A novel actinomycete strain, 7402J-48T, was isolated from an air sample collected from Jeju island, Republic of Korea. Cells were Gram-positive, aerobic, flagellated, short rods. Strain 7402J-48T showed highest 16S rRNA gene sequence similarity (98.6 %) with Angustibacter luteus TT07R-79T, and had relatively low sequence similarities (below 95.1 %) with other members of the family Kineosporiaceae . The cell wall of strain 7402J-48T contained alanine, glutamic acid and 2,6-diaminopimelic acid, suggesting A1γ-type peptidoglycan. The menaquinones were MK-9(H4) and MK-8(H4). The acyl type of the cell-wall muramic acid was acetyl. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside and an unknown lipid were present. The cellular fatty acid profile comprised a large amount of anteiso-C15 : 0, moderate amounts of C16 : 0, summed feature 3 (including C16 : 1ω7c and/or C16 : 1ω6c), C17 : 0, iso-C15 : 0, C16 : 0 N alcohol and C17 : 1ω8c, and small amounts of other fatty acids. The DNA G+C content of strain 7402J-48T was 73 mol%. Based on its phenotypic and genotypic characteristics, strain 7402J-48T ( = KACC 15527T = NBRC 108730T) is proposed as the type strain of a novel species, Angustibacter aerolatus sp. nov. An emended description of the genus Angustibacter is provided.

Three novel actinomycete strains, designated as DR6-1T, DR6-2 and DR6-4, isolated from the roots of Dendrobium heterocarpum Lindl in Thailand were studied using a polyphasic taxonomic approach. The strains grew at 20–37 °C, at pH 5–10 and with 5 % (w/v) NaCl. They contained meso-diaminopimelic acid in the cell-wall peptidoglycan and MK-9(H4) was a major menaquinone. Arabinose and galactose were the major sugars in the cell wall. The predominant cellular fatty acids were iso-C16 : 0 and iso-C15 : 0. The detected polar lipids were diphosphatidylglycerol, hydroxyphosphatidylethanolamine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylglycerol. Strains DR6-1T, DR6-2 and DR6-4 shared 99.9–100 % 16S rRNA gene sequence similarity and were closely related to Amycolatopsis echigonensis JCM 21831T (98.7-98.8%). The approximate genome size of strain DR6-1T was 9.6 Mb with a G+C content of 69.6 mol%. The ANIb and dDDH values between genomic sequences of strain DR6-1T and Amycolatopsis echigonensis JCM21831T, Amycolatopsis rubida JCM 10871T and Amycolatopsis nivea KCTC 39515T were 90.55, 92.25, 92.60%, and 47.20, 52.10 and 52.50%, respectively. Based on the phenotypic, chemotaxonomic and genotypic characteristics, it has been concluded that strains DR6-1T, DR6-2 and DR6-4 represent a novel species of the genus Amycolatopsis for which the name Amycolatopsis dendrobii sp. nov. is proposed. The type strain is DR6-1T (=JCM 33742T=KCTC 49546T=TISTR 2840T).

In this study, the taxonomic position of an actinobacterium, strain YIM M 10931T, which was isolated from a mangrove sediment sample collected in Dugong Creek, Little Andaman, India, was determined by a polyphasic approach. This Gram-positive, aerobic strain produced branched substrate mycelium and aerial hyphae, which differentiated into short, hooked or spiral spore chains. The organism contained meso-diaminopimelic acid as the diagnostic diamino acid in the cell-wall peptidoglycan. The whole cell sugars consisted of mannose, ribose, glucose, galactose and madurose. The cellular fatty acid profile mainly consisted of iso-C16 : 0, 10-methyl C18 : 0 and C16 : 0. The quinone system was predominantly composed of MK-9(H8) (45.5 %) and MK-9(H6) (39 %). The phospholipids detected were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol and two unknown phospholipids. The organism showed a combination of morphological and chemotaxonomic properties typical of members of the genus Actinomadura . Moreover, phylogenetic analysis based on a 16S rRNA gene sequence generated from the strain identified its closest relatives as Actinomadura cremea DSM 43676T (98.4 % sequence similarity), Actinomadura rifamycini DSM 43936T (97.4 %) and Actinomadura apis IM17-1T (96.9 %). It was obvious from the resulting phylogenetic trees that strain YIM M 10931T belongs to a distinct subclade within the evolutionary radiation of the genus Actinomadura . DNA–DNA hybridizations of strain YIM M 10931T with A. cremea DSM 43676T and A. rifamycini DSM 43936T were performed and further confirmed that the isolate represents a separate genomic species. Based on the phenotypic and genotypic characteristics presented, it is proposed that strain YIM M 10931T represents a novel species within the genus Actinomadura , for which the name Actinomadura sediminis sp. nov. is proposed; the type strain is YIM M 10931T ( = CCTCC AA 2010009T = DSM 45500T).

A facultatively alkaliphilic actinomycete strain, designated EGI 80088T, was isolated from a saline-alkali soil sample from Xinjiang province, north-west China, and subjected to a polyphasic taxonomic characterization. Strain EGI 80088T formed fragmented aerial hyphae and short spore chains, and rod-like spores aggregated at maturity. Whole-cell hydrolysates of the isolate contained ll-diaminopimelic acid as the diagnostic diamino acid, and glucosamine, mannose, galactose, glucose and rhamnose as the marker sugars. The major fatty acids identified (>5 %) were anteiso-C15 : 0, iso-C15 : 0, summed feature 4 (iso-C17 : 1I/anteiso-C17 : 1B), iso-C16 : 0 and anteiso-C17 : 0. The predominant menaquinone was MK-9(H4). The G+C content of the genomic DNA of strain EGI 80088T was 70.6 mol%. EGI 80088T showed the highest 16S rRNA gene sequence similarity to its closest phylogenetic neighbour Haloactinopolyspora alba YIM 93246T (98.5 %). The DNA–DNA relatedness value of the strain EGI 80088T and H. alba YIM 93246T was 59.3±5.2 %. On the basis of morphological, chemotaxonomic and phylogenetic characteristics and DNA–DNA hybridization data, strain EGI 80088T represents a novel species of the genus Haloactinopolyspora , for which the name Haloactinopolyspora alkaliphila sp. nov. (type strain EGI 80088T = BCRC 16946T = JCM 19128T) is proposed. The description of the genus Haloactinopolyspora has also been emended.

A novel Gram-stain-positive, spore-forming, aerobic, non-motile, rod-shaped bacterium designated strain SD111T that forms red-pigmented colonies was isolated from a marine sediment sample (collected from 5 m depth) from Lakshadweep, India. Strain SD111T grew well on seawater agar at pH 6–10 (optimum pH 7.5±0.2). It showed maximum (97.6 %) 16S rRNA gene sequence similarity and formed a monophyletic clade with Domibacillus robiginosus WS 4628T ( = DSM 25058T). The genomic DNA G+C content was 37.4 mol% and the strain showed 37.7 % DNA–DNA relatedness to D. robiginosus DSM 25058T. The major fatty acids were anteiso-C15 : 0, C16 : 0, iso-C15 : 0 and iso-C16 : 0 and MK-6 was the predominant quinone. The polar lipid profile of strain SD111T consisted of unidentified phospholipids (PL1 and PL2), phosphatidylglycerol (PG) and diphosphatidylglycerol (DPG). The cell wall contained meso-diaminopimelic acid and the peptidoglycan was of A1γ type. Glucose and ribose were detected as major cell-wall sugars. Results from polyphasic studies indicated that SD111T represents a novel species of the genus Domibacillus for which the name Domibacillus indicus sp. nov. is proposed. The type strain is SD111T ( = MCC 2255T = DSM 28032T).

A Gram-reaction-positive, non-spore-forming, aerobic actinobacterial strain (2C6-41T) was isolated from the activated sludge from an industrial wastewater treatment plant in Daegu, South Korea. Its taxonomic position was investigated by using a polyphasic approach. On the basis of 16S rRNA gene sequence similarity, closest phylogenetic relatives to strain 2C6-41T were Brevibacterium pityocampae DSM 21720T (97.2 %), Brevibacterium salitolerans KCTC 19616T (96.7 %), Brevibacterium album KCTC 19173T (96.2 %) and Brevibacterium samyangense KCCM 42316T (96.2 %). The DNA G+C content of strain 2C6-41T was 66.4 mol%. Chemotaxonomic data, which included MK-8(H2) as the major menaquinone; meso-diaminopimelic acid, glutamic acid and alanine as cell-wall amino acids; ribose, mannose and glucose as major cell-wall sugars; and anteiso-C15 : 0, anteiso-C17 : 0, C16 : 0 and iso-C15 : 0 as major fatty acids, supported the affiliation of strain 2C6-41T to the genus Brevibacterium . The aromatic ring cleavage enzyme catechol 1,2-dioxygenase was not detected in strain 2C6-41T, but catechol 2,3-dioxygenase was detected. The results of physiological and biochemical tests, and the low level of DNA–DNA relatedness to the closest phylogenetic relative enabled strain 2C6-41T to be differentiated genotypically and phenotypically from recognized species of the genus Brevibacterium . The isolate is therefore considered to represent a novel species in the genus Brevibacterium , for which the name Brevibacterium daeguense sp. nov. is proposed. The type strain is 2C6-41T ( = KCTC 19800T = JCM 17458T).

A filamentous actinomycete strain, designated GW9-2T, was isolated from a soil sample collected from the Fildes Peninsula, King George Island, West Antarctica. The strain was identified using a polyphasic taxonomic approach. The strain grew slowly on most media tested, producing small amounts of aerial mycelia and no diffusible pigments on most media tested. The strain grew in the presence of 0–12 % (w/v) NaCl (optimum, 2–4 %), at pH 9.0–11.0 (optimum, pH 9.0) and 10–37 °C (optimum, 28 °C). The isolate contained meso-diaminopimelic acid, no diagnostic sugars and MK-9(H4) as the predominant menaquinone. The major phospholipids were phosphatidylglycerol, phosphatidylcholine and phosphatidylmethylethanolamine. The major fatty acids were iso-C16 : 0, anteiso-C17 : 0, C18 : 1ω9c, iso-C15 : 0 and iso-C17 : 0. DNA–DNA relatedness was 37.6 % with Nocardiopsis lucentensis DSM 44048T, the nearest phylogenetic relative (97.93 % 16S rRNA gene sequence similarity). On the basis of the results of a polyphasic study, a novel species, Nocardiopsis fildesensis sp. nov., is proposed. The type strain is GW9-2T ( = CGMCC 4.7023T = DSM 45699T = NRRL B-24873T).
