摘要：

A Gram-negative bacterium designated A3(T) was isolated from a potting soil produced in Portugal. This organism formed rod-shaped cells, was non-motile and strictly aerobic. Strain A3(T) was catalase-negative, weakly oxidase positive, with an optimum growth temperature of 40 degrees C and an optimum pH value for growth of 7.0. The predominant cellular fatty acids detected were iso-17:1 w9c, iso-17:0, iso-15:0, iso-16:0 and iso-11:0 3OH and the major respiratory quinone was ubiquinone 8. The G + C content of DNA was 68.3%. The phylogenetic analyses based on the 16S rRNA sequencing showed that the closest relative of strain A3(T) was the type strain of Dokdonella koreensis indicating that the organism is a member of the family Xanthomonadaceae, class Gammaproteobacteria. Based on the phylogenetic analyses and distinct phenotypic characteristics, we are of the opinion that strain A3(T), represents a novel species of the genus Dokdonella for which we propose the name Dokdonella fugitiva sp.nov.
