A Gram-positive bacterium, designated strain AG019T, was isolated by micromanipulation from aerobic granules obtained from a laboratory-scale sequencing batch reactor. This isolate grew axenically as cocci clustered predominantly in tetrads, and was morphologically similar to the dominant organisms observed in the biomass. The morphology also resembled that of the tetrad-forming organisms commonly seen in activated sludge samples. Strain AG019T was found to be an oxidase-negative, catalase-positive, non-motile aerobe that does not reduce nitrate and grows at temperatures between 15 and 40 °C, with an optimum at 37 °C. The pH range for growth was 5·0–9·0, with an optimum at pH 7·5. Strain AG019T contained a peptidoglycan with directly cross-linked meso-diaminopimelic acid (type A1γ) and lacked mycolic acids. The G+C content of the DNA was 75 mol%. Menaquinone MK-8(H2) was the major isoprenoid quinone. The bacterium stained positively for intracellular polyphosphate granules but not for poly-β-hydroxyalkanoates. It produced capsular material and showed autoaggregation ability. Phenotypic and 16S rRNA gene analyses showed that the bacterium differed sufficiently from its closest phylogenetic relatives, namely members of the suborder Frankineae, which includes the genera Geodermatophilus, Blastococcus, Frankia, Sporichthya, Acidothermus and Microsphaera, that it is proposed that it be placed in a novel genus, Quadrisphaera, as Quadrisphaera granulorum gen. nov., sp. nov. The type strain is AG019T (=ATCC BAA-1104T=DSM 44889T).

A Gram-positive bacterium, designated strain PG-02T, was isolated by serial dilution from aerobic granules obtained from a laboratory-scale sequencing batch reactor for bioremediation of phenolic wastewater. Strain PG-02T grew axenically as cocci and is an oxidase-negative and catalase-positive, non-motile facultative anaerobe. It does not reduce nitrate and grows between 15 and 37 °C, with an optimum temperature of 30 °C. The pH range for growth is between 5.0 and 8.5, with an optimum pH of 7.0. Strain PG-02T contains type A3γ peptidoglycan (ll-A2pm←Gly with alanine at position 1 of the peptide subunit). The G+C content of the DNA is 69 mol%. Menaquinone MK-9(H4) was the major isoprenoid quinone. The polar lipids included diphosphatidylglycerol and phosphatidylglycerol, while 13-methyltetradecanoic acid (i-C15 : 0) and 1,1-dimethoxy-iso-pentadecane (i-C15 : 0 DMA) were the major components in whole-cell methanolysates. PG-02T stained positively for intracellular polyphosphate granules but not poly-β-hydroxyalkanoates. It produces capsular material and possesses an autoaggregation capability. Phenotypic and 16S rRNA gene sequence analyses showed that PG-02T differed from its closest phylogenetic relatives, namely members of the suborder Propionibacterineae, which includes the genera Tessaracoccus, Microlunatus, Luteococcus, Micropruina, Propionibacterium, Propioniferax, Nocardioides, Friedmanniella and Aeromicrobium, and that it should be placed in a new genus and species as Granulicoccus phenolivorans gen. nov., sp. nov. The type strain of Granulicoccus phenolivorans is PG-02T (=ATCC BAA-1292T=DSM 17626T).

An aerobic, Gram-positive, non-motile, non-spore-forming, rod–coccus-shaped bacterium, strain 5317S-21T, was isolated from an air sample from Suwon city, Republic of Korea. The isolate was able to grow within a pH range of 5.0–9.0 and a temperature range of 5–35 °C and it tolerated up to 2 % (w/v) NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid as diagnostic diamino acid. The predominant isoprenoid quinone was MK-8(H4). The major polar lipids were phosphatidylinositol, phosphatidylethanolamine and diphosphatidylglycerol; phosphatidylglycerol and several unknown phospholipids were also detected. Mycolic acids were absent. The only whole-cell sugar was glucose. The major cellular fatty acids were iso-C16 : 0, C17 : 1 ω8c and iso-C15 : 0. 16S rRNA gene sequence analysis indicated that strain 5317S-21T was related phylogenetically to members of the genus Knoellia, with 97.4 % sequence similarity to the type strains of Knoellia sinensis and Knoellia subterranea. The G+C content of the genomic DNA of strain 5317S-21T was 73 mol%. Levels of DNA–DNA relatedness between strain 5317S-21T and the type strains of Knoellia sinensis and Knoellia subterranea were 37 and 41 %, respectively. It was concluded that strain 5317S-21T represents a novel species of the genus Knoellia, for which the name Knoellia aerolata sp. nov. is proposed. The type strain is 5317S-21T (=KACC 20583T =DSM 18566T).

Three moderately halophilic, spore-forming strains, designated BH030062T, BH030049 and BH030080, were isolated from a solar saltern in Korea. Phylogenetic analyses and comparative 16S rRNA gene sequence studies revealed that the isolates represent a novel distinct monophyletic lineage within the phyletic group classically defined as the genus Bacillus and are most closely related to members of the genera Gracilibacillus (93·7–95·1 % similarity), Virgibacillus (93·5–94·8 %), Halobacillus (94·8–95·9 %), Filobacillus (94·4–94·8 %) and Lentibacillus (93·3–93·7 %). Strain BH030062T was strictly aerobic, rod-shaped, Gram-positive and motile by means of peritrichous flagella. It grew in the presence of 1–15 % (w/v) NaCl and at temperatures of 15–45 °C. The cell wall peptidoglycan contained A1γ-meso-diaminopimelic acid as the diagnostic diamino acid. The predominant cellular fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0. DNA G+C content was about 41 mol% and the major isoprenoid quinone was MK-7. On the basis of their physiological and molecular properties, the isolates represent a new genus, Pontibacillus gen. nov., and novel species, Pontibacillus chungwhensis sp. nov. The type strain is BH030062T (=KCTC 3890T=DSM 16287T).

A moderately halophilic and alkalitolerant bacterium, designated strain HN30T, was isolated from garden soil in Japan. Cells of strain HN30T were motile, endospore-forming, aerobic, rod-shaped and Gram-positive, and contained A1γ meso-diaminopimelic acid-type murein. Growth occurred in 7–23 % (w/v) NaCl (optimum, 10–15 %, w/v), at pH 6.5–10.0 (optimum, pH 8.0–8.5) and at 20–40 °C (optimum, 30 °C). The isoprenoid quinone was menaquinone-7. The polar lipids were phosphatidylglycerol and diphosphatidylglycerol. The major cellular fatty acids were anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and C16 : 0. The DNA G+C content of strain HN30T was 47 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain HN30T was most closely related to Geomicrobium halophilum BH1T (93 % sequence similarity). 16S rRNA gene sequence similarities with other recognized species were less than 89 %. Phylogenetic and phenotypic characteristics indicated that strain HN30T represents a novel species in a new genus, for which the name Natribacillus halophilus gen. nov., sp. nov. is proposed; the type strain is HN30T ( = JCM 15649T = DSM 21771T).

A novel actinobacterium, strain A8036T, isolated from soil, was investigated by using a polyphasic taxonomic approach. The organism formed extensively branched substrate hyphae that generated spiral chains of spores with irregular surfaces. The cell wall contained meso-diaminopimelic acid (type III) and cell-wall sugars were glucose, madurose, mannose and ribose. The predominant menaquinones were MK-9(H6) and MK-9(H4). The phospholipids were diphosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannosides. The major cellular fatty acids were iso-C16 : 0, C17 : 1 cis9, C16 : 0, C15 : 0 and 10-methyl C17 : 0. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of strain A8036T were Actinomadura meyerae DSM 44715T (99.23 % similarity), Actinomadura bangladeshensis DSM 45347T (98.9 %) and Actinomadura chokoriensis DSM 45346T (98.3 %). However, DNA–DNA relatedness and phenotypic data demonstrated that strain A8036T could be clearly distinguished from the type strains of all closely related Actinomadura species. Strain A8036T is therefore considered to represent a novel species of the genus Actinomadura , for which the name Actinomadura geliboluensis sp. nov. is proposed. The type strain is A8036T ( = DSM 45508T = KCTC 19868T).

A novel Gram-staining-positive, rod-shaped, motile, strictly aerobic, endospore-forming bacterium, designated WCC 4585T, was isolated from a pharmaceutical production line. The organism grew optimally at 30 °C, at pH 8 and in the presence of 0.5 % (w/v) NaCl. Oval endospores were formed subterminally and terminally in swollen sporangia. The cell-wall diamino acid was meso-diaminopimelic acid (type A1γ) and the genomic DNA G+C content was 38.7 mol%. The major menaquinone was MK-7. The cellular fatty acid profile contained major amounts of iso-C15 : 0, anteiso-C15 : 0 and anteiso-C17 : 0, and the cellular phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and aminophospholipid. The isolate was most closely related to Bacillus oceanisediminis H2T, Bacillus infantis SMC 4352-1T, Bacillus firmus NCIMB 9366T, Bacillus circulans ATCC 4513T and Bacillus horneckiae DSM 23495T with which it shared less than 98.0 % 16S rRNA gene sequence similarity. DNA–DNA relatedness values between strain WCC 4585T and five type strains of related species were ≤27 % and sequence similarity values based on groEL sequences were ≤88.7 %. On the basis of the characteristics presented, strain WCC 4585T is proposed to represent a novel species, Bacillus gottheilii sp. nov. The type strain is WCC 4585T( = DSM 23668T = CCUG 59876T = LMG 25856T).

A Gram-positive, coccoid, non-endospore-forming actinobacterium (strain 12-Be-011T) was isolated from indoor wall material. Based on 16S rRNA gene sequence comparisons, strain 12-Be-011T was clearly shown to belong to the genus Microlunatus and was most closely related to Microlunatus panaciterrae Gsoil 954T (95.7 %), Microlunatus soli CC-12602T (94.9 %), Microlunatus ginsengisoli Gsoil 633T (94.8 %), Microlunatus aurantiacus YIM 45721T (95.5 %) and Microlunatus phosphovorus DSM 10555T (94.7 %). The cell-wall peptidoglycan contained ll-diaminopimelic acid as the diagnostic diamino acid. Mycolic acids were absent. The major menaquinone was MK-9(H4). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two unknown phospholipids and one unknown glycolipid. The major fatty acids of iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0 supported the affiliation of strain 12-Be-011T to the genus Microlunatus. Physiological and biochemical test results allowed a clear phenotypic differentiation of strain 12-Be-011T from all other species of the genus Microlunatus. Hence, strain 12-Be-011T can be regarded as a representative of a novel species, for which the name Microlunatus parietis sp. nov. is proposed, with the type strain 12-Be-011T (=DSM 22083T=CCM 7636T).

A novel actinomycete strain, designed MW4-36T, was isolated from tropical forest soil in Nakhon Sawan Province, Thailand. Morphological and chemotaxonomic characteristics of this strain clearly demonstrated that it belongs to the genus Dactylosporangium . The strain formed finger-shaped sporangia on short sporangiophores that emerged directly from substrate hyphae. The cell-wall peptidoglycan contained glutamic acid, glycine, alanine and meso-diaminopimelic acid including 3-hydroxy-meso-diaminopimelic acid; arabinose, glucose, rhamnose, ribose and xylose were found as whole-cell sugars. The diagnostic phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylinositol; no phosphatidylcholine was found. The predominant menaquinones were MK-9(H8) and MK-9(H6). Mycolic acids were not detected. The predominant cellular fatty acids were iso-C15 : 0, iso-C16 : 0, anteiso-C15 : 0 and anteiso-C17 : 0. The G+C content of the genomic DNA was 72.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequences also indicated that the strain should be classified in the genus Dactylosporangium and showed that the closest relative was Dactylosporangium maewongense JCM 15933T (99.4 % similarity). These taxonomic data revealed that strain MW4-36T could be readily distinguished from its phylogenetically closest relative. On the basis of these phenotypic and genotypic data, strain MW4-36T is considered to represent a novel species, for which the name Dactylosporangium siamense sp. nov. is proposed. The type strain is MW4-36T ( = BCC 34901T = NBRC 106093T).

Two actinomycete strains, JSM1-1T and JSM1-3, were isolated from sea sand collected in Thailand. Their taxonomic position was determined using a polyphasic approach. The chemotaxonomic characteristics of these strains coincided with those of the genus Micromonospora, i.e. the presence of meso-diaminopimelic acid and N-glycolyl muramic acid in the peptidoglycan, whole cell sugar pattern D, phospholipids type II, and cellular fatty acid type 3b. Phylogenetic analysis of 16S rRNA gene sequences revealed a close relationship between strains JSM1-1T and JSM1-3 (99.8 %), and between JSM1-1T and Micromonospora aurantiaca JCM 10878T (99.3 %), Micromonospora chalcea JCM 3031T (99.0 %), and Micromonospora coxensis JCM 13248 T (99.0 %). However, strains JSM1-1T and JSM1-3 could be clearly distinguished from these type strains by a low DNA–DNA relatedness and by phenotypic differences. On the basis of the data presented, a new species, Micromonospora marina sp. nov., is proposed. The type strain is JSM1-1T (=JCM 12870T =PCU 269T =TISTR 1566T).
