Abstract

A transparent, non-pigmented, Gram-negative, rod-shaped bacterium, designated strain DS-28, was isolated from water samples collected from a spring located in Tainan County, Taiwan. 16S rRNA gene sequence analysis indicated that the novel strain formed a monophyletic branch at the periphery of the evolutionary radiation occupied by the genus ; the only sole close neighbour of the novel strain was ATCC 19706 (97.4 % 16S rRNA gene sequence similarity). The isolate was distinguished from on the basis of genotypic data, several phenotypic properties and an inability to produce characteristic blue-pigmented colonies on peptone agar. The fatty acid profile was slightly different from that reported for ATCC 19706. It was evident from the genotypic and phenotypic data that strain DS-28 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is DS-28 (=BCRC 17730=LMG 24214).
