Abstract:

ABSTRACT A novel sphingoglycolipid was isolated from Sphingomonas yanoikuyae, and its structure was identified as a galacturonosyl-β (1→1)-ceramide. This was a characteristic sphingoglycolipid present in S. yanoikuyae and certain other species of Sphingomonas, such as Sphingomonas mali, Sphingomonas terrae, and Sphingomonas macrogoltabidus, but not in the type species ofSphingomonas, Sphingomonas paucimobilis.

Abstract:

‘ Caulobacter leidyi ’ DSM 4733T has been shown to be affiliated with the family Sphingomonadaceae instead of the Caulobacteraceae , and due to its poor characterization has been omitted from the current edition of Bergey’s Manual of Systematic Bacteriology and removed to limbo. We isolated a novel sphingoglycolipid-containing dimorphic prosthecate bacterium, designated strain 247, from a pre-alpine freshwater lake. Strain 247 and ‘ Caulobacter leidyi ’ DSM 4733T were characterized in detail. The rod-shaped cells were Gram-stain-negative, aerobic, catalase- and oxidase-positive, and formed a stalk or polar flagellum. Both strains grew optimally at 28–30 °C, and pH 6.0–8.0. The major fatty acids were C18 : 1ω7c, C16 : 0 and 11-methyl C18 : 1ω7c. C14 : 0 2-OH represents the major 2-hydroxy fatty acid. Q-10 was the major respiratory quinone and the major polar lipids were diphosphatidylglycerol, phosphatidyldimethylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, phosphatidylcholine, three glycolipids, two phosphoaminolipids and two unidentified sphingoglycolipids. The major polyamine was sym-homospermidine. The G+C content of genomic DNA of strains 247 and DSM 4733T was 67.6 mol% and 67.0 mol%, respectively. According to 16S rRNA gene sequence analysis and DNA–DNA hybridization, strains DSM 4733T and 247 were phylogenetically closely related (99.6 % 16S rRNA gene sequence similarity, 82.9 % DNA–DNA hybridization value) and affiliated to the genus Sphingomonas . The closest recognized species was Sphingomonas aquatilis DSM 15581T (98.1 % sequence similarity). In addition, the presence of cystine arylamidase, absence of β-galactosidase, and the inability to utilize l-arabinose, galactose and sucrose distinguished strains DSM 4733T and 247 from most other members of the family Sphingomonadaceae . So far, the dimorphic life cycle that involves a prosthecate and a flagellated stage is unique for strains DSM 4733T and 247 among all members of the family Sphingomonadaceae . Therefore, Caulobacter leidyi is reclassified as Sphingomonas leidyi, with the type strain DSM 4733T ( = ATCC 15260T = CIP 106443T = VKM B-1368T) and strain 247 (DSM 25078 = LMG 26658) as an additional strain of this species.

Abstract:

A polycyclic aromatic hydrocarbons-degrading and acylhomoserine-lactone-producing marine bacterium, designated strain PQ-2T, was isolated from marine biofilm collected from a boat shell at a harbour of Zhoushan island in Zhejiang Province, PR China. Strain PQ-2T is Gram-stain-negative, yellow-pigmented, non-motile and short rod-shaped. Optimal growth of strain PQ-2T was observed at 32 °C, at pH 7.0 and in 2 % (w/v) NaCl. The 16S rRNA gene sequence of strain PQ-2T showed highest similarity to Croceicoccus marinus E4A9T (96.3 %) followed by Novosphingobium malaysiense MUSC 273T (95.6 %) and Altererythrobacter marinus H32T (95.6 %). Phylogenetic analysis with all species of the family Erythrobacteraceae with validly published names revealed that strain PQ-2T formed a phyletic line with Croceicoccus marinus E4A9T that was distinct from other members of the family Erythrobacteraceae . The sole respiratory quinone was ubiquinone 10 (Q-10). The predominant fatty acids were C18 : 1ω7c, C17 : 1ω6c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The genomic DNA G+C content was 61.7 mol%. In the polar lipid profile, phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, one unidentified phospholipid and one sphingoglycolipid were the major compounds; and another sphingoglycolipid was present in a minor amount. Based on the genotypic and phenotypic data, strain PQ-2T represents a novel species of the genus Croceicoccus , for which the name Croceicoccus naphthovorans sp. nov. is proposed. The type strain is PQ-2T ( = CGMCC 1.12805T = NBRC 110381T). In addition, emended descriptions for the genus Croceicoccus and the species C. marinus are given.

Abstract:

A yellow-pigmented bacterial strain, designated LL01T, was isolated from hexachlorocyclohexane (HCH)-contaminated soil at Spolana Neratovice, a former Czech producer of lindane. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL01T occupied a distinct phylogenetic position in the Sphingobium cluster, showing highest similarity to Sphingobium rhizovicinum CC-FH12-1T (98.5 %). The DNA G+C content of strain LL01T was 66.1 mol%. The predominant respiratory pigment was ubiquinone Q-10. The polar lipid profile of strain LL01T also corresponded to those reported for other Sphingobium species (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, sphingoglycolipids), supporting its identification as a member of the genus Sphingobium . Spermidine was the major polyamine observed. The results obtained from DNA–DNA hybridization and biochemical and physiological tests clearly distinguished strain LL01T from closely related species of the genus Sphingobium . Therefore, strain LL01T represents a novel species of the genus Sphingobium , for which the name Sphingobium czechense sp. nov. is proposed (type strain LL01T = CCM 7979T = DSM 25410T).

Abstract:

A bacterial strain, JLT2016T, was isolated from a sample of South-eastern Pacific deep-sea water. Cells were Gram-stain-negative, aerobic, devoid of flagella, motile by gliding and rod-shaped. Colonies were mucoid and cream. Growth occurred at 1.0–11.0 % (w/v) NaCl, 10–40 °C and pH 4.0–9.0. The major fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) (60.5 %), C19 : 0 cyclo ω8c (10.9 %) and C16 : 0 (9.0 %). The polar lipids included diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and two sphingoglycolipids. The DNA G+C content was 67.1 mol%. The closest relative of strain JLT2016T was Salipiger mucosus A3T (96.7 % 16S rRNA gene sequence similarity). The results of phylogenetic analyses with different treeing algorithms indicated that this strain belonged to the Roseobacter clade in the order Rhodobacterales . Based on polyphasic analysis, strain JLT2016T is considered to represent a novel genus and species, for which the name Thiobacimonas profunda gen. nov., sp. nov. is proposed. The type strain is JLT2016T ( = LMG 27365T = CGMCC 1.12377T).

Abstract:

A Gram-negative, motile, non-spore-forming bacterial strain, designated HU1-GD12T, was isolated from freshwater sediment. The strain was characterized by using a polyphasic approach in order to determine its taxonomic position. Comparative analysis of the 16S rRNA gene sequence showed that the isolate constituted a distinct branch within the genus Sphingobium, showing the highest level of sequence similarity with respect to Sphingobium ummariense RL-3T (96.2 %). Strain HU1-GD12T had a genomic DNA G+C content of 66.8 mol% and Q-10 as the predominant respiratory quinone. Furthermore, the major polyamine component (spermidine) in the cytoplasm and the presence of sphingoglycolipids suggested that strain HU1-GD12T belonged to the family Sphingomonadaceae. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain HU1-GD12T represents a novel species of the genus Sphingobium, for which the name Sphingobium vulgare sp. nov. is proposed. The type strain is HU1-GD12T (=LMG 24321T=KCTC 22289T).

Strain T5-04T, a Gram-negative, non-spore-forming, rod-shaped bacterium, was isolated from soil of a ginseng field in South Korea and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain T5-04T belongs to the α-4 subgroup of the Proteobacteria, and the highest degrees of sequence similarity determined were to Sphingomonas asaccharolytica IFO 10564T (97·5 %), Sphingomonas koreensis JSS26T (97·1 %), Sphingomonas mali IFO 15500T (96·7 %) and Sphingomonas pruni IFO 15498T (96·6 %). Chemotaxonomic data revealed that strain T5-04T possesses ubiquinone Q-10 predominantly, C18 : 1 as the predominant fatty acid and sphingoglycolipids, all of which corroborate its assignment to the genus Sphingomonas. The results of DNA–DNA hybridization and physiological and biochemical tests clearly demonstrated that strain T5-04T represents a distinct species. Based on polyphasic evidence, T5-04T (=KCTC 12210T=NBRC 100801T=IAM 15213T) should be classified as the type strain of a novel Sphingomonas species, for which the name Sphingomonas soli sp. nov. is proposed.

Abstract:

Sulfatides are one of the major sphingoglycolipids in mammalian serum and are synthesized and secreted mainly from the liver as a component of lipoproteins. Recent studies revealed a protective role for serum sulfatides against arteriosclerosis and hypercoagulation. Although peroxisome proliferator-activated receptor (PPAR)αhas important functions in hepatic lipoprotein metabolism, its association with sulfatides has not been investigated. In this study, sulfatide levels and the expression of enzymes related to sulfatide metabolism were examined using wild-type (+/+),Ppara-heterozygous (+/−), andPpara-null (−/−) mice given a control diet or one containing 0.1% fenofibrate, a clinically used hypolipidemic drug and PPARαactivator. Fenofibrate treatment increased serum and hepatic sulfatides inPpara(+/+) and (+/−) mice through a marked induction of hepatic cerebroside sulfotransferase (CST), a key enzyme in sulfatide synthesis, in a PPARα-dependent manner. Furthermore, increases in CST mRNA levels were correlated with mRNA elevations of several known PPARαtarget genes, and such changes were not observed for other sulfatide-metabolism enzymes in the liver. These results suggest that PPARαactivation enhances hepatic sulfatide synthesis via CST induction and implicate CST as a novel PPARαtarget gene.

Abstract:

A Gram-negative, non-motile, non-spore-forming, halophilic rod, designated JPCCMB0017T, was isolated from a marine sediment of the coastal area of Okinawa, Japan. The isolate formed orange–red colonies on marine agar. Bacteriochlorophyll α was absent and sphingoglycolipid 1 and other carotenoids, including astaxanthin, adonixanthin and zeaxanthin, were present. Ubiquinone-10 (Q-10) was the main respiratory quinone and C18 : 1ω7c was the major cellular fatty acid. The G+C content of DNA was 59.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the isolate was a member of the genus Altererythrobacter in the family Erythrobacteraceae. Strain JPCCMB0017T exhibited 96.8 % 16S rRNA gene sequence similarity with Altererythrobacter marinus H32T. Unlike other members of the genus Altererythrobacter, strain JPCCMB0017T reduced nitrate. On the basis of genotypic and phenotypic data, a novel species is proposed to accommodate this isolate, with the name Altererythrobacter ishigakiensis sp. nov. The type strain is JPCCMB0017T ( = NITE-AP48T = ATCC BAA-2084T = NBRC 107699T).

Abstract:

The taxonomic status of a yellow-coloured bacterial isolate from an oil-contaminated soil sample was determined using a polyphasic taxonomic approach. Comparative analysis of 16S rRNA gene sequences showed that the novel isolate formed a distinct phyletic line within the genus Sphingobium. The generic assignment was confirmed by chemotaxonomic data, which revealed: a fatty acid profile that is characteristic of the genus Sphingobium consisting of straight-chain saturated and unsaturated as well as 2-OH fatty acids; a ubiquinone with ten isoprene units (Q-10) as the predominant respiratory quinone; a polar lipid pattern consisting of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidylcholine and sphingoglycolipid, and spermidine as the major polyamine component. Genotypic and phenotypic data show that the new isolate merits classification as a representative of a novel species of the genus Sphingobium, for which the name Sphingobium olei sp. nov. is proposed. The type strain is IMMIB HF-1T (=DSM 18999T=CCUG 54329T).

A bacterial strain capable of degrading pyrethroid, designated JZ-2T, was isolated from activated sludge treating pyrethroid-contaminated wastewater. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain JZ-2T belongs to the genus Sphingobium. It showed the highest levels of 16S rRNA gene sequence similarity to Sphingobium cloacae JCM 10874T (98.3 %) and Sphingobium ummariense CCM 7431T (97.1 %), and 94.8–96.9 % similarity to the type strains of other members of the genus Sphingobium. Strain JZ-2T contained C18 : 1 ω7c as the predominant fatty acid, C14 : 0 2-OH as the major 2-hydroxy fatty acid, ubiquinone Q-10 as the main respiratory quinone, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylmonomethylethanolamine, phosphatidylethanolamine and two sphingoglycolipids as the predominant polar lipids and spermidine as the major polyamine. DNA–DNA hybridization results showed that strain JZ-2T had low genomic relatedness with S. cloacae JCM 10874T (34 %) and S. ummariense CCM 7431T (23 %). Based on the phenotypic, genotypic and phylogenetic data presented, strain JZ-2T is considered to represent a novel species of the genus Sphingobium, for which the name Sphingobium faniae sp. nov. is proposed. The type strain is JZ-2T (=CGMCC 1.7749T =DSM 21829T).

Abstract:

Strain Kp5.2T is an aerobic, Gram-negative soil bacterium that was isolated in Freiberg, Saxony, Germany. The cells were motile and rod-shaped. Optimal growth was observed at 20–30 °C. The fatty acids of strain Kp5.2T comprised mainly C18 : 1ω7c and summed feature 3 (C16 : 1ω7c/iso-C15 : 0 2-OH). The major respiratory quinone was Q-10. The major polar lipids of strain Kp5.2T were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. The G+C content of the genomic DNA was 63.7 %. Sequencing of the 16S rRNA gene of strain Kp5.2T allowed its classification into the family Sphingomonadaceae, and the sequence showed the highest similarity to those of members of the genus Sphingopyxis, with Sphingopyxis italica SC13E-S71T (99.15 % similarity), Sphingopyxis panaciterrae Gsoil 124T (98.96 %), Sphingopyxis chilensis S37T (98.90 %) and Sphingopyxis bauzanensis BZ30T (98.51 %) as the nearest neighbours. DNA–DNA hybridization and further characterization revealed that strain Kp5.2T can be considered to represent a novel species of the genus Sphingopyxis. Hence, the name Sphingopyxis fribergensis sp. nov. is proposed, with the type strain Kp5.2T ( = DSM 28731T = LMG 28478T).

Abstract:

A yellow-pigmented, hexachlorocyclohexane (HCH)-degrading bacterium, designated F2T, was isolated from an HCH dumpsite at Ummari village in Lucknow, India. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate belonged to the genus Sphingobium. Its closest neighbour was Sphingobium japonicum UT26T (99.2 % 16S rRNA gene sequence similarity). The DNA G+C content was 65.7 mol%. The polyamine profile showed the presence of spermidine. The respiratory pigment was ubiquinone Q-10. The predominant cellular fatty acids were C16 : 0 (12.5 %), C14 : 0 2-OH (8.1 %), summed feature 3 (consisting of C16 : 1ω7c and/or C16 : 1ω6c; 5.8 %) and summed feature 8 (consisting of C18 : 1ω7c and/or C18 : 1ω6c; 53.1 %). The major polar lipids of strain F2T were phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and sphingoglycolipid. DNA–DNA relatedness and biochemical and physiological characters clearly distinguished the isolate from its closest phylogenetic neighbours. Thus, strain F2T represents a novel species of the genus Sphingobium, for which the name Sphingobium lucknowense sp. nov. is proposed. The type strain is strain F2T ( = MTCC 9456T = CCM 7544T).

A yellow‐pigmented, Gram-negative rod, designated FNE08-86T, was isolated from subsurface water of the humic-matter-rich and almost-neutral north-east basin of the experimentally divided bog lake Grosse Fuchskuhle (Brandenburg, Germany). Analysis of the nearly full-length 16S rRNA gene sequence showed the highest 16S rRNA gene sequence similarity with Novosphingobium rosa IAM 14222T (96.3 %). Sequence similarities with all other members of the genus Novosphingobium species were <96 %, but phylogenetic tree construction clearly showed the placement of strain FNE08-86T within the genus Novosphingobium . The predominant fatty acids were C18 : 1ω7c and C16 : 0, and only a single 2-hydroxy fatty acid, C14 : 0 2-OH, was detected. The polar lipid profile revealed phosphatidylethanolamine, phosphatidylglycerol and phosphatidylcholine as major compounds, with smaller amounts of sphingoglycolipid, phosphatidylmonomethylethanolamine, diphosphatidylglycerol and several unidentified lipids. In the quinone system ubiquinone Q-10 was predominant and in the polyamine pattern spermidine was predominant. Characterization by genotypic, chemotaxonomic and phenotypic analysis indicated that strain FNE08-86T represents a novel species of the genus Novosphingobium , for which we propose the name Novosphingobium aquaticum sp. nov.

The isolate grew optimally at 30 °C and in the presence of 2–3 % NaCl. Strain SW-151T was characterized chemotaxonomically as having Q-10 as the predominant respiratory lipoquinone and C18 : 1 ω7c, C16 : 1 ω7c and/or iso-C15 : 0 2-OH and C17 : 1 ω6c as the major fatty acids. Sphingoglycolipid, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine were the major polar lipids. The DNA G+C content was 58 mol%. 16S rRNA gene sequence analysis showed that strain SW-151T joins the evolutionary radiation enclosed by the genus Sphingopyxis. Similarities between the 16S rRNA gene sequences of strain SW-151T and the type strains of Sphingopyxis species ranged from 92·3 to 94·3 %, which is low enough to categorize strain SW-151T as a species distinct from previously described Sphingopyxis species. On the basis of phenotypic properties and phylogenetic distinctiveness, strain SW-151T (=KCTC 12232T=DSM 16223T) should be classified as a novel Sphingopyxis species, for which the name Sphingopyxis flavimaris sp. nov. is proposed.

The highest 16S rRNA gene sequence similarity observed for the isolate was 96.6 % with the type strain of Sphingobium amiense. Chemotaxonomic data [major ubiquinone: Q-10; major polar lipids: diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, sphingoglycolipid, phosphatidylethanolamine and unknown aminolipids and phospholipids; major fatty acids: summed feature 7 (C18 : 1 ω7c, C18 : 1 ω9t and/or C18 : 1 ω12t), C16 : 1 ω5c, C14 : 0 2-OH and C16 : 0 2-OH] as well as the inability to reduce nitrate and the presence of spermidine as the major polyamine supported the affiliation of the strain to the genus Sphingobium. Based on the phylogenetic analysis, whole-cell fatty acid composition and biochemical characteristics, the strain could be separated from all recognized species of the genus Sphingobium. Strain X23T should be classified as a novel species of the genus Sphingobium, for which the name Sphingobium qiguonii sp. nov. is proposed, with strain X23T (=CCTCC AB 208221T =DSM 21541T) as the type strain.

Abstract:

A non-motile, rod-shaped, yellow bacterium, designated C16yT, was isolated from alpine glacier cryoconite. Cells behaved Gram-positively, were aerobic and psychrophilic (good growth at 1–25 °C). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain C16yT was related to the genus Sphingomonas and had highest 16S rRNA gene sequence similarity with Sphingomonas oligophenolica JCM 12082T (97.6 %) and Sphingomonas echinoides DSM 1805T (97.2 %). DNA–DNA hybridization demonstrated that strain C16yT could not be considered as a member of either Sphingomonas oligophenolica or Sphingomonas echinoides. Strain C16yT contained Q-10 as the predominant ubiquinone and C18 : 1 and C16 : 0 were the dominant fatty acids. The polar lipid profile contained phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, sphingoglycolipid, five unidentified glycolipids, two unidentified aminophospholipids and two unidentified lipids. The major polyamines were the triamines sym-homospermidine and spermidine. The G+C content was 67.9 mol%. Combined data from phenotypic, phylogenetic and DNA–DNA relatedness studies demonstrated that strain C16yT is a representative of a novel species of the genus Sphingomonas, for which we propose the name Sphingomonas glacialis sp. nov. The type strain is C16yT (=DSM 22294T =CGMCC 1.8957T =CIP 110131T).

Abstract:

Two Gram-reaction-negative, yellow–orange-pigmented, rod-shaped bacterial strains, designated YC6722T and YC6723T, were isolated from rhizosphere soil samples collected from rice fields in Jinju, Korea. Strains YC6722T and YC6723T grew optimally at 25–30 °C and at pH 7.0–8.5. Phylogenetic analyses of 16S rRNA gene sequences showed that strain YC6722T was most closely related to Sphingomonas jaspsi TDMA-16T (96.6 % sequence similarity) and strain YC6723T was related most closely to Sphingomonas aquatilis JSS7T (96.9 %). The two strains contained ubiquinone-10 (Q-10) as the major respiratory quinone system and sym-homospermidine as the major polyamine. The G+C contents of the genomic DNA of strains YC6722T and YC6723T were 63.3 and 61.0 mol%, respectively. The major fatty acid was C18 : 1ω7c. The polar lipids detected in the two strains were phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, sphingoglycolipid, phosphatidyldimethylethanolamine and other unknown lipids. On the basis of their phylogenetic positions, and their biochemical and phenotypic characteristics, strains YC6722T and YC6723T represent two novel species of the genus Sphingomonas, for which the names Sphingomonas oryziterrae sp. nov. ( = KCTC 22476T = DSM 21455T) and Sphingomonas jinjuensis sp. nov. (KCTC 22477T = DSM 21457T) are proposed.

Abstract:

A Gram-stain-negative, rod-shaped bacterium, designated strain YC7378T was isolated from vermicompost (VC) collected at Masan, Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain YC7378T grew optimally at 30 °C and at pH 6.5–8.5. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain YC7378T belongs to the genus Sphingosinicella in the family Sphingomonadaceae. The most closely related strains are Sphingosinicella soli KSL-125T (95.7 %), Sphingosinicella xenopeptidilytica 3-2W4T (95.6 %) and Sphingosinicella microcystinivorans Y2T (95.5 %). Strain YC7378T contained ubiquinone Q-10 as the major respiratory quinone system and sym-homospermidine as the major polyamine. The major fatty acids of strain YC7378T were C18 : 1 ω7c, C16 : 1 ω7c and/or iso-C15 : 0 2-OH, C14 : 0 2-OH and C16 : 0. The major polar lipids were sphingoglycolipid, diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The total DNA G+C content was 59.4 mol%. The phenotypic, phylogenetic and chemotaxonomic data showed that strain YC7378T represents a novel species of the genus Sphingosinicella, for which the name Sphingosinicella vermicomposti sp. nov. is proposed. The type strain is YC7378T (=KCTC 22446T =DSM 21593T).

Abstract:

A Gram-staining-negative, strictly aerobic, non-motile strain, SYSUP0001T, was isolated from tubers of Gastrodia elata Blume. The 16S rRNA gene sequence result indicated that SYSUP0001T represents a member of the genus Sphingomonas , with the highest sequence similarity (97.7 %) to the type strain of Sphingomonas ginsengisoli . SYSUP0001T grew at 14–37 °C and pH 6–8, with optimum growth at 28 °C and pH 7. Tolerance to NaCl was up to 3 % (w/v) with optimum growth in the absence of NaCl. The respiratory quinone was Q-10. The major fatty acids were C18 : 1ω7c, Summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), and C16 : 0. The polar lipids were diphosphatidylglycerol (DPG), phosphatidylethanolamine (PE), phosphatidylglycerol (PG), sphingoglycolipid (SGL), phosphatidylcholine (PC) and four unidentified polar lipids (L). The DNA G+C content was 67.5 %. The average nucleotide identity (ANI) values between SYSUP0001T and closely related members of the genus Sphingomonas were below the cut-off level (95–96 %) for species delineation. On the basis of the phenotypic, phylogenetic and chemotaxonomic characterizations, SYSUP0001T represents a novel species of the genus Sphingomonas , for which the name Sphingomonasmesophila sp. nov. is proposed. The type strain is SYSUP0001T (=KCTC 62179 T=CGMCC 1.16462T).

Abstract:

A Gram-stain-negative, short rod-shaped, yellow bacterium (strain LMO-1T) was isolated from deep-sea sediment of the Mariana Trench, Challenger Deep. Phylogenetic analysis based on the 16S rRNA gene sequence showed that strain LMO-1T belonged to genus Sphingomonas , with the highest sequence similarity to Sphingomonas formosensis CC-Nfb-2T (96.3 %), followed by Sphingomonas prati W18RDT (96.1 %), Sphingomonas arantia 6PT (96.0 %) and Sphingomonas montana W16RDT (95.9 %). The predominant polar lipids were phosphatidylethanolamine, sphingoglycolipid, phosphatidylglycerol and phosphatidylcholine. The main cellular fatty acids were summed feature 8 (C18 : 1 ω7c and/or C18 : 1 ω6c), C16 : 0 and C14 : 0 2-OH. The major polyamine was sym-homospermidine and the predominant isoprenoid quinone was ubiquinone-10. The genome DNA G+C content of strain LMO-1T was 69.2 mol%. The average nucleotide identity and DNA–DNA hybridization values between strain LMO-1T and CC-Nfb-2T were 75.9 and 20.5 %, respectively. Based on these data, LMO-1T should be classified as representing a novel species of the genus Sphingomonas , for which the name Sphingomonas profundi sp. nov. is proposed. The type strain is LMO-1T (=MCCC 1K04066T=JCM 33666T).

Abstract:

A Gram-reaction-negative, non-motile, facultatively aerobic bacterium, designated strain M1T, was isolated from a subterrestrial sediment sample of Qiangtang Basin in Qinghai-Tibetan plateau, China. The strain formed rough yellow colonies on R2A plates. Cells were oval or short rod-shaped, catalase-positive and oxidase-negative. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the isolate belonged to the family Erythrobacteraceae and showed 96.2–96.4 % 16S rRNA gene sequence similarities to its closest relatives. Chemotaxonomic analysis revealed ubiquinone-10 (Q10) as the dominant respiratory quinone of strain M1T and C17 : 1ω6c (44.2 %) and C18 : 1ω7c (13.7 %) as the major fatty acids. The major polar lipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, sphingoglycolipid, three unidentified glycolipids, one unidentified phosphoglycolipid and one unidentified lipid. The DNA G+C content of strain M1T was 73.7 mol%. On the basis of phenotypic, phylogenetic and genotypic data presented in this study, strain M1T represents a novel species of a new genus in the family Erythrobacteraceae, for which the name Qipengyuania sediminis gen. nov., sp. nov. is proposed. The type strain of the type species is M1T ( = CGMCC 1.12928T = JCM 30182T).

Abstract:

ABSTRACT The Leishmania pifanoi amastigote antigen P-8 has been previously shown to induce protective immunity in a murine model of cutaneous leishmaniasis (L. Soong, S. M. Duboise, P. Kima, and D. McMahon-Pratt, Infect. Immun. 63:3559–3566, 1995). As this antigen is of interest for further vaccine studies, the biochemical characterization of P-8 was undertaken. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis, Western-blot analysis, and gel filtration chromatography revealed that P-8 antigen consisted of two proteoglycolipid complexes. The P-8 epitope is associated with theL. pifanoi amastigote-specific glycolipid components found in the two complexes. The P-8 complex 1 (P-8c1) consists of a 56-kDa serine metalloproteinase, apolipoprotein E (derived from fetal bovine serum), and amastigote-specific glycolipids. The P-8 complex 2 (P-8c2) consists of a 31-kDa cysteine proteinase associated with amastigote glycolipids. Biochemical analyses suggest that the P-8 antigenic glycolipids may be distinct from previously describedLeishmania glycolipids (glycosylinositolphospholipids and sphingoglycolipids). Protective immunity studies revealed that P-8c1 (serine metalloproteinase-glycolipid complex) confers comparable protection against infection as immunopurified P-8. The isolated P-8c2 (cysteine proteinase-glycolipid complex) does not provide significant protection, nor does stimulation with P-8c2 result in significant T-cell activation in P-8- or P-8c2-vaccinated mice. Consequently, the P-8c1 complex appears to be the immunodominant component of P-8.

Abstract:

A yellow-pigmented bacterial strain, designated LL02T, was isolated from hexachlorocyclohexane-contaminated soil from Spolana Neratovice, a former Czech producer of lindane. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL02T occupied a distinct phylogenetic position in the genus Novosphingobium and showed the highest sequence similarity with Novosphingobium resinovorum NCIMB 8767T (98.59 %). DNA–DNA relatedness between strain LL02T and its closest phylogenetic neighbours was <70 %, which indicated that strain LL02T represented a novel species of the genus Novosphingobium . The DNA G+C content of strain LL02T was 67.72±0 mol%. The major respiratory quinone was ubiquinone Q-10. The polar lipid profile of the isolate corresponded to those reported for other members of the genus Novosphingobium (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and sphingoglycolipids), thus supporting its classification in the genus. Spermidine was the major polyamine. The major fatty acids were summed feature 3 (consisting of C16 : 1ω7c and/or C16 : 1ω6c; 40.13 %), summed feature 8 (consisting of C18 : 1ω7c and/or C18 : 1ω6c; 31.09 %) and C14 : 0 2-OH (23.16 %). The results obtained from DNA–DNA hybridization and biochemical and physiological tests clearly distinguished the isolate from its closest phylogenetic neighbours. Thus, strain LL02T represents a novel species of the genus Novosphingobium , for which the name Novosphingobium barchaimii sp. nov. is proposed. The type strain is LL02T ( = CCM 7980T = DSM 25411T).
