain GIMN4.003T were different from those of S. radiopugnans DSM 41901T and the type strains of other closely related Streptomyces species. On the basis of its physiological and molecular properties, it is evident that strain GIMN4.003T ( = CCTCCM 208215T  = NRRL B-24801T) represents the type strain of a novel species within the genus Streptomyces, for which the name Streptomyces fenghuangensis sp. nov. is proposed.

A Gram-stain-positive, rod-shaped, non-endospore-forming, orange-pigmented (coloured) actinobacterium (01-Je-003T) was isolated from the wall of an indoor environment primarily colonized with moulds. On the basis of 16S rRNA gene sequence similarity studies, strain 01-Je-003T was shown to belong to the genus Brevibacterium and was most similar to the type strains of Brevibacterium picturae (98.8 % similarity), Brevibacterium marinum (97.3 %) and Brevibacterium aurantiacum (97.2 %). Chemotaxonomic data [predominant quinone menaquinone MK-8(H2); polar lipid profile consisting of major compounds diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid; characteristic cell-wall diamino acid meso-diaminopimelic acid; polyamine pattern showing major compounds putrescine and cadaverine; major fatty acids anteiso-C15 : 0 and anteiso-C17 : 0] supported the affiliation of strain 01-Je-003T to the genus Brevibacterium. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 01-Je-003T from the two most closely related species, B. picturae and B. marinum. Strain 01-Je-003T therefore represents a novel species, for which the name Brevibacterium sandarakinum sp. nov. is proposed, with the type strain 01-Je-003T (=DSM 22082T =CCM 7649T).

A Gram-positive bacterium (strain CC-YMP-6T) was isolated from soil samples collected from Yang-Ming Mountain, Taiwan. On the basis of 16S rRNA gene sequence analysis, strain CC-YMP-6T clearly belonged to the genus Virgibacillus and was most closely related to the type strains of Virgibacillus halophilus (96.2 % similarity) and Virgibacillus kekensis (96.3 %). The predominant isoprenoid quinone was menaquinone MK-7 and the polar lipid profile was composed of the major components diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and one unidentified phospholipid plus moderate amounts of two unidentified aminophospholipids and a phospholipid. The polyamine pattern comprised spermidine as the single major component with spermine and putrescine present in minor amounts. The major fatty acids of strain CC-YMP-6T were iso-C15 : 0 and anteiso-C15 : 0. The results of physiological and biochemical tests allowed the clear phenotypic differentiation of strain CC-YMP-6T from all recognized species of the genus Virgibacillus. Strain CC-YMP-6T is therefore considered to represent a novel species of the genus Virgibacillus, for which the name Virgibacillus soli sp. nov. is proposed. The type strain is CC-YMP-6T (=DSM 22952T=CCM 7714T).

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-positive, aerobic, coccus-shaped, non-endospore-forming bacterium (Gsoil 633T) was isolated from soil from a ginseng field in Pocheon province in South Korea. The novel isolate was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarities, strain Gsoil 633T was shown to belong to the family Propionibacteriaceae. The closest phylogenetic relative was Microlunatus phosphovorus DSM 19555T, with 96.1 % sequence similarity; the sequence similarity to other members of the family was less than 95.4 %. The isolate was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 69.8 mol%. The morphological and chemotaxonomic properties of the isolate were consistent with those of M. phosphovorus, but the results of physiological and biochemical tests allowed the phenotypic differentiation of strain Gsoil 633T from this species. Therefore, strain Gsoil 633T represents a novel species, for which the name Microlunatus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 633T (=KCTC 13940T=DSM 17942T).

A Gram-positive, aerobic, non-motile actinomycete, strain MN08-A0203T, that formed pale yellow to orange-brown colonies and non-fragmented branched substrate mycelium is described. The strain, which produced very scanty aerial mycelium-like structures and scanty formation of spherical bodies on the aerial mycelium on Bennett’s agar medium, was studied in detail to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity studies, strain MN08-A0203T grouped with the genus Actinophytocola, being most closely related to the type strain of Actinophytocola oryzae (97.8 %). Chemotaxonomic data [menaquinone MK-9(H4); iso-C16 : 0 (27 %), iso-C15 : 0 (18 %), C16 : 1 H (8 %), C16 : 0 9-methyl (8 %) as major fatty acids; glucose, galactose, ribose, arabinose, mannose, rhamnose and xylose (trace) as whole cell sugars; diphosphatidylglycerol, phosphatidylethanolamine, hydroxyphosphatidylethanolamine and ninhydrin-positive phosphoglycolipids as polar phospholipids] supported allocation of the strain to the genus Actinophytocola. Furthermore, the results of DNA–DNA hybridization of strain MN08-A0203T with the type strain of Actinophytocola oryzae revealed that the two strains were genetically distinct from each other. Moreover, physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain MN08-A0203T from closely related species. Thus, MN08-A0203T represents a novel species of the genus Actinophytocola, for which the name Actinophytocola burenkhanensis sp. nov. is proposed, with MN08-A0203T ( = NBRC 105883T  = VTCC D9-23T) as the type strain.

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 novel actinomycete, strain X4T, was isolated from a phosphate mine in Youssoufia, 100 km north of Marrakesh, Morocco. The taxonomic status of this strain was evaluated by a polyphasic approach. Strain X4T had white aerial mycelium with Rectiflexibiles spore chains bearing smooth-surfaced spores and did not produce diffusible pigments. Chemotaxonomic analysis showed that the cell wall of strain X4T contained ll-diaminopimelic acid and glycine. Phylogenetic analysis based on the almost complete 16S rRNA gene sequence indicated that strain X4T belongs to the Group I streptomycetes, branching off next to Streptomyces ramulosus NRRL B-2714T and Streptomyces kasugaensis M338-M1T. DNA–DNA relatedness and phenotypic data enabled strain X4T to be distinguished from the phylogenetically most closely related type strains. It is therefore proposed that strain X4T represents a novel species of the genus Streptomyces, for which the name Streptomyces youssoufiensis sp. nov. is proposed; the type strain is X4T ( = CCMM B709T  = DSM 41920T).
