An obligately aerobic, spherical, non-motile, pale-yellow pigmented bacterium was isolated from a piece of leaf of seagrass, Enhalus acoroides (L.f.) Royle, grown in Okinawa, Japan and was subjected to a polyphasic taxonomic study. Phylogenetic analyses based on 16S rRNA gene sequences revealed that the novel isolate N5FB36-5T shared approximately 96–98 % sequence similarity with the species of the genus Pelagicoccus of the family Puniceicoccaceae within the phylum ‘Verrucomicrobia’. The DNA–DNA relatedness values of strain N5FB36-5T with Pelagicoccus mobilis 02PA-Ca-133T and Pelagicoccus albus YM14-201T were below 70 %, which is accepted as the phylogenetic definition of a novel species. β-Lactam antibiotic susceptibility test and amino acid analysis of the cell wall hydrolysates indicated the absence of muramic acid and diaminopimelic acid in the cell walls, which suggested that this strain lacks an ordinary Gram-negative type of peptidoglycan in the cell wall. The DNA G+C content of strain N5FB36-5T was 51.6 mol%; MK-7 was the major menaquinone; and the presence of C16 : 0, C16 : 1 ω7c and anteiso-C15 : 0 as the major cellular fatty acids supported the identification of the novel isolate as a member of the genus Pelagicoccus. On the basis of polyphasic taxonomic data, it was concluded that this strain should be classified as a novel species of the genus Pelagicoccus, for which the name Pelagicoccus croceus sp. nov. is proposed. The type strain is N5FB36-5T (=MBIC08282T=KCTC 12903T).

An actinomycete strain, HM7T, was isolated from sandy soil from the banks of the Arvand River, Khoramshahr, Iran. In a study conducted using a polyphasic taxonomic approach, it was found that this strain represented a novel species in the genus Nocardiopsis. Strain HM7T had long, branched substrate mycelia and the aerial mycelium completely fragmented to long chains of rod-shaped spores. The cell wall of strain HM7T contained meso-diaminopimelic acid, galactose and ribose. The predominant phospholipids were phosphatidylglycerol, phosphatidylethanolamine diphosphatidylglycerol, and phosphatidylcholine. The main menaquinones were MK-10(H2), MK-10(H4), MK-10(H0) and MK-9(H2). Strain HM7T showed the highest degree of 16S rRNA gene sequence similarity with Nocardiopsis sinuspersici UTMC 00102T (99.8 %) and Nocardiopsis quinghaiensis YIM 28A4T (99.3 %), but differed significantly from these type strains based on DNA–DNA hybridization data (37.6 and 38.9 % relatedness, respectively). Physiological, biochemical and phenotypic characteristics allowed strain HM7T to be differentiated from related species. On the basis of results from phenotypic and phylogenetic analyses, strain HM7T is considered to represent a novel species of the genus Nocardiopsis, for which the name Nocardiopsis arvandica sp. nov. is proposed; the type strain of this species is HM7T ( = UTMC 00103T = DSM 45278T = CCUG 58831T).

Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48T and KYW147T, were isolated from seawater collected from the South Sea, Republic of Korea. Cells of both strains were Gram-reaction-negative, aerobic and catalase- and oxidase-positive. The major fatty acids of strain KYW48T were C18 : 1ω7c (35.3 %), summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c) (22.7 %), C17 : 1ω6c (19.8 %), C14 : 0 2-OH (7.4 %) and C16 : 0 (5.9 %), and those of strain KYW147T were C18 : 1ω7c (36.0 %), summed feature 3 (18.3 %), C16 : 0 (14.7 %), 11-methyl C18 : 1ω7c (10.7 %), C16 : 0 2-OH (9.1 %) and C18 : 1ω9c (8.0 %). The predominant isoprenoid quinone of both strains was ubiquinone 10 (Q-10). The DNA G+C contents of strains KYW48T and KYW147T were 63.8 and 67.2 mol%, respectively. A phylogenetic tree based on 16S rRNA gene sequences showed that strains KYW48T and KYW147T were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with the members of the genus Altererythrobacter (<95.7 % sequence similarity). On the basis of the evidence presented in this study, the novel species Altererythrobacter namhicola sp. nov. (type strain KYW48T  = KCTC 22736T  = JCM 16345T) and Altererythrobacter aestuarii sp. nov. (type strain KYW147T  = KCTC 22735T  = JCM 16339T) are proposed.

A Gram-positive, rod-shaped, non-spore-forming and strictly aerobic bacterium (Gsoil 161T) was isolated from soil of a ginseng field in Pocheon Province, South Korea. The novel isolate was characterized using a polyphasic approach in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity, strain Gsoil 161T was shown to belong to the family Nocardioidaceae and was related to Aeromicrobium marinum (98.0 % similarity to the type strain), Aeromicrobium alkaliterrae (97.6 %), Aeromicrobium fastidiosum (97.0 %) and Aeromicrobium erythreum (96.7 %); the sequence similarity with other species within the family was less than 94.4 %. It was characterized chemotaxonomically as having ll-2,6-diaminopimelic acid in the cell-wall peptidoglycan, MK-9(H4) as the predominant menaquinone and C16 : 0, 10-methyl C18 : 0 (tuberculostearic acid), C16 : 0 2-OH, 10-methyl C17 : 0 and 10-methyl-C16 : 0 as the major fatty acids. The G+C content of the genomic DNA was 65.5 mol%. These chemotaxonomic properties and phenotypic characteristics support the affiliation of strain Gsoil 161T to the genus Aeromicrobium. Results of physiological and biochemical tests enabled strain Gsoil 161T to be differentiated genotypically and phenotypically from currently known Aeromicrobium species. Therefore, strain Gsoil 161T represents a novel species, for which the name Aeromicrobium panaciterrae sp. nov. is proposed. The type strain is strain Gsoil 161T (=KCTC 19131T=DSM 17939T=CCUG 52476T).

Three short spore chain-forming actinomycete strains were isolated from soil samples collected from subtropical islands in Japan. The cell-wall peptidoglycan of these strains contained meso-diaminopimelic acid (meso-A2pm), glutamic acid and alanine. The major isoprenoid quinone was MK-9(H4), iso-C16 : 0 and 2-OH iso-C16 : 0 were the major cellular fatty acids and phosphatidylethanolamine was a component of the polar lipids. The G+C content of the genomic DNA was 67–69 mol%. Phylogenetic analyses based on the 16S rRNA gene sequences showed that the novel strains consistently formed a monophyletic cluster with Amycolatopsis taiwanensis. On the basis this polyphasic taxonomical study, it is proposed that the two new isolates represent two novel species: Amycolatopsis helveola (type strain TT00-43T=NBRC 103394T=KCTC 19329T) and Amycolatopsis pigmentata (type strain TT99-32T=NBRC 103392T=KCTC 19330T).
