Strain T13T, isolated from forest soil in Jeollabuk-do, South Korea, exhibited antibiotic production on yeast extract-malt extract-glucose (YMG) medium containing magnesium chloride as a trace mineral, and inhibited the growth of Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa, Staphylococcus epidermidis, Paenibacillus larvae, Escherichia coli, Candida albicans and Aspergillus niger. Growth occurred at 15–45 °C, pH 4–11 and in the presence of up to 2 % (w/v) NaCl. Biochemical analyses indicated that the predominant menaquinones produced by this strain were MK-9(H6) and MK-9(H8); small amounts of MK-10(H2) and MK-10(H4) were also detected. The polar lipid profile comprised diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine, and the cell-wall peptidoglycan contained ll-diaminopimelic acid, glutamic acid, alanine and glycine. Whole-cell hydrolysates contained glucose, galactose, ribose and rhamnose. The fatty-acid profile of strain T13T was made up predominantly of iso- and anteiso-branched fatty acids. Genetic analyses demonstrated that strain T13T is closely related to Streptomyces gramineus JR-43T (98.29 % 16S rRNA gene sequence similarity), S. graminisoli JR-19T (97.99 %), S. rhizophilus JR-41T (97.86 %), S. longwoodensis LMG 20096T (97.84 %), S. graminifolii JL-22T (97.79 %) and S. yaanensis Z4T (97.56 %), and DNA–DNA hybridization yielded relatedness values of 35.27–43.42 % when T13T was compared to related strains. The results of morphological, chemotaxonomic, phylogenetic and phenotypic analyses confirm that this strain represents a novel species of the genus Streptomyces, for which the name Streptomyces olivicoloratus sp. nov. is proposed. The type strain is T13T ( = KEMB 9005-210T = KACC 18227T = NBRC 110901T).

An actinomycete, strain RI109-Li102T, was isolated from a lichen sample obtained from Rishiri Island in Japan. Cells of strain RI109-Li102T were Gram-positive, aerobic and non-motile and formed bud-like spore chains. The isolate grew with 0–3 % (w/v) NaCl, at pH 5–9 and at 10–30 °C (optimum 30 °C). The whole-cell hydrolysate contained meso-diaminopimelic acid, arabinose and galactose. The predominant menaquinone was MK-8(H4) and the diagnostic phospholipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylinositol and diphosphatidylglycerol. The major cellular fatty acids were iso-C16 : 0 and iso-C16 : 1 H. Comparative 16S rRNA gene sequence analysis revealed that strain RI109-Li102T was most closely related to Actinomycetospora corticicola 014-5T (99.0 % rRNA gene sequence similarity) and Actinomycetospora chiangmaiensis YIM 0006T (98.4 %). However, DNA–DNA hybridization assays, as well as physiological and biochemical analyses, showed that strain RI109-Li102T could be differentiated from its closest phylogenetic relatives. It is proposed that strain RI109-Li102T ( = NBRC 106356T  = KCTC 19782T) be classified as the type strain of a novel species, with the name Actinomycetospora rishiriensis sp. nov.

A bacterial strain, PY2T, capable of oxidizing carbon monoxide, was isolated from a soil sample collected from a roadside at Yonsei University, Seoul, Korea. On the basis of 16S rRNA gene sequence analysis, strain PY2T was shown to belong to the genus Terrabacter and was most closely related to Terrabacter lapilli LR-26T (99.1 % similarity). Strain PY2T was characterized chemotaxonomically as having iso-C15 : 0 as the predominant fatty acid, MK-8(H4) as the major menaquinone, ll-diaminopimelic acid as the diagnostic diamino acid of the cell wall, as possessing a polar lipid profile that included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and unknown amino-containing phosphoglycolipids, and having a DNA G+C content of 75.6 mol%. DNA–DNA relatedness values between strain PY2T and the type strains of T. lapilli, Terrabacter tumescens, Terrabacter terrae and Terrabacter aerolatus were 20.0 %, 22.9 %, 35.9 % and 64.5 %, respectively. Based on the combined evidence from the phylogenetic analyses, chemotaxonomic data and DNA–DNA hybridization experiments, it is proposed that strain PY2T represents a novel species for which the name Terrabacter carboxydivorans sp. nov. is proposed. The type strain is PY2T (=KCCM 42922T=JCM 16259T).

Strain ATCC 31180T was isolated from soil collected in Hyde Park, Massachusetts (USA), and found to produce the polyether antibiotic lasalocid. The name ‘Streptomyces lasaliensis’ has been in common use since 1974, without a recognized taxonomic description. The most closely related type cultures determined by rRNA gene sequence similarity were Streptomyces longwoodensis DSM 41677T (100 %) and Streptomyces galbus DSM 40089T (100 %). OrthoANI values with S. longwoodensis and S. galbus were 95.50 and 94.41 %, respectively. Chemotaxonomic characteristics supported inclusion within the genus Streptomyces . The cell wall peptidoglycan contained ll-diaminopimelic acid, and the major whole-cell sugars were glucose and ribose. Polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol, phosphatidylglycerol, one unidentified lipid and one unidentified glycolipid. The major menaquinones detected were MK9(H4), MK9(H6) and MK9(H8). The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0, iso-C15 : 0 and anteiso-C17 : 1. Its DNA had a G+C content of 72.6 %. Differentiation of ATCC 31180T from the closely related species was evident from digital DNA–DNA hybridization values of 61.80 and 56.90 % for S. longwoodensis and S. galbus respectively. Significant differences were seen in the polyphasic phenotypic analyses. ATCC 31180T produced lasalocid, grew from 10 to 45 °C, pH4-8 and in the presence of 0–10 % NaCl, 0.01 % NaN3 and 1 % phenol. Melanin was produced; H2S and indole were not. Nitrate was not reduced. Spore chains were retinaculum-apertum and spore surfaces were smooth. Spore colour, mycelia colour and soluble pigment production were medium-dependent. The proposed name is Streptomyces lasalocidi sp. nov.; the type strain being ATCC 31180T (=NRRL 3382T=DSM 46487T).

A bacterial strain designated 11N27T was isolated from an agricultural soil sample. Cells of this strain were Gram-reaction-variable, facultatively anaerobic, endospore-forming, white-pigmented, peritrichously flagellated and hydrolysed xanthine. The major fatty acids of strain 11N27T were anteiso-C15 : 0, iso-C16 : 0 and C16 : 0. The polar lipid profile contained phosphatidylethanolamine, two unknown phospholipids, two unknown aminolipids, one unknown aminophospholipid and two unknown polar lipids. The G+C content of the genomic DNA of strain 11N27T was 50.3 mol%. MK-7 was the predominant respiratory quinone. meso-Diaminopimelic acid was the diagnostic diamino acid in the peptidoglycan. 16S rRNA gene sequence analysis showed that strain 11N27T was phylogenetically related to Paenibacillus mendelii C/2T (96.2  % sequence similarity) and Paenibacillus sepulcri CMM 7311T (96.0  %). The genotypic and phenotypic data showed that strain 11N27T could be distinguished from phylogenetically related species and that this strain represents a novel species of the genus Paenibacillus. The name Paenibacillus xanthinilyticus sp. nov. is proposed with the type strain 11N27T( = KACC 17935T = NBRC 109108T).

A novel aerobic actinomycete, designated HA11110T, was isolated from a mangrove soil sample collected in Haikou, China. It formed white aerial mycelium and pale yellow substrate mycelium on Gause's synthetic agar no. 1. Scanning electron microscopy revealed that cells of HA11110T produced straight to spiral spore chains with spiny spores. Chemotaxonomic tests showed that the cell wall contained ll-diaminopimelic acid and the major fatty acids were iso-C16 : 0, anteiso-C15 : 0 and iso-C14 : 0.16S rRNA gene sequence similarity showed that strain HA11110T belonged to the genus Streptomyces, most closely related to Streptomyces fenghuangensis GIMN4.003T (99.1 %), Streptomyces nanhaiensis SCSIO 01248T (98.8 %) and Streptomyces radiopugnans R97T (98.8 %). However, DNA–DNA hybridization studies of strain HA11110T with these three closest relatives showed relatedness values of 58.4, 49.7 and 47.2 %, respectively. On the basis of phenotypic and genotypic data, strain HA11110T represents a novel species of the genus Streptomyces, for which the name Streptomyces mangrovi sp. nov. is proposed. The type strain is HA11110T ( = CGMCC 4.7117T = DSM 42113T).
