Luteimonas huabeiensis sp. nov., isolated from stratum water

Abstract

A yellow-coloured bacterial strain, designated HB2T, 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 Luteimonas , its three closest neighbours being Luteimonas aquatica BCRC 17731T (97.5 % similarity), Luteimonas marina JCM 12488T (97.3 %) and Luteimonas aestuarii DSM 19680T (96.9 %). Strain HB2T 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 HB2T represents a novel species of the genus Luteimonas , for which the name Luteimonas huabeiensis sp. nov. is proposed. The type strain is HB2T ( = DSM 26429T = CICC 11005sT).
