A Gram-positive, non-spore-forming bacterium (strain GW4-1778T) was isolated from soil of the Italian island of Stromboli. 16S rRNA gene sequence similarity studies showed that strain GW4-1778T is a member of the genus Nocardia, most closely related to Nocardia pseudobrasiliensis (GenBank accession no. DQ659914; 98.6 %), Nocardia nova (Z36930; 98.6 %), Nocardia niigatensis (AB092563; 98.4 %), Nocardia jiangxiensis (AY639902; 98.0 %), Nocardia uniformis (Z46752; 98.0 %) and Nocardia miyunensis (AY639901; 97.8 %). Strain GW4-1778T could be distinguished from any other established Nocardia species by sequence similarity values of less than 97.5 %. Strain GW4-1778T exhibited a quinone system with the predominant compound MK-8 (H4, ω-cycl) (99.5 %) and traces of MK-8 (H4), characteristic for the genus Nocardia. The polar lipid profile of strain GW4-1778T consisted of the predominant compound diphosphatidylglycerol, moderate amounts of phosphatidylethanolamine, phosphatidylinositol, two phosphatidylinositol mannosides, a unknown polar lipid and trace amounts of two unknown lipids and the major fatty acids were C15 : 0, C16 : 0, C17 : 1 ω8c and 10-methyl C17 : 0. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW4-1778T from related species with 16S rRNA gene similarities of >97.5 %. Therefore, strain GW4-1778T merits species status, for which the name Nocardia acidivorans sp. nov. is proposed, with the type strain GW4-1778T (=CCUG 53410T=CIP 109315T=DSM 45049T).

A Gram-stain-positive, coccoid, non-endospore-forming actinobacterium (Sj14aT) was isolated from the air of a duck barn on tryptone soy agar after filter sampling. On the basis of 16S rRNA gene sequence similarity studies, strain Sj14aT was shown to belong to the genus Dietzia and was most closely related to Dietzia schimae (98.7 %), Dietzia cercidiphylli (98.4 %) and Dietzia maris (98.6 %). The major menaquinone was MK-8 (H2). The polar lipid profile included the major components diphosphatidylglycerol, phosphatidylglycerol, an unknown polar lipid and two unknown glycolipids. Phosphatidylinositol and two phosphatidylinositol mannosides, as well as several other unknown lipids, were also detected. The polyamine pattern contained the major compounds spermine and spermidine. The fatty acid profile, containing C16 : 0, C17 : 0, C18 : 1 ω9c and 10-methyl C18 : 0 as major fatty acids, supported the affiliation of strain Sj14aT to the genus Dietzia. The results of physiological and biochemical tests and DNA–DNA hybridizations allowed a clear phenotypic differentiation of strain Sj14aT from the most closely related species of the genus Dietzia. Strain Sj14aT represents a novel species, for which the name Dietzia aerolata sp. nov. is proposed, with the type strain Sj14aT (=DSM 45334T =CCM 7659T).

A novel Gram-stain-positive actinobacterium, designated strain SCSIO 11529T, was isolated from tissues of the stony coral Galaxea fascicularis, and characterized by using a polyphasic approach. The temperature range for growth was 22–50 °C (optimum 28–45 °C), the pH range for growth was 6.0–8.0 (optimum pH 7.0), and the NaCl concentration range for growth was 0–7 % (w/v) NaCl. The polar lipid profile contained diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine and an unknown polar lipid. The predominant menaquinone was MK-9(H4). The major fatty acids (>10 %) were iso-C16 : 0, iso-C17 : 1ω6c, iso-C16 : 1 H and C16 : 1ω7c/iso-C15 : 0 2-OH. The DNA G+C content of strain SCSIO 11529T was 70.2 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain SCSIO 11529T belongs to the genus Prauserella , with the closest neighbours being Prauserella marina MS498T (97.0 % 16S rRNA gene sequence similarity), Prauserella rugosa DSM 43194T (96.4 %) and Prauserella flava YIM 90630T (95.9 %). Based on the evidence of the present study, strain SCSIO 11529T is considered to represent a novel species of the genus Prauserella , for which the name Prauserella coralliicola sp. nov. is proposed. The type strain is SCSIO 11529T ( = DSM 45821T = NBRC 109418T).

A Gram-positive, aerobic, long-rod-shaped, non-spore-forming bacterium (strain PPLBT) was isolated from soil mixed with Iberian pig hair. This actinomycete showed keratinase activity in vitro when chicken feathers were added to the culture medium. Strain PPLBT was oxidase-negative and catalase-positive and produced lipase and esterase lipase. This actinomycete grew at 40 °C on nutrient agar and in the same medium containing 5 % (w/v) NaCl. Growth was observed with many different carbohydrates as the sole carbon source. On the basis of 16S rRNA gene sequence similarity, strain PPLBT was shown to belong to the genus Terrabacter of the family Intrasporangiaceae. Strain PPLBT showed 98·8 % 16S rRNA gene sequence similarity to Terrabacter tumescens. Chemotaxonomic data, such as the main ubiquinone (MK-8), the main polar lipids (phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol) and the main fatty acids (i-C15 : 0, ai-C15 : 0, i-C16 : 0 and ai-C17 : 0) supported the affiliation of strain PPLBT to the genus Terrabacter. The G+C content of the DNA was 71 mol%. The results of DNA–DNA hybridization (36·6 % relatedness between Terrabacter tumescens and strain PPLBT) and physiological and biochemical tests suggested that strain PPLBT belongs to a novel species of the genus Terrabacter, for which the name Terrabacter terrae sp. nov. is proposed. The type strain is PPLBT (=CECT 3379T=LMG 22921T).

A Gram-positive bacterium, strain GW8-1761T, was isolated from soil close to the Marmore waterfalls, Terni, Italy. 16S rRNA gene sequence similarity studies showed that strain GW8-1761T belonged to the genus Actinoplanes, being most closely related to Actinoplanes italicus JCM 3165T (98.9 %), A. rectilineatus IFO 13941T (98.5 %), A. palleronii JCM 7626T (97.8 %), A. utahensis IFO 13244T (97.6 %) and A. cyaneus DSM 46137T (97.6 %). Strain GW8-1761T could be distinguished from any other Actinoplanes species with validly published names by 16S rRNA gene sequence similarity values of less than 97.5 %. Chemotaxonomic data [major menaquinone MK-9(H4); major polar lipids diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol, with phosphatidylcholine and aminoglycolipids absent; major fatty acids C15 : 0, C16 : 0, C16 : 0 iso, C17 : 1 ω8c and summed feature 3 (C16 : 1 ω7c and/or C15 : 0 iso 2-OH)] supported the affiliation of strain GW8-1761T to the genus Actinoplanes. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW8-1761T from the most closely related species. Strain GW8-1761T therefore merits species status, and we propose the name Actinoplanes couchii sp. nov., with the type strain GW8-1761T (=DSM 45050T=CIP 109316T).

A Gram-stain-positive actinobacterium, designated strain YIM 93316T, was isolated from a salt lake in Xinjiang Province, north-west China, and was subjected to a polyphasic taxonomic study. The isolate grew at 10–45 °C, at pH 6–9 and in the presence of 1–15 % (w/v) NaCl, but no growth was observed in the absence of NaCl. The cell-wall diamino acid contained alanine, glutamine and lysine with peptidoglycan type A4α. Polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannosides, an unknown glycolipid and an unknown phospholipid. The predominant menaquinone was MK-8(H4). The major fatty acids were anteiso-C15 : 0 and anteiso-C15 : 1. The DNA G+C content of strain YIM 93316T was 70.1 mol%. Chemotaxonomic properties supported the affiliation of strain YIM 93316T to the genus Georgenia, and this was supported by phylogenetic analysis based on 16S rRNA gene sequences. Levels of 16S rRNA gene sequence similarity between strain YIM 93316T and Georgenia thermotolerans TT02-04T, Georgenia ruanii YIM 004T and Georgenia muralis 1A-CT were 96.6, 96.5 and 96.3 %, respectively. Data from fatty acid, physiological and biochemical tests allowed the clear phenotypic differentiation of strain YIM 93316T from recognized members of the genus Georgenia. On the basis of evidence from the present polyphasic study, strain YIM 93316T is considered to represent a novel species of the genus Georgenia, for which the name Georgenia halophila sp. nov. is proposed. The type strain is YIM 93316T (=DSM 21365T =CCTCC AB 208144T).

Biochemical and molecular genetic studies were performed on three novel Gram-stain-negative, catalase- and oxidase-positive, bacilli-shaped organisms isolated from the tonsils of two pigs and one wild boar. The micro-organism was identified as a species of the genus Pelistega based on its cellular morphological and biochemical tests. The closest phylogenetic relative of the novel bacilli was Pelistega indica HM-7T (98.2 % 16S rRNA gene sequence similarity to the type strain). groEL and gyrB sequence analysis showed interspecies divergence from the closest 16S rRNA gene phylogenetic relative, P. indica of 87.0.% and 69 %, respectively. The polyamine pattern contains predominantly putrescine and 2-hydroxyputrescine. The major quinone is ubiquinone Q-8 and in the polar lipid profile, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid and an unidentified lipid are predominant. The novel bacterial isolate can be distinguished from P. indica by several biochemical characteristics, such as the production of l-pyrrolydonil arylamidase but not gamma-glutamyl-transferase, and the utilization of different carbon sources. Based on both phenotypic and phylogenetic findings, the novel bacterium is classified as representing a novel species of the genus Pelistega, for which the name Pelistega suis sp. nov. is proposed. The type strain is 3340-03T ( = CECT 8400T = CCUG 64465T).

A bacterial strain, designated KTW-16T, was isolated from the reef-building coral Stylophora pistillata, collected from southern Taiwan. Strain KTW-16T was a Gram-negative, facultatively anaerobic, pale-yellow, non-motile short rod. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain KTW-16T belonged to the genus Paracoccus in the Alphaproteobacteria and exhibited 93.7–96.9 % 16S rRNA gene sequence similarity with type strains of species of the genus Paracoccus (96.9 % with Paracoccus alcaliphilus JCM 7364T). Strain KTW-16T grew at 15–40 °C (optimum 35 °C), at pH 6.0–10.0 (optimum pH 8.0) and with 0–9 % NaCl (optimum 5 %). The predominant cellular fatty acids were C18 : 1ω7c, C19 : 0 cyclo ω8c and C18 : 0. The major respiratory quinone was Q-10 and the DNA G+C content was 69.1 mol%. The polar lipid profile consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylcholine and several unknown polar lipids. The physiological and biochemical tests allowed clear phenotypic differentiation of the isolate from the type strains of already described Paracoccus species. It is evident from the genotypic, phenotypic and chemotaxonomic analysis that strain KTW-16T should be classified in a novel species of the genus Paracoccus, for which the name Paracoccus stylophorae sp. nov. is proposed. The type strain is KTW-16T ( = LMG 25392T  = BCRC 80106T).

A Gram-staining-positive coccus, designated CC-SPL15-2T, was isolated from the rhizosphere of Sesuvium portulacastrum. By 16S rRNA gene sequence analysis, it was shown that strain CC-SPL15-2T belonged to the genus Salinicoccus. The isolate was most closely related to Salinicoccus hispanicus DSM 5352T (98.3 % 16S rRNA gene sequence similarity) and Salinicoccus roseus DSM 5351T (96.7 %); similarities to all other members of the genus Salinicoccus were <96.5 %. In accordance with characteristics of the genus Salinicoccus, the quinone system was mainly composed of menaquinone MK-6. The polar lipid profile exhibited the major components diphosphatidylglycerol, phosphatidylglycerol and an unidentified glycolipid. In the polyamine pattern, spermidine was the predominant compound. The fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0, which supported the affiliation of strain CC-SPL15-2T to the genus Salinicoccus. DNA–DNA relatedness between strain CC-SPL15-2T and S. hispanicus CCUG 43288T was 42 and 32 % (reciprocal analysis). From these data as well as from physiological and biochemical tests, a clear differentiation of strain CC-SPL15-2T from S. hispanicus and other members of the genus Salinicoccus was possible. We propose that strain CC-SPL15-2T be assigned to a novel species, with the name Salinicoccus sesuvii sp. nov. The type strain is CC-SPL15-2T ( = DSM 23267T  = CCM 7756T).

A Gram-positive, aerobic or facultatively anaerobic, rod-shaped, spore-forming bacterium, strain Gsoil 1138T, was isolated from soil of a ginseng field in Pocheon Province, South Korea, and was characterized in order to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, strain Gsoil 1138T was shown to belong to the family Paenibacillaceae and was most closely related to the type strains of Paenibacillus chondroitinus (98.2 % similarity) and Paenibacillus alginolyticus (96.5 %). Levels of 16S rRNA gene sequence similarity between strain Gsoil 1138T and the type strains of other recognized species of the genus Paenibacillus were below 96.5 %. The G+C content of the genomic DNA of strain Gsoil 1138T was 52.1±0.2 mol% (mean±sd of three determinations). Phenotypic and chemotaxonomic data (MK-7 as the major menaquinone and anteiso-C15 : 0 and iso-C16 : 0 as the predominant fatty acids) supported the affiliation of strain Gsoil 1138T to the genus Paenibacillus. The results of DNA–DNA hybridization experiments and physiological and biochemical tests allowed strain Gsoil 1138T to be distinguished genotypically and phenotypically from recognized species of the genus Paenibacillus. Strain Gsoil 1138T is therefore considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus pocheonensis sp. nov. is proposed. The type strain is Gsoil 1138T (=KCTC 13941T=LMG 23404T).

A bacterial strain, designated P15T, was isolated from the soil of an open hexachlorocyclohexane dumpsite. Comparative sequence analysis showed that strain P15T displayed high 16S rRNA gene sequence similarities (94.4–97.2 %) with members of the genus Pseudoxanthomonas. The isolate was most closely related to Pseudoxanthomonas mexicana AMX 26BT (97.2 % 16S rRNA gene sequence similarity) and Pseudoxanthomonas japonensis 12-3T (97.2 %). DNA–DNA relatedness studies showed unambiguously that strain P15T represented a novel species that was separate from P. mexicana DSM 17121T (7.7 %) and P. japonensis DSM 17109T (9.4 %). The predominant cellular fatty acids of strain P15T were iso-C16 : 0 (21.4 %), iso-C15 : 0 (16.1 %), summed feature 9 (comprising iso-C17 : 1ω9c and/or 10-methyl C16 : 0; 14.9 %), iso-C11 : 0 3-OH (8.3 %) and iso-C14 : 0 (7.0 %). The polar lipid profile of strain P15T showed the presence of large amounts of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol in addition to unknown glycolipids, phospholipids and an amino-group-containing polar lipid. Ubiquinone 8 was found as the major quinone. The polyamine profile showed the presence of spermidine. The DNA G+C content was 62.9±2 mol%. Strain P15T is described as representing a new member of the genus Pseudoxanthomonas, for which the name Pseudoxanthomonas indica sp. nov. is proposed. The type strain is P15T ( = MTCC 8596T = CCM 7430T).
