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-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).

Two strains (Gsoil 492T and Gsoil 643T) isolated in Pocheon Province, South Korea, from soil used for ginseng cultivation were characterized using a polyphasic approach. Both isolates comprised Gram-negative, aerobic, non-motile, rod-shaped bacteria. They had similar chemotaxonomic characteristics, e.g. containing MK-7 as the major quinone, having a DNA G+C content in the range 42.5–43.3 mol% and possessing iso-C15 : 0 and iso-C17 : 0 3-OH as the major fatty acids. A phylogenetic analysis based on 16S rRNA gene sequences indicated that the two isolates formed a tight cluster with several uncultured bacterial clones and with the established genera Terrimonas, Niastella and Chitinophaga in the phylum Bacteroidetes but were clearly separate from these genera. The levels of 16S rRNA gene sequence similarity between the isolates and type strains of related genera ranged from 87.5 to 92.4 %. Furthermore, the results of physiological and biochemical tests allowed phenotypic differentiation of the isolates from phylogenetically closely related species with validly published names. The level of 16S rRNA gene sequence similarity between the two strains was 99.5 %, whereas the DNA–DNA relatedness value was 44 %, indicating that they represent separate species. On the basis of the polyphasic evidence, a novel genus, Flavisolibacter gen. nov., and two novel species, Flavisolibacter ginsengiterrae sp. nov. (type strain Gsoil 492T=KCTC 12656T=DSM 18136T) and Flavisolibacter ginsengisoli sp. nov. (type strain Gsoil 643T=KCTC 12657T=DSM 18119T), are proposed. Flavisolibacter ginsengiterrae is the type species of the genus.

A Gram-reaction-negative, chemo-organotrophic, non-motile, non-spore-forming, rod-shaped bacterium (strain Gsoil 080T) was isolated from soil collected in a ginseng field in Pocheon Province, South Korea, and was investigated by using a polyphasic taxonomic approach. Comparative 16S rRNA gene sequence analysis showed that strain Gsoil 080T was related most closely to Inquilinus limosus strains AU0476T and AU1979 (98.9 % similarity to both). Strain Gsoil 080T shared ≤91.3 % 16S rRNA gene sequence similarity with the type strains of other recognized species examined. The genus Inquilinus belongs to the family Rhodospirillaceae in the order Rhodospirillales, class Alphaproteobacteria. The predominant ubiquinone was Q-10 and the major fatty acids were summed feature 7 (C18 : 1 ω9c/ω12t/ω7c) and C19 : 0 cyclo ω8c. The G+C content of the genomic DNA of strain Gsoil 080T was 69.9 mol%. The level of DNA–DNA relatedness between strain Gsoil 080T and I. limosus LMG 20952T was 12 %. The results of genotypic analyses in combination with chemotaxonomic and physiological data demonstrated that strain Gsoil 080T represents a novel species of the genus Inquilinus, for which the name Inquilinus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 080T (=KCTC 12574T =LMG 23638T).

Biochemical and molecular genetic studies were performed on an unknown Gram-stain-positive, catalase-negative, coccus-shaped organism isolated from clinical samples of a Pyrenean chamois. The micro-organism was identified as a streptococcal species based on its cellular morphological and biochemical tests. 16S rRNA gene sequence comparison studies confirmed its identification as a member of the genus Streptococcus, but the organism did not correspond to any species of this genus. The nearest phylogenetic relative of the unknown coccus from chamois was Streptococcus ovis (95.9 % 16S rRNA gene sequence similarity). The rpoB and sodA sequence analysis showed sequence similarity values of less than 85.7 % and 83.0 %, respectively, with the currently recognized species of the genus Streptococcus. The novel bacterial isolate was distinguished from S. ovis and other species of the genus Streptococcus using biochemical tests. Based on both phenotypic and phylogenetic findings, it is proposed that the unknown bacterium be classified as a novel species of the genus Streptococcus, Streptococcus rupicaprae sp. nov., with the type strain 2777-2-07T ( = CECT 7718T  = CCUG 59652T).

A novel aerobic, chemo-organoheterotrophic bacterium, strain Ac_26_B10T, was isolated from a semiarid savannah soil collected in northern Namibia (Mashare, Kavango region). Based on analysis of its nearly full-length 16S rRNA gene sequence, the isolate belongs to the genus Terriglobus (family Acidobacteriaceae, order Acidobacteriales, class Acidobacteria) and shares 98.3 and 96.9 % 16S rRNA gene sequence similarity with its closest relatives, Terriglobus tenax DRP 35T and T. aquaticus O3SUJ4T. Cells were Gram-negative, coccoid to rod-shaped, non-motile and divided by binary fission. Strain Ac_26_B10T showed weak catalase activity and, in contrast to the other described species of the genus Terriglobus, was oxidase-positive. Compared with the already established species of the genus Terriglobus, the novel strain used a larger range of sugars and sugar alcohols for growth, lacked α-mannosidase activity and exhibited a higher temperature optimum of growth. DNA–DNA hybridization studies with its closest phylogenetic relative, T. tenax DSM 28898T, confirmed that strain Ac_26_B10T represents a distinct genomospecies. Its most abundant fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and C16 : 0. Dominant polar lipids were phosphatidylethanolamine and diphosphatidylglycerol. The predominant menaquinone was MK-8; minor amounts of MK-7 and MK-8(H2) were also recorded. The G+C content of the genomic DNA was 58.5 mol%. On the basis of our polyphasic analysis, Ac_26_B10T represents a novel species of the genus Terriglobus, for which the name Terriglobus albidus sp. nov. is proposed. The type strain is Ac_26_B10T ( = DSM 26559T = LMG 27984T).

A novel Ferrimonas species is described on the basis of phenotypic, chemotaxonomic and phylogenetic studies. Four halophilic organisms were isolated from marine sand and marine macroalgae samples by using high-pH marine agar 2216. An analysis of the nearly complete 16S rRNA gene sequences of these new isolates indicated that they were phylogenetically close (16S rRNA gene sequence similarity >99·5 %, gyrB gene sequence similarity >97·8 %), and were most closely related to Ferrimonas balearica (16S rRNA gene sequence similarity 97·1–97·3 %, gyrB gene sequence similarity 84·4–85·0 %). Chemotaxonomic data (major menaquinone MK7; major fatty acids C16 : 0 and C18 : 1 ω9c) supported the affiliation of the new isolates to the genus Ferrimonas. The results of physiological and biochemical tests allowed phenotypic differentiation of the isolates from F. balearica. It is therefore proposed that the new isolates represent a novel species with the name Ferrimonas marina sp. nov. and type strain A4D-4T (=MBIC06480T=DSM 16917T).

A Gram-positive, non-spore-forming bacterium (GW39-1573T) was isolated from soil of the Spanish island of Tenerife. 16S rRNA gene sequence similarity studies showed that strain GW39-1573T belonged to the genus Nocardia and was most closely related to Nocardia brasiliensis (98·0 %), Nocardia beijingensis (97·3 %), Nocardia transvalensis (97·5 %), Nocardia asteroides (97·2 %) and Nocardia farcinica (97·0 %). Strain GW39-1573T could be distinguished from all other validly described Nocardia species by sequence similarity values of less than 97 %. Chemotaxonomic data [major menaquinone: MK-8(H4, ω-cycl); major polar lipids: diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and an unknown glycolipid and an unknown phospholipid; major fatty acids: C16 : 0, C18 : 1 ω9c and 10 methyl C16 : 0] and the presence of mycolic acids supported the affiliation of strain GW39-1573T to the genus Nocardia. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW39-1573T from those related species that showed 16S rRNA gene sequence similarity values of greater than 97 %. Strain GW39-1573T merits species status, and the name Nocardia tenerifensis is proposed with the type strain GW39-1573T (=DSM 44704T=CIP 107929T).

Seven isolates of an unidentified Gram-stain-positive, catalase-negative, coccus-shaped organism isolated from domestic and wild pigs were characterized by phenotypic and molecular-genetic methods. Based on cellular morphology and biochemical criteria, the isolates were tentatively assigned to the genus Streptococcus, although the organisms did not appear to correspond to any recognized species. Comparative 16S rRNA gene sequencing showed that the unknown bacterium was phylogenetically closely related to, but distinct from, Streptococcus suis (97.5 % 16S rRNA gene sequence similarity to the type strain). rpoB and sodA sequence analysis showed minimum interspecies divergence from phylogenetically close 16S rRNA gene sequence-based relatives of 13.8 and 18.6 %, respectively. DNA–DNA hybridization of a strain of the unidentified organism demonstrated 8–18 % reassociation with S. suis NCTC 10234T. The novel bacterium could be distinguished from S. suis and other Streptococcus species using biochemical tests. On the basis of phenotypic and phylogenetic evidence, it is proposed that the unknown isolates from domestic and wild animals be assigned to a novel species of the genus Streptococcus, Streptococcus porcorum sp. nov. The type strain is 682-03T ( = CCUG 58479T  = CECT 7593T).

The ammonia-producing bacteria B55T, CA73, SA69 and SA72 were isolated from the waterweeds Ludwigia adscendens (B55T) and Eleocharis dulcis (CA73, SA69 and SA72) grown in highly acidic swamps (pH 2–4) in actual acid sulfate soil areas of Vietnam. The isolates were Gram-positive, irregular rod-shaped, non-spore-forming bacteria. On the basis of 16S rRNA gene sequence similarity, strain B55T was shown to belong to the genus Curtobacterium of the class Actinobacteria. Chemotaxonomic data (MK-9 as major isoprenoid quinone, d-ornithine as cell-wall diamino acid, acetyl as the acyl type of peptidoglycan) supported the affiliation of all four strains to this genus. Although their 16S rRNA gene sequence similarity was 99 % to species with validly published names within the genus, they formed a group that was distinct in the phylogenetic tree, and DNA–DNA relatedness values to these established species were less than 10 %. The results of physiological and biochemical tests and major fatty acids (cyclohexyl-C17 : 0, anteiso-C17 : 0 and cyclohexyl-C19 : 0) allowed phenotypic differentiation of these strains from the species of Curtobacterium with validly published names. Therefore, strains B55T, CA73, SA69 and SA72 represent a novel species, for which the name Curtobacterium ammoniigenes sp. nov. is proposed. The type strain is B55T (=NBRC 101786T=VTCC D6-11T=JCM 14609T).
