Polar Lipid Profile

A Gram-positively staining, aerobic, non-motile actinomycete, strain GW 12687T, that formed rose-pigmented colonies and branched substrate and aerial mycelia was studied in detail for its taxonomic position. On the basis of 16S rRNA gene sequence similarity studies, strain GW 12687T was grouped into the genus Nonomuraea, being most closely related to Nonomuraea dietziae (97.6 %), Nonomuraea africana (97.1 %), and Nonomuraea kuesteri (97.1 %). The 16S rRNA gene sequence similarity to other species of the genus Nonomuraea was ≤97 %. The chemotaxonomic characterization supported allocation of the strain to the genus Nonomuraea. The major menaquinone was MK-9(H4) with minor amounts of MK-9(H2), MK-9(H6), MK-9(H0) and MK-8(H4). The polar lipid profile contained the major compound diphosphatidylglycerol, moderate amounts of phosphatidylmonomethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, hydroxy-phosphatidylmonomethylethanolamine, and an unknown aminophosphoglycolipid. Phosphatidylinositol mannosides and phosphatidylinositol were also present. The major fatty acids were iso- and anteiso- and 10-methyl-branched fatty acids. The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW 12687T from closely related species. Thus, GW 12687T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea rosea sp. nov. is proposed, with GW 12687T (=DSM 45177T =CCUG 56107T) as the type strain.

Polar Lipid Profile

A Gram-negative, oxidase- and catalase-positive, flagellated, rod-shaped bacterium, designated strain EM 1T, was isolated from purified water. 16S rRNA gene sequence analysis indicated that the novel strain belonged to the family Oxalobacteraceae within the class Betaproteobacteria; the closest phylogenetic relative was Undibacterium pigrum DSM 19792T (96.7 % gene sequence similarity). The new isolate could be distinguished from the type strain of U. pigrum DSM 19792T (=CCUG 49009T=CIP 109318T) and from strain CCUG 49012T, which has been described as a second genomovar of this species, on the basis of genotypic data and several phenotypic properties. An S-layer was present in the cell envelope in U. pigrum DSM 19792T, but was absent in strains EM 1T and CCUG 49012T. Test conditions were established that enabled strain CCUG 49012T to be distinguished from U. pigrum DSM 19792T. As found for U. pigrum, the main fatty acids of strains EM 1T and CCUG 49012T were summed feature 3 (including unsaturated C16 : 1 ω7c), straight-chain C16 : 0 and unsaturated C18 : 1 ω7c (low percentage in strain CCUG 49012T), and C10 : 0 3-OH was the sole hydroxylated fatty acid. The polar lipid profile consisted of the predominant lipids phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The polyamine profile was mainly composed of the major compound putrescine and moderate amounts of 2-hydroxyputrescine. In contrast to U. pigrum and strain CCUG 49012T, where ubiquinone Q8 was reported as the sole quinone component, the quinone system of strain EM 1T consisted of ubiquinone Q-8 (64 %) and Q-7 (36 %). The 16S rRNA gene sequence similarity, the polar lipid profile and the absence of C12-hydroxylated fatty acids all indicated that strain EM 1T was affiliated with the genus Undibacterium. 16S rRNA gene sequence similarity values lower than 97.0 % and several differentiating phenotypic traits demonstrated that strain EM 1T represents a novel species for which the name Undibacterium oligocarboniphilum sp. nov. is proposed (type strain EM 1T=DSM 21777T=CCUG 57265T). In addition, based on previously published results and this study, a separate species, Undibacterium parvum sp. nov., is proposed with strain CCUG 49012T (=DSM 23061T=CIP 109317T) as the type strain.

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, non-motile actinomycete, strain GW 14-1925T, that formed branched substrate and aerial mycelium was studied using a polyphasic approach. On the basis of 16S rRNA gene sequence similarity studies, strain GW 14-1925T was shown to belong to the genus Nonomuraea, being most closely related to Nonomuraea longicatena (97·9 %), Nonomuraea turkmeniaca (98·9 %), Nonomuraea helvata (98·6 %), Nonomuraea polychroma (98·5 %), Nonomuraea salmonaea (98·3 %), Nonomuraea roseoviolacea subsp. roseoviolacea (98·1 %) and Nonomuraea roseoviolacea subsp. carminata (97·7 %). The 16S rRNA gene sequence similarity to other Nonomuraea species was <97·5 %. Chemotaxonomic data [major menaquinones of the MK-9 series with minor amounts of MK-8(H4); major polar lipids of phospholipid type IV; fatty acids with major amounts of iso- and anteiso- and 10-methyl-branched fatty acids in combination with iso-branched 2-hydroxy fatty acids] supported allocation of the strain to the genus Nonomuraea. The results of DNA–DNA hybridizations and physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain GW 14-1925T from closely related species; thus, GW 14-1925T represents a novel species of the genus Nonomuraea, for which the name Nonomuraea kuesteri sp. nov. is proposed, with GW 14-1925T (=DSM 44753T=NRRL B-24325T) as the type strain.

AbstractStrain M2T was isolated from the beach of Cuxhaven, Wadden Sea, Germany, in course of a program to attain new producers of bioactive natural products. Strain M2T produces litoralimycin and sulfomycin-type thiopeptides. Bioinformatic analysis revealed a potential biosynthetic gene cluster encoding for the M2T thiopeptides. The strain is Gram-stain-positive, rod shaped, non-motile, spore forming, showing a yellow colony color and forms extensively branched substrate mycelium and aerial hyphae. Inferred from the 16S rRNA gene phylogeny strain M2T affiliates with the genus Streptomonospora. It shows 96.6% 16S rRNA gene sequence similarity to the type species Streptomonospora salina DSM 44593 T and forms a distinct branch with Streptomonospora sediminis DSM 45723 T with 97.0% 16S rRNA gene sequence similarity. Genome-based phylogenetic analysis revealed that M2T is closely related to Streptomonospora alba YIM 90003 T with a digital DNA-DNA hybridisation (dDDH) value of 26.6%. The predominant menaquinones of M2T are MK-10(H6), MK-10(H8), and MK-11(H6) (> 10%). Major cellular fatty acids are iso-C16:0, anteiso C17:0 and C18:0 10-methyl. The polar lipid profile consisted of diphosphatidylglycerol phosphatidyl glycerol, phosphatidylinositol, phosphatidylcholine, phosphatidylethanolamine, three glycolipids, two unknown phospholipids, and two unknown lipids. The genome size of type strain M2T is 5,878,427 bp with 72.1 mol % G + C content. Based on the results obtained from phylogenetic and chemotaxonomic studies, strain M2T (= DSM 106425 T = NCCB 100650 T) is considered to represent a novel species within the genus Streptomonospora for which the name Streptomonospora litoralis sp. nov. is proposed.

Thirteen bacterial isolates from lake sediment, capable of degrading cyanobacterial hepatotoxins microcystins and nodularin, were characterized by phenotypic, genetic and genomic approaches. Cells of these isolates were Gram-negative, motile by means of a single polar flagellum, oxidase-positive, weakly catalase-positive and rod-shaped. According to phenotypic characteristics (carbon utilization, fatty acid and enzyme activity profiles), the G+C content of the genomic DNA (66·1–68·0 mol%) and 16S rRNA gene sequence analysis (98·9–100 % similarity) the strains formed a single microdiverse genospecies that was most closely related to Roseateles depolymerans (95·7–96·3 % 16S rRNA gene sequence similarity). The isolates assimilated only a few carbon sources. Of the 96 carbon sources tested, Tween 40 was the only one used by all strains. The strains were able to mineralize phosphorus from organic compounds, and they had strong leucine arylamidase and chymotrypsin activities. The cellular fatty acids identified from all strains were C16 : 0 (9·8–19 %) and C17 : 1 ω7c (<1–5·8 %). The other predominant fatty acids comprised three groups: summed feature 3 (<1–2·2 %), which included C14 : 0 3-OH and C16 : 1 iso I, summed feature 4 (54–62 %), which included C16 : 1 ω7c and C15 : 0 iso OH, and summed feature 7 (8·5–28 %), which included ω7c, ω9c and ω12t forms of C18 : 1. A more detailed analysis of two strains indicated that C16 : 1 ω7c was the main fatty acid. The phylogenetic and phenotypic features separating our strains from recognized bacteria support the creation of a novel genus and species, for which the name Paucibacter toxinivorans gen. nov., sp. nov. is proposed. The type strain is 2C20T (=DSM 16998T=HAMBI 2767T=VYH 193597T).

Separate Species

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.

The Family

Four Gram-negative, orange-coloured, aerobic, heterotrophic bacteria were isolated from sediment samples collected on the Pacific coast of Japan near the cities of Toyohashi and Katsuura. 16S rRNA gene sequence analysis indicated that these strains form a distinct lineage within the family Flavobacteriaceae. The four isolates shared 99.9–100 % 16S rRNA gene sequence similarity with each other and showed 88–90.9 % similarity with their neighbours in the family Flavobacteriaceae. The four strains also shared high DNA–DNA reassociation values of 67–99 % with each other. All the strains grew at 37 °C but not at 4 °C, and degraded gelatin, starch and DNA. The major fatty acids were i-C15 : 0, a-C15 : 0, i-C16 : 0 and i-C17 : 0 3-OH. However, two common fatty acids of members of the Flavobacteriaceae, i-C15 : 1 and a-C15 : 1, were absent in these strains. The DNA G+C contents of the four strains were in the range 35–37 mol%. On the basis of the polyphasic evidence, it was concluded that these strains should be classified as a novel genus and a novel species in the family Flavobacteriaceae, for which the name Sandarakinotalea sediminis gen. nov., sp. nov. is proposed. The type strain of Sandarakinotalea sediminis is CKA-5T (=NBRC 100970T=LMG 23247T).

Bacterium Strain

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).

Bacterium Strain

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).

Pyrenean Chamois

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).
