Abstract

A Gram-reaction-negative, strictly aerobic, non-motile and rod-shaped bacterial strain, AY17, was isolated from the Chishui River in Guizhou Province, South-west China. Strain AY17 grew optimally at pH 7.0 and 20 °C. Flexirubin-type pigments were produced. 16S rRNA gene sequence analysis indicated that strain AY17 belonged to the family within the phylum ; the closest phylogenetic relative was PTJT-5 (95.3 % gene sequence similarity). The DNA G+C content was 49.5 mol%. Strain AY17 contained MK-7 as the predominant respiratory quinone and phosphatidylethanolamine as the major polar lipid. The major fatty acids were iso-C, iso-CG and iso-C 3-OH. On the basis of phylogenetic, phenotypic and genetic data, strain AY17 was classified as representing a novel species of the genus , for which the name sp. nov. is proposed. The type strain is AY17 ( = CGMCC 1.12700 = JCM 19637).
