An amoeba strain was isolated from marine sediment taken from the beach near a fumarole in Italy. The trophozoites of this new marine species transforms into flagellates with variable numbers of flagella, from 2 to 10. The strain forms round to oval cysts. This thermophilic amoeboflagellate grows at temperatures up to 54 °C. Molecular phylogenetic analysis of the small subunit ribosomal DNA (SSU rDNA) places the amoeboflagellate in the Heterolobosea. The closest relatives are Stachyamoeba sp. ATCC50324, a strain isolated from an ocean sample, and Vrihiamoeba italica, a recent isolate from a rice field. Like some other heterolobosean species, this new isolate has a group I intron in the SSU rDNA. Because of the unique place in the molecular phylogenetic tree, and because there is no species found in the literature with similar morphological and physiological characteristics, this isolate is considered to be a new genus and a new species, Oramoeba fumarolia gen. nov., sp. nov. 相似文献

Flavobacterium columnare is the causative agent of columnaris disease in freshwater fish and four discrete genetic groups exist within the species, suggesting that the species designation requires revision. The present study determined the taxonomic status of the four genetic groups of F. columnare using polyphasic and phylogenomic approaches and included five representative isolates from each genetic group (including type strain ATCC 23463 T; genetic group 1). 16S rRNA gene sequence analysis revealed genetic group 2 isolate AL-02-36 T, genetic group 3 isolate 90-106 T, and genetic group 4 isolate Costa Rica 04-02-TN T shared less than <98.8 % sequence identity to F. columnare ATCC 23463 T. Phylogenetic analyses of 16S rRNA and gyrB genes using different methodologies demonstrated the four genetic groups formed well-supported and distinct clades within the genus Flavobacterium. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (GGDC) values between F. columnare ATCC 23463 T, genetic group 2 isolate AL-02-36 T, genetic group 3 isolate 90-106 T, and genetic group 4 isolate Costa Rica 04-02-TN T were less than 90.84% and 42.7%, respectively. Biochemical and physiological characteristics were similar among the four genetic groups; however, quantitative differences in fatty acid profiles were detected and MALDI-TOF analyses demonstrated numerous distinguishing peaks unique to each genetic group. Chemotaxonomic, MALDI-TOF characterization and ANI/GGDC calculations afforded differentiation between the genetic groups, indicating each group is a discrete species. Herein, the names F. covae sp. nov. (AL-02-36 T), F. davisii sp. nov. (90-106 T), and F. oreochromis sp. nov. (Costa Rica 04-02-TN T) are proposed to represent genetic groups 2, 3, and 4, respectively. 相似文献

Twelve Mycoplasma ( M.) strains isolated from the nose, the trachea, and the lung of ostriches (Struthio camelus) displaying respiratory disease were investigated. Analysis of 16S rRNA gene sequences placed five of these strains within the M. synoviae cluster, and seven strains within the M. hominis cluster of genus Mycoplasma, which was further confirmed by analyses of the 16S-23S rRNA intergenic spacer region, and partial rpoB gene and amino acid sequences. Genomic information as well as phenotypic features obtained by matrix-assisted laser desorption ionization time of flight (MALDI-ToF) mass spectrometry analysis and serological reactions indicated that the strains examined are representatives of two hitherto unclassified species of genus Mycoplasma, for which the names Mycoplasma nasistruthionis sp. nov., with type strain 2F1A T (= ATCC BAA-1893 T = DSM 22456 T), and Mycoplasma struthionis sp. nov., with type strain 237IA T (= ATCC BAA-1890 T = DSM 22453 T), are proposed. 相似文献

Three Gram-negative bacterial strains were isolated from the biofilter of a recirculating marine aquaculture. They were non-pigmented rods, mesophiles, moderately halophilic, and showed chemo-organoheterotrophic growth on various sugars, fatty acids, and amino acids, with oxygen as electron acceptor; strains D9-3 T and D11-58 were in addition able to denitrify. Phototrophic or fermentative growth could not be demonstrated. Phylogenetic analysis of the 16S rRNA gene sequences placed D9-3 T and D11-58, and D1-19 T on two distinct branches within the alpha-3 proteobacterial Rhodobacteraceae, affiliated with, but clearly separate from, the genera Rhodobacter, Rhodovulum, and Rhodobaca. Based on morphological, physiological, and 16S rRNA-based phylogenetic characteristics, the isolated strains are proposed as new species of two novel genera, Defluviimonas denitrificans gen. nov., sp. nov. (type strain D9-3 T = DSM 18921 T = ATCC BAA-1447 T; additional strain D11-58 = DSM19039 = ATCC BAA-1448) and Pararhodobacter aggregans gen. nov., sp. nov (type strain D1-19 T = DSM 18938 T = ATCC BAA-1446 T). 相似文献

A novel bacterial strain, designated ARSA-111 T, was isolated from a freshwater reservoir in Cheonan, Korea. Phylogenetic analysis based on 16S rRNA gene sequences suggested that the isolate belonged to the genus Flavobacterium of phylum Bacteroidetes. The 16S rRNA gene sequence of strain ARSA-111 T showed a high degree of sequence similarity to those of Flavobacteium cheonanense KACC 14972 T (97.3%), F. aquatile JCM 20475 T (97.1%), and other type strains of the genus Flavobacterium (< 97.0%). The phylogenetic tree and network analysis (i.e. median-joining) based on 16S rRNA gene sequences showed that strain ARSA-111 T is most closely related to F. aquatile JCM 20475 T. DNA-DNA hybridization experiment revealed 70% of genomic relatedness among strain ARSA-111 T, F. aquatile JCM 20475 T and F. cheonanense KACC 14972 T. The isolate had iso-C 15:1, iso-C 15:0, and iso-C 15:0 3-OH as predominant cellular fatty acids and MK-6 as a predominant menaquinone. The genomic DNA G+C content of the isolate was 35.6 mol%. On the basis of these data, strain ARSA-111 T is considered to be a novel species of the genus Flavobacterium, for which the name Flavobacterium aquaticum sp. nov. is proposed. The type strain is strain ARSA-111 T (=KACC 14973 T =KCTC 23185 T = JCM 17070 T). 相似文献

The taxonomic positions of five Gram-negative, non-spore-forming and non-motile bacterial strains isolated from the rhizosphere of sand dune plants were examined using a polyphasic approach. The analysis of the 16S rRNA gene sequence indicated that all of the isolates fell into four distinct phylogenetic clusters belonging to the genus Chryseobacterium of the family Flavobacteriaceae. The 16S rRNA gene sequence similarities of isolates to mostly related type strains of Chryseobacterium ranged from 97.5% to 98.5%. All strains contained MK-6 as the predominant menaquinone, and iso-C 15:0, iso-C 17:0 3-OH and a summed feature of iso-C 15:0 2-OH and/or C 16:1 ω7c as the dominant fatty acids. Combined phenotypic, genotypic and chemotaxonomic data supported that they represented four novel species in the genus Chryseobacterium, for which the names Chryseobacterium hagamense sp. nov. (type strain RHA2-9 T=KCTC 22545 T=NBRC 105253 T), Chryseobacterium elymi sp. nov. (type strain RHA3-1 T=KCTC 22547 T=NBRC 105251 T), Chryseobacterium lathyri sp. nov. (type strain RBA2-6 T=KCTC 22544 T=NBRC 105250 T), and Chryseobacterium rhizosphaerae sp. nov. (type strain RSB3-1 T=KCTC 22548 T=NBRC 105248 T) are proposed. 相似文献

The taxonomic position of a streptomycete isolated from a potato tubercle was determined by using a polyphasic approach. The organism had chemotaxonomic and morphological properties consistent with its classification in the genus Streptomyces and formed a distinct phyletic line in the Streptomyces 16S rRNA gene tree. It was found to be closely related to Streptomyces celluloflavus NRRL B-2493 T (99.4 % 16S rRNA gene similarity) and shared a 99.0 % 16S rRNA gene similarity value with Streptomyces albolongus NRRL B-3604 T and Streptomyces cavourensis subsp. cavourensis NBRC 13026 T; low levels of DNA–DNA relatedness with these organisms showed that the isolate belonged to a distinct genomic species. The isolate was distinguished readily from the type strains of these species using a combination of morphological and other phenotypic properties. On the basis of these results, it is proposed that isolate ASBV-1 T (= CBMAI 1465 T = CCMA 894 T = NRRL B-24922 T) be classified as the type strain of Streptomyces araujoniae sp. nov. 相似文献

Two isolates, with an optimum growth temperature of about 35-37 °C and an optimum pH for growth between 6.5 and 7.5, were recovered from a deep mineral water aquifer in Portugal. Strains form rod-shaped cells and were non-motile. These strains were non-pigmented, strictly aerobic, catalase and oxidase positive. Strains F2-233 T and F2-223 assimilated carbohydrates, organic acids and amino acids. Major fatty acids were novel iso internally branched such as 17:0 iso 10-methyl, 17:0 iso and 15:0 iso 8-methyl. The peptidoglycan contained meso-diaminopimelic acid and menaquinone MK-7 was the major respiratory quinone. Analysis of the 16S rRNA gene shows the strains to cluster with species of the genera Thermoleophilum, Patulibacter, Conexibacter and Solirubrobacter to which they have pairwise sequence similarity in the range 87-88%. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics we describe a new species of a novel genus represented by strain F2-233 T (=CECT 7815 T = LMG 26412 T) for which we propose the name Gaiella occulta gen. nov., sp. nov. We also propose that this organism represents a novel family named Gaiellaceae fam. nov. of a novel order named Gaiellales ord. nov. 相似文献

The bacterial symbiont of the entomopathogenic nematode Heterorhabditis bacteriophora strain GPS11 was characterized by 16S rRNA gene sequence and physiological traits. The phylogenetic tree built upon 16S rRNA
gene sequences clustered the GPS11 bacterial isolate with Photorhabdus temperata strains which have been previously isolated from Heterorhabditis species. The phylogenetic tree further identified four subgroups in P. temperata, and the relationships among these subgroups were confirmed by gyrase subunit B ( gyrB) gene sequence analysis. The subgroup containing the GPS11 bacterial isolate differs from other subgroups in sequences of
16S rRNA and gyrB gene, physiological traits, nematode host species, and geographic origin. Therefore, the subgroup comprising the GPS11 bacterial
isolate is proposed here as a new subspecies: Photorhabdus temperata subsp. stackebrandtii subsp. nov. (type strain GPS11). The type strain has been deposited in ATCC and DSMZ collections. 相似文献

Isolate W14 T recovered from a household tooth brush holder was found to be gram-negative, a facultative anaerobic, non-motile, capsulated, and a non-endospore-forming straight rod. Based on phylogenetic analysis with 16S rRNA gene sequence, isolate W14 T was affiliated to the genus Klebsiella. The closest phylogenetic relative was K. oxytoca with 99 % similarity in the 16S rRNA gene sequence. The major whole-cell fatty acids were C 16:0 (31.23 %), C 18:1ω6c/C 18:1ω7c (21.10 %), and C 16:1ω7c/C 16:1ω6c (19.05 %). The sequence similarities of isolate W14 T based on rpoB, gyrA, and gyrB were 97, 98, and 98 % with K. oxytoca, and 97, 93, and 90 % with K. mobilis (= Enterobacter aerogenes), respectively. The ribotyping pattern showed a 0.46 similarity with K. oxytoca ATCC 13182 T and 0.24 with K. mobilis ATCC 13048 T. The DNA G+C content of isolate W14 T was 54.6 mol%. The DNA–DNA relatedness was 55.7 % with K. oxytoca ATCC 13182 T. Using the identification technology of MALDI-TOF mass spectrometry, the top matches for this isolate were K. oxytoca ATCC 13182 T (Match Factor Score 1.998) and K. mobilis (Score 1.797). On the basis of phenotypic, biochemical, chemotaxonomic, and molecular studies, isolate W14 T could be differentiated from other members of the genus Klebsiella including K. mobilis. Therefore, it is proposed that isolate W14 T (=ATCC BAA-2403 T=DSM 25444 T) should be classified as the type strain of a novel species of the genus Klebsiella, K. michiganensis sp. nov. 相似文献

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 14829 T) as the type strain. 相似文献

A Gram-negative, strictly aerobic, golden-yellow pigmented, non-motile, rod-shaped strain designated J36A-7 T was isolated from an unidentified yellow-green coloured marine sponge. Phylogenetic analyses based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the family Flavobacteriaceae of the phylum Bacteroidetes and that it showed highest sequence similarity (85.6 %) to Nonlabens dokdonensis DSW-6 T. The strain could be differentiated phenotypically from recognized members of the family Flavobacteriaceae. The major fatty acids of strain J36A-7 T were identified as iso-C16:0, iso-C17:0 3-OH and summed feature three as defined by the MIDI system (C16:1 ω7c and/or iso-C15:0 2-OH). The DNA G+C content was determined to be 31.2 mol%, the major respiratory quinone was identified as menaquinone 6 (MK-6) and a complex polar lipid profile was present consisting of phosphatidylethanolamine, two unidentified glycolipids, one unidentified aminolipid and one unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus for which the name Spongiimonas flava gen. nov., sp. nov. is proposed. The type strain of S. flava is J36A-7 T (=KCTC 32176 T = NBRC 109319 T). 相似文献

A Gram-negative, strictly aerobic, reddish-pink pigmented, motile, spherical, agar-degrading bacterium designated 06SJR6-2 T was isolated from a green coloured marine alga ( Cladophora sp.). Phylogenetic analyses based on the 16S rRNA gene sequence indicated that the new strain was affiliated with the class Phycisphaerae and shared 89.2 % sequence similarity with Phycisphaera mikurensis FYK2301M01 T, which is the only validly named member of the class Phycisphaerae. The strain could be differentiated phenotypically from the recognised member of the class Phycisphaerae. The major fatty acids of strain 06SJR6-2 T were identified as C16:0, C18:1 ω9c and anteiso-C15:0. Amino acid analysis of cell wall hydrolysates indicated that the novel isolate did not contain diaminopimelic acid in the cell wall. The DNA G+C content of the strain was determined to be 63.0 mol% and the major respiratory quinone was identified as menaquinone 6 (MK-6). From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel genus in the family Phycisphaeraceae, for which the name Algisphaera agarilytica gen. nov., sp. nov. is proposed. The type strain of A. agarilytica is 06SJR6-2 T (=KCTC 32482 T = NBRC 109894 T). 相似文献

A novel actinobacterium, designated strain MSW-19 T, was isolated from a seawater sample in Republic of Korea. Cells were aerobic, Gram-positive, non-endospore-forming, and
non-motile cocci. Colonies were circular, convex, opaque, and vivid yellow in colour. A phylogenetic tree based on 16S rRNA
gene sequences exhibited that the organism formed a distinct clade within the radius encompassing representatives of the family
Propionibacteriaceae. The phylogenetic neighbors were the type strains of the genera Friedmanniella, Microlunatus, Micropruina, Propionicicella, and Propionicimonas. Levels of 16S rRNA gene sequence similarity between the isolate and members of the family were less than 95.3%. The cell
wall peptidoglycan of the organism contained LL-diaminopimelic acid as the diagnostic diamino acid. The isolate contained
MK-9(H 4) as the predominant menaquinone, ai-C 15:0 as the major fatty acid and polar lipids including phosphatidylglycerol, phosphatidylethanolamine, and an unknown phospholipid.
The G+C content of the DNA was 69.6 mol%. On the basis of the phenotypic and phylogenetic data presented here, the isolate
is considered to represent a novel genus and species in the family Propionibacteriaceae, for which the name Ponticoccus gilvus gen. nov., sp. nov. is proposed. The type strain is strain MSW-19 T (= KCTC 19476 T= DSM 21351 T). 相似文献

The Streptomyces phylogroup pratensis (Doroghazi and Buckley, 2010) contains isolates obtained from grassy fields, as well as Streptomyces flavogriseus ATCC 33331 and strain CGMCC 4.1868. This latter strain was received as Streptomyces griseoplanus but was subsequently found to be mislabeled, and S. flavogriseus ATCC 33331 (=IAF-45-CD) was shown to be clearly distinct from the type strain S. flavogriseus ATCC 25452 T (=CGMCC 4.1884 T). In order to evaluate the taxonomic position of phylogroup pratensis further, sequences of the 16S rRNA gene and five protein-coding housekeeping genes ( atpD, gyrB, recA, rpoB and trpB) were determined for six strains of the phylogroup and type strains of 19 related species, which were selected by a BLAST search based on the sequences of the phylogroup. The 16S rRNA gene sequences for the phylogroup were identical to those of eight species belonging to cluster I of the S. griseus clade. However, in all the individual protein-coding gene and MLSA phylogenies, the phylogroup strains without exception formed an obviously distinct cluster that could be equated with a new species status. The phylogenetic evidence for the new species assignment was also supported by corresponding DNA–DNA hybridization values and by phenotypic characteristics. It is therefore proposed that the phylogroup should be classified as Streptomyces pratensis sp. nov., and the type strain is ch24 T (=CGMCC 4.6829 T = NRRL B-24916 T). 相似文献

An actinobacterial strain, designated YC3-6T, was isolated from a larva cave in Jeju, Republic of Korea. The novel isolate was found to grow at 10–30 °C, pH 5.0–10.0 and 0–4% (w/v) NaCl. The 16S rRNA gene phylogeny showed that the novel isolate formed a distinct subline within the family Nocardiaceae. Levels of 16S rRNA gene similarity indicated that the close relatives are Rhodococcus cavernicola (98.4% sequence similarity) and “Rhodococcus psychrotolerans” (98.2%) followed by Antrihabitans stalactiti (96.8%). However, the core gene-based phylogeny revealed that the novel isolate formed a tight cluster with A. stalactiti and was separated from R. cavernicola and other members of the family Nocardiaceae. The morphological and chemotaxonomic characteristics of strain YC3-6T are in line with those of the genus Antrihabitans. Strain YC3-6T showed an average nucleotide identity of 75.5% and a digital DDH of 20.3% with A. stalactiti. In addition, the core gene analysis showed that R. cavernicola formed a distinct subline between an Antrihabitans cluster and Aldersonia kunmingensis, and well separated from members of the genus Rhodococcus. The average amino acid identity values of R. cavernicola to closely related neighbours were 69.3–69.4% with members of the genus Antrihabitans and 67.3% with Ald. kunmingensis, while the POCP values ranged from 56.9 to 63.6%. On the basis of results obtained here, strain YC3-6T is concluded to represent a novel species of the genus Antrihabitans, for which the name Antrihabitans stalagmiti sp. nov. (type strain, YC3-6T?=?KACC 19963T?=?DSM 107561T) is proposed. Based on overall genome relatedness and chemotaxonomic differences, it is also proposed that R. cavernicola Lee et al. 2020 be transferred to a new genus Spelaeibacter as Spelaeibacter cavernicola gen. nov., comb. nov. 相似文献

A Streptomyces strain isolated from a hyper-arid Atacama Desert soil was characterised using a polyphasic taxonomic approach. The strain, designated C2 T, had chemical and morphological properties typical of the genus Streptomyces. The isolate formed a branch in the Streptomyces 16S rRNA gene tree together with the type strain of Streptomyces chromofuscus and was also loosely related to Streptomyces fragilis NRRL 2424 T. DNA:DNA relatedness values between the isolate and its two phylogenetic neighbours showed that it formed a distinct genomic species. The strain was readily distinguished from these organisms using a combination of morphological and phenotypic data. Based on the genotypic and phenotypic results, isolate C2 T represents a novel species in the genus Streptomyces, for which the name Streptomyces bullii sp. nov. is proposed. The type strain is C2 T (=CGMCC 4.7019 T = KACC 15426 T). 相似文献

Two filamentous actinomycetes isolated from a hay meadow soil were provisionally assigned to the genus Streptomyces based on morphological features. The isolates were found to have chemical and morphological properties typical of the genus Streptomyces and formed distinct phyletic lines in the 16S rRNA gene tree. Isolate I36 T was most closely related to Streptomyces glauciniger NBRC 100913 T and isolate I37 T to Streptomyces mirabilis NBRC 13450 T. Low DNA:DNA relatedness values were recorded between each of the isolates and their closest phylogenetic neighbour. The isolates were also distinguished from their nearest phylogenetic neighbour, and from one another, using a combination of phenotypic properties. These data indicate that the isolates should be recognised as new species in the genus Streptomyces. The names proposed for these new taxa are Streptomyces erringtonii sp. nov. and Streptomyces kaempferi sp. nov. with isolate I36 T (=CGMCC 4.7016 T = KACC 15424 T) and isolate I37 T (=CGMCC 4.7020 T = KACC 15428 T) as the respective type strains. 相似文献

A novel anaerobic bacterium (strain M08_MB T) was isolated from a terrestrial mud volcano (Taman Peninsula, Russia). Gram-stain-negative cells were straight and slender rods with gliding motility, occasionally forming long filaments. The isolate was mesophilic, slightly halo- and alkaliphilic chemoorganoheterotroph, growing on carbohydrates (starch, dextrin, pectin, glucose, fructose, mannose, maltose, trehalose, lactose, sucrose) and proteinaceous compounds (peptone, tryptone, gelatin, casein and albumin). Strain M08_MB T tolerated 3% oxygen in the gas phase while catalase negative. The dominant cellular fatty acids of strain M08_MB T were C 15:0, C 15:1 and C 13:0 acids. 16S rRNA gene sequence analysis revealed that strain M08_MB T belongs to the order Bacteroidales and only distantly related to other cultivated members of this order (85.12–90.01% 16S rRNA gene similarity). The genome of strain M08_MB T had a size of 4.37 Mb with a DNA G + C content of 43.5 mol% (WGS). The genes involved in gliding motility, proteolysis, central carbon metabolism, and oxygen tolerance were listed in genome annotation. Based on the phenotypic and genotypic characteristics, strain M08_MB T represents a novel species of a novel genus within family Tenuifilaceae, with proposed name Perlabentimonas gracilis gen. nov., sp. nov. The type strain is M08_ MB T (=DSM 110720 T = VKM B-3471 T). This is the first representative of Bacteroidales isolated in pure culture from a mud volcano. 相似文献

A novel cellulolytic bacterium, strain S23 T, was isolated from the rhizosphere of the pine trees in Daejeon, Republic of Korea. This isolate was Gram-positive, strictly aerobic, rod-shaped, catalase-negative, oxidase-positive, motile by means of peritrichous flagella, and tested positive for alkaline phosphatase, esterase lipase, leucine arylamidase, α-galactosidase, and β-galactosidase activities. The DNA G+C content was 49.5 mol%. The main cellular fatty acids were anteiso-C 15:0 (51.9%), iso-C 16:0 (14.7%), and iso-C 15:0 (13.2%). The major isoprenoid quinone was menaquinone 7 (MK-7). Diagnostic diamino acid in the cell-wall pepti-doglycan was meso-diaminopimelic acid. Comparative 16S rRNA gene sequence analysis showed that this strain clustered with Paenibacillus species. The 16S rRNA gene sequence similarity values between S23 T and other Paenibacillus species were between 89.9% and 95.9%, and S23 T was most closely related to Paenibacillus tarimensis SA-7-6 T. On the basis of phylogenetic and phenotypic properties of strain S23 T, the isolate is considered as a novel species belonging to the genus Paenibacillus. Therefore, the name, Paenibacillus pinihumi sp. nov., is proposed for the rhizosphere isolate; the type strain is S23 T (=KCTC 13695 T =KACC 14199 T =JCM 16419 T) 相似文献
