Utilizing a three-particle W state, we come up with a protocol for the teleportation of an unknown two-particle entangled state. It is shown that the teleportation can be deterministically and exactly realized. Moreover, two-particle entanglement teleportation is generalized to a system consisting of many particles via a three-particle W state and a multi-particle W state, respectively. All unitary transformations performed by the receiver are given in a concise formula. © 2010 Chinese Physical Society and IOP Publishing Ltd. Source

A Gram-negative bacterium, designated B2-9T, was isolated from water of a slightly alkaline lake, Longhu Lake in Daqing, north-east China. Strain B2-9T was an aerobic rod, heterotrophic, catalase- and oxidase-positive and motile by means of a single polar flagellum. The isolate grew well on n-alkanes C9-C17 and weakly on C 6-C8, C18 and C19. Growth occurred at 10-37 °C (optimum 20-25 °C), at pH 5.5-9.5 (optimum pH 7.0) and with ≤1.0% (w/v) NaCl. The major fatty acids were C18 : 1ω7c (41.4 %), summed feature 3 (iso-C15 : 0 2-OH and/or C 16 : 1ω7c; 18.5 %) and C16 : 0 (10.9 %). Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain B2-9T belonged to the genus Hydrocarboniphaga of the class Gammaproteobacteria and shared 97.0% 16S rRNA gene sequence similarity with Hydrocarboniphaga effusa AP103T. DNA-DNA relatedness between strain B2-9T and H. effusa DSM 16095T was 24 %. The DNA G+C content of strain B2-9T was 66 mol%. Strain B2-9T is considered to represent a novel species of the genus Hydrocarboniphaga, for which the name Hydrocarboniphaga daqingensis sp. nov. is proposed. The type strain is B2-9T (=CGMCC 1.7049T =NBRC 104238T). © 2011 IUMS. Source

The bacterial strain LH2-2T was isolated from freshwater of Longhu Lake, a slightly alkaline lake (pH 8.8) in north-east China. Cells of strain LH2-2T were Gram-staining-negative, non-spore-forming rods, 0.3-0.5 μm wide and 2.0-4.0 μm long. Cells were motile by means of a single polar flagellum. The strain was strictly aerobic and heterotrophic and oxidase- and catalase-positive. Growth occurred at 0-36 °C (optimum, 26-34 °C), pH 6.5-11 (optimum, pH 8.0-8.6) and in the presence of 0-2 % (w/v) NaCl (optimum, 1 %). Strain LH2-2T contained Q-8 as the major respiratory quinone. The major fatty acids were summed feature 3 (C16:1ω7c and/or iso-C15:0 2-OH; 21.9 %), C17:1ω8c (18.9 %), C18:1ω7c (16.4 %) and C16:0 (12.7 %) after growth on marine agar 2216. The DNA G+C content was 47 mol% (Tm). The 16S rRNA gene and a conserved portion of the gyrB gene were sequenced and used for phylogenetic analyses. Phylogenetic trees based on 16S rRNA gene and gyrB sequences showed that strain LH2-2T was associated with the genus Rheinheimera and closely related to the type strains of Rheinheimera species, and showed the highest 16S rRNA gene sequence similarity to Rheinheimera pacifica KMM 1406T (97.4 %), R. aquimaris SW-353T (97.1 %) and R. chironomi K19414T (96.5 %). The DNA-DNA relatedness of strain LH2-2T to R. pacifica NBRC 103167T, R. aquimaris JCM 14331T and R. chironomi LMG 23818T was 39, 31 and 23 %, respectively. Based on these results, it is concluded that strain LH2-2T represents a novel species of the genus Rheinheimera, for which the name Rheinheimera longhuensis sp. nov. is proposed. The type strain is LH2-2T (= CGMCC 1.7003T = NBRC 105632T). An emended description of the genus Rheinheimera is also provided. © 2012 IUMS. Source

A Gram-negative, rod-shaped, non-pigmented, non-spore-forming bacterial strain that was motile by a single polar flagellum, designated A1-9T, was isolated from Daqing reservoir in north-east China and its taxonomic position was studied using a polyphasic approach. Strain A1-9T was non-halophilic, strictly aerobic and heterotrophic and lacked carotenoids, internal membranes and genes for photosynthesis (puf genes). Strain A1-9 T grew at 10-40 °C (optimum, 25-30 °C) and pH 5.5-9.0 (optimum, pH 6.0-6.5) and tolerated up to 1.0% NaCl (w/v). Neither phototrophic nor fermentative growth was observed. The predominant ubiquinone was Q-10 and the major fatty acid was C18 : 1ω7c (70 %). The DNA G+C content was 64.4 mol% (Tm). Phylogenetic analyses based on the 16S rRNA gene sequence revealed that strain A1-9T, together with Catellibacterium nectariphilum AST4T, formed a deep line within the 'Rhodobacter clade' of the family Rhodobacteraceae and strain A1-9T showed 94.2% 16S rRNA gene sequence similarity to C. nectariphilum AST4T. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain A1-9 T is considered to represent a novel species of the genus Catellibacterium, for which the name Catellibacterium aquatile sp. nov. is proposed. The type strain is A1-9T (=CGMCC 1.7029T =NBRC 104254T). © 2010 IUMS. Source
