Abstract

A yellow-coloured bacterial strain, designated HB2, isolated from stratum water was investigated using a polyphasic taxonomic approach. Cells were Gram-stain-negative, aerobic, non-spore-forming, non-flagellated and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences showed that the strain was a member of the genus , its three closest neighbours being BCRC 17731 (97.5 % similarity), JCM 12488 (97.3 %) and DSM 19680 (96.9 %). Strain HB2 could clearly be distinguished from these type strains based on phylogenetic analysis, DNA–DNA hybridization, fatty acid composition and a range of physiological and biochemical characteristics. It is evident from the genotypic and phenotypic data that strain HB2 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is HB2 ( = DSM 26429 = CICC 11005s).
