A novel actinobacterial strain, designated CPCC 201356T, was isolated from a rhizosphere soil sample of the medicinal plant Astragalus membranaceus and subjected to a polyphasic taxonomic analysis. Good growth occurred at 20–32 °C, at pH 7.0–7.5 and with 0–1 % (w/v) NaCl. Colonies on R2A and ISP 2 agar were light red to red, round and lacked aerial mycelium; cells adhered to the agar. The peptidoglycan contained meso-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinones were MK-9(H4) and MK-9. Polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine and two unknown phospholipids. The major cellular fatty acids were iso-C16 : 0, iso-C15 : 0 and C17 : 1 ω8c. The G+C content of the genomic DNA was 72.8 mol%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain CPCC 201356T belonged to the family Geodermatophilaceae and consistently formed a distinct sub-branch with Geodermatophilus obscurus DSM 43160T. The organism showed 16S rRNA gene sequence similarity of 97.7 % with G. obscurus DSM 43160T. DNA–DNA hybridization between strain CPCC 201356T and G. obscurus DSM 43160T was 17.4 %. On the basis of evidence from this polyphasic taxonomic study, a novel species, Geodermatophilus ruber sp. nov., is proposed; the type strain is CPCC 201356T (=DSM 45317T =CCM 7619T).

Strain XMU 506T, isolated from the rhizosphere soil of an ornamental plant, Lantana camara L., collected from Xiamen City, China, was identified using a polyphasic approach to clarify its taxonomic position. The aerial mycelium of this organism formed long straight or curved chains of spores and sporangium-like structures. The optimum growth occurred at 28–30 °C, pH 7.0 with 0–1 % NaCl. Strain XMU 506T showed the highest 16S rRNA gene sequence similarity (96.5  %) to Kibdelosporangium philippinense DSM 44226T, and formed a monophyletic clade in the 16S rRNA gene phylogenetic tree together with the type strains of the genus Kibdelosporangium. The chemotaxonomic properties further supported the assignment of strain XMU 506T to the genus Kibdelosporangium: meso-diaminopimelic acid was the diagnostic amino acid in the cell wall peptidoglycan; mycolic acids were not present in the cell wall; the whole-cell hydrolysates contained arabinose, galactose, glucose and ribose. The major menaquinone was MK-9(H4); the phospholipids of the isolate comprised phosphatidylethanolamine, OH-phosphatidylethanolamine, diphosphatidylglycerol and unidentified amino-, glyco- and phospholipids; the major fatty acids of the strain were iso-C16 : 0, C17 : 1 ω6c and iso-C16 : 1 H. The G+C content of genomic DNA was 67.3 mol%. Based on the results of phylogenetic analysis, phenotypic and genotypic characterization, strain XMU 506T represents a novel species in the genus Kibdelosporangium, for which the name Kibdelosporangium lantanae sp. nov. is proposed. The type strain is XMU 506T ( = KCTC 29675T = MCCC 1K00430T).

A novel filamentous actinomycete strain, designated TRM 46004T, was isolated from sediment of Aiding Lake in Tulufan Basin (42° 64′ N 89° 26′ E), north-west China. The isolate was characterized using a polyphasic approach. The isolate formed abundant aerial mycelium with few branches and vegetative mycelium, occasionally twisted and coiled; spherical sporangia containing one to several spherical spores developed at the ends of short sporangiophores on aerial mycelium. The G+C content of the DNA was 65.2 mol%. The isolate contained meso-diaminopimelic acid as the diagnostic diamino acid and xylose, galactose and ribose as the major whole-cell sugars. The diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine and phosphatidylglycerol. The predominant menaquinones were MK-9(H4), MK-9(H6) and MK-9(H10). The major fatty acids were iso-C16 : 0 and anteiso-C17 : 0. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain TRM 46004T formed a distinct lineage within the family Pseudonocardiaceae and showed 91.7–96.1 % 16S rRNA gene sequence similarity with members of the family Pseudonocardiaceae . On the basis of the evidence from this polyphasic study, a novel genus and species, Longimycelium tulufanense gen. nov., sp. nov., are proposed. The type strain of Longimycelium tulufanense is TRM 46004T ( = CGMCC 4.5737T = NBRC 107726T).

The taxonomic position of a rhizosphere soil isolate, designated strain SR8.15T, was determined by using a polyphasic approach. Phylogenetic analysis based on an almost-complete 16S rRNA gene sequence of the strain showed that it formed a well-separated sub-branch within the radiation encompassing the genus Saccharopolyspora. Highest levels of 16S rRNA gene sequence similarity were found between strain SR8.15T and Saccharopolyspora shandongensis CGMCC 4.3530T (98.9 %) and Saccharopolyspora spinosa DSM 44228T (98.5 %). However, these strains shared low levels of DNA–DNA relatedness (<26 %). Strain SR8.15T had chemical characteristics consistent with its classification in the genus Saccharopolyspora. It contained meso-diaminopimelic acid as the diagnostic diamino acid. Whole-cell hydrolysates contained arabinose and galactose. The diagnostic phospholipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylinositol. The main menaquinone was MK-9(H4). No mycolic acid was detected. The predominant cellular fatty acid was iso-C16 : 0. The G+C content of the genomic DNA of strain SR8.15T was 70.3 mol%. Strain SR8.15T had a phenotypic profile that readily distinguished it from recognized representatives of the genus Saccharopolyspora. It is evident from its combined genotypic and phenotypic properties that strain SR8.15T represents a novel species of the genus Saccharopolyspora, for which the name Saccharopolyspora phatthalungensis sp. nov. is proposed. The type strain is SR8.15T (=TISTR 1921T=BCC 35844T=NRRL B-24798T).

A novel alphaproteobacterial strain, designated CPCC 100156T, was isolated from a forest soil sample collected from Hainan Island, South China, and subjected to taxonomic investigation using a polyphasic approach. The pink- to rosy-coloured colonies on TSA and YM agar were smooth and moist. Good growth occurred at 28–32 °C and at pH 7.0–7.5. The respiratory quinone was ubiquinone-9. The polar lipids consisted of phosphatidylcholine (PC), hydroxyphosphatidylethanolamine (OH-PE), phosphatidylglycerol (PG), diphosphatidylglycerol (DPG) and two unidentified aminolipids (AL1, AL2), with a minor amount of ninhydrin-positive phosphoglycolipid. (NPG). The major cellular fatty acids were summed feature 8 (C18 : 1ω7c /C18 : 1ω6c) (49.5 %), summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) (22.5 %), and C16 : 0 (14.0 %). The G+C content of the genomic DNA was 70.3 mol%. The organism showed 16S rRNA gene sequence similarity of 97.37 % with Belnapia moabensis DSM 16746T. Phylogenetic analyses based on 16S rRNA gene sequences showed that the isolate belonged to the family Acetobacteraceae and consistently formed a robust cluster with Belnapia moabensis DSM 16746T in the phylogenetic tree. The DNA–DNA hybridization value between the new isolate and Belnapia moabensis DSM 16746T was 45.6 %. On the basis of the taxonomic evidence, it is proposed that strain CPCC 100156T represents a novel species, for which the name Belnapia rosea sp. nov. is proposed. The type strain is CPCC 100156T ( = DSM 23312T = CGMCC 1.10758T). The description of the genus Belnapia is emended accordingly.

A Gram-positive, non-motile, rod-shaped actinomycete strain, designated SSW1-57T, was isolated from a dried seaweed sample from the coast of Jeju Island, Republic of Korea and subjected to a polyphasic taxonomic study. A neighbour-joining tree based on 16S rRNA gene sequences showed that the organism was related to members of the family Nocardioidaceae and formed a separate branch at the base of a taxon encompassing members of the genus Aeromicrobium, whereas it occupied an intermediate position between Aeromicrobium alkaliterrae–Aeromicrobium marinum and Aeromicrobium erythreum–Aeromicrobium fastidiosum clusters in maximum-parsimony and maximum-likelihood trees. The phylogenetic association of the isolate with the genus Aeromicrobium was supported by the following chemotaxonomic properties: ll-diaminopimelic acid in the peptidoglycan, MK-9(H4) as the major menaquinone and major fatty acids cis-9-octadecenoic acid, hexadecanoic acid, 10-methyl octadecanoic acid and 2-hydroxy hexadecanoic acid. The polar lipid profile contained phosphatidylinositol, diphosphatidylglycerol and phosphatidylglycerol. Levels of 16S rRNA gene sequence similarity between the novel organism and the type strains of the four recognized Aeromicrobium species were in the range 96.5–96.7 %. On the basis of phylogenetic analyses and phenotypic data, it is proposed that the organism should be classified as representing a novel species of the genus Aeromicrobium, with the name Aeromicrobium tamlense sp. nov. The type strain is SSW1-57T (=JCM 13811T=NRRL B-24466T).

A Gram-positive, non-motile and rod- or coccoid-shaped bacterial strain, MDN22T, was isolated from a soil sample from Korea. Strain MDN22T grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 0–0.5 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain MDN22T was phylogenetically most closely related to the genera Nocardioides and Marmoricola. In the neighbour-joining phylogenetic tree, strain MDN22T was most closely related to Nocardioides jensenii KCTC 9134T, with which it exhibited 98.3 % 16S rRNA gene sequence similarity. The strain exhibited 93.1–96.9 % and 95.3–95.9 % 16S rRNA gene sequence similarities to the type strains of other species of the genera Nocardioides and Marmoricola, respectively. The chemotaxonomic properties of strain MDN22T were consistent with those of the genus Nocardioides; the cell-wall peptidoglycan type was based on ll-2,6-diaminopimelic acid, the predominant menaquinone was MK-8(H4) and the major fatty acids were iso-C16 : 0 and C17 : 1. The DNA G+C content was 68.7 mol%. DNA–DNA relatedness data and differential phenotypic properties suggested that strain MDN22T could be differentiated from N. jensenii and Nocardioides dubius. On the basis of the data obtained, strain MDN22T is considered to represent a novel species of the genus Nocardioides, for which the name Nocardioides daedukensis sp. nov., is proposed. The type strain is MDN22T (=KCTC 19601T=CCUG 57505T).

An actinomycete strain, designated YU1183-22T, was isolated from a compost sample collected in Nikko, Japan. The isolate formed white aerial mycelium with relatively long aerial hyphae showing chains of arthrospores. Strain YU1183-22T grew with 0–10 % (w/v) NaCl, at pH 6–11 and at 10–37 °C (optimum 30 °C). Strain YU1183-22T contained meso-diaminopimelic acid and no diagnostic sugars. The predominant menaquinones were MK-10(H10) and MK-10(H8). The polar lipids were phosphatidylcholine and phosphatidylglycerol. The major cellular fatty acids were iso-C16 : 0, anteiso-C17 : 0 and tuberculostearic acid. The G+C content of the DNA was 72.3 mol%. Chemotaxonomic and morphological characterization clearly demonstrated that strain YU1183-22T belonged to the genus Nocardiopsis. Phylogenetic analysis using 16S rRNA gene sequences showed that the isolate was closely related to Nocardiopsis salina YIM 90010T (98.0 % 16S rRNA gene sequence similarity), Nocardiopsis xinjiangensis YIM 90004T (97.9 %) and Nocardiopsis kunsanensis HA-9T (97.3 %). However, DNA–DNA relatedness as well as physiological and biochemical analyses showed that strain YU1183-22T could be differentiated from its closest phylogenetic relatives. It is proposed that this strain be classified as a representative of a novel species of the genus Nocardiopsis, with the name Nocardiopsis nikkonensis sp. nov. The type strain is YU1183-22T (=NBRC 102170T =KCTC 19666T).

A Gram-positive, non-motile, coccoid-shaped, non-spore-forming halophilic bacterial strain, BY-5T, was isolated from a marine solar saltern in Korea and its taxonomic position was investigated by using a polyphasic approach. The novel strain grew optimally at 37 °C and in the presence of 10 % (w/v) NaCl. Strain BY-5T had meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan, MK-7 as the predominant menaquinone and anteiso-C15 : 0, iso-C15 : 0, anteiso-C17 : 0 and iso-C17 : 0 as the major fatty acids. The DNA G+C content was 47.9 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain BY-5T formed a coherent cluster with Bacillus halophilus and Marinococcus albus. Strain BY-5T exhibited 16S rRNA gene sequence similarity values of 98.7 and 97.4 % to the type strains of B. halophilus and M. albus, respectively. Strain BY-5T was distinguished from B. halophilus and M. albus by several phenotypic properties and DNA–DNA relatedness data. On the basis of the combined chemotaxonomic and phylogenetic data, it is proposed that M. albus, B. halophilus and strain BY-5T should be placed in a new genus as three separate species. Marinococcus albus and Bacillus halophilus are reclassified in a new genus, Salimicrobium gen. nov., as Salimicrobium album comb. nov. and Salimicrobium halophilum comb. nov., respectively. The type species of the new genus is Salimicrobium album. Strain BY-5T (=KCTC 3989T=CIP 108918T) is placed in the genus Salimicrobium as a novel species Salimicrobium luteum sp. nov.

A marine actinomycete strain, designated KSW2-15T, was isolated from a dried seaweed sample collected from a sandy beach on the coast of Jeju in the Republic of Korea. The organism produced non-motile, non-endospore-forming, Gram-positive, coccoid cells. The colonies were circular, translucent and yellow in colour with entire margins. meso-Diaminopimelic acid was present as the diamino acid of the peptidoglycan. The acyl type of the muramic acid was acetyl. Mycolic acids were not present. The predominant menaquinone was MK-8(H4). The polar lipids were phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were of the saturated, unsaturated and iso-branched methyl types. The DNA G+C content was 74 mol%. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain KSW2-15T formed a loose association with ‘Candidatus Nostocoida limicola’, within the radiation of the family Intrasporangiaceae of the suborder Micrococcineae. The organism showed the highest levels of sequence similarity with ‘Candidatus Nostocoida limicola’ (96.1 %), Terrabacter tumescens (96.1 %) and Terrabacter terrae (96.0 %). The levels of 16S rRNA gene sequence similarity between the isolate and members of other genera of the family Intrasporangiaceae were in the range 92.1–95.5 %. On the basis of the polyphasic evidence, the isolate should be classified within a novel genus and species, for which the name Phycicoccus jejuensis gen. nov., sp. nov. is proposed. The type strain of Phycicoccus jejuensis is strain KSW2-15T (=KCCM 42315T=NRRL B-24460T).

A novel Gram-stain-positive, aerobic, motile, non-spore-forming coccus-shaped actinomycete, designated strain YIM 121300T, was isolated from alkaline sediment in Yuanjiang, Yunnan province, south-west China. Phylogenetic analyses based on the 16S rRNA gene sequence showed that strain YIM 121300T was affiliated to the genus Kineococcus, and was closely related to Kineococcus aurantiacus IFO 15268T (97.3 % similarity). 16S rRNA gene sequence similarity to other species of the genus Kineococcus was < 97 %. The cell wall contained meso-diaminopimelic acid as the diagnostic diamino acid. The whole-cell sugars contained arabinose, galactose, glucose, mannose and ribose. The predominant menaquinone was MK-9(H2). Mycolic acids were not detected. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown phospholipid. The predominant fatty acids were anteiso-C15 : 0 and anteiso-C15 : 1 A. The G+C content of the genomic DNA was 75.1 mol%. DNA–DNA relatedness (55 ± 4 % to K. aurantiacus IFO 15268T) and differential phenotypic data demonstrated that strain YIM 121300T was distinguished from all related species of the genus Kineococcus. On the basis of data from the present polyphasic study, the organism should be assigned to a novel species of the genus Kineococcus, for which the name Kineococcus gypseus sp. nov. is proposed. The type strain is YIM 121300T ( = CCTCC AA 2013232T = DSM 27627T).
