Abstract

A novel strain, designated HY-50R, isolated from soil of a Euphrates poplar () forest in Xinjiang, China, was characterized using a polyphasic taxonomic approach. Cells of the isolate were Gram-reaction-negative, strictly aerobic, rod-shaped, non-motile, oxidase-negative and catalase-positive. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate was a member of the phylum , its closest relatives being THYL-44 (93.6 % similarity), Gsoil 643 (93.5 %), IAM 15098 (93.3 %) and Gsoil 492 (93.2 %). The major fatty acids were iso-C G (11.7 %), iso-C (19.6 %) and iso-C 3-OH (19.3 %). The predominant menaquinone of strain HY-50R was MK-7 and the genomic DNA G+C content was 46.8 mol%. Flexirubin-type pigments were not produced. Based on phylogenetic evidence and the results of phenotypic, genotypic and chemotaxonomic analysis, strain HY-50R represents a novel species of a novel genus, for which the name gen. nov., sp. nov. is proposed. The type strain is HY-50R ( = CCTCC AB 208255  = NRRL B-59222).
