title: Parasegetibacter luojiensis gen. nov., sp. nov., a member of the phylum Bacteroidetes isolated from a forest soil.
abstract: A novel golden-yellow-coloured strain, designated RHYL-37(T), was isolated from a soil sample from a forest of Euphrates poplar (Populus euphratica) in Xinjiang, China. The cells were strictly aerobic, Gram-staining-negative, heterotrophic, non-spore-forming rods that were motile by gliding. Growth occurred at 17-37 degrees C (optimum, 30 degrees C), at pH 5.0-9.0 (optimum, pH 7.0) and with 0-1 % NaCl (w/v; optimum, 0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the novel isolate formed a cluster with members of the genera Segetibacter, Terrimonas, Niastella, Niabella and Chitinophaga in the family 'Chitinophagaceae' in the phylum Bacteroidetes. Sequence similarities with the type strains of recognized species ranged from 90.6 to 94.0 %. The predominant isoprenoid quinone was MK-7 and the major cellular fatty acids were iso-C(15 : 0), iso-C(15 : 1), C(16 : 0) and iso-C(17 : 0) 3-OH. The DNA G+C content was 39.7 mol%. On the basis of the phylogenetic, physiological and chemotaxonomic data, strain RHYL-37(T) represents a novel genus and species in the family 'Chitinophagaceae', for which the name Parasegetibacter luojiensis gen. nov., sp. nov. is proposed. The type strain of Parasegetibacter luojiensis is RHYL-37(T) (=CCTCC AB 208240(T)=KCTC 22561(T)).
