Abstract

A novel golden-yellow-coloured strain, designated RHYL-37, was isolated from a soil sample from a forest of Euphrates poplar () 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 °C (optimum, 30 °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 , , , and in the family ‘’ in the phylum . 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, iso-C, C and iso-C 3-OH. The DNA GC content was 39.7 mol%. On the basis of the phylogenetic, physiological and chemotaxonomic data, strain RHYL-37 represents a novel genus and species in the family ‘’, for which the name gen. nov., sp. nov. is proposed. The type strain of is RHYL-37 (=CCTCC AB 208240=KCTC 22561).
