چکیده
A yellow-pigmented, Gram-reaction-negative, non-motile, aerobic bacterium, designated DR4-30(T), was isolated from tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway (78° 58' N 12° 03' E). Growth occurred at 4-28 °C (optimum 20-25 °C) and at pH 7-8 (optimum pH 7). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain DR4-30(T) belongs to the genus Luteolibacter in the family Verrucomicrobiaceae. The 16S rRNA gene sequence of this strain showed 95.4 and 94.7 % sequence similarity to those of Luteolibacter pohnpeiensis A4T-83(T) and Luteolibacter algae A5J-41-2(T), respectively. The major respiratory quinones were MK-9 and MK-10; the predominant cellular fatty acids were summed feature 3 (C(16 : 1)ω7c and/or C(16 : 1)ω6c; 20.7 %), iso-C(14 : 0) (20.3 %), C(17 : 0) (10.7 %), C(16 : 0) (8.0 %) and C(14 : 0) (6.6 %). The DNA G+C content was 57.3 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain DR4-30(T) represents a novel species of the genus Luteolibacter, for which the name Luteolibacter luojiensis sp. nov. is proposed. The type strain is DR4-30(T) (= CCTCC AB 2010415(T) = NRRL B-59669(T)). An emended description of the genus Luteolibacter is also provided.

Four aerobic bacteria, designated MP5ACTX2(T), MP5ACTX8(T), MP5ACTX9(T) and S6CTX5A(T), were isolated from tundra soil of north-western Finland (69° 03' N 20° 50' E). Cells of all isolates were Gram-negative, non-motile rods.

متن کاملCorrection: The Rhizosphere Selects for Particular Groups of Acidobacteria and Verrucomicrobia
There is a lack in our current understanding on the putative interactions of species of the phyla of Acidobacteria and Verrucomicrobia with plants. Moreover, progress in this area is seriously hampered by the recalcitrance of members of these phyla to grow as pure cultures. The purpose of this study was to investigate whether particular members of Acidobacteria and Verrucomicrobia are avid colo...

A polyphasic study was undertaken to establish the taxonomic position of a rhizosphere isolate that had been assigned provisionally to the genus Kitasatospora. The organism, isolate F18-98(T), was found to have chemical and morphological properties that were consistent with its classification as a Kitasatospora strain. Direct 16S rDNA sequence data confirmed the taxonomic position of the strain...

A novel strain, HY-22R(T), was isolated from soil of a Euphrates poplar forest in Xinjiang, China. The cells were Gram-positive-staining, rod-shaped and motile by means of peritrichous flagella. Growth occurred at 10-37 degrees C (optimum 30 degrees C), at pH 7.0-8.0 (optimum pH 7.0) and with 0-1 % NaCl. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HY-22R(T) was...
