Abstract

A novel bacterial strain, designated THYL-44, was isolated from the soil of a Euphrates poplar () forest in Xinjiang, China. The cells were strictly aerobic, Gram-staining-negative, non-flagellated, non-motile and filamentous. Growth occurred at 17–37 °C (optimum 30 °C), at pH 5.0–8.0 (optimum pH 7.0) and with 0–1 % NaCl (w/v; optimum 0 %). Flexirubin pigments were not produced. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain THYL-44 was closely related to KACC 11465 (95.5 % sequence similarity). The major respiratory quinone was MK-7 and the predominant cellular fatty acids were iso-C (28.6 %), iso-C 3-OH (23.9 %) and iso-C G (17.4 %). The DNA GC content was 45.2 mol%. Therefore, the phylogenetic, physiological and chemotaxonomic data demonstrated that strain THYL-44 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is THYL-44 (=CCTCC AB 208238=KCTC 22560). On the basis of new data, an emended description of the genus is also proposed.
