Abstract

A yellow-pigmented bacterial strain, designated RIB1-20, isolated from fresh water was investigated by means of a polyphasic taxonomic approach. The cells were Gram-negative, rod-shaped and non-spore-forming. Phylogenetic analyses with the 16S rRNA gene sequence showed that the strain formed a monophyletic branch towards the periphery of the evolutionary radiation occupied by the genus , its two closest neighbours being CC-YY255 (96.1 % sequence similarity) and B1953/27.1 (95.8 %). Strain RIB1-20 was clearly distinguished from both of those type strains using phylogenetic analysis, DNA–DNA hybridization, fatty acid composition data and a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strain RIB1-20 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is RIB1-20 (=BCRC 17731 =LMG 24212).
