A polyphasic study was undertaken to establish the taxonomic status of a soil isolate. The organism, strain FXJ14T, was found to have chemical and morphological properties characteristic of streptomycetes. Phylogenetic analyses based on an almost complete 16S rRNA gene sequence of the strain and on the 120 nt variable γ-region of the 16S rRNA molecule showed that it formed a distinct phyletic line within the range of variation encompassed by the genus Streptomyces. The sharp separation of the organism from representatives of the genus Streptomyces was strengthened by the fact that its BOX-PCR and RFLP of 16S rDNA-ITS fingerprints differed from those of over 450 recognized Streptomyces species. The isolate also had a profile of phenotypic properties that readily distinguished it from the genotypically close type strains. It is evident from the combination of genotypic and phenotypic data that strain FXJ14T (=AS 4.1858T=JCM 12278T=LMG 22082T) should be classified as the type strain of a novel species of the genus Streptomyces, for which the name Streptomyces glauciniger sp. nov. is proposed.

A polyphasic study was undertaken to determine the taxonomic status of six strains received as Streptomyces hygroscopicus. The strains had chemotaxonomic and morphological properties typical of members of the genus Streptomyces and formed distinct phyletic lines in the Streptomyces 16S rRNA gene tree. These strains were distinguished from one another and from phylogenetically close neighbours using a combination of phenotypic properties. The combined genotypic and phenotypic data showed that all six strains form distinct centres of taxonomic variation within the genus Streptomyces. The following novel species are proposed to accommodate the strains: Streptomyces aldersoniae sp. nov. (type strain DSM 41909T =NRRL 18513T), Streptomyces angustmyceticus sp. nov., comb. nov. (type strain DSM 41683T=NRRL B-2347T), Streptomyces ascomycinicus sp. nov. (type strain DSM 40822T =NBRC 13981T), Streptomyces decoyicus sp. nov., comb. nov. (type strain DSM 41427T =NRRL 2666T), Streptomyces milbemycinicus sp. nov. (type strain DSM 41911T =NRRL 5739T) and Streptomyces wellingtoniae sp. nov. (type strain DSM 40632T =NRRL B-1503T).

The taxonomic status of an actinomycete isolated from sediment collected from the Mariana Trench was established using a combination of genotypic and phenotypic data. Isolate MT8T had chemotaxonomic and morphological properties consistent with its classification in the genus Williamsia, and formed a distinct phyletic line in the 16S rRNA gene tree together with the type strain of Williamsia muralis. The isolate was readily distinguished from the latter, and from representatives of other Williamsia species, using DNA–DNA relatedness and phenotypic criteria. Predominant cellular fatty acids were oleic, palmitic and tuberculostearic acids and a hexadecenoic acid. The DNA G+C content was 65.2 mol%. It is apparent that the isolate belongs to a novel species of Williamsia. Strain MT8T (=DSM 44944T=NCIMB 14085T) was thus considered to be the type strain of a novel species in the genus Williamsia, for which the name Williamsia marianensis sp. nov. is proposed.

The taxonomic status of an actinomycete isolated from soil collected from a hay meadow was determined using a polyphasic approach. The strain, designated N1350T, had morphological and chemotaxonomic properties consistent with its classification in the genus Williamsia and formed a distinct phyletic line within the clade comprising the type strains of species of the genus Williamsia in the 16S rRNA gene tree. Strain N1350T shared highest 16S rRNA gene sequence similarities with Williamsia marianensis MT8T (98.1 %) and Williamsia muralis MA140-96T (98.3 %). However, strain N1350T was readily distinguished from the type strains of Williamsia species using a combination of phenotypic properties. On the basis of these data, strain N1350T is considered to represent a novel species of the genus Williamsia. The name proposed for this taxon is Williamsia faeni sp. nov., with the type strain N1350T (=DSM 45372T =NCIMB 14575T =NRRL B-24794T).

Forty strains isolated from soil taken from a hay meadow were assigned to the genus Dactylosporangium on the basis of colonial properties. 16S rRNA gene sequence analysis showed that the isolates formed a group that was most closely related to the type strain of Dactylosporangium aurantiacum, but well separated from other Dactylosporangium type strains and from ‘Dactylosporangium salmoneum’ NRRL B-16294. Twelve of 13 representative isolates had identical 16S rRNA gene sequences and formed a subclade that was distinct from corresponding phyletic lines composed of the remaining isolate, strain BK63T, the ‘D. salmoneum’ strain and the type strains of recognized Dactylosporangium species. DNA–DNA relatedness data indicated that representatives of the multi-membered 16S rRNA gene subclade, isolate BK63T and the ‘D. salmoneum’ subclade formed distinct genomic species; all of these organisms had chemotaxonomic and morphological properties consistent with their classification in the genus Dactylosporangium. They were also distinguished from one another and from the type strains of recognized Dactylosporangium species based on a range of phenotypic properties. Combined genotypic and phenotypic data showed that isolate BK63T, isolates BK51T, BK53 and BK69, and strain NRRL B-16294T should be classified in the genus Dactylosporangium as representing novel species. The names proposed for these species are Dactylosporangium luridum sp. nov. (type strain BK63T  = DSM 45324T  = KACC 20933T  = NRRL B-24775T), Dactylosporangium luteum sp. nov. (type strain BK51T  = DSM 45323T  = KACC 20899T  = NRRL B-24774T) and Dactylosporangium salmoneum sp. nov., nom. rev. (type strain NRRL B-16294T  = ATCC 31222T  = DSM 43910T  = JCM 3272T  = NBRC 14103T).

The taxonomic position of a soil isolate, strain Z6T, was established using a polyphasic approach. The organism showed a range of chemical and morphological properties consistent with its classification in the genus Lechevalieria. An almost complete 16S rRNA gene sequence determined for the strain was aligned with corresponding sequences of representatives of the genus Lechevalieria and related taxa using three tree-making algorithms. The organism formed a distinct phyletic line within the evolutionary radiation occupied by the genus Lechevalieria and was more closely related to the type strain of Lechevalieria aerocolonigenes than to that of Lechevalieria flava. Strain Z6T could be distinguished from both these strains using DNA–DNA relatedness data and by a combination of phenotypic properties. The combined genotypic and phenotypic data show that strain Z6T should be assigned to the genus Lechevalieria as a representative of a novel species. The name proposed for this new taxon is Lechevalieria fradiae sp. nov. The type strain is Z6T (=CGMCC 4.3506T=JCM 14205T).

The taxonomic status of the families Actinosynnemataceae and Pseudonocardiaceae was assessed based on 16S rRNA gene sequence data available for the 151 taxa with validly published names, as well as chemotaxonomic and morphological properties available from the literature. 16S rRNA gene sequences for the type strains of all taxa within the suborder Pseudonocardineae were subjected to phylogenetic analyses using different algorithms in arb and phylip. The description of many new genera and species within the suborder Pseudonocardineae since the family Actinosynnemataceae was proposed in 2000 has resulted in a markedly different distribution of chemotaxonomic markers within the suborder from that observed at that time. For instance, it is noted that species of the genera Actinokineospora and Allokutzneria contain arabinose in whole-cell hydrolysates, which is not observed in the other genera within the Actinosynnemataceae, and that there are many genera within the family Pseudonocardiaceae as currently described that do not contain arabinose. Phylogenetic analyses of 16S rRNA gene sequences for all taxa within the suborder do not provide any statistical support for the family Actinosynnemataceae, nor are signature nucleotides found that support its continued differentiation from the family Pseudonocardiaceae. The description of the family Pseudonocardiaceae is therefore emended to include the genera previously classified within the family Actinosynnemataceae and the description of the suborder Pseudonocardineae is also emended to reflect this reclassification.

The taxonomic position of an actinomycete isolated from an ultramafic soil in New Caledonia was determined using a polyphasic approach. The isolate, which was designated SFOp68T, was shown to have chemical and morphological properties typical of streptomycetes. An almost complete 16S rRNA gene sequence of the isolate was generated and compared with sequences of representative streptomycetes. The 16S rRNA data not only supported the classification of the strain in the genus Streptomyces, but also showed that it formed a distinct phyletic line that was most closely related to one composed of the type strain of Streptomyces rimosus. The two organisms can be readily separated using a diverse range of phenotypic properties. It is proposed that strain SFOp68T (=DSM 41836T=NCIMB 13954T) be classified in the genus Streptomyces as Streptomyces ferralitis sp. nov.

The taxonomic position of an actinomycete isolated from radiation-polluted soil collected in Xinjiang Province, north-west China, was determined by using a polyphasic approach. The isolate, designated strain R97T, had chemical and morphological properties characteristic of streptomycetes. An almost-complete 16S rRNA gene sequence of the isolate was generated and compared with corresponding sequences of representative streptomycetes. The 16S rRNA data not only supported the classification of the strain in the genus Streptomyces but also showed that it represented a distinct phyletic line that was most closely, albeit loosely, associated with three other thermotolerant organisms, namely Streptomyces macrosporus NBRC 14748T, Streptomyces megasporus NBRC 14749T and Streptomyces thermolineatus NBRC 14750T. Strain R97T could be distinguished from these organisms based on a range of phenotypic properties. It is proposed that R97T (=CGMCC 4.3519T =DSM 41901T) be classified as the type strain of a novel species in the genus Streptomyces, Streptomyces radiopugnans sp. nov. The organism was shown to be resistant to 60Co gamma radiation at a dose of 15 kGy.

A novel actinobacteria, designated strain K413T, was isolated from soil collected from Karpaz National Park, Magusa, Northern Cyprus, and characterized to determine its taxonomic position. The isolate was found to have chemical and morphological properties associated with members of the genus Streptomyces . Phylogenetic analyses based on almost-complete 16S rRNA gene sequences indicated that the isolate was closely related to members of the genus Streptomyces , and was shown to form a distinct phyletic line in the Streptomyces phylogenetic tree. Strain K413T was most closely related to Streptomyces marinus DSM 41968T (98.01 %). Sequence similarities with other strains of the genus Streptomyces were below 98.0 %. The cell wall of the novel strain contained ll-diaminopimelic acid. The predominant menaquinone was MK-9(H8) (45.0 %). The polar lipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine and phosphatidylinositol. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. Based on 16S rRNA gene sequence analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data, strain K413T represents a novel species of the genus Streptomyces , for which the name Streptomyces karpasiensis sp. nov. is proposed. The type strain is K413T ( = KCTC 29096T = DSM 42068T).

The taxonomic position of a soil isolate, strain 276T, was established using a polyphasic approach. The organism showed a range of chemical and morphological properties consistent with its classification in the genus Nocardia. An almost complete 16S rRNA gene sequence determined for the strain was aligned with corresponding sequences of representatives of the genus Nocardia and related taxa using three tree-making algorithms. The organism formed a distinct phyletic line within the evolutionary radiation occupied by the genus Nocardia and was most closely related to the type strain of Nocardia abscessus. However, the two strains shared a low DNA–DNA relatedness value and were readily distinguished using a combination of phenotypic properties. The combined genotypic and phenotypic data show that strain 276T should be assigned to the genus Nocardia as a novel species. The name proposed for this new taxon is Nocardia xishanensis sp. nov. The type strain is 276T (=CGMCC 4.1860T=JCM 12160T).
