Abstract

A Gram-negative, non-motile, non-spore-forming, rod-shaped bacterium (strain Y9) was isolated from a contaminated culture of the phototrophic bacterium , and was investigated using a polyphasic taxonomic approach. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain Y9 belonged to the order in the . Comparison of phylogenetic data indicated that it was most closely related to (98.5 % similarity of 16S rRNA gene sequence), and the phylogenetic distance from any other species of the order with a validly published name was greater than 7.5 % (i.e. less than 92.5 % similarity). The predominant ubiquinone was Q-10 and the major fatty acids were C, C, C cyclo 8 and C. The G+C content of genomic DNA of strain Y9 was 65.1 mol%. The results of DNA–DNA hybridization in combination with chemotaxonomic and physiological data demonstrated that strain Y9 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is Y9 (=KCTC 12246=NBRC 100803)
