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 positions of two actinomycetes isolated from a hay meadow soil sample were determined using a polyphasic approach. The isolates had chemical and morphological properties typical of streptomycetes and formed a distinct 16S rRNA gene subclade together with the type strain Streptomyces drozdowiczii NRRL B-24297T. DNA–DNA relatedness studies showed that the three strains belonged to different genomic species. The organisms were also distinguished using a combination of phenotypic properties. On the basis of these data it is proposed that the isolates be assigned to the genus Streptomyces as Streptomyces brevispora sp. nov. and Streptomyces laculatispora sp. nov., with BK160T ( = KACC 21093T  = NCIMB 14702T) and BK166T ( = KACC 20907T  = NCIMB 14703T) as the respective type strains.

A Gram-stain-positive, facultatively anaerobic, non-spore-forming, non-flagellated and rod-shaped or ovoid bacterial strain, designated BS-12MT, was isolated from a tidal flat sediment on the South Sea, South Korea. Strain BS-12MT grew optimally at 35 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain BS-12MT fell within the cluster comprising the type strains of species of the genus Demequina, joining the type strain of Demequina aestuarii with which it shared the highest sequence similarity (98.6 %). It exhibited 16S rRNA gene sequence similarity of 96.1–97.9 % to the type strains of other species of the genus Demequina. The peptidoglycan type of strain BS-12MT was A4β based on l-Orn − l-Ser − d-Glu. Strain BS-12MT contained demethylmenaquinone-9(H4) as the major menaquinone and anteiso-C15:0 and C16:0 as the major fatty acids. The major polar lipids of strain BS-12MT were phosphatidylinositol and phosphatidylinositolmannoside. The DNA G+C content of strain BS-12MT was 70.7 mol% and its DNA–DNA relatedness values with the type strains of five phylogenetically related species of the genus Demequina were 15–34 %. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain BS-12MT is separate from other species of the genus Demequina. On the basis of the data presented, strain BS-12MT is considered to represent a novel species of the genus Demequina, for which the name Demequina activiva sp. nov. is proposed. The type strain is BS-12MT ( = KCTC 29674T = NBRC 110675T).

ABSTRACT A Gram-stain-negative bacterial strain, JBTF-M27T, was isolated from a tidal flat from Yellow Sea, Republic of Korea. Neighbor-joining phylogenetic tree of 16S rRNA gene sequences showed that strain JBTF-M27T fell within the clade comprising the type strains of Sulfitobacter species. Strain JBTF-M27T exhibited the highest 16S rRNA gene sequence similarity (98.8%) to the type strain of S. porphyrae. Genomic ANI and dDDH values of strain JBTF-M27T between the type strains of Sulfitobacter species were less than 76.1 and 19.2%, respectively. Mean DNA-DNA relatedness value between strain JBTF-M27T and the type strain of S. porphyrae was 21%. DNA G + C content of strain JBTF-M27T from genome sequence was 57.8% (genomic analysis). Strain JBTF-M27T contained Q-10 as the predominant ubiquinone and C18:1ω7c as the major fatty acid. The major polar lipids of strain JBTF-M27T were phosphatidylcholine, phosphatidylglycerol and one unidentified aminolipid. Distinguished phenotypic properties, along with the phylogenetic and genetic distinctiveness, revealed that strain JBTF-M27T is separated from recognized Sulfitobacter species. On the basis of the data presented, strain JBTF-M27T ( = KACC 21648T = NBRC 114356T) is considered to represent a novel species of the genus Sulfitobacter, for which the name Sulfitobacter sediminilitoris sp. nov. is proposed.

The taxonomic positions of two thermophilic actinomycetes isolated from an arid Australian soil sample were established based on an investigation using a polyphasic taxonomic approach. The organisms had chemical and morphological properties typical of members of the genus Amycolatopsis and formed distinct phyletic lines in the Amycolatopsis methanolica 16S rRNA subclade. The two organisms were distinguished from one another and from the type strains of related species of the genus Amycolatopsis using a range of phenotypic properties. Based on the combined genotypic and phenotypic data, it is proposed that the two isolates be classified in the genus Amycolatopsis as Amycolatopsis thermophila sp. nov. (type strain GY088T = NCIMB 14699T = NRRL B-24836T) and Amycolatopsis viridis sp. nov. (type strain GY115T = NCIMB 14700T = NRRL B-24837T).
