Actinospica durhamensis sp. nov., isolated from a spruce forest soil.

ABSTRACT: Seven acidophilic actinobacteria isolated from humus and mineral layers of a spruce forest soil were examined using a polyphasic approach. Chemotaxonomic properties of the isolates were found to be consistent with their classification in the genus Actinospica. The strains formed a distinct phyletic line in the Actinospica 16S rRNA gene tree being most closely related to Actinospica robiniae DSM 44927(T) (98.7-99.3 % similarity). DNA:DNA relatedness between isolate CSCA57(T) and the type strain of A. robiniae was found to be low at 40.8 (±6.6) %. The isolates were shown to have many phenotypic properties in common and were distinguished readily from the type strains of Actinospica acidiphila and A. robiniae using a range of phenotypic features. On the basis of these data the seven isolates were considered to represent a new species for which the name Actinospica durhamensis sp. nov. is proposed. The type strain of the species is CSCA 57(T) (=DSM 46820(T) = NCIMB 14953(T)).

Nocardia aciditolerans sp. nov., isolated from a spruce forest soil.

Project description:Actinomycetes growing on acidified starch-casein agar seeded with suspensions of litter and mineral soil from a spruce forest were provisionally assigned to the genus Nocardia based upon colonial properties. Representative isolates were found to grow optimally at pH 5.5, have chemotaxonomic and morphological features consistent with their assignment to the genus Nocardia and formed two closely related subclades in the Nocardia 16S rRNA gene tree. DNA:DNA relatedness assays showed that representatives of the subclades belong to a single genomic species. The isolates were distantly associated with their nearest phylogenetic neighbour, the type strain of Nocardia kruczakiae, and were distinguished readily from the latter based on phenotypic properties. On the basis of these data it is proposed that the isolates merit recognition as a new species, Nocardia aciditolerans sp. nov. The type strain is isolate CSCA68(T) (=KACC 17155(T) = NCIMB 14829(T) = DSM 45801(T)).

Streptacidiphilus durhamensis sp. nov., isolated from a spruce forest soil.

Project description:The taxonomic position of three acidophilic actinobacteria, strains FGG38, FGG39 and FSCA67(T), isolated from the fermentation litter layer of a spruce forest soil was established using a polyphasic approach. The strains were shown to have chemotaxonomic and morphological properties consistent with their classification in the genus Streptacidiphilus and formed a distinct phyletic line in the Streptacidiphilus 16S rRNA gene tree being most closely related to Streptacidiphilus albus DSM 41753(T) (99.4 % similarity). DNA:DNA relatedness data showed that isolate FSCA67(T) and the type strain of S. albus belonged to markedly distinct genomic species. The isolates had many phenotypic properties in common and were distinguished readily from their closest phylogenetic neighbours in the Streptacidiphilus gene tree using a broad range of these features. Based on the combined genotypic and phenotypic data the three isolates are considered to represent a new Streptacidiphilus species. The name Streptacidiphilus durhamensis sp. nov. is proposed for this taxon with isolate FSCA67(T) (=DSM 45796(T) = KACC 17154(T) = NCIMB 14828(T)) [corrected] as the type strain.

Streptacidiphilus hamsterleyensis sp. nov., isolated from a spruce forest soil.

Project description:Three acidophilic actinobacteria, isolates LSCA2, FGG8 and HSCA14(T), recovered from spruce litter were examined using a polyphasic approach. Chemotaxonomic and morphological properties of the isolates were found to be consistent with their classification in the genus Streptacidiphilus. The isolates were shown to have identical 16S rRNA gene sequences and were most closely related to Streptacidiphilus neutrinimicus DSM 41755(T) (99.9 % similarity). However, DNA:DNA relatedness between isolate HSCA14(T) and the type strain of S. neutrinimicus was found to be low at 44.0 (±14.1) %. A combination of phenotypic features, including degradative and nutritional characteristics were shown to distinguish the isolates from their nearest phylogenetic neighbours. Data from this study show that the isolates form a novel species in the genus for which the name S. hamsterleyensis sp. nov. is proposed. The type strain is HSCA 14(T) (=DSM 45900(T) = KACC 17456(T) = NCIMB 14865(T)).

Streptacidiphilus toruniensis sp. nov., isolated from a pine forest soil.

Project description:Two acidophilic actinobacteria, isolates NA14 and NF37T, were the subject of a polyphasic taxonomic study. Chemotaxonomic and morphological properties of the isolates were characteristic of the genus Streptacidiphilus. The isolates were shown to have identical 16S rRNA gene sequences and to be closely related to Streptacidiphilus neutrinimicus DSM 41755T (>99.9 %). However, DNA:DNA relatedness between isolate NF37T and the type strain of S. neutrinimicus was found to be low at 11.1 (±3.5) %. A broad range of phenotypic features were shown to distinguish the isolates from their close phylogenetic neighbours. These data shown that the isolates form a novel species of Streptacidiphilus for which the name Streptacidiphilus toruniensis sp. nov. is proposed. The type strain is NF37T (= DSM 102291T = NCIMB 15025T).

<i>Streptomyces silvae</i> sp. nov., isolated from forest soil.

Project description:A bacterial strain, named For3T, was isolated from forest soil sampled in Champenoux, France. Based on its 16S rRNA gene sequence, the strain was affiliated to the family Streptomycetaceae and, more specifically, to the genus Streptomyces. The strain had 99.93% 16S rRNA gene sequence similarity to its closest relative strains Streptomyces pratensis ATCC 33331T, Streptomyces anulatus ATCC 27416T, Streptomyces setonii NRRL ISP-5322T and Kitasatospora papulosa NRRL B-16504T. The phylogenomic tree using the genome blast distance phylogeny method showed that the closest relative strain was Streptomyces atroolivaceus NRRL ISP-5137T and that For3T represents a new branch among the Streptomyces. Genome relatedness indexes revealed that the average nucleotide identity and digital DNA-DNA hybridization values between For3T and its closest phylogenomic relative (S. atroolivaceus NRRL ISP-5137T) were 88.39 and 39.2 %, respectively. The G+C content of the genome was 71.4 mol% and its size was 7.96 Mb with 7492 protein-coding genes. Strain For3T harboured complete metabolic pathways absent in the closest relative strains such as cellulose biosynthesis, glycogen degradation I, glucosylglycerate biosynthesis I. Anteiso-C15:0, iso-C15:0, anteiso-C17:0 and MK-9(H4)/MK-9(H6) were the predominant cellular fatty acids and respiratory quinones, respectively. Phenotypic and genomic data supported the assignment of strain For3T to a novel species Streptomyces silvae sp. nov., within the genus Streptomyces, for which the type strain is For3T (=CIP 111908T=LMG 32186T).

Effusibacillus dendaii sp. nov. isolated from farm soil.

Project description:A Gram-positive, rod-shaped, spore-forming, thermophilic, and acidophilic bacterium, designated as strain skT53T, was isolated from farm soil in Tokyo, Japan. Under aerobic conditions, the strain grew at 35-55 °C (optimum temperature 44-55 °C) and pH 4.0-6.0 (optimum pH 5.0). Phylogenetic analysis of the 16S rRNA gene sequence showed that the isolate was moderately related to the type strain of Effusibacillus consociatus (94.3% similarity). The G + C content of the genomic DNA was 48.2 mol%, and MK-7 was the predominant respiratory quinone in the strain. The major fatty acids were anteiso-C15:0, iso-C15:0, and iso-C16:0. Based on the phenotypic and chemotaxonomic characteristics, as well as 16S rRNA gene sequence similarity and whole genome analyses, strain skT53T represents a novel species in the genus Effusibacillus, for which the name Effusibacillus dendaii sp. nov. has been proposed. The type strain is skT53T (= NBRC 114101 T = TBRC 11241 T).

Allokutzneria multivorans sp. nov., an actinomycete isolated from soil.

Project description:An actinomycete with well-branched mycelia, designated strain YIM 120521(T), was isolated from soil collected from the banks of the Nujiang River, Yunnan Province, south-west China. Both aerial and substrate mycelia were white and non-pigmented. Growth was observed at 4-40 °C (optimum 28 °C), pH 6.0-9.0 (optimum 7.0) and in 0-4?% (w/v) NaCl (optimum 0?%). Analysis of the 16S rRNA gene sequence revealed that strain YIM 120521(T) belongs to the genus Allokutzneria with the highest sequence similarity to Allokutzneria albata DSM 44149(T) (98.4?%). However, the mean DNA-DNA relatedness value between the two strains was below 70?%. Chemotaxonomic characteristics supported the inclusion of strain YIM 120521(T) in the genus Allokutzneria, with rhamnose, arabinose, glucose, galactose and mannose as the whole-cell sugars, meso-diaminopimelic acid as the cell-wall diamino acid and MK-9(H4) as the predominant menaquinone. On the basis of physiological, biochemical and chemotaxonomic characteristics, strain YIM 120521(T) is considered to represent a novel species of the genus Allokutzneria, for which the name Allokutzneria multivorans sp. nov. is proposed. The type strain is YIM 120521(T) (?=?JCM 17342(T)?=?DSM 45532(T)).

Nonomuraea soli sp. nov., an actinomycete isolated from soil.

Project description:A straight-chain, spore-forming actinobacterium, strain YIM 120770(T), was isolated from soil. Phylogenetic analysis on the basis of 16S rRNA gene sequence comparisons revealed that the isolate represents a distinct cluster within the clade comprising the genus Nonomuraea and is related most closely to Nonomuraea rhizophila YIM 67092(T) (96.5% similarity). Cells of strain YIM 120770(T) grew in the presence of 0-3% (w/v) NaCl, at 15-37 °C and at pH 7.0-8.0. The diagnostic amino acid was meso-diaminopimelic acid, cell hydrolysates contained madurose, glucose, mannose, ribose and galactose, the predominant cellular fatty acids were 10-methyl C(17:0) and iso-C(16:0), and the DNA G+C content was 66.4 mol%, data consistent with affiliation of strain YIM 120770(T) to the genus Nonomuraea. Strain YIM 120770(T) shared low levels of 16S rRNA gene sequence similarity (<97%) with the type strains of recognized species of the genus Nonomuraea and could be differentiated from its closest phylogenetic relative based on phenotypic characteristics. These results suggested that strain YIM 120770(T) represents a novel species of the genus Nonomuraea, for which the name Nonomuraea soli sp. nov. is proposed. The type strain is YIM 120770(T) (=DSM 45533(T)=JCM 17347(T)).

Rhodococcus daqingensis sp. nov., isolated from petroleum-contaminated soil.

Project description:A novel Gram-stain positive, aerobic, non-motile bacterial strain, designated Z1T, was isolated from a sample of petroleum-contaminated soil collected in Daqing, Heilongjiang province, China and characterised with a series of taxonomic approaches. The morphological and chemotaxonomic properties of the isolate were typical of those of members of the genus Rhodococcus. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Z1T belongs to the genus Rhodococcus and clustered with Rhodococcus maanshanensis DSM 44675T (99.2%, sequence similarity) and Rhodococcus tukisamuensis JCM 11308T (97.9%), respectively. However, the DNA-DNA hybridizations between strain Z1T and R. maanshanensis DSM 44675T and R. tukisamuensis JCM 11308T were both less than 70%. The optimal growth temperature and pH for strain Z1T were found to be at 28 °C and at pH 7.0. The peptidoglycan was found to contain meso-diaminopimelic acid; arabinose, galactose and glucose were detected as diagnostic sugars. The main polar lipids were identified as diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and an unidentified lipid; MK-8(H2) was found as the major menaquinone. The major fatty acids were identified as C16:0, 10-methyl C18:0 and C18:1ω9c. Mycolic acids were found to be present. The G + C content of the genomic DNA was determined to be 66.7 mol%. Based on a comparative analysis of phenotypic and genotypic characteristics, in combination with DNA-DNA hybridization results, strain Z1T can be distinguished from the type strains of its two close neighbours as a novel species of the genus Rhodococcus, for which the name Rhodococcus daqingensis sp. nov. is proposed. The type strain is Z1T (= CGMCC 1.13630T = DSM 107227T).

Verrucosispora rhizosphaerae sp. nov., isolated from mangrove rhizosphere soil.

Project description:An actinomycete strain, 2603PH03T, was isolated from a mangrove rhizosphere soil sample collected in Wenchang, China. Phylogenetic analysis of the 16S rRNA gene sequence of strain 2603PH03T indicated high similarity to Verrucosispora gifthornensis DSM 44337T (99.4%), Verrucosispora andamanensis (99.4%), Verrucosispora fiedleri MG-37T (99.4%) and Verrucosispora maris AB18-032T (99.4%). The cell wall was found to contain meso-diaminopimelic acid and glycine. The major menaquinones were identified as MK-9(H4), MK-9(H6) and MK-9(H8), with MK-9(H2), MK-10(H2), MK-9(H10) and MK-10(H6) as minor components. The characteristic whole cell sugars were found to be xylose and mannose. The phospholipid profile was found to contain phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, phosphatidylserine and an unidentified phospholipid. The DNA G+C content was determined to be 70.1 mol%. The results of physiological and biochemical tests and low DNA-DNA relatedness readily distinguished the isolate from the closely related species. On the basis of these phenotypic and genotypic data, strain 2603PH03T is concluded to represent a novel species of the genus Verrucosispora, for which the name Verrucosispora rhizosphaerae sp. nov. is proposed. The type strain is 2603PH03T (=CCTCC AA 2016023T = DSM 45673T).
